Electronic – arduino – ATMEGA328p-AU BootLoader

arduinoatmegaatmega328pbootloader

I have ATMEGA328P-AU chip, to burn the bootloader I used ARDUINO Uno Board as "ARDUINO as ISP" with setup Board: Nanno. I'm getting the following error. While looking for the solution I got suggestions of

  1. rechecking the connection – Yes I did
  2. Lower the Buad Rate – Tried observed the same result as below
  3. Tried varying the external oscillator 8MHz/ 16Mhz
    The command to upload the bootloader is as follow:

D:\WorkSpace\Arduino\arduino-1.8.7\hardware\tools\avr/bin/avrdude -CD:\WorkSpace\Arduino\arduino-1.8.7\hardware\tools\avr/etc/avrdude.conf -v -patmega328p -carduino -PCOM9 -b19200 -e -Ulock:w:0x3F:m -Uefuse:w:0xFD:m -Uhfuse:w:0xDA:m -Ulfuse:w:0xFF:m

I want to know the does this signature 0xffffff indicates I have blown out the IC similar ???

Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check. avrdude done. Thank you.

After trying a lot of time on the bootload uploading using Arduino as an ISP, I switched to USBASP. And successfully uploaded the code on those suspicious IC, which I kept aside considering dead. Though I could not figure out the fault in Arduino while uploading, I would suggest doing the same if someone stumbled at a similar question.
