About This Document

Updated: May 06, 2022

The Building Embedded Systems guide is intended for developers who are developing or building BSPs for QNX Neutrino RTOS embedded systems.

About this guide

This guide provides information about how to build and customize:
  • QNX Board Support Packages (BSPs)
  • QNX Neutrino RTOS embedded systems
  • the startup of QNX Neutrino embedded systems

It is organized thematically rather than sequentially; that is, you should refer to the chapters relevant to the task you are doing, rather than work through the book from start to finish. For instance, if you need to learn how to customize the QNX Initial Program Loader (IPL), you should first read the Overview chapter, then the Initial Program Loaders (IPLs) chapter.

Because you will likely be working with a QNX BSP, the BSP chapters are near the front of the guide, right after the Overview chapter. You should also refer to the BSP User's Guide for your target platform. This guide is available from the QNX SDP Board Support Documentation page.

Note: We assume that you've already installed QNX Neutrino and that you're familiar with its architecture. For an overview, see the QNX Neutrino System Architecture guide.
