A Raspberry Pi3 B+ was outfitted with: ubuntu-mate-18.04.2-beta1-desktop-armhf+raspi-ext4.img which indicates that the B+ is the recommended hardware. That being said, at bootup, the rainbow screen (indicating an incompatible OS) is briefly observed (~8 seconds):
then displays an error message:
[2.568964] Error: Driver 'sdhost-bcm2835' is already registered, aborting...
proceeds to the mate desktop
- What must be done to prevent the rainbow screen + error message?
- If the OS was truly incompatible, should I expect that nothing should work?
