Hey @ClaesM,
Great to hear you are finding the EEPROM Firmware Updater plugin useful, and thanks for the kind feedback. Your suggestion about integrating Boot Order control and much more is already being Published here.
It will eventually allow you to inspect and adjust the Raspberry Pi boot configuration directly from Volumio, without external tools. The plugin is not ready yet, but it will be published for testing once the core logic and safety checks are complete.
Kind Regards,
