Hi Denis,

After posting it crossed my mind to look at /proc/config.gz of the

THERMAL configuration variables you posted — thanks!
There’s a difference though in the available frequencies. On the
Debian kernel they go from 300 MHz to 1 GHz, where as with the yocto
kernel they go from 275 MHz to 720 MHz. Those are probably the
frequencies of the original BeagleBone.
Please take a look at your board .dts file and find the node
cpus/cpu@0/operating-points, where the frequencies/voltages are listed.
Full discussion of this subject references board revisions and two
techniques to set the operating points (TI does it in code, but it can
also be done in DTS). See details at

and related postings.
