Hello,

I am using the latest SOEM component from git. I have: - Ubuntu 12.04.2 - Xenomai 2.6.2 - RTNet 0.9.13 - ROS Fuerte - Orocos 2.6.0

I am having a "CPU time limit exceeded (core dumped)" error when I run Master.configure using the soem_master/test.ops script and deployer-xenomai. I didn't forget to set up ifname="rteth0".

My Ethernet controller is: Intel Corporation 82566DM-2 Gigabit Network Connection.

I did not forget to set up -DENABLE_RTNET=ON in soem_core/Makefile.

The trace from the core dump is the following:

1. 0 0xb77b8424 in __kernel_vsyscall ()

Peter already answered the same kind of question once: <http://lists.mech.kuleuven.be/pipermail/orocos-users/2012-August/005796.html> but I was not able to find any evidence of T_WARN_SW being turned on (and T_WARN_SW yields only 3 results on Google, that didn't make it any easier).

I succeeded to run soem_core/bin/slaveinfo, it found my EtherCAT slaves and configured them. Thus I am not sure the problem comes from the ethernet controller (_although_ it is not offically listed in RTNet documentation <http://www.rtnet.org/doc.html>).

Do you have any idea?

Many thanks in advance, I spent hours trying to figure out this problem.
