How to reduce the power consumption for imx6 sololite processor

[sivakumarganesa]

Hi,

In our project we used imx6 sololite processor based board. below i have mentioned processor with our board condition.

1) processor running speed 800MHz

2) wifi and Bluetooth enabled

3) camera enabled

4) Display enabled

Quires

1) what are the ways to possible to reduce the power ?

2) what is the minimum processor clock frequency required to run the above mentioned peripheral?

3) How to reduce the processor clock speed from 800MHz to 400MHz?

now our board consuming 3.7V@450mA. Also board getting very hot during on condition.

Please help to reduce the power consumption for the same.

Thanks & Regards,

Sivakumar

Hi sivakumar

methods for reducing power consumption are described in

AN4580 i.MX 6SoloLite Power Consumption Measurement

sect. 4 Reducing Power Consumption

http://cache.nxp.com/files/32bit/doc/app_note/AN4580.pdf

At boot one can use selection:

BT_FREQ(BOOT_CFG2[2])=1 - ARM - 528 MHz, DDR - 307 MHz, AXI -176 MHz

Best regards

igor

Hi igor,

Thanks for replying me. We are using Freescale provided Linux kernel (poky distro). In Idle mode, is there anything specific we can do in the Linux kernel to reduce the power consumption and hence decrease the heat generated.

Thanks,
