I use:
Bios_5_42_01_09.
Ccsv6.
Edma3_lld_01_11_03_01.
Pspdrivers_01_30_00_05.
Xdctools_3_30_03_47_core.
Problem in string number 99.
I can get data from codec. I forever wait SIO_ready. It is not work when i use 2 or more buffers. When buffer is one it is all works.
I not use aic31 driver and audio driver, only mcasp.
Part of my code:
