Python script to calculate LPC firmware checksums

Python script to calculate LPC firmware checksums, based on the C version by Roel Verdult. It can be used as a standalone application, or as a Python module that integrates directly in a build environment (e.g. SCons). It does not need to be compiled.

Requirements

The only requirement is Python 2.7 or Python 3.5.

Installation

This module can be installed from Pypi via pip install lpc_checksum. Alternatively, you can install the latest version by cloning this repository and run python setup.py install.

Usage

There are two ways of using lpc_checksum.

Standalone

When installed via Pip or from source, the command lpc_checksum should be available on your PATH. By default, it assumes the input file is a binary file.

lpc_checksum <firmware.bin|hex> [--format=bin] [--readonly]

Program exits with a non-zero error code when it failed.

As a module

import lpc_checksum

checksum = lpc_checksum.checksum(input_file, [readonly=True])

On error, an exception will be raised.
