[U-Boot] PCIe on the i.MX6?

Hello,

Does anyone have any experience with PCIe on an i.MX6 processor (in particular the i.MX6 Solo)?

I can access the config space of my PCIe device but can't seem to get its BARs mapped in properly. I thought I had the viewports set up but when I try to access the space, I just get a processor lockup.

Any suggestions would be greatly appreciated.

Thanks, Carolyn
