Issue with Linux watchdog timer where system did not restart.

Issue with Linux watchdog timer where system did not restart.

Hello,

I have a motherboard NUC7i7DNB version, J83500-206 BIOS version DNKBLi7v.86A.0070.2020.0924.1014.
I am using it under a Linux system.
I want to use the integrated watchdog:
iTCO_wdt: Intel TCO WatchDog Timer Driver v1.11
iTCO_wdt: Found a Intel PCH TCO device (Version = 4, TCOBASE = 0x0400)
iTCO_wdt: initialized. heartbeat = 30 sec (nowayout = 0)

Unfortunately despite all my tests this one never increments and the value of timeleft remains constant.
(cat / sys / class / watchdog / watchdog0 / timeleft)
Which has the effect of never causing a restart of the card.

While browsing your forums (https://community.intel.com/t5/Processors/Using-linux-iTCO-wdt-driver-on-i3-7100/td-p/1126815), I saw that users had completely corresponding phenomena on the NUC7i3BNK, NUC7i3BNH, NUC7i5BNK, NUC7i5BNH,
NUC7i7BNH range. It would appear that the problem has been resolved by updating BIOS (version 0083) (https://downloadmirror.intel.com/29783/eng/BN_0083_ReleaseNotes.pdf?_ga=2.34077857.1832265243.160977...)

Can you proceed to the BIOS update for the NUC7i7DNB range, so that the Intel PCH TCO Watchdog can be used.

Thanking you,

Sincerely,

Paul Goulpié

Please update your system BIOS and let us know the results.

Hello DeividA_Intel,

Thanks for your feedback.

I just tested the latest version of the bios (DNKBLi7v.86A.0073.2021.0414.1709), and I confirm that the problem is solved. The card now restarts correctly after expiration of the timeout.

Thank you very much for your efficiency.

Sincerely, 

Paul Goulpie
