[SOLVED] Seemingly random error messages when uploading
Friis Nielsen Fredrik 2016-07-27 18:39:12 3217 Views4 Replies Hi.
I'm working on a project based on the Bluno MEGA 2560.
My problem is that I keep getting random error messages when uploading, no matter what sketch I try, including the "Blink" example. I am using cable when uploading.
Here is a list of the error messages I got from hitting the upload button five consecutive times without changing anything. (the "attempt #X" is not part of the error, I included it to make it easier to read)
Attempt #1 Unsuccessful
avrdude: verification error, first mismatch at byte 0x03b2
0x63 != 0xc7
avrdude: verification error; content mismatch
Attempt #2 Successful upload
Attempt #3 Unsuccessful
avrdude: verification error, first mismatch at byte 0x1fb1
0x0f != 0xc0
avrdude: verification error; content mismatch
Attempt #4 Unsuccessful
avrdude: verification error, first mismatch at byte 0x01b1
0x00 != 0x02
avrdude: verification error; content mismatch
Attempt #5 Unsuccessful
avrdude: verification error, first mismatch at byte 0x12b1
0xe0 != 0xe8
avrdude: verification error; content mismatch
As you can see, the error messages change every time, making this very hard to search online for.
In my hours of troubleshooting I have tried:
Rebooting PC
Uploading from different PC
Connect arduino to another USB port
Removing ALL wires and shields
Checking that the correct COM port is selected
Checking that correct board and processor is selected
Different IDEs tried, 1.6.5, 1.6.8 and 1.6.9.
I have tried asking the arduino forum, but they could not find a soulution.

My knowledge comes up short on this one.
All suggestions are welcome.
Thank you.

I applied for an RMA and sent it back to dfrobot. It turned out to be faulty.
Thanks again to the dfrobot team. Friis Nielsen Fredrik

I havent met this kind of problem before and I guess its very posslible to be a BLE chip problem, maybe you can refer to this link for repair: How to flash a new CC2540 chip with DFRobot BLE service?
Of course, if you bought the Bluno Mega2560 in DFRobot, you could go to Product Returns page to request an RMA number for a replacement and wait for our store to deal with the request.
Have a good time.
