hello, folks
have anybody ideas about what should be wrong with this configuration? It started right after fresh lcnc start, but when you want to restart it for first time, it do not go to OP and no datas are provided... Sometimes it going to OP with stable data trasfer but it is very very rare.
I can read actual configuration from slave via
ethercat-conf.xml file looks like
dmesg from ethercat shows
have anybody experiences with similar behavior please? I looks like rabbit hole right now...
thanks, Regards

So this is a Nidec/Control Techniques Digitax HD M753 servo drive?
I suspect your problem is that you're trying to set PDOs using 'sdoConfig' and that's eventually making things unhappy. Setting SDOs incorrectly in the XML *probably* won't result in an immediate error, which makes debugging annoying. Try `ethercat download` on the command line and see if that works without an error?
ethercat download -p 0 0x60c2 0x01 --type uint8 01
ethercat download -p 0 0x60c2 0x02 --type uint8 0xfd

I just checked in a tiny fix that should get better error messages when setting SDOs from XML; it should end up being linuxcnc-ethercat v1.13.1. It'll probably be available as a .deb in ~5 minutes.
A bit of overly technical background: there are a few ways to set SDOs in code using the Ethercat library that we're using. The main one is ecrt_slave_config_sdo(), which is what we mostly use when setting SDOs from XML. Unfortunately, it's actually an asynchronous call. It mostly only returns errors if there is a memory allocation problem. If the device is unhappy with the SDO, then we won't know until later. To get responses immediately, we want to use ecrt_master_sdo_download(), but it has *other* problems; anything that it sets will be lost if the slave is rebooted, while ecrt_slave_config_sdo() remembers its settings and re-downloads them if the slave restarts.
So, the fix is to use both every time we set a SDO. I'd fixed most of the settings earlier in the week, but the XML case wasn't handled right yet.

it is look like there was other problem... driver has EoE from default and it is linked to same hardware adapter with two different network adapters names... I found that name with
and there was someting like
then take that name and edit the network interfaces with
and add to last empty row this stuff
then I restart the netwoprk manager or restart the PC ...
Everything started to work without problem...
but when I create shell file like this
I can put it just before lcnc startup, no errors should happend I think
