I have a STM32F769I-Eval and want to use the DFU bootloader.
From the application I can start the bootloader with the code below. The devices is recognized in Windows as a DFU device and I can use DfuSe to upload code to the device. Perfect.
static void Jump_to_bootloader (void)
{
/* Reinitialize the Stack pointer and jump to application address */
JumpAddress = *(__IO uint32_t *) (0x1FF00000 + 4);
Jump_To_Application = (pFunction) JumpAddress;
/* Initialize user application's Stack Pointer */
__set_MSP(*(__IO uint32_t*) 0x1FF00000);
Jump_To_Application();
}
But I am not able to force the STM32F7 to go to the bootloader after power up. From the documentation it is my understanding that I must set SW1 to 1 and JP1 is open. Then the bootloader should start when the board is powered up. But the device is not recognized as as DFU device in Windows.
What am I doing wrong?
