Part Number: MSPM0G3519
Hi,
My code is getting stuck in hardware in default handler function after jump to the application. I am not able to run the application alone in debug mode also. it always stuck in default handler with Ipsr =3 menas HardFault . Please help to resolve the issue
//My jump function code
typedef void (*AppFunc)(void);
#define APP_START_ADDR (0x00008000U)
void jumptoflash(void)
{
uint32_t appStack;
uint32_t appResetHandler;
AppFunc appEntry;
/* Disable global interrupts */
__disable_irq();
// /* Disable SysTick */
SysTick->CTRL = 0;
SysTick->LOAD = 0;
SysTick->VAL = 0;
/* Disable NVIC interrupts */
NVIC->ICER[0] = 0xFFFFFFFF;
NVIC->ICPR[0] = 0xFFFFFFFF;
/* Read application vector table */
appStack = *(volatile uint32_t *)APP_START_ADDR;
appResetHandler = *(volatile uint32_t *)(APP_START_ADDR + 4U);
/* Validate reset handler */
if(appResetHandler == 0xFFFFFFFFU)
{
return;
}
Also Find my Memory Map
/* Set vector table */
SCB->VTOR = APP_START_ADDR;
/* Set MSP from app vector table */
__set_MSP(appStack);
/* Jump to application reset handler */
appEntry = (AppFunc)appResetHandler;
appEntry();
while(1);
}
