Dear @gabriele-andrea.blasciuc1 ,
Does that mean, you could flash the hex files provided as part of DRIVE OS but custom hex you prepared has issue?

Yes, i would like to know what lead to “version info not found in hex file” as i cannot see the source code as its a lib. with MCU_Flashing is working, the mcu version is found at the address specified. For flash via thor is seems that version is expected to be at another location?

Do you see any confirmation message like printing version info in log when using MCU_flashing.py?
