The article is very vague on the specifics of the TK1.
You need to either:
(a) If the TK1 supports “magic”, then write the special “V” character to the device before closing, to ensure that the watchdog does not reset the system.
or
(b) If your system is setup with “nowayout”, then set tegra_wdt.nowayout=0 on the boot command line.
Your explication is correct. The behaviour of watchdog in linux is well described in the api documentation link text. Usually the toradex images are compiled with the Kernel option “WATCHDOG_NOWAYOUT”.
Thanks, how can I modify the boot command line?
I assume this would be done in uboot?
Which of the config params would I modify? (assuming booting from mmc),
