Hi, i bought a new Melzi board as a replacement for the original one, i had no problems flashing the bootloader trough SPI and no problems running some test code (i wrote a simple code to turn on and off a pin and checked it with the oscilloscope, so the micro is indeed kind of working and the code uploads fine). My issue starts after the firmware is uploaded , i get nothing on the LCD and the "debug" LED is constantly on. I downloaded this firmware from Github (https://github.com/dennistimmermann/tronxy-x1_repetier) already configured for the Tronxy X1, but i'm wondering if maybe it have the wrong pinout for my specific board.
