Overview

mDBG debugger, please see explained yourself on the hackaday website for details.

Manual welding is highly not recommended as it is time-consuming and error-prone, and it is very troublesome to find hardware faults; it is recommended to use Jialichuang SMD patch service.

You'll need Atmel Studio.

For new board goto 1a, and for reprogramming goto 1b.

1a. Connect Xplained Yourself board to USB, Atmel Studio should show new tool (View>Available Atmel Tools): Atmel Mega DFU. (if not goto 1b and check continuity in your board).

1b. Turn bootloader on by: press HWB button, press RST button, release RST, wait few seconds, release HWB.

2. Go into programming mode (RMB click on DFU), Select ATmega 32U4, and read signature.

3. Program Flash and EEPROM (in Memories tab) with the same protocol.

4. Reset board with RST button.

5. Here's your fresh, new debugger!
