Hello there ! 
	 
	- nanopi R3S 2GB ram / 32 GB SD card and 32GB MMC here.
 
	- Image running: Armbian_25.5.1_Nanopi-r3s-lts_noble_current_6.12.33
 
	 
 
	An upgrade (armbian-upgrade or apt-get upgrade), both on SD card or MMC, breaks boot of the system, reboot or cold start fails, stuck in system red-light. 
	Both SD or MMC boot at broken. Need to reflash the SD and boot + reinstall. 
	 
	See attached some logs.
 
	 
 
	Thanks !
