Hi, I am currently working for PCI express support.. I am facing some issues with writing data to pcie registers. If I write a data to a register than again read it back to see if it is written I get results like 0xFFFFFFFF.

Thanks in advance.

It is impossible to help without look on your code.

Does the device exist?

Which registers are you trying to write?
