Hi there,
please, read our statement about the future of Moitessier HAT.
Rooco's plans with Moitessier HAT
Precompiled Packages
We provide ready-to-install .deb packages for major kernel releases of Raspbian Buster and Raspbian Stretch. Please, select the package that fits to your kernel version.
Installation via Command Line
sudo dpkg -i package_name.deb |
Temporary fix for kernel version 4.19.118
If your Rasbpian runs on kernel version 4.19.118, you will face a bug in the DTB (device tree blob), which will make your system unbootable.
There are two scenarios:
- Kernel update already installed, Raspberry Pi not booting anymore
- Kernel update not installed
Installation process – Scenario 1
- Turn off the Pi and unplug the power supply
- Remove the SD card from the Pi
- Insert the SD card into a PC/laptop
- Open file /boot/config.txt
- Delete line “dtoverlay=i2c-gpio…” and save file. Keep the line feed at the end of the file, i.e. there is an empty line at the end!!
- Remove the SD card from the PC/Laptop
- Insert the SD card into the Pi
- Turn on the Pi and boot
- Download the latest Moitessier package
- Install the Moitessier package. The system will reboot automatically afterwards, but system will hang during booting.
- Repeat steps 1 to 8 to disable the i2c-gpio overlay.
- Install the bug fix: sudo moitessier/scripts/bug_fix_kernel_4.19.118 moitessier/dtbo/i2c-gpio_bug_fix_4.19.118.dtbo
The bug fix will also update/upgrade your system. - Reboot the Pi
Installation process – Scenario 2
- Update to the latest Raspbian and kernel version

Current Moitessier Driver Version: 2.2.2. See release notes.
Raspbian Buster on Raspberry Pi 3 and Pi 4
We have put together the kernel drivers for Raspberry Pi 3 and Pi 4 into one versatile package. Now, you can install the same package on either systems.
Raspbian Buster on Raspberry Pi 3 (legacy)
Packages for Raspberry Pi 3 only. These are legacy packages. For up-to-date systems, please use packages listed above under Raspbian Buster on Raspberry Pi 3 and Pi 4.
| Package | Kernel Version | Moitessier Firmware Version |
| Buster (Pi3 legacy): moitessier_4.19.66_armhf.deb, checksum | 4.19.66 | 1.3.0 |
| Buster (Pi3 legacy): moitessier_4.19.57_armhf.deb, checksum | 4.19.57 | 1.3.0 |
Raspbian Stretch
| Package | Kernel Version | Moitessier Firmware Version |
| moitessier_4.19.66_armhf.deb, checksum If directly updating from 4.14.x do: Install - Reboot - Install again |
4.19.66 | 1.3.0 |

Release Notes
| 2.2.2 |
Added support for kernel 5.10.63. |
| 2.2.1 |
Added support for kernel 5.10.11. |
| 2.2.0 |
Bug-fix: Some GNSS messages were dropped, due to an initialisation error. Only GSV was processed. Added support to disable/enable GSV messages. |
| 2.1.1 | Bug-fix: TTY driver registration fails on Pi 3 if a major/minor device number is defined. The device number must be automatically assigned by the system since at least kernel 5.4.51. |
| 2.1.0 |
Temporary fix for kernel version 4.19.118. Added support for I2C GPIO device detection. |
| 1.9.0 |
Parameter DO_SHUTDOWN (Moitessier driver) can now be written from user space as well. Shutdown service supports shutdown and reboot, depending on the value written to DO_SHUTDOWN either by pressing the push button of the Moitessier HAT or writing the value directly via a terminal to the proper sysfs parameter (e.g. for testing purpose). Minor bug fixes to get rid of some warning during runtime (e.g. "warning: command substitution: ignored null byte in input"). Fixed not proper working shutdown service on some systems. |
| 1.8.1 | Moitessier shutdown procedure implemented as systemd service. If the process is killed it will be automatically restarted. |
| 1.8.0 |
- HAT firmware version 1.6.0 - Added new module parameters to the device driver for testing purpose only - Revised script for production testing - Fixed data loss when using the shutdown button |
| 1.7.0 |
Added support to read GNSS firmware version HAT firmware version 1.5.0 |
| 1.6.0 |
Added support to enable/disable GNSS NMEA sentences Added support to enable/disable shutdown button (Moitessier HAT 2 only) |
| 1.5.1 |
Fix "Raspbian does not boot" (rare cases) Fixed firmware update process breaks (rare cases) |
| 1.4.1 | Fix "System hangs when SPI is disabled" |
| 1.4.0 | Add support for shutdown switch (Moitessier HAT 2 only) |
