My customer reported an issue related to EDMA3 operation.
When the issue happens, DSP seems hangs up.
Customer found after the issue, EMDA3 ERRSTAT register value is 0x9 (MMRAERR and BUSERR are set).
I think this means bus error happens due to an invalid address is accessed.
Customer checked ERRDET register and STAT bit field is 0x9. This means write error.
What STAT=0x9 exactly means?
Any debugging recommendations?
Thanks and regards,
