[etherlab-users] ethercat + xenomai on arm926 cpu system

[paluan.luca at tiscali.it]

Hello everyone,
I'm trying to develop a real time server on the arm 
(arm926) cpu and on a real time linux with xenomai.
Unfortunatly even 
the basic examples seem not to work on such a system: the real time 
task is set to work with a 2ms period like the 2 servos connected to 
the ethercat net (even though 1ms would definetly be the best).
With a 
bare example I immediatly receive warning from ethercat master of 
skipped frames and if the real task has to do something more the server 
crashes...
I tried various compile time optimizations and  I tried to 
give up with real time task using hrtimer without results.
My system is 
using the generic ethernet driver too, but could anyone give me some 
advice about whether the cpu power is enough to manage the ethercat 
driver in a real time environment?
Thanks in advance, Best Regards Luca
