Up Core will not boot unless it is reset manually.

We are working on a Up Core based embedded system. From time to time the computer will not even boot unless the reset button in pushed for a while. This is concerning because this requires us to recall the deployed system. And because of the placement of the reset button in the system we have to fully disassemble it.
We are using a filtered [email protected] power source and the system is properly ventilated as we can see that the working temperatures are really stable. We are using the fan heat sink.

This problem happened to us with the UPBoard as well. We have noticed that one of the first recommendations on this forum is to properly mount the heat sink but ours seems to be correctly assembled.

We would like to know what is the proper way to prevent these soft locks, what might be causing them and or even how to properly exit them or how to troubleshoot them. We are clueless about what is happening.

Thank you in advance,

Can you check if you have the latest BIOS on your UP Core?

What operating system are you using?

Can you please provide me with your Part number & Serial number so that i can have a look about the UP record
e.g. Part number:UPC-CHT01-XX-XXXX; Serial number:CXXXXXXXX

Hi @DCleri , the BIOS was in fact not updated, we are currently on UCR1BM10. We cannot access the system right now but we will update it ASAP. We are using Ubuntu 18.04 as OS. Thank you for your help, we will report back.

For UP core board, you should be able to see a S/N label on the side of the heatsink
