Hello,
Have You used recommendations of app note AN12444
(PCIe Certification Guide for i.MX8 Series) ?
In particular, section 2.3 (Test environment).

Hello,
We have referred to the guide and checked the instruction also section 2.3. I believe it had been done properly. We had accessed the following register, but it didn't work.
