Hi and thanks for the quick reply.

Do you know if there is some existing library that we can use for that purpose?

Hi Rajul,

We want to stream audio data from the AM2612 to an TAS2781 amplifier, 16bit 48Khz.

Hi Daniel,

After completing the analysis, we found out it is feasible in terms of porting PRU-I2S solution from AM263x to AM261x streaming audio data to TAS2781 amplifier.

Best Regards,

Rajul

Hi Rajul,

That's great news, I guess our FAE will let us know when you have some PRU code to share with us?

Best regards

Daniel
