# Examples using bootloader
|
|
|
|
Example for STM32L4 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/stm32l475vg --chip STM32L475VG
|
|
# 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)
|
|
