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
