# libuuu — A python wraper for libuuu.

License: permissive · Maintenance: active · Downloads: 405.5K/mo

## What it is and what it does

libuuu is a Python wrapper around NXP's libuuu C++ library, which provides low-level access to NXP microcontroller bootloaders and device programming interfaces. It enables developers to programmatically flash firmware, access device bootloaders, and communicate with NXP embedded systems over USB. The package ships with pre-built binaries for common platforms (macOS, Linux, Windows on both x86 and ARM architectures), though it requires Python 3.9 or newer.

The wrapper is part of NXP's mfgtools ecosystem and is actively maintained. It carries a Pre-Alpha development status, indicating the API may still evolve. No runtime dependencies beyond the compiled libuuu library itself are required, though building from source demands C++ toolchain setup with vcpkg, CMake, and platform-specific build tools.

Use it for:

- Flash firmware to NXP i.MX microcontrollers during manufacturing or development workflows
- Automate bootloader access and device recovery procedures in production environments
- Integrate NXP device programming into custom Python-based build or deployment pipelines
- Access low-level device communication for embedded system diagnostics and testing

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Python wrapper for libuuu, a library for NXP microcontroller device programming and firmware flashing.

Yes, if you need to program NXP microcontrollers from Python. The package is actively maintained, has no known vulnerabilities, and offers pre-built wheels for common platforms. Pre-Alpha status means the API may change, so pin the version in production. Install friction is moderate but manageable via pre-built binaries on standard platforms.

## Install

pip install libuuu
uv add libuuu
poetry add libuuu

## Installing libuuu

Before you install: Medium install friction due to compiled binary dependencies across multiple platforms (Windows, macOS, Linux). Package is actively maintained with recent commits and no known vulnerabilities. Pre-built wheels available for common architectures reduce setup burden for standard platforms.

License in practice: BSD-3-Clause permissive license allows commercial and private use with minimal restrictions; attribution required.

Quickstart:

pip install libuuu
import libuuu
# Use libuuu functions for device communication

Requires Python 3.9 or newer. Pre-built wheels available for macOS (arm64, x86_64), Linux (aarch64, x86_64), and Windows (32-bit, 64-bit); manual build of underlying C++ libuuu library required on unsupported platforms.

Verify before relying:

- What specific NXP devices and bootloader protocols are supported by this wrapper version
- Whether the package works with all NXP i.MX processor families or a subset
- API stability guarantees given Pre-Alpha development status
