Hi Bert,
Have you been able to debug the coredump using coredumpctl providing the process id.
Also need more information on your setup with MCASP. Looks like you are using MCASP0, share your DTS file and other details about what is MCASP0 interfaced to, what are the clock configurations(MCLK, BLCK and LRCLK/Framesync). Is this a custom board?
Best Regards,

HI Suren
I use the TI EVM board SK-AM62-LP and run the Linux SDK 10.01.10.04, not change any code. you can try yourself
Hi Bert,
On AM62x we use MCASP1 interfaced to audio codec. McASP0 is disabled.
can you try to dump registers for MCASP1 and you should not see any errors.

Hi Suren
0x0002B10000 is MCASP1, I have tried it . you can see the log above
Hi Bert,
In order to dump the MCASP registers you need to be playing or capturing audio.
I was able to dump the register while executing the below commands:
arecord -D hw:0,0 -r 48000 -c 2 -f S16_LE test.wav -d 10
Hope this helps
Best Regards,
