Hi guys,
I am using the STM32H750 and try to reprogram the internal 128KB flash.
Please check my code as below :
During the programming i got the "PGSERR" randomly , and error code is "0x00040000 "
Any comment , thanks
HAL_FLASH_Unlock();
__HAL_FLASH_CLEAR_FLAG_BANK1 (FLASH_FLAG_PGSERR_BANK1 | FLASH_FLAG_INCERR_BANK1); // clear error flag before do it
EraseInternalFlash(0x08000000); // Erase IAP area begin address and size
Write_Addr=0x08000000;
do
{
Read_Size = fs_fread(Temp_512Bytes,1,512,fp);
ProgramImage(Write_Addr,Temp_512Bytes);
Write_Addr=Write_Addr+512;
}while (Read_Size != 0);
void EraseInternalFlash (uint32_t BeginAddr)
{
uint32_t PAGEError = 0; uint8_t Retry=0;
FLASH_EraseInitTypeDef EraseInitStruct; u32 SECTORError;
/* Unlock the Flash to enable the flash control register access *************/
/* Fill EraseInit structure*/
EraseInitStruct.TypeErase = FLASH_TYPEERASE_SECTORS; // erase use sector type
EraseInitStruct.VoltageRange = FLASH_VOLTAGE_RANGE_3;
EraseInitStruct.Banks = FLASH_BANK_1;
EraseInitStruct.Sector = FLASH_SECTOR_0; // sector 0
EraseInitStruct.NbSectors = 1; // NbOfSectors; 1 sector for H750 is 128KB
if (HAL_FLASHEx_Erase(&EraseInitStruct, &SECTORError) != HAL_OK)
{
/*
Error occurred while sector erase.
User can add here some code to deal with this error.
SECTORError will contain the faulty sector and then to know the code error on this sector,
user can call function 'HAL_FLASH_GetError()'
*/
/* Infinite loop */
printf(" Erase flash error \r\n ");
while (1);
}
}
static bool ProgramImage(uint32_t Address, u8* Buffer)
{
u32 j=0; uint32_t Data;
Data = (uint32_t) Buffer;
for (j = 0; j < 512 ; j += 32)
{
if (HAL_FLASH_Program(FLASH_TYPEPROGRAM_FLASHWORD, Address, Data) == HAL_OK)
{
Address = Address + 32;
Data = Data + 32;
}
else
{
/* Error occurred while writing data in Flash memory.
User can add here some code to deal with this error */
printf(" ***** Program Error(%x)(%x) ***** \r\n ",Address,HAL_FLASH_GetError());
return false;
}
}
return true;
}
