CPUClock is a simple app that allows you to monitor the fast and slow CPU speed settings and to change these settings. It also gives a readout of the 'current' CPU speed (updated every second) as the OS switches between 'Fast' and 'Slow', depending on the processor loading.
CPUClock has been tested successfully
on the BeagleBoard (ARMv7/Cortex-A8/OMAP3 port). There are currently
issues on the various PandaBoards due to the OS port not yet being
complete.
Note that CPUClock is only of use on the BeagleBoard and similar modern hardware. It will not run on older hardware.
