Hardfault :STM32H750 Customer Bootloader Jump to Application
Hello everyone:
I have a problem with my project.
My project is to use STM32H750UBKx + Keil MDK5 IDE to design.
The customer bootloader runs in Flash, and The application runs in Quad SPI NOR Flash (or SRAM).
Problem: When I execute the code "JumpToApplication();", it will be "Hardfault"
Thanks!
more information:
0. I have checked that the data in the SRAM(0x30000000) is the same as the bin content compiled by my application.
1. The fault reporter(debug):
2.My Bootloader code are:
void RunApplication(void)
{
extern volatile uint8_t arrAppBuff[100 * 1024];
MemCpy((uint8_t *)arrAppBuff, (uint8_t *)0x90000000, 100*1024);
uint32_t nAppAddr = 0x30000000;
uint32_t JumpAddress = *(__IO uint32_t*)((nAppAddr) + 4);
pFunction JumpToApplication = (pFunction)JumpAddress;
printf("Jump!\n");
HAL_RCC_DeInit();
HAL_DeInit();
SysTick->CTRL = 0;
SysTick->LOAD = 0;
SysTick->VAL = 0;
SCB->VTOR = (nAppAddr);
__set_PRIMASK(1);
__set_MSP(*(__IO uint32_t*)(nAppAddr));
__set_CONTROL(0);
JumpToApplication();
}3. Application code:
int main(void)
{
__disable_irq();
SCB->VTOR = 0x30000000;
__enable_irq();
SCB_EnableICache();
SCB_EnableDCache();
HAL_Init();
SystemClock_Config();
PeriphCommonClock_Config();
}4. Application 's scatter file:
