Thank you, that seems to have fixed the issue. The entire xeno-test script completes and the latencies seem to be very good. I assuming that this is just because the board does not have enough horsepower to run the test at 100 us? I'm new to this so I'm trying to learn as I go. Is there any specific condition where I would not want to enable the ARM TSC support?
