watchdog on AM335x?

Hi,

I'm now evaluating Cutsom AM335x board with our linux EZSDK 5.05.

I have 2 questions about watch.

1. enable watchdog

I just installed EZSDK5.05(and run setup.sh).  From booting log, I can find following message. Then can I assume that watchdog timer is enabled? Please confirm it.

[   19.630763] OMAP Watchdog Timer Rev 0x01: initial timeout 60 sec

2. Then how can I test if watchdog timer is working properly.. Is there any method that  I make 'kernel-panic'-like environment  manually?

Thanks and BR,

Devin
