The source code can be adapted for other, more modern devices. it is written for use on a Tiny12 and it uses an old 90S1200 to run. There is a reset disable fuse deprogrammer project available on the web listed under 'Cappells' AVR website. ![]() What programmer are you using to read the fuse settings? Could it be giving you a wrong reading or maybe it is being interpreted incorrectly? how the fuse got programmed for ResetDisable. It would be important to determine how this happened, ie. especially with the SOIC package and especially if the chip is on a PCB. Once this fuse byte is reprogrammed to reestablish the Reset pin to normal operation, then the standard ISP (in circuit programming) methods can be used again. It's not necessary to program the entire Flash only the Fuse byte that holds the RESETDISABLE fuse. ![]() High voltage being a +12 volt level that is switched onto the Reset Pin during programming. It will be necessary to change this fuse with a 'high voltage' programmer. ![]()
