phy link never came up issue ?

[peteramond]

Dear All,

My hardware is based on iMAX6Q processor and the design most similar to nitrogen6_max development board. 

I'm using Boundary devices u-booot version 2016.03 and linux kernel - Linux-boundary 4.1.15.

I am trying to interface PCIE with TW6865 Intersil video chip

I did following latest hardware change to PCIE clk differential pair as NXP explained in their hardware guide lines.

But I'm getting following error while kernel loading. And PCIE is not working.

imx6q-pcie 1ffc000.pcie: phy link never came up
imx6q-pcie 1ffc000.pcie: Link never came up
imx6q-pcie 1ffc000.pcie: failed to initialize host
imx6q-pcie: probe of 1ffc000.pcie failed with error -110

Could you please give me a solution for this.

Regards.

Peter.
