Hi Per I should have documented this : rtdmnet.ko use RAW packet socket.
Don't forget to build and load rtpacket module to make it available. Hereafter are commands I use to run a test with rt-FEC driver: modprobe rt_fec modprobe rtpacket rtifconfig rteth0 up cat > /etc/sysconfig/ethercat <<EOF MASTER0_DEVICE="ff:ff:ff:ff:ff:ff" DEVICE_MODULES="rtdmnet" EOF /etc/init.d/ethercat start ethercat slaves Cheers, Edouard On 14/11/2018 17:03, Per Oberg wrote: > Hi > > I tried this today, but I ran into some troubles.
