I'm getting this error when I try to upload any code to a specific board, using Wiring 0022 or 0027

The model is AC-03 0309

avrdude: reading on-chip flash data:
avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0000
         0x0c != 0x14
avrdude: verification error; content mismatch

avrdude done.  Thank you.

I tried with other boards and they worked well.

There's anything I can do in this case?

hola Juan Carlos, I've seen this kind of problem after a high voltage problem or wrong motors with higher voltage connections etc, the board should be fine but you need to re-flash the bootloader.
The bootloader files are here: http://wiring.uniandes.edu.co/source/trunk/wiring/bootloader/ download the latest revision for the atmega128stk500boot.hex I am guessing you have rev 0004 right? Do you have an AVRISP programmer at hand? http://www.atmel.com/dyn/products/tools_card.asp?tool_id=2726
