I've been reading about FreeRTOS and seems like its widely used on microcontrollers and microprocessors like RasPi/BBB etc. I also read that it can be run on x86 platform and I want to test it.
Can I run FreeRTOS as a VM on virtual box or VMware?
Whats the best way to use FreeRTOS on x86 platform?
Thanks in advance.
One solution to use FreeRTOS on x86 is to run an available FreeRTOS simulator.
e.g. FreeRTOS Windows port:
This allows FreeRTOS to be run in a Windows environment - although
true real time behaviour cannot be achieved. Demo projects are
provided for both Eclipse with MingW (GCC) and Visual Studio 2010
Express Edition.
See the Richard's answer on this topic:
Building FreeRTOS for x86
but [...] the timing is all over the place and simulated time is much lower than
real time (because the timing resolution and accuracy in Windows is so
low compared to a real time system).

I wonder by any chance is there a way to install vxworks on vdx86d(vdx6354)? I searched a lot on the net and did not find NO to this question, but no manual or help could be find by me. anybody did this before and know how to do it?
VxWorks certainly runs on PC architecture x86 targets; there is probably already a suitable 80486 BSP that will suit this board. You can search for a suitable BSP here. There is only one BSP explicitly listed for 486 targetted at VxWorks 5.4/Tornado 2.0 - so it is as antique as 486 architecture itself. VxWorks 6.9 however has a single unified BSP for x86 which will no doubt work with your board.
VxWorks is not "installed" as such in the same way as a GPOS such as Linux or Windows; rather you link your application with the VxWorks libraries to create an application image that runs directly on boot. How the bootstrap process works varies between architectures and hardware implementation, but as a generic PC architecture board, booting a VxWorks application on your board will be the same as any other PC target. As such what you need to look for are directions on booting VxWorks on PC architecture rather then being specific about your actual board.
On PC architecture you can boot from mass-storage, or from a network server. Booting via a network connection is the normal method during debug/development. A great deal of the information available is for older versions of VxWorks. However it seems that it is possible to boot VxWorks via a VxWorks specific bootstrap, or from a generic PC bootloader such a s U-Boot.
Ultimately Wind River Support is probably a good starting point.
Is installing MONO on an IBM RISC running AIX possible and or practical?
And if so where do I start?
AIX is not one of Mono's supported platforms.
From the FAQ:
Mono currently runs on Linux, Windows, Solaris, FreeBSD and MacOS X. The Just-In-Time engine (JIT) is available on x86 and PowerPC, Sparc and S390 processors and can generate code and optimizations tailored for a particular CPU. Interpreters exist for the Itanium, HP-PA, StrongARM CPUs.
You could always download the source, and compile it yourself, after working out the platform specifics. Namely, the JITter would need to be ported to handle the processor.
I think this is a common problem for all developers using Windows CE 6.0 operating systems on specific hardware. I have a client that needs a custom operating system for its ICOP PDX-089T PC with Touch panel, that is based on DM&P SoC CPU Vortex86DX-1GHz.
I do not have the hardware with me, so every time I make a change I have to send at least the NK.bin file, or the whole ghost image to the client to make the tests for.
Is there any way to build a custom Windows CE emulator to add it to Visual Studio 2005 for testing or may be a custom virtual machine to launch it through VMWare or Virtual PC?
I tried some guidelines from the internet to build one, but every effort in making one resulted in hanging up my PC.
Does anybody have similar needs and some solution?
Note: The emulator I need is for Vortex86DX processor and ICOP board.
Microsoft abandoned the x86 Emulator some time ago, choosing to support only an ARM emulator (the BSP ships in the box with Platform Builder 6.0). This means that you can't create an emulator for the x86 processor, though I'm hard-pressed to think of a scenario where you'd really need to and where just getting hardware isn't a better solution for anyway.
There is a BSP for doing Virtual PC OS builds that would run on x86. It's not had much activity in some time, and I've never tried it, so YMMV.
Short of buying a SPARC processor, what emulators are there? Thanks.
Pickup a second hand Power Mac G5 and you can run a fairly recent version of a mainstream OS (ie. OS X 10.5.8) and a modern development environment (Xcode 3.1.4).
You get a pretty fast, modern RISC machine running an OS that is still highly used (for the time being, I admit.)
You could also install Linux onto it if that would be better for your needs.
Probably a lot easier to find and cheaper than a SPARC machine.
You could also install the SPIM emulator for MIPS
On revisiting this, it's worth noting that nearly all modern smartphones run on ARM processors, which is short for 'Acorn RISC Machine'. So, an easy answer is 'Android Studio' or anything else targeting phone applications.
Similarly, there's a plethora of simple development boards available inexpensively, such as the BeagleBone Black and the Raspberry Pi, that also carry ARM processors.
As i know java programs are able to run on any Operating System.
and there are JVM's for any kind of machines.
I need a JVM that runs on my PC stand alone, and not on my OS (windows or any thing else).
I mean a JVM that acts like a boot, instead of the OS boot
i searched for all versions of JVM on "www.java.com/en/download/manual.jsp", but i did not get the suitable JVM.
the following link helped me a little but that was not enough
http://java-virtual-machine.net/other.html#jvm
my PC CPU is AMD Athlon(tm) 64X2 Dual Core Processor 5200 + 2.69 GHz
any body can help me to find the suitable jvm version ?!
Sure, have a look at JRockit Virtual Edition. As I understand it it's basically a micro kernel especially tailored for the JRockit VM.
From this page:
Java without the OS: JRockit Virtual Edition (VE)
Am I the only one that's never heard of this before? The Oracle JRockit team is looking at eliminating the OS from the stack required to run Java. This product will be called JRockit VE (not out yet)
JavaOS
Good lucking getting hold of it, though, it's nothing more than a historical curiosity.
There are two JVMs that I am aware of, which have this property:
The Fiji WM: http://www.fiji-systems.com/index.html
According to http://rtjava.blogspot.com/2009/11/new-real-time-vm-was-born-fiji-vm.html it also runs on bare metal.
The next possibility is JNode: an open source operating system where most parts are written in Java (the rest in assembly): http://www.jnode.org/
JNode is still beta, though.
No.
There was an idea of making a machine that could run a JVM as an actual machine (non virtualized), similiar to LISP machines, but that idea never took off...
You need a host OS to run a JVM.
Googling "java real machine" might give you some interesting articles.
I've found two: one from 2004, talking about how such a machine could be built and another one, talking about how JVM runs as a real machine on hardware such as mobile devices.
Still, no dice with a plain PC.
