Thanks, I've put a sample configuration file for your board at:

Hmm, this means that the absolute values returned by the coretemp
driver may be wrong. The relative value (difference between reading and
max limit) is still correct though. Rudolf, Huaxu, is this something we
have to live with, of can the coretemp driver be fixed?
