1. P1020 by PCIE and exchange chip BCM56450 mapping a momery, about read and write,reverse order is right, Positive sequence is wrong,such as writing 5,4,3,2,1,that is right, writing 1, 2, 3, 4, 5 is wrong, please if have a register set can be positive sequence writing?
2. Is there a register can set the big end and small end?
 
There is no such Settings, whether need to change the software?

Thanks!

PCIe is inherently little endian. See P1020RM, Section 14.12.1.2
for advanced discussion.
