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:
