Hi,

Would it be possible to get some information regarding how to monitor CPU temperature and clock speeds of the RK3399 running Ubuntu?  The usual lm_sensors solution doesn't seem to work.

Thanks,

-Karl

Found what I needed:

  1. cat /sys/devices/system/cpu/cpufreq/policy?/cpuinfo_cur_freq /sys/devices/virtual/thermal/thermal_zone?/temp
Copy the code


I'm assuming that thermal_zone0 is the CPU.  thermal_zone2 looks like it's in different units, and perhaps not connected to anything.  Any clues as to what thermal_zone1 is?
