Hi Mark,
I found the problem, I was not aware about the patch "ASoC: DaVinci: remove
requirement that dma_params is 1st in structure", that's why the davinci pcm
open function was failing because the dma_params was not assigned properly.
This is current output after that change:
root@dm365-evm:~# arecord -D plughw:0,0 | aplay -D plughw:0,0
Recording WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono
Playing WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono
root@dm365-evm:~# arecord -D plughw:0,1 | aplay -D plughw:0,1
Recording WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono
Playing WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono
I need to verify further more.
Thanks,
Miguel Aguilar
