Topic: Arduino Mega 2560 Bootloader issues (Read 778 times) previous topic - next topic



I have got a Arduino Mega 2560 and I am having difficulty uploading sketches to it, the uploading seems to be a bit erratic where after compiling and if I do a reset on the Mega board the upload is fine, else it times out.

I have tried the following:-

I am using the latest Arduino 1.0.2

1. Reflash the bootloader hex from the Arduino folder using  AVRISPmkII via AVR Studio 6
2. Rest board and PIN13 LED blinks upon boot
3. Send 3 !!! via a terminal client and the serial monitor shows up
4. Verified that the programming protocol is set to wiring in Arduino software

Despite these, when I try to use the Ardunino software to program the Mega board using USB cable, it timeouts and only programs if I manage to press the reset button on a specific time.

Any ideas whats going wrong? Could someone point me in the right direction to resolve this?
