[etherlab-users] Using Etherlab on a Xenomai system

[Dirk Castelijns]

Hi Andreas,

 

Thanks for the response.

 

We don’t really have a special need for a dual kernel system. It’s more like
a constraint. 

We are adding EtherCAT functionality to our customer’s system which is
Xenomai based.

 

I have read at different places that Xenomai supports an “RTAI skin”.
Shouldn’t this work with Etherlab?

 

Dirk

Hello

EtherLab <= 1.3 will not run under xenomai, because it is prepared for
kernel space usage. But Xenomai has no math libraries for kernel space. So
there is no chance.

Do you have a special need to use a dual kernel system.?

If not you can use the actual devel branch of etherlab >=2.0 which uses a
preempt-rt kernel.

Best regards

Andreas

Hi,

 

I’m a little bit confused about the RTAI / Xenomai compatibility of
Etherlab. Hopefully someone

can help me with this.

 

We have a Xenomai system where we want to add EtherCAT functionality. For
this I want to 

use the EtherCAT Master software and the Etherlab software together with
Simulink RTW/Coder.

Installing the EtherCAT Master software was no problem. Etherlab requires
RTAI sources and

a kernel patched for RTAI but our kernel is already patched for Xenomai, so
is this going to work?

 

Thanks.
