1# embassy-boot-rp
2
3An [Embassy](https://embassy.dev) project.
4
5An adaptation of `embassy-boot` for RP2040.
6
7NOTE: The applications using this bootloader should not link with the `link-rp.x` linker script.
8
9## Features
10
11* Configure bootloader partitions based on linker script.
12* Load applications from active partition.
