[En-Nut-Discussion] NutOS Unix emulation status?

[Matthias Ringwald]

Hi there

sometimes, I'll browse through this mailing list and get caught by the  
subject. :)

The Unix Emulation works at least partially. I've added it long time  
ago to help with the debugging of our Bluetooth stack. Yet, the timers  
implementation could need some re-work, to make use of the simplified  
timers in nut/os introduced some years ago - but hey, it's working. If  
I remember correctly, it only supports the emulations of the UARTS,  
but these can be mapped to stdout, a real serial port or even to a tcp/ 
ip socket.

I don't know if this is in the Nut/OS docs or only in ours.
http://www.btnode.ethz.ch/static_docs/doxygen/btnut/group__btn__unix__emulation.html

To get started, I can recommend to grab the latest version of nut/os  
and btnut from their respective repositories.
Then in btnut/Makedefs enable the this line:
PLATFORMS     += unix

run make and have a look at the examples in the app folder. e.g. the  
app/threads example works right out of the box.

I can only say that a) it builds fine with the BTnut build system,  
which essentially is a tweaked version of the nut/os one, and b) there  
is no further development from our side. But I hope the current  
version is at least a good start to, as you've asked for, add e.g.  
networking stuff.

Cheers
  Matthias Ringwald

p.s. btnut is available at http://www.btnode.ethz.ch/
