Hello,
In a custom product development we sometimes see that the McASP transmit DMA stalls permanently
without obvious reason.
We are using OMAP L138 (silicon revision 2.3) running Linux on ARM + custom DSP application (40kHz sample data rate).
Under “normal” conditions this setup runs for days / weeks without a hitch, but under certain
circumstances when a Linux application makes heavy use of the
memory and IO the McASP “stalls” permanently
Any idea what could cause this issue?
Thank you!
