Hi TI engineer:
We have an application in which C6678 send 16KB DIO + doorbell to FPGA continuously. When we do this , a doorbell transfer will return error in every 100 transfer.The error completion code is 0x01. C6678 will stay in cc pend for 6-7 seconds during this error happen.
If we insert some delay between transferring, the error didn't disappear but became less.
DIO type :NWRITE,priority = 0;
doorbell priority = 1;
Could you tell us why this happen and how to solve it?Thank you very much.
