Bonjour,
J'essai difficilement de configurer un bootloader pour pouvoir charger mon prog via USB.
J'utilise donc un prog bootloader qui fonctionnait déjà avec un autre programme fait antérieurement, ou je chargeai donc ce programme puis chargeais le .hex du programme principal.
Pour ça, j'ai donc adapter les zones mémoires, tant sur le prog bootloader et le prog principal dans les fichiers linker.
Actuellement, mon prog bootloader ce charge bien et je boot bien dessus pour charger mon prog principal, seulement une fois charger,mon nouveau programme principal ne tourne pas.
ce qui est bizarre, c'est que mon nouveau programme n'utilise pas de fichier linker btl_mx.ld et quand j'ajoute donc ce fichier j'ai un packet d'erreur à la compilation alors que si je le retire du projet, tout tourne bien.
Je programme sous mplab x ide v3.26 sous harmony et implémente une stack ethernet
