RTOS/OMAP-L138: Audio underrun/overrun

Hi Andrej,

Have a look at section 25.0.21.6.2 Buffer Underrun Error - Transmitter and Section 25.0.21.6.3 Buffer Overrun Error - Receiver and follow the procedures described there.

Basically for underrun, you should check the Transmitter Status Register and upon reading 1 in bit[0] XUNDRN you can print that underrun occured.
For overrun similarly you should check bit[0]ROVRN of the Receiver Status Register.

Best Regards,
Yordan

Hi Yordan,

I use McASP SYS/BIOS driver from PDK (DMA mode). What is the best place in code to handle these errors?

But I want to use driver interfaces.

Hi. Any answer?
