Hello there, I tried to bootload an atmega 88v using arduino uno3, but I got the following message:
Error: invalid device signature
Error: expected signature for ATmega88 is 1E 93 0A
I use Arduino IDE 2.3.3 (Win11).
This usually means that either the connections are not correct or you have not selected the proper programmer.
Upload the ArduinoISP sketch to the UNO (File->Examples->ArduinoISP->ArduinoISP
make the recommended connections from the comments
select the correct programmer
Tools->Programmer->Arduino as ISP (not ArduinoISP !!)
and try again. What device signature was found ?
I try that now, but the exact same error code was output.
Not sure if this helps, but here's a screenshot of the bootloader being burned.
Additional error code details.

Device signature = 00 00 00 (retrying)
Device signature = 00 00 00 (retrying)
Device signature = 00 00 00
Error: invalid device signature
Error: expected signature for ATmega88 is 1E 93 0A
- double check connections and try again, or use -F to carry on regardless
Avrdude done. Thank you.
Failed chip erase: uploading error: exit status 1
If the device signature is 00, that usually means there is a bad connection somewhere (or an incorrect one)
Can you post the way you have connected them together ? (and check all connections with a DMM, there could also be a bad jumper cable)
