LattePanda-Mu/Softwares/BIOS

BIOS

This repository includes official releases and beta versions of BIOS for various branches, as well as related tools.

• ⚠ Generally, you should only upgrade the BIOS of the same branch. Cross-branch upgrades should only be performed when testing different BIOS features.
• ⚠ Upgrading the BIOS across different branches will invalidate the Secure Boot keys.
• ⚠ Upgrading to the incorrect BIOS branch may result in some functions of the carrier board not working properly.
