Hi Mike & Suzuki,
Sometimes user just want to have some quick test from PC with adb commands. It is very easy to reset all sources and sinks' status by command below. echo 1 > /sys/bus/coresight/reset_source_sink
Preparing the script for test is not easy for users who are not familiar with the coresight framework.
