Downloading to Mixtile Blade 3
Blade 3 comes with Debian 11 pre-installed, and it can be updated with any custom built firmware. The system firmware may be updated via either an USB cable or a MicroSD card. Under normal circumstances, the [MicroSD card method] is preferable for the users. Users with specific requirements who need to burn the system with USB cable and SD cards should back up their data in their own method.
The A/B (Seamless) system update is used by Blade 3. Blade 3 will not brick unless the hardware is damaged.
