Issue in boot loading nano clone

Using Arduino Avrdude, stk500, Bootloader issues
1

Hi all ,,

i am a newbie ,i had made an arrangement for controlling my room humidity using nano clone and was working perfectly for last 6 months. but suddenly the nano stopped working and i replaced with a new one but in the same day evening the new one also stopped working. Both of them are showing the same issue, when connected the power led is turning on but does not able to detect sketch and cannot upload any sketch. After googling about the problem i tried to burn the bootloader using my uno clone but both off them shows error during the boot loading .

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

Error while burning bootloader."

The above message is always showing , i checked the connections but find it is okay.

Pls help me to know the issue what i am facing.

Please do this:

  • File > Preferences > Show verbose output during: > compilation (uncheck) > upload (check) > OK
  • Tools > Burn Bootloader
  • After the process fails you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
  • Paste the error messages in a reply here USING CODE TAGS (</> button on the toolbar).
