Hi Community,

I am working on a custom board of i.MX8MP processor with Linux 6.1.22, and am trying to test the eye diagram of PCIe. As I am following the instructions from https://www.nxp.com/docs/en/application-note/AN12444.pdf , there is no CONFIG_PCI_IMX8_COMPLIANCE_TEST=y within the config files. I have read and referenced to case:1352394 which mentioned about IMX6_COMPLIANCE_TEST, still not found in the configs. 

Is there a workaround for such case that I could reference to?

Thank you.

Will

Hi joanxie,

Thank you for the reply.
Just for confirmation, I would only need to add the "pcie_cz_enabled=yes" in u-boot to enable the mode, is that correct?
