# Kakute F7 Mini V3

Kaptan support for the Holybro Kakute F7 Mini V3.

The checked-in manufacturer manual is [Holybro_KakuteF7_Mini_V3_Manual_v1.0.pdf](Holybro_KakuteF7_Mini_V3_Manual_v1.0.pdf).

## Build

Build the firmware from the workspace root:

```sh
cargo build --release -p kaptan-kakute-f7-mini-v3 --features firmware --target thumbv7em-none-eabihf
```

Create its DFU (device firmware update) image:

```sh
./scripts/create-dfu-image.sh \
  target/thumbv7em-none-eabihf/release/kaptan-kakute-f7-mini-v3 \
  target/thumbv7em-none-eabihf/release/kaptan-kakute-f7-mini-v3.bin
```

The converter works with any firmware ELF. It uses rustup's `llvm-tools-preview` component which the workspace toolchain installs automatically.

## Flash over USB DFU

1. Disconnect the board from USB.
2. Hold the `Boot` button.
3. Connect USB, then release `Boot`. The board should enumerate as STM32 DFU.
4. Flash the generated image:

```sh
dfu-util --alt 0 --dfuse-address 0x08000000:leave --download target/thumbv7em-none-eabihf/release/kaptan-kakute-f7-mini-v3.bin
```
