Other Parts Discussed in Thread: MCU-PLUS-SDK-AM243X
Dear Sir
I'm running the "UDMA Memcpy Polling Project" on MCU-PLUS-SDK-AM243X.
When I ran the sample program as it was, it worked normally, but when I ported the source to my project, TX_ERROR in DMASS0_BCDMA_0_TRT_CTL Register became TX_ERROR=1 and transfer was not possible.
As for the meaning of the TX_ERROR bit, I have determined that a bus error has occurred from the explanation in "11.1.4.22.3 Bus Errors", but is my understanding correct?
I just couldn't find any more error information from the TRM.
What are the possible causes of bus errors in BCDMA transfers?
Best regards
