This tar.gz contains a auto flash tool for quick flashing Arduino IDE compiled bin file to the DevTerm keyboard while the keyboard is plugged in the DevTerm and DevTerm is running some linux system.
DO NOT confused the bin file in the tar.gz with other devterm.kbd.***.bin files, they are not the same thing.
So do not use devterm.kbd.***.bin with this flashing tool.
Here’s how you can flash the firmware on DevTerm(A06 or CM4) or a PC running Ubuntu 22.04:
tar zxvf devterm_keyboard_flash.tar.gz
.sudo apt install -y dfu-util
.cd devterm_keyboard_flash
.sudo ./flash.sh
.
