Watchdog settings via EVOK

smontosa

Hi.
On Debian Buster, at version:

dpkg -l evok
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version      Architecture Description
+++-==============-============-============-========================================
ii  evok           2.4.8        armhf        UniPi API based on the Tornado webserver

evok is not able to change board watchdog state.
Please, ¿is there some way (Evok or whatever) to set on board watchdog?

Thanks.

Hi @smontosa,
you are correct. There is indeed some problem with setting the watchdog via Evok. I reported this to our developers and make sure this will be fixed in 2.4.10.

As a workaround, you can set the watchdog via ModbusTCP. You can use mbpoll (not preinstalled, can be installed via apt update && apt install -y mbpoll):

# enable the MWD
mbpoll 127.0.0.1 -a 1 -0 -1 -r 6 1
# set timeout to 3333ms
mbpoll 127.0.0.1 -a 1 -0 -r 1008 3333
# write this settings to the NVRAM
mbpoll 127.0.0.1 -a 1 -0 -1 -t 0 -r 1003 1

Best regards,
Martin

Hello @smontosa,

please try to download the current version 2.4.10. The issue should be fixed. Please note that watchdog settings (same as other parameters) are stored in RAM memory by default. To burn it into non-volatile memory (FLASH), use the appropriate coil 1003 or call the separate REST request on the same endpoint with parameter nv_save=1.
