I followed the instruction untill the reboot, so Etherlabmaster installed, and got no errors. see logging in the atachement.

however, if I now type =10ptethercat master, i get 'command not found':

wesley@wes-lcnc:~$ ethercat master
bash: ethercat: command not found

Do you have any idea what could be wrong or how to debug this? I already checked the .local files

=10ptThanks for any response,

Wesley

 

Thanks for writing this down.

After following the instructions until reboot, the command 'ethercat' is not found. So i do first

$ sudo systemctl start ethercat

as in the instruction of the etherlabmaster github. But then I get the following error:

Failed to start ethercat.service: Unit ethercat.service not found.

as far as I can see, the installation was succesful. Does anyone know what to do next or how to troubleshoot this?
Is it because I haven't connected the ethernet cable yet?

Thanks in advance for the help,

Wesley
 

I think the make setup command went wrong so I did that again and it looks like a file is missing; /sys/class/net/eth0/address:
;

wesley@wes-lcnc:~/etherlabmaster$ make setup
>>> We've found the local configuration file.
    The original ETHERCAT_MASTER0 = enp0s25
    will be overriden with ETHERCAT_MASTER0 = eth0

>>>

---

ECAT_SYSTEMD_PATH : /opt/etherlab/lib/systemd/system
ECAT_CONF_PATH    : /opt/etherlab/etc
ETHERCAT_CONFIG   : /opt/etherlab/etc/ethercat.conf
Cannot find device "eth0"
>>> Setup the systemd dkms.service in /etc/systemd/system

cat: /sys/class/net/eth0/address: No such file or directory

>>> We could find eth0 with the corresponding mac address
    Please check your system properly.
    For example, one can define it via

    echo "ETHERCAT_MASTER0=eth0" > ethercatmaster.local

wesley@wes-lcnc:~/etherlabmaster$ echo "ETHERCAT_MASTER0=eth0" > ethercatmaster.local
wesley@wes-lcnc:~/etherlabmaster$ make setup

Th forum sticky will also work for  the Pi (I have done it)
You might need to use a Raspberry specific descriptor for keys and sources.list based on their repo.  build.opensuse.org/project/show/home:bon...hes:science:EtherLab
