Is there any way we can configure IMX6Solo at 400Mhz

[Yogee]

Hi,

We need to understand how IMX6S would be configured at 400Mhz to make the system at lowest power. LPDDR2 used would be configured at 333Mhz.

I think you can just use the powersave governor for cpufreq driver, then cpufreq will be fixed at 396MHz.

echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governor.

Hi, Yogee

you can refer to i.MX_6Solo6DualLite_Linux_Reference_Manual.pdf.

Maybe you can adopt other methods to realize the objective of low-power consumption. And for example, Low-level Power Management driver on Linux.

As far as i know, IMX6Solo hardware supports four low-power modes: RUN, WAIT, STOP, and DORMANT , you can make the CPU run under these low-power modes.
