Hi ,
     i have copied the dependencies that i have installed on TDA4 evm board and i have copied  the dependency to the TI board and i getting below error , i found the were this lock will create but in that folder(/var/run/lttng) no lock file is present.
lttng create my-kernel-session --output=/home/root/
Spawning a session daemon
Warning: Failed to produce a random seed using getrandom(), falling back to pseudo-random device seed generation which will block until its pool is initialized: Failed to get true random data using getre

The issue appears to be caused by failure to obtain peudo-random numbers 
with getrandom(), so there may be something missing on your system in 
that area. Running lttng-sessiond under strace may help figure out 
exactly how this is failing.

Also providing the output of lttng-sessiond in verbose mode would be 
helpful (lttng-sessiond -vvv).

Thanks,

Mathieu

getrandom() requires Linux 3.17 and glibc 2.25, this warning is common on old 
enterprise linux distros.
