Xenomai (master/next) unable to use orocos-corba

Xenomai (master/next) unable to use orocos-corba

[John Ho]

Hi all, I apologise for posting this again, but i was testing some stuff
with xenomai and orocos, and i am not sure if i have encountered a wall
with my progress. With special thanks to Gino, I was able to get the i219v
drivers patched and rtnet running. As such I was able to get information
from my Ethercat slaves on my university's robot.  I installed orocos 2.9
with a custom branch of rtt from rtt-lwr. Although I was successful in
compilation, and was able to use deployer-xenomai, I encountered an issue
with deployer-corba / deployer-corba-xenomai. It only displays the memory
available and nothing else.

After changing the branch of xenomai to stable-v 3.0.x or even v3.0.10, I
was able to start deployer-corba-xenomai/ deployer-corba again. I am not
sure if it is something to do with my kernel configuration that is causing
this issue or something else.

I will greatly appreciate any help I can get with this regard.

Hi John,

I am not familiar with orocos, if it is in ROS releated stack, does it
already using Preempt-RT Linux kernel as realtime solution?

Hi Gino,

I understand, but thank you so much for the help thus far! I guess I have
to see if there is any other ways to communicate with my other pc! But
still being able to communicate with the EtherCAT slaves over RTNET was a
major turning point for my project!
I will try to ask the other website to see if they know anyway to resolve
this issue!

yours sincerely,
John
