1# Examples using bootloader
2
3Example for Raspberry Pi Pico demonstrating the bootloader. The example consists of application binaries, 'a'
4which waits for 5 seconds before flashing the 'b' binary, which blinks the LED.
5
6NOTE: The 'b' binary does not mark the new binary as active, so if you reset the device, it will roll back to the 'a' binary before automatically updating it again.
7
8## Prerequisites
9
10* `cargo-binutils`
11* `cargo-flash`
12* `embassy-boot-rp`
13
14## Usage
15
16```
17# Flash bootloader
18cargo flash --manifest-path ../../bootloader/rp/Cargo.toml --release --chip RP2040
19
20# Build 'b'
21cargo build --release --bin b
22
23# Generate binary for 'b'
24cargo objcopy --release --bin b -- -O binary b.bin
25
26# Flash `a` (which includes b.bin)
27cargo flash --release --bin a --chip RP2040
28```
