I have been trying unsuccessfully for some time now to use my Mega2560 with no luck. While the Arduino IDE can see it as can my Windows 64-bit Device Manager on the correct Com Port, regardless of what sketch I try to upload, something as simple as Blink results in the timeout message. Here are the items I have attempted all with no success.
- Uploaded Blink and other sketches to a known, working UNO. This thereby rules out the USB cable, the USB port and Windows recognition of an Arduino device.
- Followed Nick Gammon's website to the T using the Uno as the device with the sketch in an attempt to flash the Mega2560. It worked once and now no longer works, resulting in a loop as can be seen below. This loop only occurs when the Reset pin on the programming Uno is connected to its own D10 pin as instructed on the website. This can be seen in one of the attachments
- Placed the board into DFU mode and followed other directions to utilize Flip 3.4.7 to communicate with the Atmega16u2 chip and installed the most recent .hex located within the Arduino 1.6.4 repository. This interestingly enough is the only action that gets the TX light on the board to turn on and stay on. Once clicking start application the TX light goes out never to come on again.
I have also uploaded the output from the Arduino IDE at it pertains to the timeout. I did read online posts regarding issues with code where there were three !!! characters, of course Blink does not have that so I know that is not the issue either.
Looking for some assistance and any ideas so I can start programming with my new board!
