I'm curious to know how you built your image. When I try

Will share the .config later once I get on that machine.

Sorry, no I have not run cyclictest yet. The results are latencies
measured via gpio toggles from running the code posted previously.

Hi All,
I have built the realtime kernel using Yocto and deployed on the
beaglebone black (specifically core-image-rt-sdk). I have written a
program to test the timer latency and interrupt latency of userspace
