Problem flashing Marlin onto Melzi board.

Problem flashing Marlin onto Melzi board.

Hi,

I have a Tronxy P802ma printer with a Melzi V.3.0 board.

I used Arduino IDE to flash a Tronxy Master Firmware for Marlin onto the Melzi. I set the USB jumper correctly and flashed the firmware over USB cable.

For a while the printer would boot just fine and the LCD display would illustrate that it was loading the Marlin firmware. The menus seemed to work, giving options such as auto levelling etc.

Albeit, after some time the display has started showing signs of a problem. Sometimes the display shows garbled characters and doesn't respond and sometimes the printer seems to go into a boot loop. Pronterface won't connect and Repetier Host is intermittent with its connection too.

I've tried to re flash the firmware again, but now I get the AVRdude out of sync error everytime. The board LED flashes red, but I can't seem to get anywhere at all.

Does anybody have any advice please? Starting to find this stressful! Haha!

Many thanks, Billy.
