We are kind of a spin-off. But only the basic idea (direct message
passing) is the same which is _not_ an ENEA brand BTW.
More on Sciopta's history ?

Sciopta's functionality is comparable OSE Delta with the size of 2
times OSE Epsilon :-)
On ARM: 2K (minimal set of functions needed for an application) to 
18K (all functions) ROM footprint.

I add one more: Worse if you have no source at all.

Only thing our customers struggle a bit: Our kernel is written in
assembler. It is sometimes the first time they need to see assembler
sources :-)

hi,
this is really cool RTOS, because it's based on HW.
However, is there any customer adopting it? and is it cheap?

But my experiences spans 2 decades and seven or more RTOS vendors
.. of which only two vendors have given what I consider to be
*acceptable* support!!

Generally I have not been the one making the
original decision... just dealing with the consequences! :-(

It should be remembered once you pick an RTOS for a product,
you are pretty much locked in for the life of the product.

There is nothing worse than working on a RTOS, where
you don't have source, where the vendor decides to
stop supporting a particular processor!

Since moving to rtems, on the rare occasions where I have
had a problem I have ALWAYS been pleasantly surprised by
the level of support the developer community provides!

Generally I would say whatever you do, commercial or open source
make sure you get an RTOS with source code,
that way you ALWAYS have the option of fixing problems yourself.

Regards

Paul

Hey, that's cool: An RTOS in hardware.

You bought from the wrong company :-)

Tip for evaluation an RTOS: Send a stupid support question and check
how long it takes that you get an answer.
If support is bad during evaluation it won't be better when you've
bought.

Did you go to my employers web-site : www.sciopta.com ?

Check out the PDFs found there and if it is not enough info drop me an
email bastian.schick@<company>.com

But be aware: It is direct-message-passing, no global variables and
_no_ semaphores :-) but with 6 system-calls you can build 80% of your
application !

With commercial support if you require!

The free community support is better than anything I have ever got as a
result of paying for it!
