LinuxCNC crashes on first run #1

Closed janbbeck closed 3 years ago

janbbeck commented 3 years ago

I just installed from the ISO, and then executed the Ethercat_installer.

Then, when running LinuxCNC, I get a crash report:

not sure where to go from here. The EK1100 Network lights did blink a bit while running the Ethercat_installer, FWIW

janbbeck commented 3 years ago

When running the ethercat install script in a terminal, it persisted long enough to grab some information. This may be relevant:

Job for systemd-modules-load.service failed because the control process exited with error code.
See "systemctl status systemd-modules-load.service" and "journalctl -xe" for details.

where "systemctl status systemd-modules-load.service" yields

janbbeck commented 3 years ago

I managed to solve this error by: sudo nano /etc/default/ethercat and manually enter the MAC address of the ethernet card of the computer at the very end of the file. For some reason this was apparently not detected. Then rerun the configuration by sudo update-ethernet-config After a reboot, linuxCNC starts.

Hope this helps someone.
