I destroyed atmega chip?

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? :confused:

Thank's god It started to work with 15Mhz crystal :slight_smile:

I don’t think 15Mhz crystal is key to solve the problem. If the chip can run with external crystal 15MHz, it also would run with external crystal 8 Mhz and 16 Mhz for sure. Maybe your problem is related to connection, capacitors making not stable.
