I have found that when sending config pdos to the drive it is successful in LinuxCNC but then lcec dies because it can't map some of the pdos that were just configured. If you do an "ethercat rescan" then the pdos are shown and LinuxCNC starts just fine. I'm not sure if this is an linuxcnc-ethercat or etherlab ethercat-master issue. This may still be some type of interaction with EoE but out of curiosity @endian could you please try seeing if that works for you as well vs disabling EoE?
LinuxCNC was not running during the following commands:

I do not know what exactly means lcec dies ... but commandshould restart your died ethercat service on your host PC...
I did that what I mention in the posts before... we are not in the situation that we are able to use FAoE, AoE or EoE .. but that time should come soon
My symphtons of not working ethercat service because of EoE on was that... sometimes communication between ethercat slave was turned on(less attemps) and comm was 0 (more attempts) .. but behavior was trully randomable... other slaves on bus was in opmode normally with EoE slave on the bus in same time ...

Hi Endian,
Sorry I wasn't clear...what I meant is the LinuxCNC dies because lcec errors out on not being able to map the PDO (for example 0x6060) even though it was configured with SDOs but for some reason not visible until doing the "ethercat rescan".
Perhaps these issues are not related but would be strange coincidence that EoE is involved in both. I'm not sure anyone is actually using it with LinuxCNC.

When I had such a problem like yours... I do not know but ... try check the active mapping with ... I think it is possible to run EoE but there are synchronization problem because it was not definated in the SDOs startup ... and it should does a mess
lets check what is exactly wrong with them withand after them should try and let us know
regards
ethercat pdos -vlets check what is exactly wrong with them with
ethercat debug 1sudo dmesgregards

I don't think EoE can work in LinuxCNC the way it is now unless possibly you are running linuxcnc-ethercat as a kernel module which I guess would require RTAI version. In the userspace version there is no call to ecrt_master_send_ext() which is required for EoE to work and it's only enabled if __KERNEL__ is defined. I opened a ticket on linuxcnc-ethercat so when Scott has a chance to look at it maybe there will be something.
