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)
Reducing chip T°
- Dynamic frequency scaling
- Using a mechanical passive dissipator: TBDL
