Hm, I retried with defreeze and freeze and now instead of armbian-firmware-full, the armbian-firmware got hold. For security I will also set again the armbian-firmware-full on hold... Better safe than sorry.
Apologies, above happened on my rock64. Strange though: the rock64 image holds armbian-firmware, the rockpro64 holds armbian-firmware-full? Or is that because I added the headers as well on the rockpro64 and not on the rock64...?
Hm, tried to update packages and the firmware using armbian-config, and it updates the full. Is it possible that the omv (installed using armbian-config...) uses a different update strategy and uses the armbian-firmware NOT full?
Will set a hold on both to be sure...
