Measuring Power Consumed by iMX6Q Sabrelite

Hi all,


I'm using the i.MX6Q sabrelite board and would like to measure the power consumed by the chip. To be specific, I need to monitor the VDDARM_IN (CPU Power) and the VDDSOC_IN (GPU Power). Is there any tool provided by Freescale to perform this? The Power Consumption Measurement Application Note (AN4509) explains various use cases with their power analysis. The AN also mentions the power measuring points as R21 for VDDSOC, R27 for VDDCORE and SH17 for VDDHIGH. Unfortunately, these measuring points are for iMX6Q Sabre SD and not for Sabrelite. Also I couldn't find these measuring points on my board. If there's anyone from Freescale, or anyone who's familiar with power analysis out there, please help me out.


Thanks in advance,
