Q:
With LogicPD Linux BSP version 2.4-2, what is the default clock speed of the ARM core and DSP core setup to?
How do you change to clock setting?
A: This is documented in the Thermal Management white paper [1]. To see the current CPU frequency you can use cpufreq-info.
DM-37x# cpufreq-info
cpufrequtils 005: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: omap
CPUs which need to switch frequency at the same time: 0
hardware limits: 300 MHz - 1000 MHz
available frequency steps: 300 MHz, 600 MHz, 800 MHz, 1000 MHz
available cpufreq governors: conservative, userspace, ondemand, performance
current policy: frequency should be within 300 MHz and 1000 MHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 300 MHz (asserted by call to hardware).
cpufreq stats: 300 MHz:99.47%, 600 MHz:0.02%, 800 MHz:0.00%, 1000 MHz:0.50% (21)
For the DSP frequency, see table 2.2 in the Thermal Management white paper [1].
