Ethernet device is not detecting on ubuntu 20.04 LTS on BBG

Correct, that config doesn’t fix it… It’s just the new driver…

Like i said, TI changed the cpsw driver on AM335x…

The work-around patch only works with the older pre TI_CPSW_SWITCHDEV driver…

Right now, your best options are to use v4.19.x or 5.4.x…

Or pick-up a new BBB with a hardware fix. This issue only affects a small percentage of boards.
