I am evaluating the power consumption of the imx.6 SoloLite using the Freescale evaluation kit.
I follow the Application Note 4580 "i.MX 6SoloLite Power Consumption Measurement".
in Deep-Sleep mode, I obtain a value very high comparing to the Application Note :
It concerns the rail VDD_SOC_IN + VDD_PU_IN, I obtain 5.4mW whereas the Application Note indicates 0.550mW !
The other measurements are normal.
My procedure to make the measurement is :
- Configure the Linux kernel to disable all Multimedia and Graphics drivers :
Device Drivers > Multimedia Support > OFF
Multimedia Drivers > Graphics Support > OFF
- Build "core-image-minimal" with yocto.
- Boot & put the system on deep-sleep mode executing :
$ echo mem > sys/power/state
- Measure voltage between pins of a resistance 0.020ohm soldered at SH3 to deduce the current of the channel, then the power consumption.
I think my process of measurement is correct because the other measurements I made are normal.
Maybe I need to configure something differently ?
Thanks for your help
