In the meantime I found a set of pseudo-files such as:
/sys/class/hwmon/hwmon0/device/temp0_input
When I "cat" the file I get a sensible result (between 40 and 62 depending on the load). There are also temp<1 to 3>_input files, but a "cat" yields the same result whatever the index. I'm wondering if there are several temperature sensors inside the RK3288 - say one sensor for each core.
from TRM
The system has three Temperature Sensors, channel0 is reserve, and channel 1is for CPU, and
channel 2 is for GPU.
if your system is well stable(no or constant workload), it might report same values.
it's very hardware component(SoC) related sensor. it's not random temperature, not for different applications. |
