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

[Sailoog]

I have a provisional solution for users with a very old firmware installed in Moitessier HAT 1:

1. DO NOT use OpenPlotter Moitessier HAT edition, use OpenPlotter Starting edition.
2. Mount your HAT 1 in a RPi3 or RPi4 running OpenPlotter Starting edition. SPI should be disabled and openplotter-moitessier app should not be installed by default.
3. Update to latest kernel with:

Code:

sudo apt update
sudo apt upgrade

4. Edit /boot/config.txt file and add this line:

Code:

dtoverlay=i2c-gpio,i2c_gpio_sda=2,i2c_gpio_scl=3,bus=3

5. Reboot
6. Enable SPI in Menu->Preferences->Raspberry Pi configuration->Interfaces.
7. Install openplotter-moitessier app
8. Go to openplotter-moitessier app and in Drivers tab click on Download to get the latest package moitessier_4.19.93_1.4.1_armhf.deb and install it.
9. After installing the drivers and updating the firmware of your HAT 1 OpenPlotter will reboot and you are done.
10. Now you can use OpenPlotter Moitessier HAT edition if you want.

I will modify openplotter-moitessier app to do step 4 when installing and make this easier.

Test and report please.
