How to compensate for CPU temp error on oPi0 LTS ?

[DoubleHP]

Hello; on OrangePi Zero LTS I have completely stupid values for CPU temperature. They were all reasonable for pre-LTS boards. I have read somewhere that this is a known bug. A kernel patch is probably available, but even if it's the case,I can not update my kernel. Where can I find the algorythm to compensate the value ? It's easier for me to fix the issue in userland code, rather than updating kernel.

 

How can I distinguish between pre-LTS and LTS boards ? Maybe MAC address for LTS are always in a given range ? I have a legacy board with MAC 12:42:98:f9:c8:XX, and a LTS with 12:42:3a:63:04:XX (unfortunately the LTS has a lower MAC :/ does not seem chronological )

Xulong never mentioned where they patched it even when asking:

They simply put out some more trash images and reverse engineering for that is just ridiculous...
