Linux HW Testing

As you would expect there are a lot of tools available for linux which can be used to test hardware. The following details some specifics.

lmsensors

Provides a sensors app which if your system is configured correctly will find and show data based on your sensors. Utilises /sys/class/hwmon to parse and find your sensors.

Yocto lmsensors recipe: http://git.openembedded.org/meta-openembedded/tree/meta-oe/recipes-bsp/lm_sensors?h=sumo

Also provides a daemon that can be configured to monitor your device so you can watch things over time.

Man pages give reasonable details on sensors and associated apps. https://www.systutorials.com/docs/linux/man/5-sensors.conf/
