Downloading the source code, installing the SDK and building the firmware can be done using the following commands:
git clone --recursive https://github.com/badgeteam/mch2022-firmware-esp32
cd mch2022-firmware-esp32
make prepare
make buildFlashing the firmware to a device and starting the debug monitor can be done using the following commands:
make flash
make monitorIn mch2022-tools you will find command line tools to push files and apps to the badge etc., and a short manual on how to use them.
Create /etc/udev/rules.d/99-mch2022.rules with the following contents:
SUBSYSTEM=="usb", ATTR{idVendor}=="16d0", ATTR{idProduct}=="0f9a", MODE="0666"
Then run the following commands to apply the new rule:
sudo udevadm control --reload-rules
sudo udevadm trigger
While we have no idea why Canonical thinks breaking things by forcing Ubuntu users to use a bad software distribution system, we do have a solution!
Install the Chromium snap package, then run the following command (in addition to adding the udev rule above). If you already have the badge connected turn it off and back on after running the command.
sudo snap connect chromium:raw-usb
