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

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,

Template:Arduino Please post Arduino-related questions to the Arduino Forum or to StackExchange: Arduino. This saves splitting questions and answers between this forum and the Arduino ones.

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.
