[SOLVED][OP2] Latest beta does not boot on RPI3+ with Moitessier HAT 1

This has been reported here: http://forum.openmarine.net/showthread.php?tid=2152
But better use this specific thread to solve it.

this is my test this morning:

- Raspberry 3B+ and moitessier HAT 1
- Download and install latest OpenPlotter Moitessier HAT edition NOOBS file.
- In first boot skip the system update. kernel is 4.19.75 v7+, preinstalled driver match this kernel. Everything works OK.
- Reboot. Everything works OK.
- Update system to kernel 4.19.93 v7+ and reboot.
- Obviously the installed driver does not match the kernel and moitessier hat does not works. Download and update driver from openplotter-moitessier app to 4.19.93_1.4.1
- Reboot. Everything works OK.
- Disable SPI and I2C from raspberry preferences. System hangs.
- Restart. The system starts nornally with SPI and I2C disabled so no data from the HAT.
- Enable SPI and I2C. Everything works OK.
- Reboot. Everything works OK.
- Put the same SD into Raspberry 4. Everything works OK.

My hypothesis is that my moitessier 1 has been already flashed with the new firmware.

emilecantin please could you try with the starting edition? download and update the system to the new kernel 4.19.93, install openplotter-moitessier app from openplotter-settings and download and install the matching driver.
