How to measure current/power usage

Hi everyone,

I’m trying to get a BeagleBone Black to use as little power as possible and I want to find a way to measure the current usage of the board. I found this blog post: about using i2c to communicate with the onboard power supply chip, but the post says that this method does not work with the newer BeagleBone images. Is there a way of using a similar method to find the current, that works with the newer images?
