Hi All,
I am in an unfortunate position of developing ALSA kernel modules separately(as a kernel build) and populating the necessary files to a filesystem. I am able to install all the ALSA modules on the board I am working on successfully. Can someone point me to how to start with the configuration part on the board to populate /proc and /dev entries?
My config(as per the alsa diagnostic script) is:
