Hi Chimeno,
Did you get ethercat with stretch working?
I was trying with stretch-amd64 and ran into problems.
I have it working with Debian Wheezy and 3.4.9-rtai kernel. The motherboard is using rtl8139 drivers and ethercat works well with panasonic A5 and A6 series drives.
When trying to upgrade to debian stretch, I am not able to patch the network drivers and the exact error message is:
applying patch 30_add_kernel-3.5.7_drivers to ./ ...patch: **** malformed patch at line 37097: _flagwork, (i

Do you have any how to guide or list of steps you used to get it working?
Regards,
-automata

Hello Automata,
I used the stretch version with core RT-PREEMPT, you have to use the "generic" driver, try to have it help you.

I used the preempt-rt amd64 kernel.
automata@stretchrt64:~/ecat/ethercat-1.5.2$ uname -a
Linux stretchrt64 4.9.0-3-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.30-2+deb9u5 (2017-09-19) x86_64 GNU/Linux
The only difference I am seeing right of the bat is you are using the i386 kernel instead of the amd64 kernel.
Still appreciate any guidance on getting this to work.
Trying with the i386 kernel with preempt-rt patch. Will report results soon.

hello Automata,
installed "strech RT-PREEMPT" from here?
www.linuxcnc.org/testing-stretch-rtpreempt/

Igh Ethercat Master configured "--enable-driver-generic"

So you used the generic driver all the time trying to sync your slaves?

Hi sirop,
Have you installed the Igh ethercat master on stretch with preempt-rt ?
Are there any other successful attempts (other than chimeno) at running the Igh ethercat master with debian preempt-rt kernel?

Actually, I use machinekit on debian 8 with xenomai, so kernel 3.8.

The official repo sourceforge.net/p/etherlabmaster/code/ci/default/tree/devices/ has adopted drivers 8139too for up to 3.16 kernel version.

The unoffical repo sourceforge.net/u/uecasm/etherlab-patche...default/tree/#readme has some device patches for up to 4.13 kernel version.
Please report if you succeed to use these patches.

hi Sirop,
If I use generic driver because I did not find for e1000e, is not it a good idea?

well, generic driver always means higher latency.
