Intel NUC NUC8i3BEK Hardware Watchdog iTCO Linux Error

Whenever I try to launch the Hardware Watchdog on my Intel NUC running 18.04 or 16.04 LTS Ubuntu I get:

(I am following this instruction http://www.madore.org/~david/linux/iTCO-wdt-test.html)

On my 7gen NUC with 16.04 it worked, but 8gen NUCs have this trouble. Glad for any help! Thanks

Hello JKipp,

 

Thank you for posting on the Intel Community.

 

I understand that you’re trying to launch the Hardware Watchdog on your Intel® NUC 8i3BEK.

 

Please allow me some days to investigate the behavior you’re experiencing, since the only operating system validated by Intel is Windows 10* 64-bit. You can check that information on the link below.

Also, have you tried posting this question to the Linux* forum of the distribution that you’re using? You may have answers from users that have encountered the same issue.

 

Thank you,

Hello Oscar_intel,

 

thank you for taking a look into this. The hardware watchdog is important for Intel NUC to be used as IoT device.

I have only checked linux forums on this an, but not posted it public.

I have tried out 16.04 LTS, 18.04 LTS Ubuntu, Yocto and Debian OS. All give the same error. 6+ months ago, I remembered testing it with an older Linux Kernel on 16.04 and it worked.

So mostlikely all kernels of the last 6 months and 18.04 don't work on Linux together with 8 Gen NUCs.

 

Thanks

Jens

Hi JKipp, We provide limited support for Linux* Operating Systems and most of the time we limit it to make sure that the OS runs fine. I have not tested this and we have no information about the error message reported. Did you report this error message to the owner of the guide: http://www.madore.org/~david/linux/iTCO-wdt-test.html ? Regards, Ronny G

Hi,

I understand. I have made a bug report to the linux kernel maintainers of itco_wdt. If you could test this on your NUC and also confirm this error. This would help. Thanks

Hi JKipp, I ran it and got the same "error message". If you get anything back from your bug report please let me know. Regards, Ronny G

I have the same problem with NUC8i5BEH. Neither iTCO_wdt nor wdat_wdt load correctly to create a working /dev/watchdog device. Can you issue a firmware update enabling watchdog device on Linux?

@vvidic​ Did you find a solution? Also on my Nuc8i5BEH the wdat_wdt loads without any output as error, but no watchdog device is created :-( See also my thread here on intel forum https://forums.intel.com/s/question/0D70P000006VRwX/nuc8i5beh-is-registering-itcowd-watchdog-wronlgy...

I have the same with NUC8i5BEH too ... and also opened up an own thread some time ago. https://forums.intel.com/s/question/0D70P000006VRwX/nuc8i5beh-is-registering-itcowd-watchdog-wronlgy...

 

The error matches to infos that can be found at https://www.spinics.net/lists/linux-i2c/msg41504.html where Linux Kernel devs analyzed the tpic and said that it needs to be fixed in BIOS from NUC.
