C6748+SYSBIOS+EDMA3+Cache
L2 Cache is 256KB.
In CCS 5.5,MAX_ACOUNT = 10,MAX_BCOUNT = 10, the project Application/EDMA3 runs nomally.
However, MAX_BCOUNT is modified from 10 to 512.Then run the project, a mistake occurs.
#define MAX_BCOUNT (512u)
before running, _dstBuff[] is all 0
after running, _dstBuff[0..9] is 0, the other members of _dstBuff[] is correct.
It seems that the first 10 bytes are not transported by EDMA3.
What's the reason of the problem?
