MSPM0L1228: About DL_SYSCTL_enableSuperCapacitor

Part Number: MSPM0L1228

Tool/software:

Hi sir,

We have a capacitor on our board and we need to enable super capacitor charge. But it will crash after calling DL_SYSCTL_enableSuperCapacitor(). Is there any procedure need to do before enabling it?

Thanks,

Need to confirm what's this crash means.

Do you have detailed information or some error log?

Or CPU run into defaulthandler?

Hi Helic,

Yes, CPU run into Default_Handler().

void NMI_Handler(void) {
    __asm("NOP");
    __BKPT(0);
}

void HardFault_Handler(void) {
    __asm("NOP");
    __BKPT(0);
}

Add these in main.c file.

Pease refer to SYSCTL->NMIIIDX register and Table 2-15. Error Sources and Handling Mechanisms in TRM to find more error information.

This is from G series TRM, yours need to refer to L series TRM.

Hi Helic,

We got stuck at NMI_handler().

Hi Helic,

As I checked, if it's caused by VBAT_ON, it maybe normal case, right?

And how could I check if the interrupt was caused by which event?

Thanks,

Edware
