QNX Software Development Platform
QNX SDP is a cross-compiling and debugging environment, including an IDE and command-line tools, for building binary images and programs for target boards running the QNX OS 8.0.
- Quickstart Guide
- System Architecture
  The System Architecture guide accompanies the QNX OS and is intended for both application developers and end-users.
- OS Components & Operations
  - Boot Optimization Guide
    The Boot Optimization Guide describes techniques you can use to reduce the time from your board's initial power on until you have a fully functional QNX system running on the board.
  - Building Embedded Systems
    The Building Embedded Systems guide is intended for developers who are developing or building BSPs for QNX OS embedded systems.
  - Customizing a BSP
    While QNX provides Board Support Packages (BSPs) for many common platforms and their individual variants, in some cases, you need a BSP for a board that QNX does not provide. If this is the case, you can modify a QNX BSP or develop your own.
  - Device Publishers Developer's Guide
    - Device Publishers
      Device publishers are hardware-support components that publish information about attached devices. The QNX OS ships the usblauncher_otg publisher for USB-connected devices. This publisher sends information through its embedded resource manager publisher (RMPS) component. Applications use this information to access the content on devices, which allows them to display file information in browsers or to use multimedia services to read and play media files from those devices.
    - The USB Launcher Service
      The USB launcher service (usblauncher_otg) processes USB device attachments and detachments, launches drivers for communicating with devices, and publishes device information through RMPS. The service can also force a re-enumeration of a device, by resetting it or by requesting it to disconnect and change its personality.
