MightyHat R3 Raspian Buster BOOT issue.

[Magnus]

Hi

I have an issue when trying to use Raspbian Buster together with MightyHat R3 and Raspberry 2 Model B.
During boot there is somekind of crash that make the screen look like the attached picture.

If the MightyHat is physically removed from the Rasperry PI then Buster boots as expected.

This worked just fine with my old Jessie build.

Any ideas?

Did you turn off login over serial port in raspi-config?
