Bonjour,
J'ai parcouru plusieurs sujets du forum et essayer plusieurs choses, mais je n'arrive toujours pas a changer le bootloader sur un arduino nano. J'ai un mega 2560 et un autre arduino nano, mais les deux me font la même chose. J'ai essayé l’histoire des condensateurs et le -F mais rien n'y fait.
Je souhaites changer ce bootloader car je veux pouvoir utiliser le Watchdog.
Vous trouverez ci dessous la copie du debug
Je vous remercie d'avance pour votre aide et ou conseils
