I updated my kernel bootloader to 5.4.42-v7l on my Raspberry Pi 4. It seems that there is not yet a driver for the Moitessier HAT for this version. When will the new driver be released? Is it being worked on?
The reason I updated is because the beta bootloader for booting directly from USB has been released. I have been waiting for this feature to be updated on the pi 4. I am not interested in testing the beta release, but in preparation, I did install the stable version. That is when I saw that the HAT quit working.
I performed the following steps outlined here:
