Hi,

I have an arduino board (ATmega1280). The board works well before I change it from one place to another. Now the following error is showed when I upload a program (and it's uploaded to the board):

avrdude: verification error, first missmatch at byte 0x0482
0x64 != 0xc8
avrdude: verification error; content missmatch


What does it mean?

Thanks

I think that means there is a bad byte in the flash memory that isn't programming correctly.  Double check your hardware configuration (especially supply voltage) and try again - there are other reasons it could fail including unreliable connections between computer and Arduino.
