Hi all,
I have a few Q's regarding the alsa driver I am working for. I am using i2s contriller with standalone UDA1341 codec for my board.
Now, I have realised I have to write ALSA driver PCM( data-path) and Controls( uda1341 mixer) for ALSA drivers to work.
In ALSA PCM, I want to copy the Tx/Rx h/w FIFO buffers to PCM sunstream. As my board does not support mmap, dma, what should I do to transfer these buffers to PCM substream . I kown I have do this while pcm_trigger() call but realy don't know what to do?
Kindly share your views and reference..
Regards
Raja Mallik
