Watch-Dog-Timer cause reboot
 

Could anyone gives me any information related to watch-dog-timer that causes my product to reboot???

Any information will be helpfuly!!
Zillioms and thousands of thank you!!

What product? And what do you want to know?
Specific hardware? Which CPU/microcontroller?

In general:
A watchdog-timer is a counter that counts to a certain value (sometimes a programmable value). When that value is reached, a reset signal is generated.
To prevent a reset, you have to 'kick' the watchdog-timer at a regular base. And here it depends on what kind of hardware you're talking about.
Microcontroller? Probably write to a register.
External watchdog? Probably toggle (or pulse) a pin on the wdt.

Hello All,

Please dun ignore my "reboot" problem!
The error message is WDT_OVERFLOW.
I am using sh7709s, microprocessor.
But I am not the one designing the product.
Is there any ways to check on the wdtd portion??
What are the files related to wdtd??

Greatly Appreciate anyone who helps!!

Sorry, not familiar with SH7709 and I don't seem to be able to easily find datasheets, application notes and programmer information.

So what are you doing? Programming it? Or using it?

When do you get that message? Compile time, while running in debugger, runtime ?
Sounds to me like a warning from a (hardware) debugger.

Debugger.

How do you mean? Documentation files? Source files? Ask the programmer who's writing the code.
