We currently support

3 Tx instance using one PRU with 32 bit with 2 channels (L and R) 48 khz sampling rate

2 Rx instance using one PRU with 32 bit with 2 channels (L and R) 48 khz sampling rate

Hi Nilabh,

It very excited to hear that! It makes up for the AM26's lack of audio interface.

Where I can get more information for this, such as demo. Once the customer need to use this feature, I can find the information in time.

Best Regards,

Zane

Could you please send me an email with the above requested info at nilabh@ti.com. I will be able to share more info there. We are also working on a alternate implementation using SPI but that is still wip.
