RTOS licensing varies widely - there are several common models and none 
that are followed by "most commercial RTOSs".  The four most common 
models are royalties on shipped products, licenses per developer (or 
site), licences per projects, and various open source licenses.  Some of 
these open source licenses (such as pure GPL) are very restrictive in 
practice, others are much more friendly (such as FreeRTOS's GPL + 
exception).

With GNU tools, you are on your own - if you want to be on your own.  If 
you want help, there are plenty of free sources.  If you want 
commercial-level support, there are plenty of companies offering such 
support (at an appropriate price, of course).  Support options for GNU 
tools are not really that much different from support options for 
commercial tools - there is a variety available, at varying prices, and 
varying quality.  One plus side is that for popular tools there are 
often several support suppliers - a down side is that it is not always 
as easy to find them as for commercial tools.

So is SCIOPTA, but different architecture (Direct Message Passing).

(Disclaimer: I work for SCIOPTA, and yes I want to sell it :-) though
I am one of their code-slaves)

A short answer. I have used embOS in the past and it is a fine RTOS. I
also dare to disagree with Scott about uCOS-II being better, have
looked into both and embOS appeared to be more feature rich.
Ecosystem: it is definitely true that uCOS has a good market
acceptance in the US, embOS "home market" is Europe and it is used by
many major companies. There are all kind of drivers for uCOS, such as
Ethernet - TCP/IP, USB-HS, CAN, File System, USB-Host, USB-device, LCD
some are developed by Micrium, others are 3rd party implementations
(e.g. uC/GUI and emWin seem extremely similar).

As for embOS, TCP/IP, FS, LCD, USB-device are all developed by Segger,
so the know how is inhouse.

Going with embOS would also give you a very good support person
located in MA assuming you are actually in the US yourself.

Hope this helps,  an Schwob

It is very widely used in Europe.

Better in what way?   Swings and roundabouts. It depends what you are 
doing

>very difficult to find any good reviews of embOS.

There is no mystery here....

I have lots of people using it.  All very happy with it. The trouble is 
they are all working on projects in companies they are not likely to 
talk about.

Being free FreeRTOS has a community of students and hobby people who do 
talk about it.

That is why you see more chatter about freeRTOS.

That is a set of questions from a company selling RTOS so it will be 
biased to their own RTOS

I have had no complaints from my users and they often use embOS on new 
targets once they have tried it on one.

This is true. embOS is German in origin so it started in Europe. It is 
very well engineered and reliable. Just as you would expect from German 
Engineering. It has been used in all sorts of things from Aircraft and 
medical to cars and washing machines...

>As for embOS, TCP/IP, FS, LCD, USB-device are all developed by Segger,

Also a very good Graphics system and they are expanding their range of 
modules for the RTOS

It does everything including making the coffee... there is a high end 
coffee maker that uses Segger SW.

That would be Shane. He is good.

So don't let the lack of chatter about embOS put you off. The engineers 
using it tend not to chatter in Usenet.  Try the demo version,.

That's new to me. AFAIK emBos has no own TCP/IP. They _had_ a third
party stack.
