piCore and Wolfson Audio Card

[bmarkus]

piCore-6.0alpha510.tar uploaded to http://tinycorelinux.net/6.x/armv6/test_releases/ and alsa modules updated with arizona mfd modules.  Hopefully it works now.

Thanks for the try, but I'm afraid that the wolfson card is not supported in the 3.17.2 kernel. Now I could load the arizona-spi but instead the snd-soc-wm5102 and snd-soc-rpi-wsp are missing


In modules.dep for 3.17.1 I find:
kernel/sound/soc/codecs/snd-soc-wm5102.ko
and
kernel/sound/soc/bcm/snd-soc-rpi-wsp.ko

But in the new 3.17.2 I can't find
snd-soc-wm5102.ko
snd-soc-rpi-wsp.ko

[bmarkus]

Thanks. It looks better at least. I will check missing modules, stay tuned.

Hi Bela

I think what happened is.
The pull request for support of the wolfson card was pulled into 3.17.1, but when they updated to 3.17.2 they decided not to pull in the wolfson support (or they forgot it) https://github.com/raspberrypi/linux/pull/705 .
Anyway I have asked at their github if it is included in 3.17.2 - but I suspect it is not included in the most recent version.

So you should not waste too much time on this for the time being

On the other hand most of the Wolfsson modules are in 3.17.2 and not removed. Anyhow Wolfson is not my fovirite hw vendor

[sbp]

I completely agree.
I think they produced a good audio card, however, because of their very poor software support it is of no use for most people.
So I would advice to find an alternative audio card, which by the way are coming from many different vendors.

So lets wait until the wolfson card is properly supported in the kernel.

[bmarkus]

You can open a ticket at https://github.com/raspberrypi/linux/issues and ask the status and whether somene got it already working. Also the rafberrip forum may help.

If you can provide proper config parameters I will apply them in the kernel, otherwise keep actual one which looks ok in general and I do not spend time to investigate the Wolfson mess.

Hi Bela

I got a response from the guys at Wolfson. In short the support for the wolfson card is not included in the most recent 3.17 version.

Code: [Select]

Hi, We haven't pushed this change in to the 3.17 kernel yet. The plan was to get this in to the 3.12 kernel which is what this pull
request is for and then we would start to look at the issue in 3.17 and forward porting this driver. There will be some of our code in the
3.17 kernel as this will have been picked up from the mainline kernel.

So maybe in the future this card will be supported, but at the time most users have moved on to a B+ or other small ARMs computers.

Hi Steen

thanks fo the info. I do not understand how B+ is related to the kernel but never mind. It is not there. I will disable it in the config, recompile the final 3.17.2 kernel for piCore 6.0 When Wolffson will be really supported we can decide how to manage it.

Regards... Bela

I think that you will find that there is nothing to disable as it is not available in the present config file. However, if you are reusing your config file from 3.17.1 than probably there will be some leftovers.

the final 3.17.2 kernel for piCore 6.0 When Wolffson will be really supported we can decide how to manage it.

Thats a good plan

[bmarkus]

I have used 3.17.1 config for 3.17.2 with oldconfig so it is there with many modules including arizona modules used by wolfsson modules....

[bmarkus]

3.17.2 rebuilt, Wolfsson/Arizona dropped. It is the final, no more kernel change. Will upload soon.

Hi... Good work!

Will 3.17.2 then be the kernel, for next release (piCore 6) ?

Yes
