Hi,
I am working with BF533 custom board, uClinux dist 2007 R1-RC3, u-boot 1.1.6 2007 R1.
when i do a system("reboot") i am able to successfully boot the system.
When i do a watchdog timer reset sometimes my board is not booting.
I am unable to figure out what is done in the "reboot" utility command so that the system start booting succesfully.
Can any one you please guide me where i am doing wrong with the watchdog reset. Is i am missing something to do before i do a watchdog reset?
Best Regards,Sreedhar.

How do you generate the watchdog reset?

Hi,
I wrote a simple kernel function for watach dog timer reset. I called this function with a ioctl call.
Best Regards, Sreedhar.

If you'd like help debugging it, please post the code. Also post whatever output you get when the reboot fails.
