ALl the CPU clock changes when I try to update one of the CPU clock

I was trying to change the clock speeds of the CPUs manually using the following command (using super user):

echo <frequency> > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed

The above command should only change the clock speed of the cpu0. But it updates the clock speeds of all other CPUs to the same clock speed.

I am following the instructions on this site: Jetson/Performance - eLinux.org
