[etherlab-users] EtherCAT: Failed to read number of assigned PDOs.. timeouts

[Soo-Hyun Yoo]

Hello,

We have four EtherCAT slaves connected to an EtherLab master service running
on an MSI nettop. This is our configuration:

   - Ethernet card: Realtek 8169
   - OS: 32-bit Xubuntu 10.04
   - Kernel: 2.6.32.11 with RTAI patch
   - EtherLab: revision 2060
   - EtherLab configuration: --with-linux-dir=/usr/src/linux
   --with-rtai-dir=/usr/realtime --disable-8139too --enable-r8169

When we connect the slave cards to master, this is the output in dmesg:

What could be causing these timeout errors?
