[alsa-devel] Audio driver for dbAu1250 Development board

[Manjunath A M]

Hi

I am trying to make audio up in dbAu1250 Development board, I downloaded 
linux-2.6.29.4 kernel from the site 
"http://www.linux-mips.org/pub/linux/mips/kernel/v2.6/ " and
applied the patch "asoc-v2.6.29-rc8-2009-03-17.patch"downloaded from 
"http://opensource.wolfsonmicro.com/~git/asoc/"
but while compiling i am getting the bellow errors

****************************************************

before applying the patch the board was working but the audio was not 
working..
can you suggest me which kernel source you used and how you got the 
audio working for your board.
can you send me the sample kernel image "vmlinux.srec" image for testing..


Thanks
