[etherlab-dev] "Master still waiting for devices!" problem.

[周甫霖]

Hi all,

First appreciate the implement of etherlabmaster.
I'm devolping a non-native supported ethernet device to be able to work as
a RTDM EtherCAT master.
What the device is one part of TI AM335x SoC and is named "cpsw".
Everything smoothly while adapting driver code, building module file, and
installing.
But I was stuck by a problem when I try to start EtherCAT master.
Following is my steps and message shown by dmesg:

# /etc/init.d/ethercat start
Starting EtherCAT master 1.5.2  done

[   30.849754] EtherCAT: Requesting master 0...
[   30.854265] EtherCAT ERROR 0: Master still waiting for devices!

More information:

Could anyone kindly advice what is the key point to go forword form
"waiting device"?
