I am currently trying to measure the core power on Raspberry PI/PI 2. I have successfully integrated gator daemon, driver and DS-5 Streamline for PI. In the list of counters, I can see events related to Cache misses. However there is no power related counter available. on DS5 I would like to know if there is a way to measure core power on PI/PI 2.
Hi,
You need to purchase the ARM Energy Probe and have it connected up to your target and also to configure Streamline to use it in order to use any power-related counters.
See ARM Energy Probe | ARM DS-5 Development Studio and also the Streamline User Guide, Chapter 11, "Capturing Energy Data"
I hope this answers the question as to why you cannot see any power-related counters.
Regards,
Stuart
