Hi,
Currently I have Fedora Linux with Kernel version 2.6.19, with RealTek
RTL8139 NIC. And I have downloaded Ethercat 1.3.2 from etherlab.
I am able to compile the code and start it; Apart from starting I am not
able to do any thing. Below are the only three lines in the
/var/log/message file. Can you please help in finding the issue, what is
causing this
Jul 2 10:31:01 localhost kernel: EtherCAT: Master module cleaned up.
Jul 2 10:31:12 localhost kernel: EtherCAT: test -- Master driver 1.3.2
stable r980
Jul 2 10:31:12 localhost kernel: EtherCAT: 1 master waiting for
devices.
Thanks,
Pavan

Hi there!
Yesterday, shortly before r1303 has been announced, I've tried r1272 and
then r1303. With both versions, there's the problem of timed out
datagrams. By going back to r1174 it works again.
I've tried with the realtek and the e1000 card, which made no
difference. Running kernel is 2.6.22-rtai on Intel P4 (2.4
Ghz). Operating system is Debian(Ubuntu)-Linux.
Here's the output from /var/log/messages

The loss of datagrams is resulting in missing devices. But it changes by
every start of the master, so that's not symptomatic for a certain
device type. Sometimes only data of one device is missing, but most
more.
