Hi all,
I was running Ethercat master with Gavin’s patchset older hardware with R8169
driver with Preempt RT. But new hardware is using I225 (Ethernet controller:
Intel Corporation Ethernet Controller I225-LM (rev 03)), igc driver, and newer
kernel with Ubuntu 22.04. Unfortunately, I am unable to run with igc driver
with Kernel 6.4. But, generic driver works. I tried to compile my RT kernel and
Ethercat master a few times with different configurations, but no luck. I
slightly suspect there might be an issue with this new driver patch. Any help
you can give would be appreciated.
Here is my dmesg log. (Driver looks like loaded ?)
[ 8167.603308] EtherCAT: Master module cleaned up.
[ 8169.698759] EtherCAT: Master driver 1.5.2 unknown
[ 8169.699063] EtherCAT: 1 master waiting for devices.
[ 8169.743069] Intel(R) 2.5G Ethernet Linux Driver (EtherCAT enabled)
When I select igc driver from /etc/sysconfig/ethercat, master is not works. But
with generic driver it finds my Ethernet chip. No slaves connected.

Also you can check “lsmod” data for both generic and igc here:
