PCIe on i.MX7

We are having issues getting PCIe to work on our i.MX7 board. We were told that PCIe is supported for i.MX7-sabresd in rel_imx_4.1.15_1.1.0_ga release, but we are also unable to get it to work on the SabreSD board (Rev. B). Is this a known issue with this board revision? Which revision was used to test PCIe?


This is the error:

imx6q-pcie 33800000.pcie: phy link never came up

imx6q-pcie 33800000.pcie: failed to initialize host

imx6q-pcie: probe of 33800000.pcie failed with error -22


To build the rel_imx_4.1.15_1.1.0_ga kernel, I am using the imx_v7_defconfig and enabling the configs described in the i.MX Linux Reference Manual:






Thank you,
