| # Examples using bootloader
 | |
| 
 | |
| Example for nRF52 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-nrf`
 | |
| 
 | |
| ## Usage
 | |
| 
 | |
| 
 | |
| 
 | |
| ```
 | |
| # Use bare metal linker script
 | |
| cp memory-bl.x ../../bootloader/nrf/memory.x
 | |
| 
 | |
| # Flash bootloader
 | |
| cargo flash --manifest-path ../../bootloader/nrf/Cargo.toml --features embassy-nrf/nrf52840 --release --chip nRF52840_xxAA
 | |
| # 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 nRF52840_xxAA
 | |
| ```
