ARDUINO - Grabar el boot loader
El otro día me llegaron dos Atmega328, los había pedido para colocarlos en el arduino. El caso es que venían sin el cargador de arduino, normal si son nuevos. ¿Como grabar el boot loader en el Atmega328?. Tengo varios grabadores de ATMEGA, entre ellos uno conectado al USB llamado usbasp de la página:http://www.fischl.de/usbasp/
Este montaje lo he construido yo también, y mis experiencias las comente hace unos años en mi página:
http://seta43.duckdns.org/miATp.html
Como la versión que tengo de Arduino IDE no soporta mi grabador usbasp he tenido que buscar gente que le pasa lo mismo y encontré la página:
http://wolfpaulus.com/tag/atmega168
Explica bastante bien los comandos que tienes que dar al avrdude para grabar el boot loader.
Yo los he cambiado para que me sirvan al mio y aquí los expongo.
avrdude -p m328p -c usbasp -V -e -U lock:w:0x3F:m -U hfuse:w:0xD8:m -U lfuse:w:0xFF:m -U efuse:w:0x03:m
avrdude -p m328p -c usbasp -V -D -U flash:w:ATmegaBOOT_168_atmega328.hex:i
avrdude -p m328p -c usbasp -V -U lock:w:0x0F:m
También expongo el resultado de la consola de avrdude.
