Quite a puzzle, but we are getting there.

So it appears that I did actually have the correct schematics. The thing is that the PHYs are wired for MII at the PHY side, but the wiring at the AM335x also mention the RMII signal names. So it looks like it can run in both RMII and MII modes. The fact that you saw that the device tree is configured for RMII is a great help to me. That proves that the wiring is actually RMII compatible.

 

So thanks again!

Thank you so much! Just the info I was looking for.

would you also have a link to the AM335x ICE V2 board schematics? If I search for them through Google I only get the schematics for the V1 board, which seems to use MII instead of RMII.

It seems that it does not have a reference clock for the 2nd PHY.

Do I need to synchronize both PHYs to each other?
