#### Goals

- demystify the LPC55 ROM bootloader (at least for people who know Rust), by 
  - modeling "protected flash" settings and other sparsely documented data as Rust types
  - implementing its protocol, removing leftover details for older chips
  - clarifying the cryptographic details
- unify
  - NXP's `elftosb`, `blhost` and `spsdk` projects
  - molejar's `pyMBoot`
  - ergonomic corresponding TOML-based config files
- library-first (independent of CLI), and an HTTP interface
- support for non-file based signing keys (via PKCS #11 URIs)

#### Installation

`cargo install --locked`

Examples:

- `lpc55 info`
- `lpc55 reboot`

Examples from inside repository (which includes example binaries, certificates, configurations):

- `lpc55 fingerprint-certificates example-cfgs/example-cfg.toml`
- `lpc55 sign-fw example-cfgs/example-cfg.toml`
- `lpc55 assemble-sb example-cfgs/example-cfg.toml`
