TDA4VM: c66x dsp audio example

Wang Hao

Part Number: TDA4VM

Hi, experts:

I'm doing some audio evaluation on J721E EVM, and I want to make C66x dsp play sound , I see there is some example in PDK's mcasp driver directory, but document said most of them is not supported by j721e_evm, is there any example that make c66x dsp play sound?

ps: the sdk version I use is ti-processor-sdk-rtos-j721e-evm-07_03_00_07

You can find audio example in Processor SDK Linux.

We don't have DSP audio examples.

I using the command "aplay -Dplughw:j721ecpbanalog,0 <wav file path>" to play sound, and I plug a 3.5mm headset in three Head Phone OUT Port. The command finish without error, but I can't hear any sound. Are there something wrong?
