I have had to work on a project with a pc104 stack running yocto. I have had this since December last year and the image has always just randomly crashed 🤔. Yesterday I found out why!!
I am able to read the sensor of the cpu temp this has never been over 60/70 degrees C (yes I am English), however after running multiple tests and finally hitting my last wits I made the Kernel output over serial as no msg was shown on crash.
The company we have got the HW from always said this board won't over heat it throttles the cpu blag bla bla... And you guessed it in the mid of nothing but mess was a message "thermal_zone0 critical temp 127 degrees shutting down"
I didn't know if I was happy or about to cry as I didn't know if after working on this project for the last 6months I was back to the drawing boards as I need new HW or my gut at the start of not trusting the Company we are using!

Needless to say I have no idea what Monday will bring, I will keep you all posted as we all do care!

Much love

Jim
