Hi synid

"imx6q-cpufreq.. error" may be related to board design: please check

that it has pmic, as i.MX6Q Sabre SD reference board, refer to sect.2.5.3 CPU

Frequency Scaling (CPUFREQ), sect.2.5.2 PMIC PF Regulator attached Linux

Manual. Try to use nxp linux from source.codeaurora repository

linux-imx - i.MX Linux kernel

May be recommended to recheck board with Sabre schematic on

Schematics (1)
Design files, including hardware schematics, Gerbers, and OrCAD files.
SABRE Platform for Smart Devices | NXP

Best regards
igor

"not ok" does not show errors, it also shows "link up" .

You can try to experiment attaching other pcie cards or

changing pcie card from good to bad and compare.

Best regards
