Posted on November 18, 2014 at 15:40Still the proble persisits,
I have enabled UART and print the message where the loop hang inside the code. My bootloader code strucks inside hard fault handler when execute
if (STM_EVAL_PBGetState(BUTTON_USER) == Bit_SET)
It only happenes in the release mode. Debugger mode works fine. What could be the problem ? Is there any good method to find the problem to print through UART.
Here is my Main Loop,
int main(void)
{
/* STM32 evalboard user initialization */
BSP_Init();
init_USART6(9600);
ALARM_LED_Config();
USART_puts(USART6, ''Init complete! Hello World!\r\n''); // just send a message to indicate that it works
/* Flash unlock */
FLASH_If_FlashUnlock();
/* Test if User button on the Discovery kit is pressed */
if (STM_EVAL_PBGetState(BUTTON_USER) == Bit_SET)
{
/* Check Vector Table: Test if user code is programmed starting from address
''APPLICATION_ADDRESS'' */
if (((*(__IO uint32_t*)APPLICATION_ADDRESS) & 0x2FFE0000 ) == 0x20000000)
{
FLASH_Lock();
USART_puts(USART6, ''Jumb to app\r\n'');
/* Jump to user application */
JumpAddress = *(__IO uint32_t*) (APPLICATION_ADDRESS + 4);
Jump_To_Application = (pFunction) JumpAddress;
/* Initialize user application's Stack Pointer */
__set_MSP(*(__IO uint32_t*) APPLICATION_ADDRESS);
Jump_To_Application();
}
}
USART_puts(USART6, ''Init USBH\r\n'');
/* Init Host Library */
USBH_Init(&USB_OTG_Core, USB_OTG_FS_CORE_ID, &USB_Host, &USBH_MSC_cb, &USR_Callbacks);
while (1)
{
/* Host Task handler */
USBH_Process(&USB_OTG_Core, &USB_Host);
}
}
Thanks in advance.
