STM32F407G-disc1 - FatFs_USBDisk FatFs with USB disk drive application - Resets - Fails to Run

BAW · ‎2023-09-15

Hello,

I have a STM32F407G-disc1 and am trying to run the FatFs_USBDisk application. If I select debug, the program loads into the board and I can step through the application. If I resume running or instead of selecting debug, select run the program terminates and ends up in the Reset_Handler as shown below.

Any thoughts on why this is happening?

Do I have a jumper not properly set?

/* stack used for SystemInit_ExtMemCtl; always internal RAM used */

/**
 * @brief  This is the code that gets called when the processor first
 *          starts execution following a reset event. Only the absolutely
 *          necessary set is performed, after which the application
 *          supplied main() routine is called. 
 * @PAram  None
 * @retval : None
*/

    .section  .text.Reset_Handler
  .weak  Reset_Handler
  .type  Reset_Handler, %function
Reset_Handler:  
  ldr   sp, =_estack     /* set stack pointer */

Any help would be appreciated.

Thanks,

Brent
