# Examples using bootloader
|
|
|
|
Example for Raspberry Pi Pico demonstrating the bootloader. The example consists of application binaries, 'a'
|
|
which waits for 5 seconds before flashing the 'b' binary, which blinks the LED.
|
|
|
|
NOTE: 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.
|
|
|
|
## Prerequisites
|
|
|
|
* `cargo-binutils`
|
|
* `cargo-flash`
|
|
* `embassy-boot-rp`
|
|
|
|
## Usage
|
|
|
|
```
|
|
# Flash bootloader
|
|
cargo flash --manifest-path ../../bootloader/rp/Cargo.toml --release --chip RP2040
|
|
|
|
# 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 RP2040
|
|
```
