Firmware and Drivers for Moitessier HAT

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:

  1. Kernel update already installed, Raspberry Pi not booting anymore
  2. Kernel update not installed

Installation process – Scenario 1

  1. Turn off the Pi and unplug the power supply
  2. Remove the SD card from the Pi
  3. Insert the SD card into a PC/laptop
  4. Open file /boot/config.txt
  5. 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!!
  6. Remove the SD card from the PC/Laptop
  7. Insert the SD card into the Pi
  8. Turn on the Pi and boot
  9. Download the latest Moitessier package
  10. Install the Moitessier package. The system will reboot automatically afterwards, but system will hang during booting.
  11. Repeat steps 1 to 8 to disable the i2c-gpio overlay.
  12. 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.
  13. Reboot the Pi

Installation process – Scenario 2

  1. Update to the latest Raspbian and kernel version

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.

- 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
