Kworld DVB-T 210 - dvb tuning problem

Hi Hartmut,
OK, found some more spare time, but very, very frustrated!

1) Tried ubuntu 7.04, 7.10, 8.04
Tried with just modules that exist in kernel (no v4l-dvb)
Tried v4l-dvb from June 2007 and tried current v4l-dvb
Tried with/without Hartmut patch - changeset 7376 49ba58715fe0
Tried with .gpio_config = TDA10046_GP11_I, or .gpio_config =
TDA10046_GP01_I,
Tried using configs in saa7134-dvb.c matching tiger, tiger_s,
pinnacle 310i, twinhan 3056

    # Australia / Perth (Roleystone transmitter)
    # T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
    # SBS
    T 704500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
    # ABC
    T 725500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE

    # Ten
    T 788500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE

2) I have these saa7134 cards:
- pinnacle 310i
- kworld 210

This cx88 card:
- dvico DVB-T Pro hybrid (analog tv not work)

- problem only occurs with kworld 210 in linux (works fine in WinXP)

3) In WinXP, all channels, both analog tv and dvb-t found

4) In linux, if start dvb-t first, never scans SBS - dmesg1

5) In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS - dmesg2

6) Herman mentioned something called a "mode-switch" in the archives, but not any description.

I tried to find some data sheets for tda8275 tda8290 but only found the publicity pdf file from Phillips,
so at least I can see they go together, so I presume this "mode-switch" is coded into those modules.
But those modules work for all other cards, so now I'm lost again.

What else should I try?

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled tuner chip... This means that your initial config file is ok...
b) Does this mean that in case 4, all other channels are found?
c) Case 5: This finds everything?
d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.

f) the kernel logs are as expected.

Recently i saw another card that does the (unusual) mode switching like card 87. So to be sure, you might try to force this card type (be aware of the antenna inputs, if in doubt, try both.

For the Medion8800 Quad and CTX948 also showing this issue, needs to tune analog first to have good recepton on DVB-T, they are a little weaker on analog than other cards, but after that on DVB-T, they are as good than known good others.

Hi Hartmut and Hermann,

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled tuner chip... This means that your initial config file is ok...

Answer - Yes, the non-working remote (and constant unknown key messages) is all that is
wrong with the pinnacle 310i.
I tested it for your new tda8290 tda8275 patches - didn't I send you the results?
It works fine!

b) Does this mean that in case 4, all other channels are found?

Answer - In linux, if start dvb-t first, never scans SBS
- yes all other channels are viewable/scannable.

c) Case 5: This finds everything?

Answer - In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS
- yes all channels are viewable/scannable.

d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.

Answer - the same answer applies as for b) and c)

e) Just to be sure: did you clarify the open point with .antenna_switch (i think so)

Answer - yes that was me being over-enthusiastic - made no difference as you pointed out.

OK, this modification has achieved, I think success. I can now view/scan all channels
in analog tv or dvb-t in either order.
That is, I now don't have to start analog tv first, before dvb-t will start.

In saa7134- cards.c - no change.

In saa7134-dvb.c:

Remove this:
------------------------------------

static struct tda1004x_config kworld_dvb_t_210_config = {
   .demod_address = 0x08,
   .invert        = 1,
   .invert_oclk   = 0,

   .tuner_address = 0x61,
   .antenna_switch= 1,
   .request_firmware = philips_tda1004x_request_firmware
};

------------------------------

Add this:

------------------------------
static int kw210_tuner_init(struct dvb_frontend *fe)

{
   struct saa7134_dev *dev = fe->dvb->priv;
   philips_tda827x_tuner_init(fe);
   /* route TDA8275a AGC input to the channel decoder */
   saa7134_set_gpio(dev, 22, 1);
   return 0;
}

{

   /* route TDA8275a AGC input to the analog IF chip*/
   saa7134_set_gpio(dev, 22, 0);
   philips_tda827x_tuner_sleep(fe);
   return 0;
}

static struct tda827x_config kw210_cfg = {
   .tuner_callback = saa7134_tuner_callback,
   .init = kw210_tuner_init,
   .sleep = kw210_tuner_sleep,
   .config = 0
};

static struct tda1004x_config kworld_dvb_t_210_config = {
   .demod_address = 0x08,
   .invert        = 1,
   .invert_oclk   = 0,
   .xtal_freq     = TDA10046_XTAL_16M,
   .agc_config    = TDA10046_AGC_TDA827X,
   .gpio_config   = TDA10046_GP11_I,
   .if_freq       = TDA10046_FREQ_045,
   .tuner_address = 0x61,
   .request_firmware = philips_tda1004x_request_firmware
};

----------------------------

Change this:

   case SAA7134_BOARD_KWORLD_DVBT_210:
       dev->dvb.frontend = dvb_attach(tda10046_attach, 
&kworld_dvb_t_210_config, &dev->i2c_adap);
       if (dev->dvb.frontend) {
           if (dvb_attach(tda827x_attach,dev->dvb.frontend,
                  kworld_dvb_t_210_config.tuner_address, &dev->i2c_adap,
                               &kw210_cfg) == NULL) {
               wprintk("no tda827x tuner found at addr: %02x\n",
                   kworld_dvb_t_210_config.tuner_address);
           }
       }
       break;

---------------------------------------------

However, I need you to explain something for me.

There is no difference if I use this:

   saa7134_set_gpio(dev, 22, 1);

or this:

   saa7134_set_gpio(dev, 21, 1);

I await your guidance, meanwhile I shall apply my
modification to enable the remote and ensure it
doesn't have any effect.

Many thanks to you both,

Regards,
Tim

Hi Hartmut,
OK, found some more spare time, but very, very frustrated!

1) Tried ubuntu 7.04, 7.10, 8.04

For the Medion8800 Quad and CTX948 also showing this issue, needs to tune analog first to have good recepton on DVB-T, they are a little weaker on analog than other cards, but after that on DVB-T, they are as good than known good others.

Hi Hartmut and Hermann,

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled tuner
chip...
This means that your initial config file is ok...

Answer - Yes, the non-working remote (and constant unknown key messages) is all that is
wrong with the pinnacle 310i.
I tested it for your new tda8290 tda8275 patches - didn't I send you the results?
It works fine!

b) Does this mean that in case 4, all other channels are found?

Answer - In linux, if start dvb-t first, never scans SBS
- yes all other channels are viewable/scannable.

c) Case 5: This finds everything?

Answer - In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS
- yes all channels are viewable/scannable.

d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.

Answer - the same answer applies as for b) and c)

e) Just to be sure: did you clarify the open point with .antenna_switch (i think so)

Answer - yes that was me being over-enthusiastic - made no difference as you pointed out.

OK, this modification has achieved, I think success. I can now view/scan all channels
in analog tv or dvb-t in either order.
That is, I now don't have to start analog tv first, before dvb-t will start.

In saa7134- cards.c - no change.

Hi Hartmut,

I was wrong:

->There is no difference if I use this:

-> saa7134_set_gpio(dev, 22, 1);

->or this:

-> saa7134_set_gpio(dev, 21, 1);

This is wrong.
It only works at all when it is this: saa7134_set_gpio(dev, 22, 1);

With this: saa7134_set_gpio(dev, 21, 1); it does not scan anything at all.

I proved this out by modifying the source, rebuild v4l-dvb, and then instead of rebooting, I power-cycled each time.

There are 2 problems here:
1) With no modification, I must switch to analog tv before I can switch to dvb-t.
If I am using Kaffeine, and then wish to use Me-tv, I must view
analog tv
in between.

2) With no modification, dvb-t will not scan SBS unless analog tv viewed first.

With this modification, both problems vanish.

I have not yet tested radio.

Regards,
Tim

Hi Hartmut,

OK, tried to test radio with gradio, can't get any frequency to lock.

Now, switching to radio then causes analog tv to have a very weak signal
- only 1 channel will scan with very noisy picture.

Then need to power-cycle to revert to good system.

Hi Hartmut,
OK, found some more spare time, but very, very frustrated!

1) Tried ubuntu 7.04, 7.10, 8.04
Tried with just modules that exist in kernel (no v4l-dvb)
Tried v4l-dvb from June 2007 and tried current v4l-dvb
Tried with/without Hartmut patch - changeset 7376 49ba58715fe0
Tried with .gpio_config = TDA10046_GP11_I, or .gpio_config
= TDA10046_GP01_I,
Tried using configs in saa7134-dvb.c matching tiger, tiger_s,
pinnacle 310i, twinhan 3056

2) I have these saa7134 cards:
- pinnacle 310i
- kworld 210

This cx88 card:
- dvico DVB-T Pro hybrid (analog tv not work)

- problem only occurs with kworld 210 in linux (works fine in
WinXP)

Quoted 11 lines

3) In WinXP, all channels, both analog tv and dvb-t found

4) In linux, if start dvb-t first, never scans SBS - dmesg1

5) In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS - dmesg2

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled tuner
chip...
This means that your initial config file is ok...
b) Does this mean that in case 4, all other channels are found?
c) Case 5: This finds everything?
d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.
e) Just to be sure: did you clarify the open point with .antenna_switch
(i think so)
f) the kernel logs are as expected.

6) Herman mentioned something called a "mode-switch" in the archives, but not any description.

Quoted 7 lines

I guess he meant the switching between analog, radio and dvb-t. This is the
GPIO handling and card depending.

Tim must have it from when I mentioned the special case of card=87 and 94.

Quoted 12 lines

Quoted 6 lines

I tried to find some data sheets for tda8275 tda8290 but only found the publicity pdf file from Phillips,
so at least I can see they go together, so I presume this "mode-switch" is coded into those modules.
But those modules work for all other cards, so now I'm lost again.

Quoted 6 lines

What else should I try?

Quoted 12 lines

If my assumptions above are wrong, there is one other chance:
Recently i saw another card that does the (unusual) mode switching like card 87. So to be sure, you might try to force this card type (be aware of the antenna inputs, if in doubt, try both.

Best regards
Hartmut

For the Medion8800 Quad and CTX948 also showing this issue, needs to tune analog first to have good recepton on DVB-T, they are a little weaker on analog than other cards, but after that on DVB-T, they are as good than known good others.

Cheers,
Hermann

Hi Hartmut and Hermann,

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled tuner
chip...
This means that your initial config file is ok...

Answer - Yes, the non-working remote (and constant unknown key messages) is all that is
wrong with the pinnacle 310i.
I tested it for your new tda8290 tda8275 patches - didn't I send you the results?
It works fine!

b) Does this mean that in case 4, all other channels are found?

Answer - In linux, if start dvb-t first, never scans SBS
- yes all other channels are viewable/scannable.

c) Case 5: This finds everything?

Answer - In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS
- yes all channels are viewable/scannable.

d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.

Answer - the same answer applies as for b) and c)

e) Just to be sure: did you clarify the open point with .antenna_switch (i think so)

Answer - yes that was me being over-enthusiastic - made no difference as you pointed out.

OK, this modification has achieved, I think success. I can now view/scan all channels
in analog tv or dvb-t in either order.
That is, I now don't have to start analog tv first, before dvb-t will start.

In saa7134- cards.c - no change.

In saa7134-dvb.c:

Remove this:
------------------------------------

static struct tda1004x_config kworld_dvb_t_210_config = {
   .demod_address = 0x08,
   .invert        = 1,

   .tuner_address = 0x61,
   .antenna_switch= 1,
   .request_firmware = philips_tda1004x_request_firmware
};

------------------------------

Add this:

------------------------------
static int kw210_tuner_init(struct dvb_frontend *fe)

{
   struct saa7134_dev *dev = fe->dvb->priv;
   philips_tda827x_tuner_init(fe);
   /* route TDA8275a AGC input to the channel decoder */
   saa7134_set_gpio(dev, 22, 1);
   return 0;

static int kw210_tuner_sleep(struct dvb_frontend *fe)

{
   struct saa7134_dev *dev = fe->dvb->priv;
   /* route TDA8275a AGC input to the analog IF chip*/
   saa7134_set_gpio(dev, 22, 0);
   philips_tda827x_tuner_sleep(fe);
   return 0;
}

static struct tda827x_config kw210_cfg = {
   .tuner_callback = saa7134_tuner_callback,
   .init = kw210_tuner_init,
   .sleep = kw210_tuner_sleep,

   .tuner_address = 0x61,
   .request_firmware = philips_tda1004x_request_firmware
};

----------------------------

Change this:

   case SAA7134_BOARD_KWORLD_DVBT_210:
       dev->dvb.frontend = dvb_attach(tda10046_attach, 
&kworld_dvb_t_210_config, &dev->i2c_adap);
       if (dev->dvb.frontend) {
           if (dvb_attach(tda827x_attach,dev->dvb.frontend,
                  kworld_dvb_t_210_config.tuner_address, &dev->i2c_adap,
                               &kw210_cfg) == NULL) {
               wprintk("no tda827x tuner found at addr: %02x\n",
                   kworld_dvb_t_210_config.tuner_address);
           }
       }
       break;

---------------------------------------------

However, I need you to explain something for me.

There is no difference if I use this:

   saa7134_set_gpio(dev, 22, 1);

or this:

   saa7134_set_gpio(dev, 21, 1);

Quoted 12 lines

I await your guidance, meanwhile I shall apply my
modification to enable the remote and ensure it
doesn't have any effect.

Many thanks to you both,

Regards,
Tim

Again progress, excellent!
I think we will need one further interation. If i go through your changes and comments, i come to the opinion that we will get the same with less changes. But if i understand this right, its astonishing that your
card worked a bit. But let me go through your last patch again tomorrow - i am too tired now.

Hi Hartmut,

I was wrong:

->There is no difference if I use this:

-> saa7134_set_gpio(dev, 22, 1);

->or this:

-> saa7134_set_gpio(dev, 21, 1);

This is wrong.
It only works at all when it is this: saa7134_set_gpio(dev, 22, 1);

With this: saa7134_set_gpio(dev, 21, 1); it does not scan anything at all.

I proved this out by modifying the source, rebuild v4l-dvb, and then instead of rebooting, I power-cycled each time.

There are 2 problems here:
1) With no modification, I must switch to analog tv before I can switch to dvb-t.
If I am using Kaffeine, and then wish to use Me-tv, I must view
analog tv
in between.

2) With no modification, dvb-t will not scan SBS unless analog tv viewed first.

With this modification, both problems vanish.

I have not yet tested radio.

Hi Hartmut,

OK, tried to test radio with gradio, can't get any frequency to lock.

Now, switching to radio then causes analog tv to have a very weak signal
- only 1 channel will scan with very noisy picture.

Then need to power-cycle to revert to good system.

Hi Hartmut,
OK, I'll send you this info that I think I have worked out so far:

.gpiomask = 1 << 21, is equivalent to:
GPIO 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 gpiomask 0x00200000 = 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Seems to be:
GPIO22 = 1 for DVB-T
GPIO22 = 0 for analog-tv

What then for radio? Perhaps GPIO21 is radio?
Try this:
.gpiomask = 0 << 22
GPIO 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 gpiomask 0x00000000 = 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Should give start with analog-tv = on; radio =off
.gpio = 0x00200000, for radio on (GPIO21 = 1)
Result:
No radio, but dvb-t, analog-tv is ok.

My guess is that GPIO22 = 1 (dvb-t); = 0 (analog-tv, default) GPIO21 = 0 or 1 for radio
But you would have to switch antenna from TV to radio via demux first? I can't see where/how to do that.

It seems as if the gpiomask should be applied to GPIO22? Then how to start radio?

Tim

Hi Hartmut,
OK, found some more spare time, but very, very frustrated!

1) Tried ubuntu 7.04, 7.10, 8.04
Tried with just modules that exist in kernel (no v4l-dvb)
Tried v4l-dvb from June 2007 and tried current v4l-dvb
Tried with/without Hartmut patch - changeset 7376 49ba58715fe0
Tried with .gpio_config = TDA10046_GP11_I, or .gpio_config
= TDA10046_GP01_I,
Tried using configs in saa7134-dvb.c matching tiger, tiger_s,
pinnacle 310i, twinhan 3056

# Australia / Perth (Roleystone transmitter)
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval

2) I have these saa7134 cards:
- pinnacle 310i
- kworld 210

This cx88 card:
- dvico DVB-T Pro hybrid (analog tv not work)

- problem only occurs with kworld 210 in linux (works fine in
WinXP)

Quoted 11 lines

3) In WinXP, all channels, both analog tv and dvb-t found

4) In linux, if start dvb-t first, never scans SBS - dmesg1

5) In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS - dmesg2

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled tuner
chip...
This means that your initial config file is ok...
b) Does this mean that in case 4, all other channels are found?
c) Case 5: This finds everything?
d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.
e) Just to be sure: did you clarify the open point with .antenna_switch
(i think so)
f) the kernel logs are as expected.

6) Herman mentioned something called a "mode-switch" in the archives, but not any description.

Quoted 7 lines

I guess he meant the switching between analog, radio and dvb-t. This is the
GPIO handling and card depending.

Tim must have it from when I mentioned the special case of card=87 and 94.

Quoted 12 lines

Quoted 6 lines

I tried to find some data sheets for tda8275 tda8290 but only found the publicity pdf file from Phillips,
so at least I can see they go together, so I presume this "mode-switch" is coded into those modules.
But those modules work for all other cards, so now I'm lost again.

Quoted 6 lines

What else should I try?

Quoted 12 lines

If my assumptions above are wrong, there is one other chance:
Recently i saw another card that does the (unusual) mode switching like card 87. So to be sure, you might try to force this card type (be aware of the antenna inputs, if in doubt, try both.

Best regards
Hartmut

For the Medion8800 Quad and CTX948 also showing this issue, needs to tune analog first to have good recepton on DVB-T, they are a little weaker on analog than other cards, but after that on DVB-T, they are as good than known good others.

Cheers,
Hermann

Hi Hartmut and Hermann,

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled tuner
chip...
This means that your initial config file is ok...

Answer - Yes, the non-working remote (and constant unknown key messages) is all that is
wrong with the pinnacle 310i.
I tested it for your new tda8290 tda8275 patches - didn't I send you the results?
It works fine!

b) Does this mean that in case 4, all other channels are found?

Answer - In linux, if start dvb-t first, never scans SBS
- yes all other channels are viewable/scannable.

c) Case 5: This finds everything?

Answer - In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS
- yes all channels are viewable/scannable.

d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.

Answer - the same answer applies as for b) and c)

e) Just to be sure: did you clarify the open point with .antenna_switch (i think so)

Answer - yes that was me being over-enthusiastic - made no difference as you pointed out.

OK, this modification has achieved, I think success. I can now view/scan all channels
in analog tv or dvb-t in either order.
That is, I now don't have to start analog tv first, before dvb-t will start.

In saa7134- cards.c - no change.

In saa7134-dvb.c:

Remove this:
------------------------------------

static struct tda1004x_config kworld_dvb_t_210_config = {
   .demod_address = 0x08,

   .tuner_address = 0x61,
   .antenna_switch= 1,
   .request_firmware = philips_tda1004x_request_firmware
};

------------------------------

Add this:

------------------------------
static int kw210_tuner_init(struct dvb_frontend *fe)

{
   struct saa7134_dev *dev = fe->dvb->priv;
   philips_tda827x_tuner_init(fe);

   saa7134_set_gpio(dev, 22, 0);
   philips_tda827x_tuner_sleep(fe);
   return 0;
}

static struct tda827x_config kw210_cfg = {
   .tuner_callback = saa7134_tuner_callback,
   .init = kw210_tuner_init,
   .sleep = kw210_tuner_sleep,
   .config = 0
};

   .tuner_address = 0x61,
   .request_firmware = philips_tda1004x_request_firmware
};

----------------------------

Change this:

   case SAA7134_BOARD_KWORLD_DVBT_210:
       dev->dvb.frontend = dvb_attach(tda10046_attach, 
&kworld_dvb_t_210_config, &dev->i2c_adap);
       if (dev->dvb.frontend) {
           if (dvb_attach(tda827x_attach,dev->dvb.frontend,
                  kworld_dvb_t_210_config.tuner_address, &dev->i2c_adap,
                               &kw210_cfg) == NULL) {
               wprintk("no tda827x tuner found at addr: %02x\n",
                   kworld_dvb_t_210_config.tuner_address);
           }
       }
       break;

---------------------------------------------

However, I need you to explain something for me.

There is no difference if I use this:

   saa7134_set_gpio(dev, 22, 1);

or this:

   saa7134_set_gpio(dev, 21, 1);

Quoted 12 lines

I await your guidance, meanwhile I shall apply my
modification to enable the remote and ensure it
doesn't have any effect.

Many thanks to you both,

Regards,
Tim

Again progress, excellent!
I think we will need one further interation. If i go through your changes and comments, i come to the opinion that we will get the same with less changes. But if i understand this right, its astonishing that your
card worked a bit. But let me go through your last patch again tomorrow - i am too tired now.

Hi Hartmut,

I was wrong:

->There is no difference if I use this:

-> saa7134_set_gpio(dev, 22, 1);

->or this:

-> saa7134_set_gpio(dev, 21, 1);

This is wrong.
It only works at all when it is this: saa7134_set_gpio(dev, 22, 1);

With this: saa7134_set_gpio(dev, 21, 1); it does not scan anything at all.

I proved this out by modifying the source, rebuild v4l-dvb, and then instead of rebooting, I power-cycled each time.

There are 2 problems here:
1) With no modification, I must switch to analog tv before I can switch to dvb-t.
If I am using Kaffeine, and then wish to use Me-tv, I must view
analog tv
in between.

2) With no modification, dvb-t will not scan SBS unless analog tv viewed first.

With this modification, both problems vanish.

I have not yet tested radio.

Hi Hartmut,

OK, tried to test radio with gradio, can't get any frequency to lock.

Now, switching to radio then causes analog tv to have a very weak signal
- only 1 channel will scan with very noisy picture.

Then need to power-cycle to revert to good system.

GPIO 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 gpiomask 0x00000000 = 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Should give start with analog-tv = on; radio =off
.gpio = 0x00200000, for radio on (GPIO21 = 1)
Result:
No radio, but dvb-t, analog-tv is ok.

My guess is that GPIO22 = 1 (dvb-t); = 0 (analog-tv, default) GPIO21 = 0 or 1 for radio
But you would have to switch antenna from TV to radio via demux first? I can't see where/how to do that.

It seems as if the gpiomask should be applied to GPIO22? Then how to start radio?

Tim

Something I don't understand.

This card: KWORLD VS-DVBT210RF

Chips:
SAA7131E - video decoder
TDA10046A - DVB-T decoder
KS007 - remote controller
HC4052 - analog demux
24C02BN - eeprom
NXP 8275A - tuner

Now, other cards have something such as mt352 as an IF demod I was under the impression that the 8275 went with an 8290 IF demod, but there is no demod chip on this card.

How does that work?

The tuner on the Pinnacle 310i is under a metal shield, so I can't actually see it.

I'm just getting more confused - there has to be something for the IF stage!

Hi Hartmut,
OK, found some more spare time, but very, very frustrated!

1) Tried ubuntu 7.04, 7.10, 8.04
Tried with just modules that exist in kernel (no v4l-dvb)
Tried v4l-dvb from June 2007 and tried current v4l-dvb Tried with/without Hartmut patch - changeset 7376

Tried with .gpio_config = TDA10046_GP11_I, or
.gpio_config = TDA10046_GP01_I,
Tried using configs in saa7134-dvb.c matching tiger,
tiger_s, pinnacle 310i, twinhan 3056

2) I have these saa7134 cards:
- pinnacle 310i
- kworld 210

This cx88 card:
- dvico DVB-T Pro hybrid (analog tv not work)

- problem only occurs with kworld 210 in linux (works fine
in WinXP)

3) In WinXP, all channels, both analog tv and dvb-t found

4) In linux, if start dvb-t first, never scans SBS - dmesg1

5) In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS - dmesg2

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled
tuner chip...
This means that your initial config file is ok...
b) Does this mean that in case 4, all other channels are found?
c) Case 5: This finds everything?
d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.
e) Just to be sure: did you clarify the open point with .antenna_switch
(i think so)
f) the kernel logs are as expected.

6) Herman mentioned something called a "mode-switch" in the archives, but not any description.

I guess he meant the switching between analog, radio and dvb-t. This is the
GPIO handling and card depending.

Tim must have it from when I mentioned the special case of card=87 and
94.

Quoted 10 lines

I tried to find some data sheets for tda8275 tda8290 but only found the publicity pdf file from Phillips,
so at least I can see they go together, so I presume this "mode-switch" is coded into those modules.
But those modules work for all other cards, so now I'm lost again.

What else should I try?

If my assumptions above are wrong, there is one other chance:
Recently i saw another card that does the (unusual) mode switching
like card 87. So to be sure, you might try to force this card type (be
aware of the antenna inputs, if in doubt, try both.

For the Medion8800 Quad and CTX948 also showing this issue, needs to
tune analog first to have good recepton on DVB-T, they are a little
weaker on analog than other cards, but after that on DVB-T, they are as
good than known good others.

Hi Hartmut and Hermann,

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled
tuner chip...
This means that your initial config file is ok...

Answer - Yes, the non-working remote (and constant unknown key messages) is all that is
wrong with the pinnacle 310i.
I tested it for your new tda8290 tda8275 patches - didn't I send you the results?
It works fine!

b) Does this mean that in case 4, all other channels are found?

Answer - In linux, if start dvb-t first, never scans SBS
- yes all other channels are viewable/scannable.

c) Case 5: This finds everything?

Answer - In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS
- yes all channels are viewable/scannable.

d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.

Answer - the same answer applies as for b) and c)

e) Just to be sure: did you clarify the open point with .antenna_switch
(i think so)

Answer - yes that was me being over-enthusiastic - made no difference
as you pointed out.

OK, this modification has achieved, I think success. I can now view/scan all channels
in analog tv or dvb-t in either order.
That is, I now don't have to start analog tv first, before dvb-t will start.

In saa7134- cards.c - no change.

In saa7134-dvb.c:

Remove this:

           }
       }
       break;

---------------------------------------------

However, I need you to explain something for me.

There is no difference if I use this:

   saa7134_set_gpio(dev, 22, 1);

or this:

   saa7134_set_gpio(dev, 21, 1);

I await your guidance, meanwhile I shall apply my
modification to enable the remote and ensure it
doesn't have any effect.

Many thanks to you both,

Again progress, excellent!
I think we will need one further interation. If i go through your changes and comments, i come to the opinion that we will get the same
with less changes. But if i understand this right, its astonishing that your
card worked a bit. But let me go through your last patch again tomorrow -
i am too tired now.

Hi Hartmut,

I was wrong:

->There is no difference if I use this:

-> saa7134_set_gpio(dev, 22, 1);

->or this:

-> saa7134_set_gpio(dev, 21, 1);

This is wrong.
It only works at all when it is this: saa7134_set_gpio(dev, 22, 1);

With this: saa7134_set_gpio(dev, 21, 1); it does not scan
anything at all.

I proved this out by modifying the source, rebuild v4l-dvb, and then instead of rebooting, I power-cycled each time.

There are 2 problems here:
1) With no modification, I must switch to analog tv before I can switch to dvb-t.
If I am using Kaffeine, and then wish to use Me-tv, I must
view analog tv
in between.

2) With no modification, dvb-t will not scan SBS unless analog tv viewed first.

With this modification, both problems vanish.

I have not yet tested radio.

Hi Hartmut,

OK, tried to test radio with gradio, can't get any frequency to lock.

Now, switching to radio then causes analog tv to have a very weak signal - only 1 channel will scan with very noisy picture.

Then need to power-cycle to revert to good system.

Seems to be:
GPIO22 = 1 for DVB-T
GPIO22 = 0 for analog-tv

What then for radio? Perhaps GPIO21 is radio?
Try this:
.gpiomask = 0 << 22
GPIO 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 gpiomask 0x00000000 = 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Should give start with analog-tv = on; radio =off
.gpio = 0x00200000, for radio on (GPIO21 = 1)
Result:
No radio, but dvb-t, analog-tv is ok.

My guess is that GPIO22 = 1 (dvb-t); = 0 (analog-tv, default) GPIO21 = 0 or 1 for radio
But you would have to switch antenna from TV to radio via demux first? I can't see where/how to do that.

It seems as if the gpiomask should be applied to GPIO22? Then how to start radio?

Tim

Now, other cards have something such as mt352 as an IF demod I was under the impression that the 8275 went with an 8290 IF demod, but there is no demod chip on this card.

How does that work?

mt352 is a dvb-t channel decoder. But you are right, the tda8275(a) needs a tda8290 for analog tv. But this is integrated in the saa7131.

Right! its in the saa7131.

I think i know now how your card needs to be configured. Something that seems not to be really clear for you is the configuration of the so-called AGC (automatic gain control) of the tuner. This needs to be switched according to the function the tuner is used for:
analog TV -> FM Radio -> DVB-T.
This is done with the 4052 analog mux and requires 2 control bits -> the GPIOs.
GPIO 21 is used to switch between analog TV and FM radio. Typically GPIO21=0 -> analog TV, GPIO21=1 -> FM Radio.
In your case, GPIO22 is used to switch between DVB-T and analog while most cards
use GPIO1 of the tda10046 for this.

You should need to make chages only in saa7134-dvb, dvb_init()
- remove the old

    case SAA7134_BOARD_KWORLD_DVBT_210: (plus code)

-and add it to
case SAA7134_BOARD_FLYDVBT_HYBRID_CARDBUS:

That should do it (though we should add a .antenna switch to the configuration).

Hi Hartmut,
OK, found some more spare time, but very, very frustrated!

1) Tried ubuntu 7.04, 7.10, 8.04
Tried with just modules that exist in kernel (no v4l-dvb)
Tried v4l-dvb from June 2007 and tried current v4l-dvb Tried with/without Hartmut patch - changeset 7376
49ba58715fe0
Tried with .gpio_config = TDA10046_GP11_I, or
.gpio_config = TDA10046_GP01_I,
Tried using configs in saa7134-dvb.c matching tiger,
tiger_s, pinnacle 310i, twinhan 3056

2) I have these saa7134 cards:
- pinnacle 310i
- kworld 210

This cx88 card:
- dvico DVB-T Pro hybrid (analog tv not work)

- problem only occurs with kworld 210 in linux (works fine
in WinXP)

3) In WinXP, all channels, both analog tv and dvb-t found

4) In linux, if start dvb-t first, never scans SBS - dmesg1

5) In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS - dmesg2

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled
tuner chip...
This means that your initial config file is ok...
b) Does this mean that in case 4, all other channels are found?
c) Case 5: This finds everything?
d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.
e) Just to be sure: did you clarify the open point with .antenna_switch
(i think so)
f) the kernel logs are as expected.

6) Herman mentioned something called a "mode-switch" in the archives, but not any description.

I guess he meant the switching between analog, radio and dvb-t. This is the
GPIO handling and card depending.

Tim must have it from when I mentioned the special case of card=87 and
94.

Quoted 10 lines

I tried to find some data sheets for tda8275 tda8290 but only found the publicity pdf file from Phillips,
so at least I can see they go together, so I presume this "mode-switch" is coded into those modules.
But those modules work for all other cards, so now I'm lost again.

What else should I try?

If my assumptions above are wrong, there is one other chance:
Recently i saw another card that does the (unusual) mode switching
like card 87. So to be sure, you might try to force this card type (be
aware of the antenna inputs, if in doubt, try both.

For the Medion8800 Quad and CTX948 also showing this issue, needs to
tune analog first to have good recepton on DVB-T, they are a little
weaker on analog than other cards, but after that on DVB-T, they are as
good than known good others.

Hi Hartmut and Hermann,

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled
tuner chip...
This means that your initial config file is ok...

Answer - Yes, the non-working remote (and constant unknown key messages) is all that is
wrong with the pinnacle 310i.
I tested it for your new tda8290 tda8275 patches - didn't I send you the results?
It works fine!

b) Does this mean that in case 4, all other channels are found?

Answer - In linux, if start dvb-t first, never scans SBS
- yes all other channels are viewable/scannable.

c) Case 5: This finds everything?

Answer - In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS
- yes all channels are viewable/scannable.

d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.

Answer - the same answer applies as for b) and c)

e) Just to be sure: did you clarify the open point with .antenna_switch
(i think so)

Answer - yes that was me being over-enthusiastic - made no difference
as you pointed out.

OK, this modification has achieved, I think success. I can now view/scan all channels
in analog tv or dvb-t in either order.
That is, I now don't have to start analog tv first, before dvb-t will start.

In saa7134- cards.c - no change.

In saa7134-dvb.c:

Remove this:

       }
       break;

---------------------------------------------

However, I need you to explain something for me.

There is no difference if I use this:

or this:

   saa7134_set_gpio(dev, 21, 1);

I await your guidance, meanwhile I shall apply my

doesn't have any effect.

Many thanks to you both,

Again progress, excellent!
I think we will need one further interation. If i go through your changes and comments, i come to the opinion that we will get the same
with less changes. But if i understand this right, its astonishing that your
card worked a bit. But let me go through your last patch again tomorrow -
i am too tired now.

Hi Hartmut,

I was wrong:

->There is no difference if I use this:

-> saa7134_set_gpio(dev, 22, 1);

->or this:

-> saa7134_set_gpio(dev, 21, 1);

This is wrong.
It only works at all when it is this: saa7134_set_gpio(dev, 22, 1);

With this: saa7134_set_gpio(dev, 21, 1); it does not scan
anything at all.

I proved this out by modifying the source, rebuild v4l-dvb, and then instead of rebooting, I power-cycled each time.

There are 2 problems here:
1) With no modification, I must switch to analog tv before I can switch to dvb-t.
If I am using Kaffeine, and then wish to use Me-tv, I must
view analog tv
in between.

2) With no modification, dvb-t will not scan SBS unless analog tv viewed first.

With this modification, both problems vanish.

I have not yet tested radio.

Hi Hartmut,

OK, tried to test radio with gradio, can't get any frequency to lock.

Now, switching to radio then causes analog tv to have a very weak signal - only 1 channel will scan with very noisy picture.

Then need to power-cycle to revert to good system.

Seems to be:
GPIO22 = 1 for DVB-T
GPIO22 = 0 for analog-tv

What then for radio? Perhaps GPIO21 is radio?
Try this:
.gpiomask = 0 << 22
GPIO 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 gpiomask 0x00000000 = 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Should give start with analog-tv = on; radio =off
.gpio = 0x00200000, for radio on (GPIO21 = 1)
Result:
No radio, but dvb-t, analog-tv is ok.

My guess is that GPIO22 = 1 (dvb-t); = 0 (analog-tv, default) GPIO21 = 0 or 1 for radio
But you would have to switch antenna from TV to radio via demux first? I can't see where/how to do that.

It seems as if the gpiomask should be applied to GPIO22? Then how to start radio?

Tim

Now, other cards have something such as mt352 as an IF demod I was under the impression that the 8275 went with an 8290 IF demod, but there is no demod chip on this card.

How does that work?

mt352 is a dvb-t channel decoder. But you are right, the tda8275(a) needs a tda8290 for analog tv. But this is integrated in the saa7131.

I think i know now how your card needs to be configured. Something that seems not to be really clear for you is the configuration of the so-called AGC (automatic gain control) of the tuner. This needs to be switched according to the function the tuner is used for:
analog TV -> FM Radio -> DVB-T.
This is done with the 4052 analog mux and requires 2 control bits -> the GPIOs.
GPIO 21 is used to switch between analog TV and FM radio. Typically GPIO21=0 -> analog TV, GPIO21=1 -> FM Radio.
In your case, GPIO22 is used to switch between DVB-T and analog while most cards
use GPIO1 of the tda10046 for this.

You should need to make chages only in saa7134-dvb, dvb_init()
- remove the old

My problem is that this works:

   .gpio_config   = TDA10046_GP11_I,
but this doesn't:
   .gpio_config   = TDA10046_GP00_I,

And I was going to add this:

   .antenna_switch= 1,

to my struct.

I think i know now how your card needs to be configured. Something that seems not to be really clear for you is the configuration
of the so-called AGC (automatic gain control) of the tuner. This needs to be switched according to the function the tuner is used for:
analog TV -> FM Radio -> DVB-T.
This is done with the 4052 analog mux and requires 2 control bits -> the GPIOs.
GPIO 21 is used to switch between analog TV and FM radio. Typically GPIO21=0 -> analog TV, GPIO21=1 -> FM Radio.
In your case, GPIO22 is used to switch between DVB-T and analog while most cards
use GPIO1 of the tda10046 for this.

You should need to make chages only in saa7134-dvb, dvb_init()

Ok , the antenna_switch is clear. But the
.gpio_config makes no sense. The card either uses either GPIO22 or the tda10046 for mode switching but not both.
What happens if you use the "bad" gpio_config?
Please switch to tzap for testing. This command line program clearly reports the status of the channel decoder, including signal level.

I think i know now how your card needs to be configured. Something that seems not to be really clear for you is the configuration
of the so-called AGC (automatic gain control) of the tuner. This needs to be switched according to the function the tuner is used for:
analog TV -> FM Radio -> DVB-T.
This is done with the 4052 analog mux and requires 2 control bits -> the GPIOs.
GPIO 21 is used to switch between analog TV and FM radio. Typically GPIO21=0 -> analog TV, GPIO21=1 -> FM Radio.
In your case, GPIO22 is used to switch between DVB-T and analog while most cards
use GPIO1 of the tda10046 for this.

You should need to make chages only in saa7134-dvb, dvb_init()
- remove the old

    case SAA7134_BOARD_KWORLD_DVBT_210: (plus code)

-and add it to
case SAA7134_BOARD_FLYDVBT_HYBRID_CARDBUS:

That should do it (though we should add a .antenna switch to the configuration).

However, analog-tv fails to scan anything -> "no signal"

This is wrong. Although the channel decoder locks, the signal at its input is very low.

But this means: The analog -> dvb switch is the GPIO of the channel decoder
*not* GPIO22

so we can fix: we need .gpio_config = TDA10046_GP11_I

I think i know now how your card needs to be configured. Something that seems not to be really clear for you is the configuration
of the so-called AGC (automatic gain control) of the tuner. This needs to be switched according to the function the tuner is used for:
analog TV -> FM Radio -> DVB-T.
This is done with the 4052 analog mux and requires 2 control bits -> the GPIOs.
GPIO 21 is used to switch between analog TV and FM radio. Typically GPIO21=0 -> analog TV, GPIO21=1 -> FM Radio.
In your case, GPIO22 is used to switch between DVB-T and analog while most cards
use GPIO1 of the tda10046 for this.

You should need to make chages only in saa7134-dvb, dvb_init()
- remove the old

    case SAA7134_BOARD_KWORLD_DVBT_210: (plus code)

Quoted 9 lines

-and add it to
case SAA7134_BOARD_FLYDVBT_HYBRID_CARDBUS:

That should do it (though we should add a .antenna switch to the configuration).

However, analog-tv fails to scan anything -> "no signal"

This is wrong. Although the channel decoder locks, the signal at its input is very low.

But this means: The analog -> dvb switch is the GPIO of the channel decoder
*not* GPIO22

so we can fix: we need .gpio_config = TDA10046_GP11_I

If I put .antenna_switch = 1 or 2, in my struct, dvb-t fails to scan. I can't put antenna_switch in my struct, can I, as I am using gpio22? So I took it out, and in saa7134-cards.c, changed .radio to this:

I don't believe that this is right.
It is just a static signal and can't be anything else.

I still can't tune to a radio cahnnel.
I'm not sure how to switch to radio, I'm not even sure which gpio it's on.
I assume it's on gpio21, but I've tried various configs - none work.

Hi

- you are aware that you can't use analog and dvb simultanously?
- you are aware that after stopping a dvb application it takes about a second before the dvb driver releases the card and the analog tuner
can be used?
- did you mix up the antenna inputs?

- problem only occurs with kworld 210 in linux (works fine in WinXP)

3) In WinXP, all channels, both analog tv and dvb-t found

4) In linux, if start dvb-t first, never scans SBS - dmesg1

5) In linux, if start analog tv first, stop, then start dvb-t, scan finds SBS - dmesg2

a) The pinnacle 310i finds everything?
It has the same chipset, but an almost perfectly handled tuner chip... This means that your initial config file is ok...
b) Does this mean that in case 4, all other channels are found?
c) Case 5: This finds everything?
d) What happens if you use the scan data of the pinnacle card? Does it tune SBS? Does it just take more time to stabilize? This can be understood.
e) Just to be sure: did you clarify the open point with .antenna_switch (i think so)
f) the kernel logs are as expected.

6) Herman mentioned something called a "mode-switch" in the archives, but not any description.

I guess he meant the switching between analog, radio and dvb-t. This is the GPIO handling and card depending.

Tim must have it from when I mentioned the special case of card=87 and 94.

I tried to find some data sheets for tda8275 tda8290 but only found the publicity pdf file from Phillips,
so at least I can see they go together, so I presume this "mode-switch" is coded into those modules.
But those modules work for all other cards, so now I'm lost again.

What else should I try?

If my assumptions above are wrong, there is one other chance:
Recently i saw another card that does the (unusual) mode switching like card 87. So to be sure, you might try to force this card type (be aware of the antenna inputs, if in doubt, try both.

For the Medion8800 Quad and CTX948 also showing this issue, needs to tune analog first to have good recepton on DVB-T, they are a little weaker on analog than other cards, but after that on DVB-T, they are as good than known good others.

Hi Hartmut,
OK, found some more spare time, but very, very frustrated!

1) Tried ubuntu 7.04, 7.10, 8.04
Tried with just modules that exist in kernel (no v4l-dvb)
Tried v4l-dvb from June 2007 and tried current v4l-dvb
Tried with/without Hartmut patch - changeset 7376 49ba58715fe0
Tried with .gpio_config = TDA10046_GP11_I, or .gpio_config =
TDA10046_GP01_I,
Tried using configs in saa7134-dvb.c matching tiger, tiger_s,
pinnacle 310i, twinhan 3056

Is this problem still there with the recent v4l-dvb code? I found a problem with the GPIO initialization and fixed this in patch 49ba58715fe0 3 weeks ago (The gpiomask was not set until analog tuning occured).

argh, my DVB-T signal can not be split much, so I left that other machine with DVB-S, cable-tv and the empress almost untouched during the last weeks and without DVB-T.
