Up Core will not boot unless it is reset manually.

ddd2 · July 2020

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 5V@5A 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?

@dd2
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.

Hi @rogertsai(AAEON) , were can we get that information?, is it on the sticker on top of the computer?. We do not have the computer at our disposal but we will send this info as soon as we can. Thanks

@ddd2
For UP core board, you should be able to see a S/N label on the side of the heatsink

Hello ! I have exactly the same problem. I am working with UAVs with embedded UP Core. On each of my UAVs, time to time, the onboard computer fails to boot (no message on screen if I try to display in HDMI). It is very annoying because I have to unplug and plug back the battery until it boots. My BIOS is up to date with the latest version (2019).
Does anyone have a solution ? @ddd2 Did you solved your problem ?
