How to set iMX6 PCIe Clocks ?

peteramond — Mon, 17 Sep 2018 11:51:55 GMT

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

I'm can see following message while loading the kernel. What is the problem here ?

Could you please tell me how to set the ENET PLL (PLL6) 100 MHz (SATA) PFD output in order to access the registers in the PCIe IP block ? Is that the problem here ?

Can you tell me where should I set above clocks ? Is that in uboot ? Can I have file location ?

[ 3.492265] imx6q-pcie 1ffc000.pcie: phy link never came up
[ 3.497864] imx6q-pcie 1ffc000.pcie: failed to initialize host
[ 3.503834] imx6q-pcie: probe of 1ffc000.pcie failed with error -22

Thank You,

Peter.
