I have 2xATMEGA328 that make a blank screen after several day of playing on same makerbuino. I have swap this 2 atmega with my 2 makerbuino.
I think I have a solder joint problem, on one makerbuino PCB.
control C trick not working: only blank screen for while.
I am looking for a easy way to flash the ATMEGA with a arduino UNO, but tutorials is too hard and too file changing. I try to use optiboot, but the ATMEGA328 isn’t listed.
