## Backing Up the Firmware

Watch the video below for detailed instructions on the whole process. It is recommended to take the time to make a backup of the firmware currently installed on the board, in case you decide you want to go back to the factory-installed version.

## Flashing the Firmware

### 1. Build Marlin

Use these example config files (adjusted to your needs) and build Marlin as usual.

### 2. Prepare the Board

- **Turn off the printer and disconnect AC power.**
- **SW1** routes power to the board from the USB port or from an external 24V source.
   Move jumper **SW1** to **USB**.
- **JP1** is connected to the **BOOT0** pin which blocks programming.
   Remove the **JP1** jumper.

### 3. Get STM32 Flasher

Download the _STM32 Flasher_ software at the ST Micro [download page](https://www.st.com/en/development-tools/flasher-stm32.html#get-software). Use _STM32 Flasher_ to flash your Marlin binary file to the board following the procedure shown in the video.

### 4. Final Steps

- Put the **SW1** and **JP1** jumpers back in their original positions.
- That's it!

## Restoring from Backup
 - If you made the backup as described in the video just flash that file to restore the firmware to its previous state.
