Patch A for QNX RtP 6.2.0 Released

From QNXZone: QNX Software Systems has released the Patch A for all versions of QNX Momentics. There is no readme or changelog available, so the only information available on what is included in the patch is from the short summary on QDN that reads as follows: "It provides enhancements and addresses some of the general issues pertaining to Voyager, Phplay, and Photon microGUI".

QNX Momentics 6.2 Non-Commercial Edition Released

After many months of waiting, QNX RtP (now called QNX Momentics) 6.2 is released. The new version has many fixes, new features and more device driver support. It requires a PIII-650 or better (however, I have successfully ran its beta on a 233 Mhz PC with 64 MB RAM a few months ago), 128MB RAM and 1 GB disk space. QNX Momentics' primary target are embedded developers instead of end users. Please note that QNX 6.2 does not support anymore the FAT32-installed QNX boot image, but instead, it requires its own partition. The ISO available for download is 195 MB. You can read our world exclusive preview of QNX 6.2 we published last January, here.

QNX Previews New IDE for Embedded Development at ESC

Embedded developers who choose the QNX RTOS for its unmatched reliability will soon have another reason to use QNX technology: significantly faster development cycles. This is all thanks to the new QNX integrated development environment (IDE), to be showcased next week at the Embedded Systems Conference (ESC) in San Francisco. Show attendees can have a sneak peek at this QNX offering in booth #818.

QNX RtP 6.2 — World Preview

QNX is an operating system that all of us have used, but few of us realize it when we do. The OS was created in the early 1980's by QNX Software Systems, a Canadian company, but the version we are previewing today (unreleased yet, version 6.2), based on the Neutrino kernel, was pretty much (re)written from scratch some years ago. QNX is used everywhere, from VCRs, to DVDs, to medical machinery and even satellites and space shuttles. Many of you maybe even have tried the old demodisk, a demo of the QNX4 RTOS, plus the previous version of the Photon GUI, fitting in a single 1.44 floppy. The desktop-enhanced version of QNX RtP (free for non-commercial use) runs on almost all modern x86 CPUs, and if we judge from the following screenshots, it looks pretty good for an embedded system OS.

Longtime (old) QNX User Stories

"Since qnxZone was launched, I have been thinking that the stories of some of the long time QNX users may be of interest to the community. As one of the longer time (older) users, I figured I would start it off. Now this story starts in 1986, but in order for it to make more sense, you have to go back to the late '70s when I was in high school. I went to high school with Dan Hildebrand, who went on to become a significant player in the QNX community. We went to school in Winnipeg, but after high school I joined the Canadian Military and took off for other parts of the country. I lost touch with Dan other than the occasional contact when I was back in Winnipeg visiting family and such. By 1986 I was stationed in Victoria, BC, going to university under a program in the military." Read the rest of the story at QNXZone.

QNX Real-Time Performance & Robustness Evaluation Report

"This report is a real-time performance and robustness evaluation of the QNX v6.1 RTOS from QNX Software Systems Ltd. Aside from the standard performance tests, the test suite has now been expanded with several stress tests. The evaluation report covers the following topics: Theoretical study of the architecture, API, tools, development method, Interrupt Handling, Thread Handling (thread creation, thread switch latency, Synchronization mechanisms (semaphores, mutexes, priority inversion), File system performance, Network stack performance, Advanced Interrupt Handling (two simultaneous interrupts, nested interrupts, maximum sustainable interrupt frequency, ...), Memory leak detection, Real-time performance monitoring with varying system loads."
