  Hi 

  CPU-FREQ driver does seam to work when building your yocto image yocto-bsp_1v5 . 

  There's no cpufreq folder in /sys/devices/system/cpu/cpuX as expected. 

  I'had checked the kernel config and rebuild regarding section 2.3.3.2 of IMX Reference Manual Linux and tried default cpu governer ondemand and conservative but nothing change. 

  Do you have an idea what could be the cause ? Can you provide the config of your builded image based on Yocto ?

  Hi, 

  Machine config. files on github >https://github.com/ADLINK/meta-adlink-nxp/tree/hardknott/conf/machine

  I will check with our software team if CPU scaling was removed for any purpose.
