Hi,
I managed to get my Pro Mini in an endless loop after messing with the watchdog.
I was glad to find Nick Gammon's programmer which loaded the 16 MHz Optiboot loader (UNO) to the mini apparently successful. Unfortunately, I got the usual sync error when uploading my sketch.
I thought to use the option to use the Lilypad (8 MHz) bootloader. With this one I can upload my sketch, and its working (1/2 the speed obviously).
I cant find any differences that would cause this to work on 8 and not on 16 MHz although some of the Fuses are different but don't explain the problem as far as I can see. Fuse settings attached.
Anybody any good ideas?
Thx, Harry
