Hi All, trying to write data into flash with dynamical flash address selection approach but it fails but at same time if hash(#) define the address the flash programming all works fine, Please suggest me the best solution and explain me the issues choosing dynamical address for flash address.
/*********************************************************************/
Note: 1. this code where I'm trying to flash using dynamic address approach.
2. and yes the logic to choose the address working fine I can read the value in target address variable.
typedef struct {
uint32_t active_app; // 1 for App1, 2 for App2
uint32_t app1_valid; // 1 if App1 is valid
uint32_t app2_valid; // 1 if App2 is valid
} BootInfo;
#define BOOT_INFO_ADDRESS 0x0802F000
int8_t UpdateFWBlueNRG(uint32_t *SizeOfUpdate,uint8_t * att_data, int32_t data_length)
{
int8_t ReturnValue=0;
/* Save the Packed received */
if(data_length>(*SizeOfUpdate)){
/* Too many bytes...Something wrong... necessity to send it again... */
// OTA_PRINTF("OTA something wrong data_length=%ld RemSizeOfUpdate=%ld....\r\nPlease Try again\r\n", (long)data_length, (long)(*SizeOfUpdate));
ReturnValue = -1;
/* Reset for Restarting again */
*SizeOfUpdate=0;
} else {
uint64_t ValueToWrite;
int32_t Counter;
// Clear all flash error flags
__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_PGAERR);
__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_WRPERR );
__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_FWWERR);
__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_NOTZEROERR);
BootInfo* boot_info = (BootInfo*)BOOT_INFO_ADDRESS;
uint32_t target_address = (boot_info->active_app == 1) ? 0x0801C000 : 0x08005000;
/* Save the received OTA packed ad save it to flash */
/* Unlock the Flash to enable the flash control register access *************/
HAL_FLASH_Unlock();
HAL_FLASH_OB_Unlock();
for(Counter=0;Counter<data_length;Counter+=8){
memcpy((uint8_t*) &ValueToWrite,att_data+Counter,8);
if(HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLE, target_address,ValueToWrite)==HAL_OK){
target_address+=8;
} else {
/* Error occurred while writing data in Flash memory.
User can add here some code to deal with this error
FLASH_ErrorTypeDef errorcode = HAL_FLASH_GetError(); */
while(1){

Now this code works fine if instead of choosing address dynamically and putting # define Writing_address 0x0801C000
#define Writting_addresss 0x0801C000
