Creating timer thread failed on Xavier

[arirang2067]

I using Robotis-Framework on Nvidia Jetson Xavier.
When I try to control Dynamixel through the Robotis-Framework, I get the following error:
[ERROR] : Creating timer thread failed!!
I used 'sudo bash' and the code was compiled with catkin_make by gcc ARM aarch64.
I also ran sudo bash -c 'echo "@xavier-rtprio 99"> /etc/security/limits.d/xavier-rtprio.conf'.
The same code works fine in the normal pc environment of ubuntu16.04.
How can I resolve this error?
