Error "avrdude: stk500_recv(): ....." after bootloader upload (Arnuino Nano)

Hi,

I've had problems with my Arduino Nano of the type:

"avrdude: verification error, first mismatch at byte 0x0006 0xXc != 0xXX (I used capital X as I didn't remember the exact adress)
avrdude: verification error; content mismatch"

So I used the bootloader programmer I found on this forum to upload a new version of the bootloader on my Nano, with an Arduino Uno.
It seemed that the upload worked OK, but when I now try to upload a script to my Nano, I get a different error:

"avrdude: stk500_recv(): programmer is not responding"

I am pretty new to microcontroller programing, don't know what to do.

I'd be grateful if you could provide some help,

Best

Aurel

Hey Nick, maybe make it so that any post mentioning Arduino just gets blocked? :)

Yes, good idea. Although some people don't know how to spell "Arduino".

I've made a preliminary stab at it. I may have to update the regexp to include words like "microcontroller" etc. We'll see how it goes.
