I recall having seen this during my early bring-up of mainline U-Boot on our i.MX 8M Plus based Verdin. However, it turned out to be some configuration issue of sorts on my side. Unfortunately, I do not remember the exact details resp. after much debugging I then went back to the EVK configuration changing only the console UART and then piece by piece adopted it further to our hardware and haven't seen it ever since. As I am currently anyway working on U-Boot stuff I gave today's master a spin and can assure you that EQOS works on our Verdin iMX8M Plus without any issues. Sorry, that I can not give you any better more specific answer. > Best regards, > > Tim Cheers Marcel
