Studio HEX in release has all the data?
Since the PCBA does not know about ELF files, I've extracted the HEX for the flash and fuses. Seems that is all I require (I write the EEPROM at run-time). Is it possible to "mix...

meolsen wrote:No, the hex from Studio only contains flash. The .elf contains everything. So what would be the correct way to have the MCUs programmed in an assembly line? They...

Why two different power supplies causes my sensor to react differently?
@Kartman   I have the (PC) scope connected to a laptop which is running on battery, so the scope is floating. The circuit with the DC-DC converter is also running on a...

No current production support high voltage programming?!
So the good news are that I was able to cut the required trace on the Arduino PCB and now they enter to debug mode without a problem. So the fuse was set, it just could not manage...
