Flash, control or configure MediaTek boards, and in particular the Genio evaluation kits

📦 Install

sudo snap install genio-tools

To disable strict confinement and grant the Snap elevated system permissions for development purposes:

sudo snap install genio-tools --devmode

🔌 Udev Setup

After installing the snap, run the setup app to generate a setting up script for current user:

snap run genio-tools.setup

Then, install the necessary USB udev rules:

sudo bash ~/snap/genio-tools/current/common/install-udev-rules.sh

Alternatively, for a one-line install using eval, run:

eval "$(snap run genio-tools.udev-script)"

This will output and immediately execute the udev install script for current user.

⚠️ Limitations (when Installing without --devmode)

• genio-config Tool

The genio-config tool does not work inside the snap package because it tries to access udev rule files directly. Since the snap lacks the unsafe system-files interface, it encounters permission errors.

However, if the above setup script runs successfully, fastboot and all necessary udev rules are already applied to your system, so running genio-config is not required.

• Access to /dev/gpiochip0

Tools like genio-flash and genio-board require access to devices such as /dev/gpiochip0. Snap’s default confinement restricts this, causing errors like:

WARNING:root:[Errno 1] Operation not permitted: '/dev/gpiochip0'

• Workaround

To enable GPIO control and related hardware access, it is recommended to install the Snap using --devmode, which disables strict confinement and grants the Snap elevated system permissions:

sudo snap install genio-tools --devmode

Note: If you need to use adb or connect to UART without root privileges, an additional udev rule is required. Please refer to the official MediaTek documentation for details:
