Setup problems #10

Closed LanderU closed 7 years ago

LanderU commented 7 years ago

Hello everybody!

I'm trying to deploy the master on CX9020 device, following the README instructions. I can create SD card without problems, but, when I start the init.d service, the output shows "done". But, when I check the service status, the output shows "dead".

Anybody have the same problem?

if you mean: /etc/init.d/etherlab start I see the same:

root@CX9020:~# /etc/init.d/ethercat start
Starting EtherCAT master 1.5.2  done
root@CX9020:~# /etc/init.d/ethercat status
Checking for EtherCAT master 1.5.2
Master0  dead

But kernel log looks fine, and running an example application should work, too.

As far as I can read from the init script it looks like the ethercat command line tool is used to determine the master state. But that tool is not include in the CX9020 example rootfs --disable-tool. So it would make sense to get a "dead" status, but having a fine master. If you manage to cross-compile the command line tool. Please, let me know. I'm pretty interested in the result.

Finally I leave the cross compilation way.

I have put all of necessary things inside the image and I'm able to compile natively.

Anyway, thanks for your help!
