After roughly went through Hikey's schematics, found BUCK1_1V05 is to power on ACPU's domain; so i'm trying to create hardware profiling enviornment for CPU's power consumtion on Hikey. Here i need some suggestions before can move forward:
- I searched schematics file, have not found there have on-board power measurement chip; so if Hikey has such current/power measurement chip, could you help point out? This will be much easier for us to do profiling (similiar with TC2 boards).
- If we need use external power monitor / power meter to measure the SoC's power, could you give some recommendation?  is a good one power monitor which i used before, but it's expensive (> 700$), so just want to check if have other better choices.
Thanks in advance, Leo Yan
