Ethercat installation from repositories - how to step by step

Category: EtherCAT

Is it safe to say the Linux Raspberrypi 6.12.11 #1 SMP PREEMPT_RT doesn't work with Etherlab Ethercat Master version 1.6.2. Trying to setup EtherCat on Pi5 with Debian.

I have issues starting the ethercat service.
sudo systemctl enable ethercat

Job for ethercat.service failed because the control process exited with error code.
See "systemctl status ethercat.service" and "journalctl -xeu ethercat.service" for details.

Here's what shows in the journal
Feb 05 12:13:12 raspberrypi ethercatctl[53739]: ERROR: No network cards for EtherCAT specified.
Feb 05 12:13:12 raspberrypi ethercatctl[53739]: Please edit /etc/ethercat.conf with root permissions and set MASTER0_DEVICE variable to either a network interface name (like eth0) or to a MAC addre>
Feb 05 12:13:12 raspberrypi systemd[1]: ethercat.service: Main process exited, code=exited, status=1/FAILURE

Looks like some files are missing or can't be found when trying to install the modules?
sudo make modules_install

returns

cnc@raspberrypi:~/ethercat$ sudo make modules_install make -C "/usr/src/linux-headers-6.12.11" M="/home/cnc/ethercat" INSTALL_MOD_DIR="ethercat" modules_install make[1]: Entering directory '/usr/src/linux-headers-6.12.11'   INSTALL /lib/modules/6.12.11/ethercat/examples/mini/ec_mini.ko   SIGN    /lib/modules/6.12.11/ethercat/examples/mini/ec_mini.ko At main.c:171: - SSL error:FFFFFFFF80000002:system library::No such file or directory: ../crypto/bio/bss_file.c:67 - SSL error:10000080:BIO routines::no such file: ../crypto/bio/bss_file.c:75 sign-file: ./certs/signing_key.pem   XZ      /lib/modules/6.12.11/ethercat/examples/mini/ec_mini.ko.xz   INSTALL /lib/modules/6.12.11/ethercat/master/ec_master.ko   SIGN    /lib/modules/6.12.11/ethercat/master/ec_master.ko At main.c:171: - SSL error:FFFFFFFF80000002:system library::No such file or directory: ../crypto/bio/bss_file.c:67 - SSL error:10000080:BIO routines::no such file: ../crypto/bio/bss_file.c:75 sign-file: ./certs/signing_key.pem   XZ      /lib/modules/6.12.11/ethercat/master/ec_master.ko.xz   INSTALL /lib/modules/6.12.11/ethercat/devices/ec_generic.ko   SIGN    /lib/modules/6.12.11/ethercat/devices/ec_generic.ko At main.c:171: - SSL error:FFFFFFFF80000002:system library::No such file or directory: ../crypto/bio/bss_file.c:67 - SSL error:10000080:BIO routines::no such file: ../crypto/bio/bss_file.c:75 sign-file: ./certs/signing_key.pem   XZ      /lib/modules/6.12.11/ethercat/devices/ec_generic.ko.xz   DEPMOD  /lib/modules/6.12.11 Warning: modules_install: missing 'System.map' file. Skipping depmod. make[1]: Leaving directory '/usr/src/linux-headers-6.12.11'

This seems to the affect other command later like sudo modprobe ethercat. When this run it returns
modprobe: FATAL: Module ethercat not found in directory /lib/modules/6.12.11

Almost looks like the module never gets built or compiled correctly?
EtherCAT's kernel module (.ko) doesn't appear in the modules when trying to search for it
sudo find /lib/modules/$(uname -r) -name "ethercat.ko"

This returns not found

I think tomorrow I'm just gonna try everything again with an old kernel version, just to get started.

You could try this IO board which has an A/B encoder and I think a counter for MPG
vi.aliexpress.com/item/1005001454590369....gatewayAdapt=glo2vnm

Your drives should have a fault/error output ( you would configure an output for this in the xml file) and connect it to jount.n.fault-in
That way Linuxcnc will konw when a fault occurs.

Actually Tommy is was an interesting thing you raised, I had no idea of the different spellings & such. I think being in Australia and being so far away from the rest of the world we know that things are different outside the context of out borders.
Another thing is being a colony of the British Empire, and getting our independence without a war (they were probably happy to be rid of us), we still kept cultural links to Great Britain and later on had "the USA influence". And we have no issues with metric imperial system. But cmon the metric system makes more sense, doesn't have different values based on arbitrary values, geesh base 17 would have made more sense.
Tho it does piss me off that people at home call Solicitors lawyers, our political and justice system is based on the Westminster model, that when we have elections people think that like the US we vote for a leader, when in fact we vote for the candidate in our Electorate and whatever party gets the most votes win. Technically the leader of the winning party could lose his seat and said party would have to vote a new leader.

I don't use X but from limited experience of Facebook I think that is the epicenter of dumification (is that really a word lol). It replaced the viral emails of the late 90's and early 2000's, excpet it has a broader audience and the dumbness spreads quicker.

I having a conversation with a girl once and she thought she might be gluten intolerant, turned out she was eating 8 -10 slices of bread a day and feeling bloated.

There's more but I think I'll just go out and yell at the sky. I'm pretty sure that's what my son thinks I do all day......but he's a Metalhead so it's okay.
