Hi Manuel,
sorry for my continous s_p_a_m but i'm ignorant and i need a lot of support...

what currently i have:
a (sometimes) booting 2.6.26-rc8_edosk7760-00210-g35534ad-dirty kernel on a edosk_sh7760 board, with compiled-in:
SCIF console
smc eth91x support
i2c-sh7760
SoC sound support for sh7760 (NOT AC97)

what currently i miss:

. enabling " kernel modules versioning support" results in unbootable kernel
. enabling features as <M> results in unloadable modules: (insmod: couldn't find the kernel version the module was compiled for)
. loading smc91c96 driver fails at probe()
. alsa answer is "no soundcards found"
. every kernel option i enable often results in an unbootable kernel: /dev/i2c support; sh7760_AC97; alsa debug, scsi support (needed by usb mass storage): every of these i try to enable results in a kernel with no console output.

. i need to communicate (via i2c and i2S) to a wm8731 codec (on my custom board) ... i imagine i have to write a driver or something like to connect the codec and the sh sound interface. where to start?

Do you have some suggestions? my kernel seems very very delicate..... i attach my .config and my edosk7760/setup.c

thanks ,
Luca Santini

Hi Manuel,
sorry for my continous s_p_a_m but i'm ignorant and i need a lot of support...
what currently i have:
a (sometimes) booting 2.6.26-rc8_edosk7760-00210-g35534ad-dirty kernel on a edosk_sh7760 board, with compiled-in:
SCIF console
smc eth91x support
i2c-sh7760
SoC sound support for sh7760 (NOT AC97)

Quoted 4 lines

what currently i miss:
. enabling " kernel modules versioning support" results in unbootable kernel

That seems strange.. (There are other features which result in ubootable kernels, notably every cache mode other than the default "write-back").

Quoted 2 lines

. enabling features as <M> results in unloadable modules: (insmod: couldn't find the kernel version the module was compiled for)

modules installed into wrong directory? incorrect modules in rootfs?

. loading smc91c96 driver fails at probe()

Check MMIO area (chip is at 0x02000000 - 0x0200001f according to the ESDOK7760 manual available from renesas website if you didn't change any of the DIP switches on the board), and correct IRQ (9 if I interpret the schematics correctly)

Also, you need to edit drivers/net/smc91x.h and add an entry for your board to the jungle of ifdefs in there.
I.e. like this:

. alsa answer is "no soundcards found"

That's expected; you need to write ASoC "machine" code (that is, code which knows which codec and audio unit to use). Use the "sh7760-ac97.c" file as a template; replace the "ac97_dai" with something appropriate for the wm8731, and don't forget to change IPSELR to enable the I2S pins.

Quoted 4 lines

/dev/i2c support; sh7760_AC97; alsa debug, scsi support (needed by usb mass storage): every of these i try to enable results in a kernel with no console output.

Do you get any output with early_printk and sh_bios enabled?

Quoted 3 lines

. i need to communicate (via i2c and i2S) to a wm8731 codec (on my custom board) ... i imagine i have to write a driver or something like to connect the codec and the sh sound interface. where to start?

Quoted 2 lines

Do you have some suggestions? my kernel seems very very delicate..... i attach my .config and my edosk7760/setup.c

Could you please post a complete patch of your edosk7760 against vanilla-2.6.26?
What toolchain are you using?

I.e. like this:

This isn't necessary anymore, you are able to specificy everything you need through the platform data these days (this is true for smc91x as well as smc911x). So you can reduce the following:

to:

static struct smc91x_platdata smc91x_info = {

And then pass that in under the platform device. We already do that today for migor, se7722, etc.

That seems strange.. (There are other features which result in ubootable kernels, notably every cache mode other than the default "write-back").

cache mode is "write-back"
and this option isn't the only that makes the kernel unbootable...

...

In this way the LAN IC, which has a default base address of H’00300, will be accessed when the micon addresses H’0200 0000 to H’0200 003F.

so what are the right SMC_ADDRESS_START and SMC_ADDRESS_END addresses i have to write in this structure?

Could you please post a complete patch of your edosk7760 against vanilla-2.6.26?
This is a dirty patch for edosk7760 with something wrong in smc91x support (wrong addresses?)

yup. see above and below.

What toolchain are you using?
sh4-linux-gcc (GCC) 3.4.5 20060103 (3.4.5-10.1a) from MPC site

Should be fine.

remove SMC_IO_OFFSET and networking should work.

. loading smc91c96 driver fails at probe()
Check MMIO area (chip is at 0x02000000 - 0x0200001f according to the ESDOK7760 manual available from renesas website if you didn't change any of
the DIP switches on the board), and correct IRQ (9 if I interpret the schematics correctly)
Going over the schematics again:
this is a 91c96: you should add a "smc91x-attrib" mem resource. However I don't know which address to set it to; please check the NIC's manual. i.e.

Quoted 11 lines

struct resource smc91x_res[] = {
	...
	[1] = {
		.name = "smc91x-attrib",
		.start = ???,
		.endd = ???,
		.flags = IORESOURCE_MEM,
	},
	...
};

i can't imagine where to find the addresses, i searched in edosk7760 and smc91c96 manuals; others implementations that use this NIC ... someone knows? it's really necessary?

currently i have:

#define SMC_IOADDR 0xA2000000

static struct resource smc91x_res[] = {
[0] = {
.start = SMC_IOADDR,
.end = SMC_IOADDR + 0x1f,
.flags = IORESOURCE_MEM,
},
[1] = {
.start = ETHERNET_IRQ,
.end = ETHERNET_IRQ,
.flags = IORESOURCE_IRQ,
},

		[2] = {
		.name = "smc91x-attrib",
		.start  = SMC_IOADDR + 0x02000000,
		.end    = SMC_IOADDR + 0x03ffffff,
		.flags = IORESOURCE_MEM,
		},

};

It's going to be dependent on your board, so if it's not mentioned in your board documentation, then you need to contact your board vendor (obviously RTE in this case). On the other hand, you may also want to see what the MPC Data folks have done for this platform. Whatever it maps out to on other platforms is not going to be of any use to you.
