Is useful the watchdog when UP BOARD hangs at boot?

mlm82 New Member Posts: 3

Hi all,

I have a system that sometimes take a lot to boot up. It appears black screen and after a few minutes the system goes on. Other times boots instantly.

I'd like to know if changing the Watchdog setting in the BIOS from 300 to 15 seconds it may help to reduce the time that holds at startup. I've checked and it seems that the time with black screen reduces significantly, but I'm not 100% sure if this setting applies here.

Could it help?

Thanks in advance.

Best regards.

    Hi Sir

    The watchdog function will start when the system is turned on and will stop when the bios is handed over to OS.

    Could you please provide me more informations??
    What is your OS, kernel, bios version??
    Operate environment, such as temperature??

    Can solve this problem by replacing power supply??

    Best Regards,

    Thanks for your info about WDT behavior. I'll give you more details of our system as follows:

    • OS: Windows 10

    • BIOS: UP-CHT01 R2.3 (UPC1DM23) ( 8/17/2020) / Version 2.18.1263
    • Operate environment: occurs at ambient temperature.
    • Power Supply: custom battery based power solution, although I've experienced the same wit AC adapter

    The power system can't be changed by now.
