Hello, I have problem with setting cpu freq to 1 GHz. I'm using OSD335x RED board. I downloaded latest Beaglebone image and installed different kernel. I need to use UIO driver which is not present in latest kernel. root@beaglebone:/# cat /etc/dogtag BeagleBoard.org Debian Image 2018-03-09 root@beaglebone:/# uname -a Linux beaglebone 4.4.120-bone22 #1 Tue Mar 6 23:59:09 UTC 2018 armv7l GNU/Linux root@beaglebone:/# cpufreq-info cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to [email protected], please. analyzing CPU 0: driver: cpufreq-dt CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 300 us. hardware limits: 275 MHz - 720 MHz available frequency steps: 275 MHz, 500 MHz, 600 MHz, 720 MHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 275 MHz and 720 MHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 275 MHz (asserted by call to hardware). cpufreq stats: 275 MHz:98.68%, 500 MHz:0.07%, 600 MHz:0.07%, 720 MHz:1.18% (18) Setting frequency via cpufreq-set -f has no effect. I already tried to use DC power supply, but same result. I found that different kernels has different settings. Is it possible to change dts to fix it and force cpu to run @1 GHz?
