# spsdk — Open Source Secure Provisioning SDK for NXP MCU/MPU

License: permissive · Maintenance: active · Downloads: 545.9K/mo

## What it is and what it does

SPSDK is NXP's official open-source toolkit for secure provisioning and programming of their microcontroller and microprocessor devices. It provides both a Python library API and command-line applications, enabling developers to automate device configuration, firmware flashing, and security provisioning workflows. The package wraps low-level device communication protocols and bootloader interfaces, abstracting away the complexity of direct hardware interaction.

The library depends on 33 runtime packages covering cryptography (cryptography, pyasn1, oscrypto), binary manipulation (bincopy, bitstring, hexdump), serial communication (pyserial), USB access (libusbsio, libuuu), and configuration parsing (ruamel.yaml, fastjsonschema). It is actively maintained, supports modern Python versions (3.10–3.13), and runs on Windows, Linux, and macOS. The permissive BSD-3-Clause license permits commercial use.

Use it for:

- Automate batch provisioning of NXP MCUs in manufacturing workflows using the Python API
- Program and configure NXP devices from CI/CD pipelines for embedded product testing
- Develop custom provisioning tools that wrap SPSDK for device-specific workflows
- Secure-boot configuration and key provisioning on NXP microprocessors
- Firmware update and recovery operations on deployed NXP devices via serial or USB

## Worth the install?

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

SPSDK is a Python library and CLI toolkit for connecting to and securely provisioning NXP microcontroller and microprocessor devices, handling firmware programming and device configuration.

Yes, if you develop with NXP microcontrollers or microprocessors. SPSDK is the official, actively maintained provisioning toolkit from NXP with no known vulnerabilities, low install friction, and permissive licensing. Install it when you need to automate device programming, secure provisioning, or bootloader interaction; skip it if you target non-NXP hardware.

## Install

pip install spsdk
uv add spsdk
poetry add spsdk

## Installing spsdk

Before you install: Low install friction; pure Python wheel with no compiled dependencies. Actively maintained with a recent release (56 days ago) and ongoing repository activity. Supports Python 3.10 through 3.13.

License in practice: BSD-3-Clause permissive license allows commercial and private use with minimal restrictions; you may use, modify, and distribute the package provided you include the license notice.

Quickstart:

pip install spsdk

from spsdk import apps
from spsdk.mcu import get_mcu

# Connect to and communicate with an NXP device
mcu = get_mcu('device_name')

Requires Python 3.10 or later. Target device must be physically connected and accessible via USB or serial interface.

Verify before relying:

- Specific NXP device models and bootloader versions supported by this release
- Whether libusbsio and libuuu (native USB/UUU protocol libraries) are bundled or require separate system installation
- Real-world provisioning workflow examples beyond the GitHub examples directory
