Posted on June 25, 2018 at 08:31OK thank you, this seems like a huge effort...
Anyway, trying to get the bootloader started from the application, with a code I found online. I changed the system memory address, according to the datasheet, however after executing the code, I always get a hard fault error. Anyone knows why?
CODE:
void (*SysMemBootJump)(void);
volatile uint32_t addr = 0x1FFF0000;
if(BootLoaderStatus == 1)
{
//Shutdown any tasks running
HAL_UART_DeInit(&huart1);
HAL_UART_DeInit(&huart2);
HAL_GPIO_DeInit(GPIOA,GPIO_PIN_6);
HAL_GPIO_DeInit(GPIOD,GPIO_PIN_5);
HAL_GPIO_DeInit(GPIOD,GPIO_PIN_4);
HAL_RCC_DeInit();
//Reset the systick timer
SysTick->CTRL = 0;
SysTick->LOAD = 0;
SysTick->VAL = 0;
//Disable Interrupts
__disable_irq();
//Remap system memory
__HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH();
HAL_DeInit();
//suspend all tasks from freeRTOS
vTaskSuspendAll();
//Set jump memory location for system memory (bootloader)
//Addres + 4 bytes offset which specifies jump location where programm starts
SysMemBootJump = (void(*)(void)) (*((uint32_t *)(addr + 4)));
//Set the main stack pointer to its default value
__set_MSP(*(uint32_t *)addr);
//Call the function to jump to the set location
//This will start system memory execution
SysMemBootJump();
while(1);
}
thank you
