Hello @lupo
Currently I can’t help you with your problem, but I am facing with related issue. Could you describe me how to get working fec2 on collibri-imx7d?
my thread
I have problem with RMII clock in our design. It is not generated from Colibri board.
- do you use external 50MHz oscillator to clock PHY ic?
- which kernel do you use?
- is your device-tree same as posted here by @hyoungki?
Thank you in advance
