Hi! I'm using the v3.8.x branch from RCN with a BBB clone based on am3352 with 800MHz factory rate. I can see that under heavy load the frequency goes up to 1GHz while it should be limited to 800MHz. Can anybody suggest a way to limit the frequency in the kernel?
I did some testing and setting the cpu frequency with the below command does limit it. Using sysfsutils and editing /etc/sysfs.conf to include these lines: devices/system/cpu/cpu0/cpufreq/scaling_governor = ondemand devices/system/cpu/cpu0/cpufreq/scaling_max_freq = 600000 sets the frequency at bootup. However the cpu still runs at 1GHz for a few seconds before these settings take effect, so I think we need a kernel change to fix this -- LinkedIn - http://www.linkedin.com/in/maximpodbereznyy Company - http://www.linkedin.com/company/mentorel Facebook - https://www.facebook.com/mentorel.company -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
