Power Calculation on IMX6 Sabre SD Platform Board

Hi everyone,


I have the "Sabre Platform for Smart Devices" demo board from freescale.


I would like to measure the power drawn only by the IMX6 processor on the demo board. By this means, I will have idea about power situation of our custom board that will be designed.


One idea was to turn the powers of the modules on the board off, but I could find no such way for that.


Second idea was to measure the power drawn by the external interfaces on the board but not the processor, hence, the difference between that value and the total value would give me the power drawn. For this purpose, I used the STOP mode of the processor, with, echo mem > /sys/power/state.


I want to learn whether I am on the right way and besides could there be any other way to measure the processor power.


Thank you very much in advance.
