Hi, 

I am measuring power in sabreSD board with kernel version 4.9.11. For Kernel version 4.1.15 the current consumption is close to the values given in the reference document https://www.nxp.com/docs/en/application-note/AN5383.pdf . For kernel version 4.9.11, the current consumption is little higher.

The table below shows the differences.

Linux-4.1.15

(mA)

Linux-4.9.11

(mA)

VDD_SOC – R241.422.25
VDD_ARM – R200.4670.619
VDDA_1P8 - L520.50.5

Is there reference document for power measurement with kernel version 4.9.11 ?

Do we need any power management steps for reducing power in version 4.9.11 ?

 

Thanks in Advance,

C.Senthilkumar
