  VxWorks at Arcom: PXA255 XScale Development Kit for Wind River VxWorks 5.5
Wind River's VxWorks real-time operating system has a strong reputation for high reliability and consistent, low interrupt latency.
All support issues relating to the VIPER single board computer and the standard VxWorks image should be directed to Arcom Technical Support.
Long term support for VxWorks is available through the standard Wind River support contract.

  IOTA - How to write software for VxWorks   (Site not responding. Last check: 2007-11-04)
VxWorks is a "preemptive" multi-task OS: each task has a priority level ranging from 0 (for the highest priority) to 255 (for the lowest priority).
A VxWorks software consists therefore of one or several tasks that must be developed on a dedicated computer (a Sun workstation for the IOTA environment) using preferably a development environment called "Tornado" (the version we describe here is Tornado 2.0 for Solaris).
Displays tasks currently managed by the VxWorks system.Among the displayed parameters are the name, the priority level (0 for the highest priority, 255 for the lowest), the task ID (in hexadecimal), and the status of the task (pending, ready (=running), suspended).

 VxWorks - Wikipedia, the free encyclopedia
VxWorks is a Unix-like real-time operating system made and sold by Wind River Systems of Alameda, California, USA.
Unlike "native" systems such as UNIX and Forth, VxWorks development is done on a "host" machine running UNIX or Windows, cross-compiling target software to run on various "target" CPU architectures as well as on the "host" by means of VxSim.
VxWorks is in use in several other spacecraft as well, for example, the Deep Impact mission.

 Comments on VxWorks
VxWorks is designed for scalability, enabling developers to allocate scarce memory resources to their application, rather than to the operating system.
VxWorks was the first real-time operating system to integrate industry-standard TCP/IP networking facilities optimized for real-time applications, and continues this tradition of innovation.
VxWorks 5.2 is the most consistently supported real-time operating system and development environment available today across the broadest range of target processors.

 Bootable ROM-Based VxWorks Image
A VxWorks image is the actual VxWorks Operating System program in non-relocatable object format that is loaded in and runs on the target processor (the VME board).
VxWorks provides many optional features that can be included or removed from a build; examples of these features are C++ support, networking support, debug facilities and etc..
The boot program that is normally used to load the VxWorks image from over the network or disk device provides the operator the ability to modify parameters pertaining to the network such as the host and target names and IP addresses.

 How to port Python to VxWorks   (Site not responding. Last check: 2007-11-04)
Background: VxWorks is a Real Time Operating System (RTOS), meaning that you can in theory make "real time" applications on it that respond to time critical events in a (guaranteed) timely fashion.
VxWorks development is often done using a cross compiler, typically using a product from WindRiver Systems called Tornado, which is a development shell around the GNU tool suite (GCC, GDB).
Since VxWorks is typically hosted on a machine other than the target board, this approach won't work, since at best you'd get settings for the host, not the target.

 comp.os.vxworks Frequently Asked Questions (FAQ) [LONG]
Given that VxWorks is a real time embedded OS, I, for one, don't care if WRS uses the current implementation even though it isn't "pure" because the result is a more reliable implementation that runs more deterministically.
Free lex and yacc for use with VxWorks John Winas (winas@phebos.aps.anl.gov) writes, I just (moments ago) uploaded the two packages to thor.ncar.ucar.edu where the vxWorks archive is. When ever the maintainer moves it into the release area they will be available to everyone.
The VxWorks exploder FAQ now includes a proposed replacement routine for 68040 systems, however, I have examined this routine and found it to be grossly in error in cases where the divisor is less than 1.0.

All VxWorks makefiles pass along the definition of this variable to the compiler.
One outcome of the necessity that the virtual and real addresses must be equivalent, is that two copies of the VxWorks run-time (for example, on two processors running their own copies of the VxWorks image) cannot share the same physical address space for running VxWorks.
Typically, in VxWorks, the BATs are only used to map large external regions, or PROM/Flash, where fine grain control is unnecessary; this has the advantage of reducing the size of the PTE table used by the segment model.

 Dr. Dobb's | Examining the VxWorks AE 1.1 RTOS | October 1, 2002
VxWorks AE is a real-time operating system (RTOS) from Wind River Systems (http://www.windriver.com/) designed for embedded applications with demanding requirements currently on the Intel, PowerPC, ARM, and MIPS processor families.
VxWorks AE extends the single, flat physical address space of the VxWorks environment to multiple, virtual address partitions in which applications can run.
VxWorks AE's protection domains are an alternative to the traditional process model (Wind River refers to this as the "legacy protection model") used in most other operating systems.
