Issue in iMX7D Power measurement

Hi, 

We are using imx7D SabreSD board with 'NXP i.MX Release Distro 4.9.11-1.0.0'. While we measured current consumption at measuring point F1(total), we got the following values.

activefreezestandbymem
322323270310

Note: All values are in mA.

And also we measured some power domains such as VDD_SOC, VDD_ARM, VDDA_1P8, NVCC_DRAM etc.., The values are given below.

Power domainsactivefreezestandbymem
VDD_SOC – R24159.8162.113.22.25
VDD_ARM – R205-1611.727.80.619
VDDA_1P8 - L5211910.1-0.5
VDD_LPSR_IN – R320.05760.05650.04650.0472
VDD_SNVS_IN – R311.3631.3630.32070.1758
NVCC_DRAM – R234639.6423.1914.97
NVCC_SD2 - R3250.02567.430.02560.0256
VDDA_ADC_1P8 - L81.2290.00070.00060.0006

The problem is total current consumption for mem(Deep sleep mode) and standby mode are greater than freeze state and active states while current consumption in other power domains are less in Deep sleep mode. We dont know which domains/pheripherals are consuming more current in Deep sleep and standby mode. Could anyone help us to find the domains which consumes more current in mem and standby mode.

 

Thanks in advance.
