<p class="MsoNormal"><font size="3" color="black" face="Calibri"><span style="font-size:12.0pt;font-family:"Calibri",sans-serif;color:black">Hi all,<br>
<br>
First appreciate the implement of etherlabmaster.<br>
I'm devolping a non-native supported ethernet device to be able to work as a RTDM EtherCAT master.<br>
What the device is one part of TI AM335x SoC and is named "cpsw".<br>
Everything smoothly while adapting driver code, building module file, and installing.<br>
But I was stuck by a problem when I try to start EtherCAT master.<br>
Following is my steps and message shown by dmesg:<br>
<br>
# /etc/init.d/ethercat start<br>
Starting EtherCAT master 1.5.2 done<br>
<br>
[ 30.849754] EtherCAT: Requesting master 0...<br>

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