Dear Henrik, First goal is to get a clean system setup.
IgH supports OpenSuse system from the official side (Packages are available under https://build.opensuse.org/project/show/science:EtherLab) I, a member of the IgH, supports Debian privatly. Ubuntu is known to run, but it maybe it is more complicate than the other system. I have created some Raspberry images with Etherlab preinstalled on the standard kernel Have a look at https://www.stewering-bone.de/index.php/s/R7MME7b5Yf7B83x That are images like the official raspberry images, please read the official documentation how to install it. I have created a Debian live CD for x86 system with RT-Kernel, rt-test tools and EtherLab preinstalled. It can be used with or without installation. Have a look at https://www.stewering-bone.de/index.php/s/R7MME7b5Yf7B83x It is based on the debian live projekt, for further informations see https://debian-live-config.readthedocs.io/en/latest/ To get the EtherCAT master running: - Get the MAC of your interface via ip a - You only have to modify /etc/ethercat.conf, Add MAC and select generic driver - Start the master via sudo systemctl start ethercat - Check bus via sudo ethercat ma and sudo ethercat sl Second step should be write and run a minimal c example to access the bus, see the ethercat master examples Third step is to get matlab running, but this is a little bit more complicated. Any ideas, fixes or comments on the created boot images are welcome. The software to create the images is hosted under Raspberry: https://gitlab.com/igh-ab/pi-gen Debian-Live: https://gitlab.com/igh-ab/debian-live-config Best regards Andreas Am Dienstag, dem 27.09.2022 um 17:38 +0200 schrieb Henrik Barie: > Hello Andreas, > > when using "dmesg" I dont get any EtherCat-related messages. > Usually the last messages are something with EtherCat but this time > there are none. > I dont know how to run the Master with the standard kernel. > Im using Ubuntu 22.04 with a Realtime Kernel in a Beta-Version.
