Finally a new RTOS. Great, we all have been waiting for a free RTOS
for soooooo long.

Did you bother to look at the site, or is this just a knee-jerk 
reaction?  Yes, Nutxx is another free RTOS - but there is space for a 
selection of RTOS's in this world, both free and non-free.  There are a 
great many people using free OS's of various sorts and various sizes. 
This one seems to be "bigger" than FreeRTOS, but "smaller" than ecos - 
I'm sure there are people here who will look at it with interest.

In a way, yes :-)

I've seen, it is actually quiet "old" (already version 5).

Sure. But I just wonder why again and again new RTOS's appear, and all
repeat the same philosophy (shared memory, semaphores).

Despite many others that now and then appear NuttX seems pretty
complete in what it offers.

You've got further than me - I only got as far as reading some of the 
website.  But I have made a note of it for the future - maybe it will be 
useful to me.

Most RTOS's (free or otherwise) have reasonably similar designs, as far 
as I  have seen.  However, I could well imagine applications where some 
of the features of Nutxx, such as its shell and its file system support, 
would make it a very strong contender.  To my mind, that makes it 
another /interesting/ free RTOS.
