This page currently only apply to APF6 SOM, where multiple cores and video codecs/3D accelerators usage may require to monitor and control i.MX chip internal temperature.

Sensing chip T°

  • By default APF6 mainline and legacy kernels are configured with THERMAL infrastructure activated.
  • So you can monitor chip temperature (in m°C) with:
# cat /sys/devices/virtual/thermal/thermal_zone0/temp
37627

(here we see ~38°C on an APF6 Dual idle module)
