Hi,
I am trying to copy data from DRAM to DRAM using EDMA (AM335X MCU)
But there's a problem, it seems some data was missed by EDMA
As following:
1. u8 src[1024] to u8 dst[1024] , then I assign 0~1023 into src array
2. After running EDMA, only a part or none of elements were copied, and the callback functions was invoked successfully.
It looks like a cache coherence problem, DRAM contains old data when I calling EDMA function
I can not find an option setting or parameter setting related to my question in AM335X spec
Can anybody help me figure out how to solve this problem?
Many thanks!
Regards,
Eric
