we want to migrate from stm32f4xx to stm32f7xx , so this program bootloader DFU on stm32f4xx , it's works , and no on stm32f7xx
void bootloader_DFU_400(void )
{
/* La fonction est compilée uniquement si on est sur un micro STM32F4xx */
typedef void (*pFunction)(void);
pFunction Jump_To_Application;
vu32 JumpAddress;
GPIO_InitTypeDef GPIO_InitStructure;
vu8 bouton_DFU;
/* Activation Clock GPIO_BP_DFU */
RCC_AHB1PeriphClockCmd( RCC_GPIO_BP_DFU, ENABLE );
/* Configuration de PE3 en entrée */
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL;
GPIO_InitStructure.GPIO_Pin = PIN_BP_DFU;
GPIO_Init( GPIO_BP_DFU, &GPIO_InitStructure );
/*
Lecture de l'état du bouton DFU
0 : Bouton DFU appuyé
1 : Bouton DFU relaché
*/
bouton_DFU = GPIO_ReadInputDataBit( GPIO_BP_DFU, PIN_BP_DFU );
/* Si le bouton est appuyé (bouton_DFU = 0) on lance le programme du DFU */
if ( bouton_DFU == 0x00 )
{
JumpAddress = *(vu32*) (ADRESSE_FLASH_DFU + 4);
Jump_To_Application = (pFunction) JumpAddress;
RCC->APB2ENR = 0x00004000; //ChL 15/04/2016 besoin de ces 2 lignes pour les micros serie F42x et supérieurs
SYSCFG->MEMRMP = 0x00000001; //ChL 15/04/2016 besoin de ces 2 lignes pour les micros serie F42x et supérieurs
/* Initialize user application's Stack Pointer */
__set_MSP(*(vu32*) ADRESSE_FLASH_DFU);
Jump_To_Application();
}
else
{
if (((*(vu32*)ApplicationAddress) & 0x2FFE0000 ) == 0x20000000)
{ /* Jump to user application */
/* Test if user code is programmed starting from address 0x8004000 */
/* Jump to user application */
JumpAddress = *(vu32*) (ApplicationAddress + 4);
Jump_To_Application = (pFunction) JumpAddress;
/* Initialize user application's Stack Pointer */
__set_MSP(*(vu32*) ApplicationAddress);
Jump_To_Application();
}
}
}
