Burning bootloader - wrong signature

Hi all,

I've been working through the various examples/documents on burning the bootloader and I am still stuck. I have used the breadboard configuration and al the various flavors, but when I try to burn the bootloader, it comes back with the wrong signature. I'm using an Arduino Uno R3, and the 1.8.19 Arduino IDE, Arduino as IDE programmer.

Any advice greatly appreciated!

I had it wired right but had a bum USB cable. Had to dig in boxes to find another A/B male cable. Have not used one in many years but Arduino likes 12-year-old tech...

Your Programmer Type is most likely wrong... it should be listed as arduinoisp in the command line if you're using the Arduino to do it.

What does the command line you're using look like?

Turned out to be a bad USB cable! Spent a lot of time digging into what could be wrong, and I stepped back and thought "Gee, try another cable". Bingo!

Strange as I could write to the Arduino uno but had no communication with the 3DC.

I did nothing else but re-run the command line to read the 3CD and it read back perfectly. New firmware installed after burning the bootloader of course.
