Question on i.MX6's PCIe RX

t_kuha — Fri, 26 Jan 2018 02:03:50 GMT

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.

Is there any examples of i.MX6 (RC) receiving Memory Write TLP from EP device?
