Hello All,

I want to reset my launchpad after certain event via software. How can I do this? Is it possible to use Watchdog timer?

How can i use this statement?

SysCtrlResetSourceGet( void );

Regards

    Hi,

    You can use the Watchdog time to reset your device. You just need to make sure that you don't reset the watchdog after you receive the event.

    You can look at this thread for some help with the Watchdog.

    SysCtrlResetSourceGet( void );

    Here are the possible return values of this function:

    #define RSTSRC_PWR_ON               (( AON_SYSCTL_RESETCTL_RESET_SRC_PWR_ON    ) >> ( AON_SYSCTL_RESETCTL_RESET_SRC_S ))
#define RSTSRC_PIN_RESET            (( AON_SYSCTL_RESETCTL_RESET_SRC_PIN_RESET ) >> ( AON_SYSCTL_RESETCTL_RESET_SRC_S ))
#define RSTSRC_VDDS_LOSS            (( AON_SYSCTL_RESETCTL_RESET_SRC_VDDS_LOSS ) >> ( AON_SYSCTL_RESETCTL_RESET_SRC_S ))
#define RSTSRC_VDD_LOSS             (( AON_SYSCTL_RESETCTL_RESET_SRC_VDD_LOSS  ) >> ( AON_SYSCTL_RESETCTL_RESET_SRC_S ))
#define RSTSRC_VDDR_LOSS            (( AON_SYSCTL_RESETCTL_RESET_SRC_VDDR_LOSS ) >> ( AON_SYSCTL_RESETCTL_RESET_SRC_S ))
#define RSTSRC_CLK_LOSS             (( AON_SYSCTL_RESETCTL_RESET_SRC_CLK_LOSS  ) >> ( AON_SYSCTL_RESETCTL_RESET_SRC_S ))
#define RSTSRC_SYSRESET             (( AON_SYSCTL_RESETCTL_RESET_SRC_SYSRESET  ) >> ( AON_SYSCTL_RESETCTL_RESET_SRC_S ))
#define RSTSRC_WARMRESET            (( AON_SYSCTL_RESETCTL_RESET_SRC_WARMRESET ) >> ( AON_SYSCTL_RESETCTL_RESET_SRC_S ))
#define RSTSRC_WAKEUP_FROM_SHUTDOWN ((( AON_SYSCTL_RESETCTL_RESET_SRC_M        ) >> ( AON_SYSCTL_RESETCTL_RESET_SRC_S )) + 1 )

    Regards,

    Thanks for the help Sir. I have taken help from the thread that you have mentioned but the device is not restarting. How can i use watchdog. One more thing, we cannot use Watchdog_clear(hWDT); in callback function but here we are using this. Take a look at this thread and then tell me how can i use watchdog.

    e2e.ti.com/.../2154936

    According to this thread we cant use Watchdog_clear() in callback function. What should i do in this case?

    Thanks and regards,
    Shubham

    Hi Shubham,

    Have you read the Doxygen documentation for the watchdog? (The link that Emmanuel gave you)

    Here is a copy-paste of what you are supposed to do with the callback function:

    In this function, the user may do whatever is appropriate for the application. Here are some suggestions:

    • do nothing so that the timer will timeout again and trigger the reset,
    • immediately reset the device,
    • do self-test to check the integrity of the application,
    • post a SWI or Task to do the self-test.

    So you choose what you want to do. If you do not know what do, don't put any code in the watchdog callback function (leave it empty) and let your microcontroller restart automatically.

    Regards,

    Michel
