After doing all of the steps mentioned in the following link,
the following error I am getting during testing on my C246P chipset based
industrial motherboard loaded with Ubuntu18.04.
$ sudo /opt/xenomai-3.1/bin/latency
0"000.000| BUG in low_init(): [main] Cobalt core not enabled in kernel
Is there any installation related issue and how can I resolve this issue?
I tried the same in my laptop loaded with Ubuntu 16.04, I didn't face any
issue and everything works fine. I am also checking with a laptop loaded
with Ubuntu 18.04.
I am totally confused that this issue is with the motherboard or Ubuntu
