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