[Xenomai] Problem with Xenomai 3.0 Cobalt executing latency app

[Xenomai] Problem with Xenomai 3.0 Cobalt executing latency app

[Alvaro]

Good morning,
I 'm trying Xenomai 3.0 Kernel. I have compiled and encapsulated a 
preempt_rt_kernel from 
https://pixhawk.org/dev/ros/px4linux#rt_preempt_kernel that contains a 
Xenomai 3.0 with cobalt configuration on a Odroid C1 board. Afterwards, 
I downloaded the xenomai 3-3.0 files from your repository to install the 
libraries and the tools. I have compiled the libraries for Cobalt mode 
(./configure --with-core=cobalt --enable-smp --enable-pshared). When I 
execute latency application the system responses as: low init():binding 
failed: function not implemented. If I compile for Mercury mode when I 
execute the application latency I get: WARNING: [main] failed to lock 
memory .
BUG in xenomai_init(): [main] initialization failed, ENOMEM.

Could you help me?

Thanks in advance.

Hi,

"your repository" is a bit vague here. Which repository?

The most common reason for failing to lock memory is because you are
not running the application with root privileges. See:
