I've a quad version of the UDOO running on debian Wheezy armHF on a 12V power supply and when I touch the heatsink, it seems a bit hot when the CPU is idle.. the ambient temp is around 28-30C ... I'm using the command below to check the temp and it gives me around 45C on average ... Code: cat /sys/devices/virtual/thermal/thermal_zone0/temp 1. Is this CPU too high for idle state ? 2. What are the commands to put the unused cores to sleep like on an Android phones ? Thanks
I would say that sounds about right . At this time in my room it is 18.4c , and my udoo is not total idle , but it`s running a firmata test script for the last day + 4 hours and webmin says 90% idle. my idle state is true idea !!!! , It`s Debian without any gui / server and scripts running. /sys/devices/virtual/thermal/thermal_zone0/temp - shows 46c I`ve tried compiling a kernel native and was monitoring the temp which stopped at 56c max , that`s with 100% all cores for nearly a hour.
