Hi Zhang, Eduardo Our platform now is using thermal_zone, but lm-senser became no longer working. It works on non thermal_zone. we can get current thermal from /sys/class/thermal/thermal_zone0 on thermal_zone. What does lm-senser is doing ? and why it doesn't work on thermal_zone ?? -- thermal_zone enable patch -- a8b805f3606f7af7f2b44763d3d6cf05f7c15afd (ARM: dts: r8a7790: enable to use thermal-zone) -- lm-senser error on thermal-zone ---- > sensors No sensors found! Make sure you loaded all the kernel drivers you need. Try sensors-detect to find out which these are. -- thermal-zone / non thermal-zone situation -- non thermal-zon sensor command: OK read from /sys/class/thermal/thermal_zone0 : OK thermal-zon sensor command: NG read from /sys/class/thermal/thermal_zone0 : OK
