Trying to get DSP to work with Linaro

[TheAlphaNerd]

http://elinux.org/BeagleBoardUbuntu#DSP states that I need as a
requirement a Kernel built with: "CONFIG_TIDSPBRIDGE=m" .

How would I got about building and installing TIDSPBRIDGE ???

[Robert Nelson]

First check, might be enabled:

voodoo@beagle-xma-512mb:~$ zcat /proc/config.gz | grep TIDSP
CONFIG_TIDSPBRIDGE=m
CONFIG_TIDSPBRIDGE_MEMPOOL_SIZE=0x600000
# CONFIG_TIDSPBRIDGE_DEBUG is not set
CONFIG_TIDSPBRIDGE_RECOVERY=y
# CONFIG_TIDSPBRIDGE_CACHE_LINE_CHECK is not set
CONFIG_TIDSPBRIDGE_WDT3=y
CONFIG_TIDSPBRIDGE_WDT_TIMEOUT=5
# CONFIG_TIDSPBRIDGE_NTFY_PWRERR is not set
# CONFIG_TIDSPBRIDGE_BACKTRACE is not set

For building linaro's kernel, linaro.org has some hints..

So now this is where things get a little bit hairy. I have recompiled
the kernel following the instructions on the linaro wiki. Using zcat
I am able to confirm that the tidspbridge module has been enabled
including all the above mentioned configurations. I have followed the
steps from the beagle ubuntu wiki on installing dsp utilizing your
scirpt.

dsp-test works, although I am getting an error message to my main
console of procwrap_Detach: deprecated despbridge loctl

Now I've tried to setup ALSA...

supo apt-get instal alsa-base alsa-utils

this installation goes fine (or so it would seem). Until I try and
launch the alsa mixer... when I try
linaro@speaker-bot:~$ alsamixer
cannot open mixer: No such file or directory

just in case it was a permissions error I tried to verify that linaro
was added to the audio group and also tried running command as root

root@speaker-bot:/home/linaro# alsamixer
cannot open mixer: No such file or directory

cat /proc/asound/cards is listing no soundcards as available... so
perhaps there is a step I missed in the setup

So I've made a little bit of progress (I think)

I ran apt-get install oss-compat and now my lsmod looks like this

linaro@speaker-bot:~$ lsmod

although I am still having the problem with alsamixer not working, and
with no list of soundcards...
