Hello, I'm would like to know if the fuses are the same if I want to flash an atmega328 without bootloader.? low_fuses=0xFF high_fuses=0xDA extended_fuses=0x05 ??? And the lockbit I dont have to set, right? Thanky You very much short notice! Sibylle

ok, I have tried now to upad the bootloader - but still I'm getting just error messages; is there probably a problem between avrdude and old stk500 and new atmega328???

avrdude: successfully opened stk500v1 device -- please use -c stk500v1 avrdude: Expected signature for ATMEGA328P is 1E 95 0F Double check chip, or use -F to override this check. and Im looking for where I could make this changes proposed by avrdude....making -c stk500v1 instead of -c stk500...??? Thanx for any help, suggestions etc. and hope not to annoy you all. sibylle
