## Flashing the device ## Flashing the device
The device comes with a bootloader that allows flashing via `dfu-util`. The device comes with a bootloader that allows flashing via `dfu-util`.
There are two buttons on the board labeled `BOOT0` and `NRST`. If RIOT is already running on the board, you can upload your RIOT-firmware by typing
- Press and hold down `NRST` to reset the CPU
- Press `BOOT0` while keeping `NRST` held down
- Release `NRST`, afterwards release `BOOT0`
The board will now show up as `0483:df11` - `STM32 BOOTLOADER` and will accept
firmware using the DFU protocol.
You can upload your RIOT-firmware by typing
``` ```
make BOARD=weact-f411ce flash make BOARD=weact-f411ce flash
``` ```
RIOT will make sure to enter the bootloader automatically.
If RIOT crashed or you have the plain board with the stock firmware, you have to enter
the bootloader manually.
