Hello, I'll try to explain better what my colleague was trying to say in his last email:
1.- Is there any special option to configure/compile the EtherLab Master code in order to be suitable to work under RTAI real time kernel? 2.- After compiling with option "--with-rtai-dir=/usr/realtime", when we run the rtai examples and/or our own software we get a huge amount of syscalls in the rtai hard realtime task (cat /proc/rtai/scheduler), what means that something is calling linux system and so leaving the hard real time context. Are these syscalls the "normal" behaviour of the EtherLab Master, or we must be doing wrong something else? 3.- Although we still don't know exactly if these syscalls are the cause of our problem, sometimes we get very big overruns of our real time task, which is using the EtherLab Master to communicate to some Beckhoff modules. Does anybody have these big overruns using EtherLab Master? Thanks in advance. On Wed, 4 Apr 2012 14:25:49 +0200, Richard Hacker <[email protected]> wrote: > Hello, > > have you tried the examples.
