Hi,
We are using a Beckhoff CX2020 computer. We are running it as a non-gui controller with: Linux 2.6.32.11 RTAI 3.8.1 EtherLabs 1.5.2 The CX2020 has two e1000e NICs for the office network. The EtherCAT NIC is part of the CX2100-0004 power module but this is specialised hardware and we needed to write our own driver for it (submitted to the etherlab forum a while ago). We are building our Linux environment using Buildroot so that it is very small. Linux 2.6.32 does not support the graphics card for this PC but we are running it headless so not a problem for us. In the future we are intending to integrate our gui onto the same PC but we are waiting on RTAI and a few other things to come together first.

It seems to be hard ot find, maybe a dead end. We found working Xenomai using Ubuntu 12.04 with a patched 3.5 kernel, but it is not supported by Etherlab We do need a kernel with RT support but not necessarily Xenomai... You wrote that you were using Etherlab master via RTDM, but using RTAI. Can you share which releases / kernels that you are using?

In theory xenomai should be pretty similar. If you are using the latest 1.5.2 Etherlab master you won't need a patch. The patch was to give partial RTDM support before it was fully supported. To get RTDM working you will need to specify the correct flags when compiling the master: --with-xenomai-dir=<xenomai directory> --enable-rtdm All going well you should get a library: /usr/lib/libethercat_rtdm.so When compiling your application link to the library using: -lethercat_rtdm With RTAI you can check your application is using RTDM by calling 'cat /proc/rtai/scheduler'. The syscalls value should remain zero.

The plan is to have a user space rt-application calling the Igh master. Does it exist a procedure for how to get this working? I have tried to read through the mail archive and the examples, but have only found piecewise information. I have found mails mentioning patching of driver connecting Etherlab master to user space It seems to be special lib libetherkat_rtdm.so Hope someone can help :-) Best regards Steffen Dalgard SINTEF ICT Norway
