Discussion Overview

The discussion revolves around issues faced by a user attempting to activate an Arduino Mega 2560 board, specifically related to serial communication errors during the upload process. The scope includes troubleshooting technical problems with hardware and software configurations.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant reports an error message indicating that the Arduino Mega 2560 boards cannot communicate over the specified COM port, despite verifying the setup and using a working Arduino Uno.
  • Another participant suggests that the issue may be related to a driver problem, specifically the need for a CH340 driver for Windows to communicate with the AZDelivery boards.
  • A question is posed regarding the ability to get the boards working through the Arduino IDE and the specific command being used for AVRDUDE.
  • The original poster indicates that the CH340 driver is recognized but expresses frustration after trying various solutions and mentions acquiring an original board instead of a clone.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the cause of the issue, with differing opinions on whether it is a driver problem or something else. The discussion remains unresolved regarding the specific solution to the communication error.

Contextual Notes

Limitations include the lack of detailed information about the specific setup and configurations used by the original poster, as well as the potential dependency on the correct installation of drivers for proper functionality.

Failure to be able to activate Arduino Mega 2650
hi; i purchased 3 of these,

AZDelivery 3 x AZ-MEGA2560-Board Bundle with Prototype Shield​

and each is reporting the error message below.

I have triple checked every aspect of the set up and all seems in order, cable devices port, board reburn bootloader et al . I have substituted an arduino uno and it works fine; could you help please
Thanks
Martyn

Technology news on Phys.org
It’s likely an upload/serial-port error on Windows, not a code problem. In plain English, AVRDUDE can’t talk to the board over COM3.

You might need a windows CH340 driver to talk to the card. Apparently AZ cards need that to interact with Windows.

There are other possible issues too. You should be able to find help on Arduino forums. I don’t think many members here work with these devices.
 
Can you get the boards working through the Arduino IDE?
What command are you using for AVRDUDE?
 
thanks, it is viewing the CH340; I've pretty much tried everything; giving up now; have acquired original - v - clone
Thanks
Martyn
