The current SDK has five default CPU profiles (400 MHz, 600 MHz, 800 MHz, 1000 MHz,and 1200 MHz). To manually set the CPU frequency, disable dynamic CPU frequency and voltage scaling byrunning the following command:$ echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Then set the CPU frequency by running the following command:$ echo 400000 > /sys/devices/system/cpu/cpu0/cpufr..
