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?
yes, I tried 3 more cables and my computer recognized the device because I installed the CH341 driver, already when I started to flash the ESP8266 chip... the device loads the software into the device for a few seconds everything flashes and then writes an error.
Please include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.
In the Tools, Board menu, what have you selected?
Arduino: 1.8.16 (Windows 10), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"
