# Examples using bootloader
Example for STM32F3 demonstrating the bootloader. The example consists of application binaries, 'a'
which allows you to press a button to start the DFU process, and 'b' which is the updated
application.
## Prerequisites
* `cargo-binutils`
* `cargo-flash`
* `embassy-boot-stm32`
## Usage
```
# Flash bootloader
cargo flash --manifest-path ../../../embassy-boot/stm32/Cargo.toml --release --features embassy-stm32/stm32f303re --chip STM32F303RETx
# Build 'b'
cargo build --release --bin b
# Generate binary for 'b'
cargo objcopy --release --bin b -- -O binary b.bin
```
# Flash `a` (which includes b.bin)
```
cargo flash --release --bin a --chip STM32F303RETx
```
