What is the best way to get the CPU temperature from the command line? The typical sensors from lm-sensors doesn’t work. I can get it externally with a thermocouple, but I’d like it from the command line too.
Thanks,

There is no temperature sensor in the U540 chip or on the unleashed board. Sorry. 
If you want to use an external sensor you’ve attached, you presumably need to add support for that device in the kernel before lm-sensors can use it.
We’re going to measure externally for now with a Fluke and a thermocouple. Here’s a drawing:
