I compiled a test case from the following website,
http://www.lpclinux.com/Blogs/Testing_LPC313x_Linux_Watchdog_Driver

It works well.

root at ti-omap3:/tmp# ./a.out -h
Usage: ./a.out [options]
-h --help Display this usage information.
-d --dev <device_file> Use <device_file> as watchdog device file.
The default device file is '/dev/watchdog'
-i --interval <interval> Change the watchdog interval time
root at ti-omap3:/tmp# ./a.out -i 40;
Set watchdog interval to 40
Current watchdog interval is 40
Last boot is caused by : Watchdog
Use:
<w> to kick through writing over device file
<i> to kick through IOCTL
<x> to exit the program
x
Goodbye !
watchdog: Omap Watchdog: nowayout prevents watchdog to be stopped!
watchdog: Omap Watchdog: watchdog did not stop!
root at ti-omap3:/tmp# for i in `seq 1 30`; do echo $i; sleep 1;done
1
2

I built NOWAYOUT in driver, so it doesn't stop, still going until the
following
information:

Texas Instruments X-Loader 1.42
