[Etherlab-users] Master EoE Support

[Kevin Wormington]

Hi,

I'm using the RT_PREEMPT kernel with LinuxCNC 2.9.3 and
ethercat-master_1.6.1.g419f621 from the opensuse repository that the
LinuxCNC iso instll sets up.

I'm having an issue trying to get EoE to work...the devices are created and
can assign an IP but the link will only come up if LinuxCNC is running (ie
linuxcnc-ethercat is loaded).  Even with the link up I'm not able to ping
or have communication.   There is also an issue of config SDOs being loaded
to slaves and then when linuxcnc-ethercat tries to map them it errors out
with undefined PDOs.  This can be fixed by an 'ethercat rescan'.  If EoE is
disabled in the etherlab master this issue does not occur so I think they
may be somehow related.  I've posted on the LinuxCNC forum and no one seems
to be using EoE.  I would like to try and diagnose this further as I'm not
sure if it's a problem with etherlab master, linuxcnc-ethercat, or both.

This issue (
https://lists.etherlab.org/pipermail/etherlab-users/2024-April/019374.html)
seems to be similar to the undefined PDOs occurring here with a solution of
disabling EoE.

Should EoE communication work with just the etherlab master running?

Any ideas on how to try and narrow this down?

Thanks,

Kevin
