Is it possible a sketch can be loaded to an Uno but not Nano

Development Tools Uploading

Hi, I am using a sketch that loads on an Uno but not a Nano. I have not encountered this before. The message reads
"avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x6e
I am no expert but cannot see anything in the sketch that may be causing this.

  • If there are zero hardware issues, the sketch on both the UNO and NANO should work.

The Nano comes in a few flavours. You have a choice under tools / processor between 328P, 328P (old boot loader) and 168.

Thanks, the problem has been solved. Now to get the LCD monitor going. Smile.

It would help others reading this thread if you said what you did wrong when you first tried and after you got the knowlage that it should work.

As it stands it makes it look that @LarryD did a sort of "faith healing process". I know he is good, but not that good surely? :wink:

Thanks Grumpy :grinning:
What I did was to disconnect all the pins to the Nano and it loaded. I then reattached the pins. I have had to do this on many projects before and not sure why I did not think to do it this time.
In essence he was correct. What works on an Uno works on a Nano, I guess.

You had something connected to pin 0 or pin 1? Or the RST pin?
