How to reduce power consumption in deep sleep mode in imx6dl?

[nayan_khant]

Hi All,

One customised board based on iMX.6DL processor, consume around 200mW power in deep sleep mode with Linux OS, is this admissible?

And also observe that PMIC (pf0100) does not get into STANDBY or SLEEP mode.

Please help me here, to optimize power consumption during sleep mode.

Thanks,

Nayan Khant

Thanks, igor for a quick response.

In i.MX 6DualLite Power Consumption Measurement document section 3.2.1 mentioned that in deep sleep mode VDDARM_IN & VDDSOC_IN should be drop to 0.9 volts (this should be done by PMIC).

But in my case, it remains as same 1.375 volts.

Any thoughts?

reason may be that your is not based on i.MX6DL NXP Sabre SD design spf-27392

schematic available on

Schematics (1)
Design files, including hardware schematics, Gerbers, and OrCAD files.
SABRE Platform for Smart Devices | NXP 

and not used nxp official bsp from nxp repository

linux-imx - i.MX Linux kernel 

One can try with i.MX6DL Sabre SD board and Demo Images from

Hi Igor,

I have checked the schematic against the i.MX6DL NXP Sabre SD design spf-27392, but I don't find major changes in the circuit. I have attached our schematic for your reference. Please check and let me know what are the other changes required to reduce the power of our device.

Thanks,

Hi Mrudang

one can test with i.MX6DL NXP Sabre SD design spf-27392

using Demo Images from

i.MX Software | NXP 

May be useful to check app notes:
