For a specific list of available boards, displays and input devices, contact QNX Software Systems info qnx. See the status page on the Qt Project wiki for details. If you build Qt from a released source code distribution archive, the configure tool ensures that the build will be made only for modules which are known to build for the target specified.

If you build Qt directly from the Git repository, you should initialize the repository only with modules which are supported or build and install modules separately.

This helps to prevent unexpected build problems. Building Qt 5 requires the following packages available from the QNX website registration required for access to downloads :.

The compiler and other parts of the tool chain are provided in the SDP packages. You do not need any additional installations on your host PC. However, it is advisable to ensure that you can build Qt for the desktop target on the host as well. See Building Qt Sources for more details.

The configure tool runs various tests to detect capabilities of the SDP and its add-ons. It sets related flags according the test results.

Check the configure summary on the console or in. This specifies the target folder where Qt will be installed and places all build artifacts outside of the source code tree. QNX Software Systems delivers software solutions for making embedded devices. Even though QNX provides several reference scripts for the OS image creation, sooner or later you will need to make changes or you might decide to create an OS image from scratch. Qt relies on the existence of several third-party components and selected OS services.

The sections below list the crucial parts for Qt.

The Screen consists not only of a driver, but also includes several utilities and other services which are used by Qt. This includes processing of mouse and keyboard events as well. You can ensure that the Screen is configured and running correctly by verifying that a graphics application, like gles2-gearscan be started and runs without problems. Most of the recent sample OS build scripts in the SDP include sections with all components and start commands for the Screen. Use them as a reference.

Qt's networking stack requires IPv6 support to be enabled, independent of whether the actual networking uses IPv4 or IPv6. That means, that io-pkt-v6-hc must be running, not io-pkt-v4. Start it before starting any Qt application or during the system startup:.Specifically, this chapter takes you through the tasks you must complete to boot a QNX Neutrino system on a target platform.

The information presented here is generic; that is, unless otherwise noted, the information is valid for all BSPs for the current QNX Neutrino RTOS release, but may lack some details required for specific boards.

The company was ultimately acquired by BlackBerry Limited in As a microkernel -based OS, QNX is based on the idea of running most of the operating system kernel in the form of a number of small tasks, named Resource Managers. This differs from the more traditional monolithic kernelin which the operating system kernel is one very large program composed of a huge number of parts, with special abilities.

In the case of QNX, the use of a microkernel allows users developers to turn off any functions they do not need without having to change the OS.

Instead, such services will simply not run. QNX Neutrino has been ported to a number of platforms and now runs on practically any modern central processing unit CPU family that is used in the embedded market.

QNX offers a license for noncommercial and academic users. QNX is also used in car infotainment systems with many major car makers offering variants that include an embedded QNX architecture. Gordon Bell and Dan Dodgeboth students at the University of Waterloo intook a course CS in real-time operating systems, in which the students constructed a basic real-time microkernel and user programs.

Both were convinced there was a commercial need for such a system, and moved to the high-tech planned community Kanata, Ontarioto start Quantum Software Systems that year.

Over the years QNX was used mostly for larger projects, as its 44k kernel was too large to fit inside the one-chip computers of the era. The system garnered a reputation for reliability [ citation needed ] and became used in running machinery in many industrial applications. In the lates, Quantum realized that the market was rapidly moving towards the Portable Operating System Interface POSIX model and decided to rewrite the kernel to be much more compatible at a low level.

The result was QNX 4. During this time Patrick Haydenwhile working as an intern, along with Robin Burgener a full-time employee at the timedeveloped a new windowing system. This resulted in QNX Neutrino, released in Inthe company announced it had been sold to Harman International Industries. Before this acquisition, QNX software was already widely used in the automotive industry for telematics systems. Since the purchase by Harman, QNX software has been designed into over different automobile makes and models, in telematics systems and in infotainment and navigation units.

Once configured by the automaker, QNX can be programmed to hand off its display and some functions to an Apple CarPlay device. The QNX kernel, procntocontains only CPU schedulinginterprocess communicationinterrupt redirection and timers.

Everything else runs as a user process, including a special process known as proc which performs process creation and memory management by operating in conjunction with the microkernel. This is made possible by two key mechanisms: subroutine-call type interprocess communication, and a boot loader which can load an image containing the kernel and any desired set of user programs and shared libraries. There are no device drivers in the kernel. The network stack is based on NetBSD code.

QNX interprocess communication consists of sending a message from one process to another and waiting for a reply. This is a single operation, called MsgSend. The message is copied, by the kernel, [ citation needed ] from the address space of the sending process to that of the receiving process. If the receiving process is waiting for the message, control of the CPU is transferred at the same time, without a pass through the CPU scheduler.

Thus, sending a message to another process and waiting for a reply does not result in "losing one's turn" for the CPU. This tight integration between message passing and CPU scheduling is one of the key mechanisms that makes QNX message passing broadly usable.

Most Unix and Linux interprocess communication mechanisms lack this tight integration, although a user space implementation of QNX-type messaging for Linux does exist. Mishandling of this subtle issue is a primary reason for the disappointing performance of some other microkernel systems such as early versions of Mach.QNX OS for Safety is a software solution that provides the reliable foundation necessary for building competitive automotive and mission-critical systems in a cost-effective and safe manner.

Building an automotive system compliant with ISO or an industrial automation or high-speed train control systems is complex and a significant undertaking. While functional safety requirements place emphasis on the system being deterministic and reliable, other competitive features demand the system to be more dynamic, connected and versatile.

QNX OS for Safety significantly eases the task of ensuring freedom from interference in systems with mixed criticality. Ultimately this translates into a lower certification effort. By taking on the qualification of these toolchains, BlackBerry QNX offloads this certification task from customers saving them valuable time and effort.

Developers already familiar with the standard RTOS require no ramp-up time when working with the safety-certified product and can use the same QNX Momentics tool suite. The API compatibility eases the learning curve for the development team, and leverage one common platform for safety-critical and non-safety-criticalapplications, thus maximizing code re-usage.
