I have an Atmega328p on a board that I want to program using an Arduino programmer. I've got the programmer working to program other Arduino's over ICSP header, but when trying to use the same settings to avrdude to read/set the fuses of the bare MCU with oscillator I get the following:

❯❯❯ avrdude -v -p atmega328p -b 19200 -P /dev/cu.wchusbserial213240 -c stk500v1 ⏎ master

 Double check connections and try again, or use -F to override
 this check.
avrdude done. Thank you.

I've checked the soldering as good as I can and it seems to be right. I have a 10K pullup on reset, an oscillator with caps. I'm suspecting I might have fried the MCU when soldering or something - is there anything simple I can check?

  • All PWR connections check out
  • I've checked the oscillator with a scope and it isn't oscillating, but I'm thinking that is normal since it's a bare chip that I'm trying to set the fuses to use the external crystal? The oscillator is at least connected correctly.

  • Try using the "burn bootloader" function inside the IDE. That also sets the fuses. Commented Jan 11, 2018 at 18:39
  • I've done that too. The first thing that menu item does though is actually calling avrdude just like that - I think I actually looked at the verbose log in the IDE to get the params right. Commented Jan 11, 2018 at 21:35

It turned out it was a bit of bad soldering on the MCU. This same msg you'll get if just leaving the ICSP floating.

  • I'm glad you found a solution, but could you accept this (your own) answer as the solution? This question just got bumped to the frontpage and actually is already solved. Commented Mar 18, 2018 at 16:38
