Ok that didn’t work. Make another change to the DTS file, recompile, reburn, and try again. Aw fuck it. I’m tired. I don’t know why this isn’t working. Having some sort of Ethernet PHY issue on an i.mx8mp dev board. The first PHY works fine. The second will not come up. It works on kernel 5.15, but not on 6.1. The PHYs are identical (ADIN1300). Tomorrow is another day I guess.
