Hi,
somewhere i read this thing should have an internal temperature sensor.
Any info on that available beside this piece in the linker file?
Code: Select allPROVIDE ( rom_abs_temp = 0x400060c0 );

I have not seen anything about an internal temp sensor. Their demo boards have this chip on them and support for it is in their IoT SDK

My experience with built-in temp sensors is that they are fairly useless for reading ambient temperature. What they are useful for is when the chip is in a hostile environment. You can use the on-die temp sensor to watch the die temp. Then if the chip is about to fail from over heating make changes in the system (change a duty cycle, turn on a fan) to keep the chip running.
