Hi Javelin, below are some of the tests I completed yesterday, but I could not capture the logs. It seems that this was working on the (very) old armbian version 
 
	 
 
	Armbian_24.8.1_Odroidhc4_bookworm_current_6.6.47.img
 
	·        No changes - starts, soft reboot is not working – voltage issue
 
	·        <0x44 0x06 0x03> - starts, soft reboot is not working – voltage issue
 
	·        <0x44 0x06 0x06> - does not boot
 
	 
 
	Armbian_23.8.1_Odroidhc4_bookworm_current_6.1.50_minimal.img
 
	·        No changes - starts, soft reboot is not working – voltage issue
 
	·        <0x43 0x06 0x03> - starts, soft reboot is not working – voltage issue
 
	·        <0x43 0x06 0x06> - does not boot
 
	Note, that the first value differs (by default) comparing to the latest version.
