Hi Ajith,

Use cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

Hi,

I did cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq it is showing 720000. Which means 0.72MHz

I feel that is very low. Generally it should in around 500 MHz.

Please suggest me in this regard.

Hi Ajith,

This actually means that your processor is running at its highest frequency 720 MHz (OPP100).
