### WeAct Studio STM32H7xx
2+
3+
WeAct Studio make a number of STM32H7xx-based boards, they can all be updated
4+
using
5+
[DFU](https://en.wikipedia.org/wiki/USB?useskin=vector#Device_Firmware_Upgrade_mechanism).
6+
7+
### DFU update
8+
9+
Hold the Boot button - the middle of the cluster of three buttons - while the
10+
board is reset (either by connecting USB or by pressing reset). Release the Boot
11+
button shortly after the board has reset. The board ought to now be in DFU mode
12+
and detectable as such from a connected computer.
13+
14+
Use a tool like [`dfu-util`](https://dfu-util.sourceforge.net/) to update the
15+
firmware:
16+
17+
```bash
18+
dfu-util --alt 0 -D firmware.dfu
19+
```
