Did you verify the time out changed? If so how?

Update: The kernel watchdog driver support tuning the timout through ioctl
calls. A quick and dirty bit of C code:
int main(){ int fd = open("/dev/watchdog", O_WRONLY); int timeout = 5;
ioctl(fd, WDIOC_SETTIMEOUT, &timeout); printf("Setting timeout to %d
seconds\n", timeout); close(fd); return 0;}
Will tune the watchdog. I use node.js' child_process to call the above code
(when compiled, obviously), if my node.js app crashes then the BBB will reboot.
Perfect

Where does one go to tune the watchdog timer? Is it a
kernel-recompilation-required thing, or can it be done through uBoot?
Or.... should I just use my PRU code to tune the watchdog control register when
it boots? This would be the easiest option for me, if someone can point me at
the correct area if the AM335XTRM? I had a look in there and couldn't find the
correct registers.
I'd like it to run about 10 seconds if possible for my application.
