Using WDIOS_DISABLECARD in ME 9210 Linux does not disable watchdog, why?

0 votes
I tried the sample application wd_test.c (as suggested in the docs for DigiESP 5.2 Linux) to test the watchdog with my ME 9210.

Everything seems to work, except for disabling the watchdog. The ioctl WDIOC_SETOPTIONS with WDIOS_DISABLECARD bit set simply does not have any effect, the watchdog keeps running and resets the system.

This would be correct behaviour only if CONFIG_WATCHDOG_NOWAYOUT was set to Y in the kernel config. However, this is *not* the case, so it should definitely be possible to disable the watchdog.

Any idea what could be wrong?

I would like to let you know that you have an old version of Digi Embedded Linux.

Did you buy this kit recently? If so you are entitled to get a free upgrade to DEL 5.7. Please contact Digi Technical Support.
