I have some old hardware which uses an AT90S8515, I also have two .hex files, one for flash the other for EEPROM. My problem is I can't find a way to program the old hardware with these .hex files. I have a JTAGICE3 programmer and have downloaded the latest studio6.2 software, but that is where it stops. Can anyone tell is it possible to achieve what I want with the tools that I have and if so what are the steps? If not, then does anyone know what I need?
