Hello,

Your cyclictest window shows that no High resolution timers,,,,,so you didn't need it ?

And also any good luck with the board is everything working good????
I am actually planning to put the RT patch in my Roboard-100 so your reply would be a great help.

Hi


So actually I switched to the xenomai framework with an adeos patch. I getted far more better results (latency between 20 and 50 us for interruption handling)

I only used the instruction from xenomai.

If you want I have some debian/ubuntu package I could share for the setup.

If you prefer to compile on your own the configuration, I give you here the config file I used from a vanilla linux-2.6.34.5 kernel with the latest xenomai patch, and just followed the xenomai instructions. This working fine for the RB 110 board. I don't know for other board.
