kernel configuration for i.MX8 PCIe cerification

m_c — Thu, 03 Oct 2019 14:33:06 GMT

In application note an12444 <http://nxp.com/doc/an12444>, 2.3 test environment said set CONFIG_PCI_IMX8_COMPLIANCE_TEST=y.

But we can't find it in kernel 4.14.98, but found CONFIG_PCI_IMX6_COMPLIANCE_TEST.

Which kernel configuration should we used for PCIe cerification?

Hello,

set "CONFIG_PCI_IMX6_COMPLIANCE_TEST=y", and rebuild the kernel image.

Regards,

Yuri.

HI m.c:

Does the PCIE eye pattern test signal come out after "set "CONFIG_PCI_IMX6_COMPLIANCE_TEST=y", and rebuild the kernel image" ?　I did the same thing , but no signal.

HI m.c：

Thanks.

After tested, we found that PCIE1 have the signal but PCIE0 no, but PCIE0 is working for my wifi module.
