Hi Andre,
I had a similar issue.
I reverted 2 commits (changesets):
changeset 2117: "Removed allow_config flag and obsolete request to OP."
changeset 2100: "Improved DC sync at startup: Abort iterating though
slaves and first correct"
I think especially changeset 2117 one might also be responsible for your
problem.
Changeset 2100 causes problems on my machine especially when I (re)start
EtherCAT master.
I didn't investigate the root cause of the changeset problems on my
machine,
because reverting the changesets solved it on my side.
Nevertheless EtherCAT master source runs very fine. Thanks a lot to all
developers for their great work!
(We currently develop a motion control solution based on: RT-PREEMPT
(2.6.33) and our Toshiba TX4938 (mips) based motion hardware MCU-3100)
regards,
Ralf
Hi all,
I am working with latest Ubuntu Natty 11.04 64bit 2.6.38-11-generic kernel
and the generic driver built from the latest mecurial sources.
Four slaves are connected to the bus, which I have verified temporarily
plugging in a different machine with ethercat running.
I built ethercat with
./configure --enable-generic --enable-cycles --disable-8139too
Just as a side note, I had to create a symlink in the kernel images to
make it compile
cd/lib/modules/$(uname -r)/build/include
sudo ln -s $(gcc -print-file-name=include)/stdarg.h
Seems like this is a general Ubuntu issue,
seehttps://bugs.launchpad.net/ubuntu/+bug/830550/comments/1
Then, everything built fine.
sudo ethercat master
now gives me

Unfortunately, sudo ethercat slaves does not show anything (there are
definitely four connected to the bus).
However, log messages indicate that there is some kind of connection at
least.

Just for your information, here is also ifconfig (the ethercat cable is
attached and configured to the eth0 card)

Note I have also tested configuring the other network card in the same machine,
with the same result.
I believe the bus scanning is for some reason not working.
Your help is greatly appreciated.
Best regards,
Andre
