Hello,

I am trying to figure out how to  use the imx7d PCIe interface. Is it supported in the current kernel release. It is not working on my MCIMX7SABRE board. The board revision is C.

            Thank you.

Hello,

  PCIe is not supported by the default kernel configurations on i.MX boards.

Please configure kernel, using chapter "PCI Express Root Complex Driver"
of "i.MX_Linux_Reference_Manual.pdf".

  Also, please look at PCIe on i.MX7

Have a great day,
Yuri

Hello,

I followed the suggested link and still it is not working.

The PCIe clock in time of probe is 118Mhz instead of 100Mhz and it makes all the problems.

     Any suggestions?

      Thank you, Leonid.
