Hi,
i've been trying to upload a sketch to my arduino Uno and avrdude give me an error every time
avrdude: verification error, first mismatch at byte 0x7800
0x05 != 0xff
avrdude: verification error; content mismatch
i tried to upload the sketch on my mega board and its working fine no problem. My sketch is pretty big for a uno board (31 506 bytes out of 32 256) is it why avrdude is giving me this error ?
