Sometimes you might want to control the clock speed of the BeagleBone. For example in a battery-powered environment where you want to use as little power as possible, and thus want to set the BeagleBone to use a lower frequency clock speed.
In the later BeagleBone demo images, this can be done by using cpufreq-set.
Read frequency and what governor that is used:
The governor can be set to any of the values "conservative", "ondemand", "powersave", "userspace".
The minimum and maximum frequency that the governor can use, can also be set.
The frequency values that can be used are "720MHz", "600MHz", "500MHz" and "275MHz".
When the "userspace" governor is used, the information is also available on the file system:
Read current speed:
Set speed (275MHz, 500MHz and 720MHz):
