How to disable watchdog

In Feature phone's production release version, (1) the system fails to capture memory dump or (2) watchdog timeout when the JTAG is used to analyze the problem. You can disable watchdog to debug the problem, the method for disabling is as follows:

 

The method of disabling watchdog in 11A before is to change the parameter in the WDT_Enable () function to kal_FALSE. As follows:

Application_Initialize () (init \ src \ init. c) like this:

# Ifdef _ PRODUCTION_RELEASE __

# Ifdef _ MULTI_BOOT __

If (system_boot_mode! = FACTORY_BOOT)

# Endif/* _ MULTI_BOOT __*/

// WDT_Enable (KAL_TRUE );

WDT_Enable (KAL_FALSE );

# Endif/* _ PRODUCTION_RELEASE __*/

 

The method of disabling watchdog after (including 11A) is to change wdt_data.fgEnable = kal_TRUE to KAL_FALSE. As follows:

Application_Initialize () (hal \ system \ init \ src \ init. c) like this:

# Ifdef _ PRODUCTION_RELEASE __

# Ifdef _ MULTI_BOOT __

If (system_boot_mode! = FACTORY_BOOT)

# Endif/* _ MULTI_BOOT __*/

// Wdt_data.fgEnable = KAL_TRUE;

Wdt_data.fgEnable = KAL_FALSE;

Init_dcl_wdt_handle = DclWDT_Open (DCL_WDT, 0 );

DclWDT_Control (init_dcl_wdt_handle, wdt_assist_enable, (DCL_CTRL_DATA_T *) & wdt_data );

DclWDT_Close (init_dcl_wdt_handle );

# Endif/* _ PRODUCTION_RELEASE __*/

 

If the content described above does not exist in Application_Initialize () (hal \ system \ init \ src \ init. c), but the WDT_SetValue (255) function exists,

The method to disable watch dog is: WDT_SetValue (255); replace it with WDT_Enable (KAL_FALSE );

 

Two feature options, FORCE_MEMORY_DUMP & FORCE_WATCHDOG_MUTE, are added to w12.36 11B to accelerate opening or disabling watch dog and memory dump. Modify the feature option in project make file and then remake system.
