CC2540: About HAL_SYSTEM_RESET();

Do you set a breakpoint on it to see if it hits?

Yes, I set a breakpoint on it. and hits it.

How do you judge it doesn't reset?

This is my code:
static void peripheralStateNotificationCB( gaprole_States_t newState )
{
switch ( newState )
{
case GAPROLE_STARTED:
{
uint8 ownAddress[B_ADDR_LEN];
uint8 systemId[DEVINFO_SYSTEM_ID_LEN];

GAPRole_GetParameter(GAPROLE_BD_ADDR, ownAddress);

// use 6 bytes of device address for 8 bytes of system ID value
systemId[0] = ownAddress[0];
systemId[1] = ownAddress[1];
systemId[2] = ownAddress[2];

// set middle bytes to zero
systemId[4] = 0x00;
systemId[3] = 0x00;

// shift three bytes up
systemId[7] = ownAddress[5];
systemId[6] = ownAddress[4];
systemId[5] = ownAddress[3];

DevInfo_SetParameter(DEVINFO_SYSTEM_ID, DEVINFO_SYSTEM_ID_LEN, systemId);
}
break;

case GAPROLE_ADVERTISING:
HalLedSet(HAL_LED_1, HAL_LED_MODE_ON );
break;

case GAPROLE_CONNECTED:
HalLedSet(HAL_LED_1, HAL_LED_MODE_OFF );
break;

case GAPROLE_WAITING_AFTER_TIMEOUT:
// Link terminated intentionally: reset all sensors
SystemReset();
break;

default:
break;
}

gapProfileState = newState;
}

If system is reset, I use LightBlue app can find it.
but I can not find my cc2540.

Can you set a breakpoint in main function to see if it hits after you call reset macro?

Hello,

In your reset function, can you add a while (1) loop:

while(1)
HAL_SYSTEM_RESET();

Best wishes

No, after i call reset macro, main function breakpoint do not hit.

I add "while(1)" in my code, but system also can not reset.

Just test HAL_SYSTEM_RESET with Keyfob example in BLE Stack v1.4.2 and it resets as expected. Check if your HAL_SYSTEM_RESET is defined like the followings:

#define WD_EN BV(3)
#define WD_MODE BV(2)
#define WD_INT_1900_USEC (BV(0) | BV(1))
#define WD_RESET1 (0xA0 | WD_EN | WD_INT_1900_USEC)
#define WD_RESET2 (0x50 | WD_EN | WD_INT_1900_USEC)
#define WD_KICK() st( halIntState_t _s; HAL_ENTER_CRITICAL_SECTION(_s); WDCTL = (0xA0 | WDCTL & 0x0F); WDCTL = (0x50 | WDCTL & 0x0F); HAL_EXIT_CRITICAL_SECTION(_s);)

/* disable interrupts, set watchdog timer, wait for reset */
#define HAL_SYSTEM_RESET() st( HAL_DISABLE_INTERRUPTS(); WDCTL = WD_RESET1; WDCTL = WD_RESET2; for(;;); )

Thank you for your reply, I really appreciate your help in resolving the problem.
I have try this function.

This function can reset system.

static void hidappHandleKeys( uint8 keys, uint8 state )
{
// Unused arguments
(void) state;
if (keys & HAL_KEY_SW_1)
{
SystemReset();
}
if (keys & HAL_KEY_SW_2)
{

}
}


I don't know why in 'case GAPROLE_WAITING_AFTER_TIMEOUT' cannot be reseted.

How do you make GAPROLE_WAITING_AFTER_TIMEOUT case happens?

Hi guys, I confused and it works now, I am really sorry for causing any inconvenience.
