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 – R24 | 1.42 | 2.25 |
VDD_ARM – R20 | 0.467 | 0.619 |
VDDA_1P8 - L52 | 0.5 | 0.5 |
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
Hi Senthilkumar
I am not aware of power measurements with kernel version 4.9.11,
but document describes why power data may vary, please check
sect.3.2.1. ODT settings, sect.3.4. Temperature measurements
AN5383 i.MX 7DS Power Consumption Measurement
https://www.nxp.com/docs/en/application-note/AN5383.pdf
Best regards
igor
