hi:

I am using C6678 EDMA0, and I make 8 cores to use 8 shadow regions each other with different channel and param, then I  use Manually-Triggered way to transfer together 8 cores(group all cores). When EDMA0 transfer over by pollling the IPR, I check the data, find that the first data is not right,  But When I check the memory, the source data is the same with destination data.Then I have a delay about 1 second when the EDMA test over, Now it is ok! It seem thant when I check the data, the EDMA have not transfer over although the IPR is ready.

I test my EDMA0 transfer function for core0 to core7 one by one, It's all OK.

I am not sure if 8 cores transfer together in parallel have  some problem!

Anyone can help me?

Regards,

Si
