mi raccomando fai tutto a radio spenta lascia alimentare il processore dall'usbasp:
avrdude.exe -c usbasp -p m128 -P usb -B 100 -u -U lfuse:w:0x3F:m -U hfuse:w:0x89:m -U efuse:w:0xFF:m
una volta impostati stacca la radio dall'usbasp riattaccala e flashagli il firmware, mi raccomando la versione per 128 |
Ma che diavolo!
1)Prova di lettura effettuata correttamente con il comando
avrdude.exe -c usbasp -p m128 -U flash:r:C:/Users/Nitro/Desktop/Modifica firmware Trasmittente/da canc.bin:r
stacco e riattacco usbasp
2)Set dei fuses con il comando
avrdude.exe -c usbasp -p m128 -P usb -B 100 -u -U lfuse:w:0x3F:m -U hfuse:w:0x89:m -U efuse:w:0xFF:m

Ovviamente anche la prova di scittura ha dato lo stesso esito.
Un' altro processore bruciato? Non posso andare avanti così!
eepe setta sempre lfuse:w:0x0E mentre tu lo metti lfuse:w:0x3F. Può essere questo il problema?
Che devo fare adesso per recuperarlo? Acquistare un oscillatore esterno? Usare l'opzione -F per settare i fuse?
UFFAAAAAAAAAAAAAAAAAA!
