Hi Neeraj,

I finally figured this one out. It turned out that that the hardware designer decided to put a 10k pull down on the usb0_id line. Strangely enough this did not have an effect, at least not noticeable, during Linux operation, only in U-Boot.
I also thought that U-Boot was trying the CPSW in MII mode and was giving a timeout because our board uses RGMII. It doesn’t matter how the board is identified, Beagle Bone Black or Pocketbeagle, with the resistor removed and “setenv ethact usb_ether” it will use the USB RNDIS and work correctly.
My statement that it didn’t work on a Pocketbeagle/OSD3358-SM-RED board was incorrect. I think during all the testing some confusion occurred.

Thanks a lot for your input.

Regards,
Stephan
