Tengo este prototipo de PCB con un atmel avr atmega328p y no responde correctamente a mi AVRISP Mk2. Por lo que puedo decir, la firma es incorrecta para esa parte.
Aquí está la salida de avrdude:
[masterkraft0r@Masterkraft0r-HP14 ~]$ avrdude -p atmega328p -c avrisp2 -vvvv -F

avrdude done. Thank you.
Lo interesante es que cuando hago esto varias veces seguidas, los últimos 4 dígitos de la firma del dispositivo siempre son diferentes.
Lo que ya he hecho:
- bajando el bitclock con -B; no tuvo efecto
- verificó todas las conexiones; son correctos.
- verificó todos los voltajes; también correcto
- el dispositivo es nuevo, por lo que no puede ser un problema de fusibles;
- agregó un pullup (10k) en la línea de reinicio; sigue sin funcionar
- bomba de carga + microcontrolador = 1mA (ver esquema)
- el programador trabaja y mide 3V3; fue probado con una placa diferente, el mismo mcu
Actualizaré esta lista con las cosas que probé
¿Alguien tiene una idea de lo que está pasando aquí?
