Introduction

Preface

The AIBOX-K3 comes pre-installed with Linux. If the user wants to run
other operating systems, the corresponding firmware needs to be
flashed onto the motherboard.

The AIBOX-K3 offers flexible boot options. Generally, unless there is
hardware damage, the AIBOX-K3 development board will not become
bricked.

If an accident occurs during the upgrade process and the bootloader is
corrupted, making a re-upgrade impossible, it is still possible to
force-enter the flashing mode to repair it.
