Fusebity
Bootloader działa poprawnie bo mikrokontroler jest wykrywany i da się załadować hex do pamięci.
Niestety hex się nie wykonuje i nie wiem co jest nie tak. Hex wgrany przez programator działa poprawnie.
Code:
void setup() {
pinMode(13, OUTPUT);
digitalWrite(13, LOW);//test
}
void loop() {
digitalWrite(13, LOW);//test
delay(500);
digitalWrite(13, HIGH);//test
delay(500);
}
pinMode(13, OUTPUT);
digitalWrite(13, LOW);//test
}
void loop() {
digitalWrite(13, LOW);//test
delay(500);
digitalWrite(13, HIGH);//test
delay(500);
}
Jak widać mój program testowy to najzwyklejszy blink.
Próbowałem różnych ustawień fusebitów ale nic nie pomogło.

; The above 8 lines can be changed and buid a bootloader for the desired frequency

Ma ktoś jakiś pomysł co jeszcze można z tym zrobić?
