Hi Arduino experts out there,

I'm trying to bootload an ATMEGA 328P-AU using a USBasp programmer (wireing see attached picture).
The IDE version: Arduino 1.8.10
What I get is the above mentioned error message.

Please see the attached log file I get trying to burn the bootloader.

Thanks in advance for any help!

Is this a standalone m328p, or is it part of a beelogger? If you have a SD card inserted, remove it and try again.

It is part of a beelogger, but no SD card no SIM modul and nothing else inserted. Just the main PCB with nothing else plugged on except the USBasp of course.

Are you using an Arduino Nano or a Pro Mini? The beelogger I googled was using a Nano. You might try MiniCore. It gives you more options.
