[etherlab-users] Working Counter is always 0

[Sam Chien]

Hi,

I have a big problem with TI AM3359ICE, the working_count still 0.

sam at debian:/opt/etherlab/bin$ sudo ./ethercat domain -v
Domain0: LogBaseAddr 0x00000000, Size   8, WorkingCounter 0/3
  SlaveConfig 0:0, SM3 ( Input), LogAddr 0x00000000, Size 4
    00 00 00 00
  SlaveConfig 0:0, SM2 (Output), LogAddr 0x00000004, Size 4
    00 00 00 00

That means slave doesn't answer the master, right??
when running the application, i get messages below

Do I miss some configuration??

In windows with twincat master, I can get digital input data and set
digital output to turn led on.


Any suggestion, thanks...
