Can we disable 1 arm core for i.MX7D to save power using cpu-freq or something similar?

Hello Meet Thakkar,

You can manage the cpu frequency and status on /sys/devices/system/cpu/cpux where x is the number of the core.

You may then turn off the second core using something like:

echo 0 > /sys/devices/system/cpu/cpu1/online

I hope this helps!

Regards,

Apparently there was no change in power consumption. But taking a CPU offline did work.
