Cubietruck SoC temperature vanished

[Homoran]

Hi to all,

sorry if it is already described anywhere.

I found some similar issues but no solution, except ...has to be modified.. or anything similar.

 

Two days ago I updated my Armbian Jessie server on may Cubietruck with

 apt-get update && apt-get upgrade

 

After that my homeautomation didn't show the SoC temperature any more.

 

first I looked for an error in the software, then after a lot of reboots I noticed the temperature also missing in the armbian startscreen.

 

 

The command

cat /sys/devices/virtual/thermal/thermal_zone0/temp

was responsed by

cat: /sys/devices/virtual/thermal/thermal_zone0/temp: Invalid argument

a commit of tkaiser I found at github (Adjust thermal readouts)

but it didn't really help me

 

even the Armbianmonitor says:

cubie@ioBroker-Cubie:~$ sudo armbianmonitor -m
Stop monitoring using [ctrl]-[c]
Time        CPU    load %cpu %sys %usr %nice %io %irq   CPU
18:25:43:  864MHz  2.75  34%   4%  22%   0%   6%   0%/usr/bin/armbianmonitor: line 274: read: read error: 0: Invalid argument
/usr/bin/armbianmonitor: line 275: [: -ge: unary operator expected

 

 

It was working fine for months:

 

 

Thanks for any help

Well, you are using bleeding edge kernel v4.10.12 which can be found only in self build or nightly images. Not recommended for production usage, even tagged with "stable". It looks like regression in kernel - I also noticed.

 

I am sure this will be solved when possible.

I see 4.10.12 in the stable repository for some reason. Did you push an update accidentally? apt.armbian.com file timestamps are 27 Apr

Upps. I recreate the repository that day and added hostapd ... this kernel fall in by mistake

As Zador.blood.stained mentioned.

I didn't do any such things ;-)

I made new repository handling scripts and those two files were added for testing purposes but I forgot to remove them ... well, I'll fix this. Sorry for troubles.

No Problem!

 

So I will revert this by doingt apt-get update && apt-get-upgrade again?

Or will I have to do something else?

Yes, only that.

[Homoran]

Thanks a lot!

No. Once repository is fixed you will need to remove and reinstall the kernel (obviously without rebooting)

Downgrade won't be forced if installed package version is higher than in the repository.

Ofc. Previous packaged version is 4.9.7 ... now I am trying to find out when temperature stopped working ... I know it's probably more than that, but what is the best way to go from such case? Simply reverting to 4.9.7 with new package version or invest some time?

 

4.9.25 has broken temp reading too. That's all I found out.

[zador.blood.stained]

I remember there were updates related to a conflict between the touchscreen driver and the thermal driver, so after we switch to 4.11.x I'll check the kernel config and will make some tests.

[Homoran]

Just to ask, is there a solution in sight.

 

Thanks again

Hello everbody.

Well, it seams that I have also managed to upgrade to 4.10.12 but didn't saw until now that temperature is missing. How to downgrade or "update" to the last version in repository if it is lower then installed? Tried downgrading with the script mentioned in other posts but no luck.

 

zvone@orangepi:~$ wget -q -O - http://upgrade.armbian.com | bash
bash: line 1: syntax error near unexpected token `newline'
bash: line 1: `<!DOCTYPE html>'
zvone@orangepi:~$

To answer to my self, in case someone has the same problem and same lack of experience.

 

First remove kernel package:

sudo apt-get remove linux-image-next-sunxi

 

This removes v4.10.12, and then (no reboot), install same package (at the moment this installs v4.9.12):

sudo apt-get install linux-image-next-sunxi

 

After reboot I have CPU temperature reading.
