Overclock raxda zero 3w

#1

hi everyone, anyone know how to overclock raxda zero 3w with RadxaOS? i write down what I found for now:

  1. dts located in /usr/lib/linux-'uname -r' are 3 for zero 3w
  2. U-Boot parameters set the rk3566-radxa-zero-3w-aic8800ds2.dtb file in boot environment
  3. dtb file is potentially setted for 1.8 Ghz but the limit in /sys/devices block is 1.416 Ghz
  4. using all cpu tools and commands like cpufrequtils, cpupower, cat via terminal and so on,the frequency still on the 1.4 Ghz

now i’m stucked on what to do, please help me to find a solution or new ideas

Hi ciapciap ,

Because we disabled the high frequency of the CPU for rk3566-T in the driver. So you can’t make the CPU work in high frequency mode by commanding and modifying dts.

can i modify driver through kernel development/compiling? can you indicate me the files or libraries in question?
