Hi Bin,
1024-byte is just for confirming the driver performance; in fact, 512-byte is enough for my applications.
As I mentioned before, it fails when I play a 48k wave file by UAC2 with 512-byte packet, but it successes playing a 16k wave file with 64-byte packet.
I would like to make sure whether original Linux f_uac1 and f_uac2 modules are workable in AM335x SDK7 or not?
Thanks for your effort,
Sam
