ClearFog CX LX2 - What does « sensors » measure?

NXP LX2160

Hello,

I want to measure the power consumption of my ClearFog CX LX2, using the « sensors » command.

According to post Sensors terminal output , pout1 and pout2 actually measure the same power, but the reference is different.

My question is about what components are actually measured. From my understanding, pout1 is output-side power (Vout x Iout of the converter), excluding the converter’s conversion loss and the 12 V input path, and that it does not include DDR, SerDes, I/O, the module peripherals (PHY, USB hub, eMMC, SPI flash, clocks) or the carrier. Do you confirm ?

Thanks in advance.

Yes that is correct. It is only measuring the rail providing VDD to the main SOC. So that would include the SerDes controller, but not the devices attached to the SerDes, the network packet processing engine, all the I/O controllers that are part of the SOC, the CPU cores and the memory controller.
