### Via dfu-util
2+
3+
This board can programmed via DFU bootloader, using e.g. [dfu-util](http://dfu-util.sourceforge.net/). To enter the DFU bootloader, double tap the reset (blue) button, or you can use `machine.bootloader()` from the MicroPython REPL.
4+
5+
```bash
6+
dfu-util -w -d 2341:035b -a 0 -d 0x8040000 -D firmware.dfu
7+
```
8+
9+
Or from Micropython source repository:
10+
11+
```bash
12+
make BOARD=ARDUINO_PORTENTA_H7 deploy
13+
```
