Hi @Olivier GALLIEN ,

Thanks for your response.

Now I have already realized the recording function using alsa-lib on Cortex-A7. But on Cortex-M4， I still don't know how to configure SAI2 /CODEC(cs42l51)/I2C1. Even more, I can't find the codec interface in STM32Cube_FW_MP1_V1.2.0.

How can I get the codec APIs? And is there an example like 32L496GDISCOVERY/Demonstrations/Modules/audio_recorder can be shared?

Whether it just can be realized on OpenSTLinux ？ Also, I cant find the FatFs Middlewares. Does it support on Cortex-M4?
