Uploading with uno get:

Code: [Select]
Binary sketch size: 11,852 bytes (of a 32,256 byte maximum)
avrdude: verification error, first mismatch at byte 0x0002
         0x6a != 0x61
avrdude: verification error; content mismatch

Using another uno does not give error. uploads fine. this uno does not upload. gives error above.

Do you have any wires plugged into it?


Nick Gammon

Is this a genuine Uno? Where did you buy it?

James C4S

Does a smaller sketch upload?  How old is it?  As Nick already asked, where'd you get it?

Could be the flash on the ATmega has failed.
