Hello, with avrdudess I installed optiboot_atmega328-Mini.hex on atmga328p and now My chip doesn't response... Before that fuses was these: -U lfuse:w:0x62:m -U hfuse:w:0xd9:m -U efuse:w:0xff:m . I tried with 8 Mhz, 16 Mhz crystal, no crystal, and I still get this error:
avrdude: warning: cannot set sck period. please check for usbasp firmware update.
avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
Mabye someone know what happened and How to fix it?
