Does not jump to the watchdog interrupt. (MKE04Z128)

[jun1]

Hello

The watchdog takes some reason, so I'm trying to skip to the watchdog interrupt (WDOG_DriverIRQHandler) and investigate where it's coming from.
The following sources.
I am using SDK_2.6.0_MKE04Z128xxx4.
What's wrong?

*** startup routine ***
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;
;;
;; Default interrupt handlers.

THUMB

PUBWEAK Reset_Handler
SECTION .text: CODE: REORDER: NOROOT (2)
Reset_Handler

＊＊＊＊＊Omit here

PUBWEAK WDOG_IRQHandler
PUBWEAK WDOG_DriverIRQHandler
SECTION .text: CODE: REORDER: NOROOT (2)
WDOG_IRQHandler
　　　LDR R0, = WDOG_DriverIRQHandler
　　　BX R0

.

＊＊＊＊＊Omit here

END

*** watchdog initialize ***
void boardWdogInit (void)
{
　　wdog8_config_t wdogConfig;
.
　　WDOG8_GetDefaultConfig (& wdogConfig);
　　wdogConfig.timeoutValue = WDOG_TIMEOUT;
　　wdogConfig.enableInterrupt = true;
.
　　WDOG8_Init (WDOG, & wdogConfig);
.
　　WDOG8_EnableInterrupts (WDOG, WDOG_CS1_INT_MASK);
　　NVIC_EnableIRQ (WDOG_IRQn);
}

*** interrupt routine ***
void WDOG_DriverIRQHandler (void)

}

Thank you.

Thank you very much.

Hi,

If your configuration is OK,you can set a val in handle to debug to watch if it is changed. But you need to avoid ram been inited after system reset.

" How should I use the assembler?"

step1: MCUXpresso IDE-> Debug the project you wants to check in assembler-> window->perspective-> assumbler

step2:

make brake point in startup before main function call

step3:

Press "F5" for line by line execution of assmbly at same time user memory attribution map for memory update

Hi.

thank you for your answer.

Is there an example of an assembler source that gets the stack data in a watchdog timer interrupt handler? I want to know where I jumped to the watchdog timer interrupt.

Hi.

https://community.nxp.com/message/939533 

When I saw this answer, it was stored in RAM, so it seems that it is jumping to an interrupt. (It looks like the debugger is catching up).

So another question is, I want to record the stack to know where it came from. How should I use the assembler? Please let me know if you have a sample.

thank you.
