Hello, I am trying to upload the DCC++ project to ATMega 2560. From W10 via Arduino software, but it writes this error message: avrdude: verification error, first mismatch at byte 0x136c 0xb8 != 0xf8 I didn´t find anything about this error message... Could give me any advice?

Is your board properly recognised in Windows device manager?
Have you tried another cable?
