Topic: Nano avrdude (Read 307 times) previous topic - next topic


Hi guys,
i was working on my arduino project to school and everythink was working. Then i changed few cables and arduino won´t upload my code.

This is what i get every time i try it to uplouded.
avrdude: verification error, first mismatch at byte 0x0000
         0xff != 0x0c
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch

Do you know what to do to fix it?


If you disconnect all external wiring, circuitry, and components from your Nano, does the problem still occur?



Sometimes re-burning the Bootloader will fix that problem. Maybe you could find someone, classmate/instructor, who could help you re-burn the Bootoader? You would need either an ISP programmer or an Arduino used as "Arduino as ISP" to do this.
