Hi,
I have a book on real time embedded systems but I would like to start getting my hands dirty on some RTOS. Which RTOS would be the easiest to learn from? Possibly free and that I can download from the internet.
thanks ivan

I suggest you to buy the following book: "MicroC/Os-II - The real time kernel" by J.Labrosse. The book is cheap, gives you an excellent background about RTOS in general, explain you how MicroC/Os-II works and contains a CD-ROM with the kernel source files which can be used not for commercial purposes, but help you to learn about RTOS.

It exists many good RTOS that you can have freely (moreover if you don't want to do a commercial purpose with it).
A good one (from my point of view), his eCOS under GPL licence and respect the posix specification. It comes (like most RTOS) with a PC simulation environment that can allow you to test your program easily without specific hardware. It is quite easy to install and configure if your are under linux otherwise it runs under cygwin but a minimum of unix skill is required.

I can recommend this and the documentation on the site explains how the RTOS works very well and very clearly.
Once you have your hands dirty, try RTEMS. Free, open source, and support and answers to questions available.

try FreeRTOS.
More accessible?? It's a free download. It's open source. Users are encouraged to contribute.
Better supported?? There is a mailing list at

which is monitored by OAR Corp. people. You can also get classes and support through OAR Corp (yes, you do have to pay for those).

eCos is on the more complex end of the spectrum, and might be a bit much for somebody with no RTOS background.
If you want to learn basic concepts and look at actual RTOS source code, Labrosse's book on uC/OS-II is very good (though uC/OS requires buying a license for commercial work). OSes like FreeRTOS or XMK are also pretty straight-forward.
In my experience it's a bit fragile under Cygwin, but with a bit of futzing you can get it to work.

Ivan,
MapuSoft offers products to move applicati> Hi,
Try QNX Neutrino RTOS vers. 6.3 (QNX6.3) ... a 30 days eval version is available. (

I'm sure the previous free version (QNX 6.2, free for non-commerc. use) is still available in the internet.
