I’m looking for a way to measure CPU (and eventually GPU and CORE) power consumption at run time. I’ve a clamp meter which I use to measure board-level current. But I don’t see a way to conduct finer-grained power measurement (for example, at SoC level).
I’m using the AC power adapter (instead of a battery), so I don’t think that software tools like ‘powertop’ would work. Are there power consumption sensors at SoC level that can be accessed in some way?
