Hello Group,
I have the BeagleBone black running “Linux beaglebone 4.4.36-ti-r72” kernel. I am trying to read CPU temperature and PowerVR SGX temperature.
I face below issues:
- The entries in
/sys/class/thermal/thermal_zone*
do not exits.
# ls -l /sys/class/thermal/thermal_zone*
ls: cannot access /sys/class/thermal/thermal_zone*: No such file or directory
# ls -l /sys/class/thermal/
total 0
- sensors-detect results in external abort
# sensors-detect
# sensors-detect revision 6209 (2014-01-14 22:51:58 +0100)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Queries:
- Is it possible to read CPU temperature and SGX temperature in BBB? Is there any temperature sensor present on the AM3358 die or BBB board?
- Is there any LKM I can insert to get the temperature?
Thanks in advance.
