The attached example code that illustrates how to configure the interrupt coming from Watchdog as “FAULT” in the SEC and that resets the processor. This code can be directly run on the ADSP-BF706 EZ-Kit MINI.
In order to demonstrate this scenario, the LED0 in the EZ-kit MINI is turned ON in the application code and watchdog timer configured to issue a reset via the SEC Fault Interface (SFI). Watchdog count never reloaded and hence it expires according to the count value given and that issues system reset upon expiry through Fault Management Unit (FMU). When you boot this application you would see that LED0 turns ON for a while and it goes off because of watchdog expiration that reset the processor. After processor reset it boots again and this loop continues.WDG_HWReset_706.zip
