Host-side library to interact with and provision NXP LPC55 devices.
Additionally, a command-line tool
lpc55 is implemented, so far
it can list all properties via
lpc55 info, and read out memory
(with some restrictions).
lpc55 read-memory $((0x9DE00)) $((7*512)) -o output.bin
extracts the PFR (protected flash region) of an unlocked device.
The grand goal is to have an easily configurable
which allows creating and flashing SB2.1 (secure binary) files from
regular ELF files, signed via a PKCS#11 backend.
elftosb are semi-open source, officially
they are BSD-licensed, but code is only available behind a login screen.
pyMBoot is instructive but in Python (and a bit buggy in parts).
There is also the somehow underadvertised https://github.com/NXPmicro/spsdk.
