get usb sound support in varkey's rootfs

I am running varkey's rootfs on my pogoplug b04 (http://forum.doozan.com/read.php?3,6336,6371#msg-6371)

I want to use my usb soundcard so I can use pogoplug as audio streamer. But the usb sound module is not loaded in kernel. I did some googling and tried with following commands

downloaded source; apt-get install linux-source-2.6.32
make menuconfig
put an M in front of ALSA usb Soundcard
make modules
make modules_install

but it's not same kernel it's all placed in other directory. modules don't get loaded. Anyone knows how I can add these modules to the same kernel version as in the rootfs on my stick?

thanks.

mk2k,

Since you're running the Arch kernel on NAND, the modules that are actually loaded are Arch's (in /lib/modules/2.6.31.6_SMP_820/kernel/). So if you can find that module in your Arch rootfs, just copy it over to the appropriate directory in your Debian rootfs. Look back to my PogoPro Debian rootfs manual installation for examples in step 4,5,6 :
http://forum.doozan.com/read.php?3,6336

If you need to compile this module, then compile it in Arch first, and then copy it over.

bodhi, thanks for your suggestion. I copied over the modules, but got an error,so I also need the ARCH linux source, since I downloaded the debian source which is wrong. I get wrong module version error after doing a modprobe.
The correct source can be found here I think; http://download.pogoplug.com/opensource/pro/pogopro-linux-2.6.31.6-r2.tar.bz2
I am going to try with this source and see if that works out. thanks. i'll keep you posted

now i receive this error when running make:

/bin/sh/arm-none-linux-gnueabi-gcc not found

GOD, WHY ARE YOU DOING THIS TO ME???

Calm down! if you've found the modules in Arch rootfs, they should work. What kind of errors did you get? modprobe ? post the steps you did, and the errors you got, someone might have done the same and can give some hints.

Bodhi,

I downloaded the source, http://download.pogoplug.com/opensource/pro/pogopro-linux-2.6.31.6-r2.tar.bz2
exctracted it.

Ran make menuconfig

selected the usb sound card as module. Now trying to compile using make modules

then the error appears : /bin/sh/arm-none-linux-gnueabi-gcc command not found

didn't got that error when compling with the other linux source (the wrong version I used before)

I wouldn't recommend you to compile the modules your own because you need some experience how to do this. It is not so easy to compile modules which fit to the kernel. You need the right source files (from WarheadsSE git) and right configuration file (I don't know where to get it for the older kernel).

There are several problems with the ALARM kernel which can not be resolved even with the latest version! The drivers are available in the kernel but just don't work!

1. Support of several FTDI2Serial interfaces
2. PCSC card readers
3. USB sound cards

You could use another kernel: http://pogoplug.cwsurf.de/forum/viewtopic.php?f=5&t=98&start=0 (download links in 2nd post) either in save way booting it from SATA hard disk or on the more risky way to flash it to NAND. Please take the right kernel for your device. This kernel solves at least the three problems mentioned above.

The process to get the new kernel on the device can be fould in the ALARM kernel update thread:http://archlinuxarm.org/forum/viewtopic.php?f=55&t=2453. Just that it is a different kernel.

@mk2k,

What shv said. You might have given up too soon about the seting up Arch modules.

shv, thanks for your sugesstion. how can i boot your kernel version from usb ?
I already tried to put it on a stick but it didn't boot. yellow led kept blinking.

i dont want to overwrite the nand flash since i dont have console access to my pogoplug if something goes terribly schlecht, bin ich verdammt :)

the varkey works fine. any steps on how to get your files which can be found on the Deutsche sprache webseite ;-)

any guide available on how I can get the shv kernel working on my pogo. i have version b04 oxnas based.

You can take the same commands from the ALARM kernel updater package (http://archlinuxarm.org/forum/viewtopic.php?f=55&t=2453) but use my kernel instead. You might need to install the mtd-utils package to flash the right uImage to the flash. Just unpack the archive in your root folder. For B04 you must flash the NonPCI uImage.P21. You don't need to copy or move the old kernel modules to a different location because the new kernal has a different name and module path.

Please check if the following commands are the same as contained in update-kernel.sh! If anything is wrong you will brick your Pogoplug!

flash_erase /dev/mtd1 0x500000 20
nandwrite -p -s 0x500000 /dev/mtd1 /uImage_2.6.31.14_...P21

/etc/modules

mii
gmac
oxnas-led
leds-gpio-ox820-pogoplug3

/etc/rc.local

# turn on LED
/sbin/proled green

Good luck!
-shv

shv thanks. sorry, but you say: update-kernel.sh should contain the same commands. Just to be sure, is this script already anywhere on my pogoplug ? or do i need to change update-kernel.sh to match the commands you described?
the uimage i need flash is that in your download package as well or do i need to download that somewhere else. i have to make sure i have the correct files, since i dont want to brick the pogoplug.

thanks.

The file update-kernel.sh is part of the ALARM kernel update package. You should use the flashing commands after you made sure that they are the same as in update-kernel.sh script. You should use the uImage which is contained in my kernal package.

shv, okay thanks i need to download the archlinux updater pakage as well from this site: http://archlinuxarm.org/forum/viewtopic.php?f=55&t=2453. but flash your nopci.p21 from your package on my b04

what's the difference between the package on german site 2nd post and 8th post. i have downloaden yours from 8th post you say it contains two umimages, the pci and non pci version. so i will flash the non pci version to b04 like you said.

The package from the 2nd post just contains the uImage for the Pro. The package from the 8th post contains both uImages. Everything else is the same.

shv, thanks.

i downloaded the warheads updater package from the other link. the update-kernel.sh runs the same commands as you describe only uimage is different filename it is called uimage.nopci and uimage.pci

I can extract your package and run the commands you provided manually from shell. the script also moves modules.
afterwards in other folders. After I have placed this kernel package on my nand flash. what do I need to place on my usb stick? To boot debian and get usb sound working ?

also looks like the script runs from archlinux. i dont have arch on my stick at the moment but debian from varkey.
can i use these commands to flash nand also from debian or do i need to get archlinux working on my stick ?

You should extract my kernel package in the root folder of varkey's debian rootfs. You might need to install the mtd-utils package if this is not yet available in varkey's rootfs. Afterwards you should execute the two commands to flash the new uImage into the NAND flash. If everything is OK reboot the device.

and now? reboot and hope everything still works?

i edited the modules and rc.config according to your post

i'm scared to do a reboot :D

now i should be able to boot your rootfs. i am going to look it up and place it on my usb stick. kernel is upgraded varkey doesnt boot anymore. how i can find the post again to your rootfs which has usb support.

rebooted again. now it boots. but I want a clean debian os. now its a mess. varkey + your files. think its better to use yours. where can i find latest rootfs you made ?

Now extracted your rootfs i found on german website (it was top sticky post). afterwards copied over and extracted your latest kernel and edited the /etc/modules.

stick boots fine and kernel is loaded:


root@debian:~# uname -a

so now lets try to get usb soundcard working.

also sound modules looks like they're loaded.

but the problem.. how to get alsa . alsa keeps saying no soundcard found.

root@debian:~# alsactl init

i reinserted usb sound card. and dmesg says':

from this page: http://alsa.opensrc.org/Usb-audio#Tuning_USB_devices_for_minimal_latencies but lots of errors

The sound driver are not fully working (see snd_page_alloc messages)! Maybe the kernel don't support your specific device. Currently you have a non PCI uImage but modules which are compiled for PCI. This normally works well. If I have time I will provide you a module package which is completely compiled for Non-PCI. If this doesn't work the only way is to compile the driver for your sound card or to use a sound card which is already tested and working (e.g. this one: Link).

thanks shv. i'll wait for your module package

my soundcard has spdif out i need that to connect it to my dac. The card works under linux. i had it working on a iomega iconnect running debian (used this guide: http://m.kroonen.eu/wiki to get debian on the iconnect) but I am using the iconnect for other purposes at the moment. i'll wait for your package, if it doesnt work I will get a raspberry pi which only is 35 euro these days ;)

orded a raspberry pi, hope it will arrive tomorrow. Will use the pogo as web server or something else which doesn't involve usb devices.
