Public bug reported:
I installed the Ubuntu 20.04 Raspberry version
I tried to modify firmware/usrconfig.txt. Always the same result...
After modifiying the desired configuration and reboot, the RPI4 enters a
loop trying to boot: the color image blinks, and immediately turns off.
Then boot again, a blink of the colored image, turn off... and so on.
