EDMA write PCI fail in 6455

HI,

I'm using PCI interface in C6455. When C6455 writing to PCI host(a X86 board), i found "memcpy" can write successfully, but EDMA fail.

Since memcpy works, it means memory map configuration should be correct(i'm using PCIADDSUB23).

EDMA configuration also confirmed to be correct, since if i changed the destination address to other space(such as ddr2), data transfer turned to be correct.

So it's weird? Anybody has any idea?

thanks,

Weslly
