Is their an internal core temperature sensor that Smart Reflex uses to determine the Adaptive Voltage Scaling of the processor? If so must it be enabled in the kernel or in u-boot? Cann its values be accessed, i was unabl to find a register in the TRM.
Technical Reference Manual:
There is a similar post with an external temperature sensor recommendation.
