hello, I use beaglebone black and install Linux Debian (*Linux beaglebone 4.4.6-bone-rt-r6 #1 PREEMPT RT Thu Mar 17 04:47:32 UTC 2016 armv7l GNU/Linux*), I want to test the characteristic of Real Time, so I use cyclictest:
After "*cyclictest -p 90 - m -c 0 -i 200 -n -h 100 -q -l 10000*", I got: *# Total: 000010000* *# Min Latencies: 00012* *# Avg Latencies: 00032* *# Max Latencies: 00053* *# Histogram Overflows: 00000* *# Histogram Overflow at cycle number:* *# Thread 0:* The result means the average latencies is 32 us. I wonder if it is normal or not? (In my opinion, it is a little wired, because with the RT-preempt patch, it should be better than it.) And if there is something wrong in the process, please tell me . Thanks so much. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
