I have a very bad issue. I have a project due in a few days and i've just hit the worst problem ever.
I need to run my ATmega off of 3.7 volts but I can't burn the Arduino Pro Mini bootloader onto the chip. The pro mini bootloader runs at 3.3v at 8mhz so how can I get it on there without avrdude being all like, yo invalid device signature, double check or type -F to override.
I can't find any place to type in -F to override this error.
Sounds like you are trying to program a 329-PU. Check the part number you are trying to program, if that is the case do a search on the forum for "328-PU" for the fix.
I'm using an Arduino that has an Atmega328p with the ArduinoISP program on it and I'm trying to burn a bootloader on to an atmega328p, which is on the breadboard, that is meant for an Arduino pro mini w/ Atmega328p 3.3v at 8MHz.
How would get that bootloader on to the atmega328p. I have been told to edit the hex file( bootloader) to changed the expected device signature that the bootloader is looking for. My issue with that is that I can't figure out where I need to place the device signature in the hex file.
