Hi Davin,
I have a question. How are loaded the base firmware into xc3028, in once or in a split ? It's importent for TM6010, the USB-Analyzer said that it load it in once and then send a quitting reqeuest. -----BEGIN PGP SIGNATURE-----

In most drivers, the xc3028 firmware gets broken down and sent in 64 byte chunks. The size of the chunks is controlled by the "max_len" field in the xc2028_ctrl structure.

Hi Darvin,

I see. I have set for test "max_len" to 3500 . So can send after main firmware wrote (3411 byte) a quitting request send (base firmware is 9144 byte). Is it true that the tuner output frequency and the demodulator input frequency equal is?

Thanks

It is highly unlikely that the tm6010 can do 3500 at a time. Try someting more reasonable like "32" or "64".

Yes, typically the IF out of the tuner should match the IF on the demodulator.

Hi Davin,

The way the original driver for tm6000/tm6010 does varies from firmware version to firmware version. That part of the driver works fine for both tm6000 and tm6010, with the devices I used here, with firmwares 1.e and 2.7. However, on tm6000, it sends the firmware on packages with up to 12 or 13 bytes, and it requires a delay before sending the next packet, otherwise the tm6000 hangs.

Another problem is that the firmware load may fail (due to the bad implementation of the i2c on tm6000/tm6010). So, the code should ideally check if the firmware were loaded, by reading the firmware version at the end. However, reading from i2c is very problematic, since it sometimes read from the wrong place. On the tests I did here, the original drivers weren't reading back the firmware version, probably due to this bug.

Cheers,
Mauro.

My hybrid-stick with tm6010 chip use a special request ( requests 0x32 + 0x33) for quitting i2c transfer. so it can write correct the firmware and can read tuner number and versions. Actually I tested next patch for sync between tuner and demodulator and I have data by scanning digital channels (one time), but other test dos not data. I've test firmware load 13, 64 and 3500 bytes and all works.

Someone once commented that there are some procedures to reset I2C bank on tm6010. Maybe that's the meaning for the requests to 0x32/0x33.

3500? That's weird! the maximum allowed size for URB control transfer is 80.
Quoted 7 lines
from xc3028 send max 3500 byte and then in i2c_xfer function it split to 80 byte.
for example
xc3028 --> 3500 byte --> quit (base firmware subaddresse 0x2a 3411 byte) tm6000_i2c_xfer --> 80 byte 80 byte .... 80 byte ---> quit

Quoted 7 lines

Well, the better is to limit the size at xc3028 level, just like the other drivers. I'm afraid that letting it pass 3500 bytes will cause kernel hangups on some drivers that aren't prepared for it.
Cheers,
Mauro.

Hi,

I found digital channel second time today, Last Saturday I found first time. But it has over hack demodulator.

Hi,

I have a problem with usb bulk transfer. After a while, as I scan digital channel (it found a few channel), it wrote this in the log:

Jan 26 21:58:35 linux-v5dy kernel: [  548.756585] tm6000: status != 0

I updated the tm6000_urb_received function so that I can read the Error code and it logged:

Jan 27 17:41:28 linux-v5dy kernel: [ 3121.892793] tm6000: status = 0xffffffb5

Can you help me? Who I can calculate urb size?

Cheers

Jan 27 17:41:28 linux-v5dy kernel: [ 3121.892793] tm6000: status = 0xffffffb5

Probablt it is this error:
#define EOVERFLOW 75 /* Value too large for defined data type */

It would be good to make it display the error as a signed int.

the tm6000-video error handler has some common causes for those status. In this particular case:

        case -EOVERFLOW:
                errmsg = "Babble (bad cable?)";
                break;

This looks the same kind of errors I was receiving during the development of the driver:
a large amount of frames are got broken, even if the device is programmed with the exact values used on the original driver. On my tests, changing the URB size were changing the position where such errors were occurring.

Take a look on tm6000-video:

        size = usb_maxpacket(dev->udev, pipe, usb_pipeout(pipe));

        if (size > dev->max_isoc_in)
                size = dev->max_isoc_in;

It depends on the alternate interface used. The driver should select an alternate interface that is capable of receiving the entire size of a message. Maybe the tm6000 driver is missing the code that selects this size. Take a look on em28xx-core, at em28xx_set_alternate() code for an example on how this should work.

The calculated size there assumes that each pixel has 16 bits, and has some magic that were experimentally tested on that device.

Cheers,
Mauro.

I know why it's going to overflow. It's not usb pipe calculating, it's numbers of feeds that it's used. But then I cannot use more than one filter! It's bad!!
