Question on i.MX6's PCIe RX

Hi,

I have a problem in receiving data over PCIe from EP device. (TX is Okay.)

How can I know the RX status?

Is there any register (or something like that) for debugging?

Regards,

Hi t_kuha

in general may be recommended to perform pcie compliance tests:

QA: About i.Mx6 PCIe compliance 

How to setup i.MX6Dual/Quad and i.MX6Solo/DualLite Linux software for PCIe compliance Test? 

I am afraid there is no way to know the RX status from i.MX6 side, except measuring its level with special equipment.

Best regards
