Temp was correct running Armbian before DietPi install

MichaIng · 2023-05-13T15:36:44Z

If Armbian shows the temp somewhere, then it is obtained with a different mechanism.

Which SBC exactly do you use? And can you show the output of:

for i in /sys/devices/platform/coretemp*/hwmon/hwmon*/temp*; do [[ -e $i ]] && echo "$i : $(<$i)"; done

its a generic S905 1g/8g box "uses gxbb-p201 device tree"

no output with that command "no coretemp folder"

MichaIng · 2023-05-15T17:48:12Z

Ah sorry, wrong command, please repeat with this one:

for i in /sys/class/thermal/thermal_zone[0-9]/temp /sys/class/hwmon/hwmon[0-9]/temp[0-9]_input; do [[ -e $i ]] && echo "$i : $(<$i)"; done

generic S905 1g/8g box

It is using the Armbian meson64 "current" kernel, Linux 6.1?

uname -a

Black6spdZ · 2023-05-15T18:05:06Z

/sys/class/thermal/thermal_zone0/temp : -1000
/sys/class/hwmon/hwmon0/temp1_input : 4294967295000

Linux DietPi 6.1.27-ophub #1 SMP Mon May  1 13:03:40 EDT 2023 aarch64 GNU/Linux

MichaIng · 2023-05-15T18:14:32Z

6.1.27-ophub

This does not look like an Armbian kernel. Which base image did you use before running the DietPi installer? Or which kernel package did you install? In case you do not know, this should show it:

dpkg -l | grep linux

None of the two only available sysfs sensor nodes report something useful. -1000 is of course rubbish, 4294967295000 might be just an unusual unit, I thought, but actually there is no power of 1000 giving a reasonable value:

4294967295000 / 1000 / 1000 / 1000 / 1000 ~= 4.29

42 °C would have been a value that makes sense, 4.2 °C however not, and 10 picoseconds won't be the unit. So if this did work on Armbian, then either with an older kernel version (probably Linux 5.15 which got upgraded to 6.1) or not using sysfs at all. Does this return some reasonable value?

apt install lm-sensors
sensors

This is not something we would implement but take it as broken sysfs hwmon API for this particular board, but at least you would have a tool to get the actual value then, or at least one where you can observe temperature changes, while I wouldn't trust the absolute value.

how do I see where they pull the temp from?

Black6spdZ · 2023-05-15T19:15:44Z

this thread seems pertinent https://forum.khadas.com/t/thermal-reading-wrong/168/20

I tried to break into u-boot to issue that SARADC command but appears no USB keyboard support

from what I understand is that the dtb used doesn't have the adc support?

MichaIng · 2023-05-18T16:43:44Z

Jep, what you linked seems to match, so interestingly an issue on mainline kernel as well as vendor kernel.

Check out the steps I posted above to see whether this returns a sensor with the same temperature as Armbian shows it in their login banner:

apt install lm-sensors
sensors
