Hi, sir.
Before I speak, I'm Korean so English may be wrong.
But please help me... (T^T)
I am using STM32H743VIT for project. And I want to save Flash memoty to some data.
Sometime, It is return HAL_OK. So i can save some data in flash memory.
but Most of them fail to save...
The error code was return.
Error code is INCERR2: Bank 2 inconsistency error flag and PGSERR2: Bank 2 programming sequence error flag
what is woring?
I will attach my code and configuration.
1) my data size : 112000B
- uint32_t save_data[28000]
- It is in 0x24000000(AXI SRAM)
2) My compiler is IAR (8.34)
3) My Cubemx Setting
- Flash Latency(Ws) : 7 WS(8 CPU cycle)
4) My code is
void test_agetn_lan1_setting_save_flash(void) // bank2 - sector 1번
{
EnableWriteProtect(OPTIONBYTE_WRP,FLASH_BANK_2,FLASH_SECTOR_1,OB_WRPSTATE_DISABLE);
EraseFlash(FLASH_TYPEERASE_SECTORS,FLASH_SECTOR_1,FLASH_BANK_2);
HAL_Delay(10);
Flash_Wite_Func(LAN1_CSV_1_TO_100_SAVE_ADRSS,_32bit_lan1_csv_arr,_32BIT_LAN1_CSV_ARR_INDEX);
}void Flash_Wite_Func(uint32_t sector,uint32_t* data, uint16_t len)
{
HAL_FLASH_Unlock();
if(FLASH_Program(FLASH_TYPEPROGRAM_FLASHWORD, sector,data, len) != HAL_OK)
{
while(1);
}
HAL_FLASH_Lock();
}HAL_StatusTypeDef FLASH_Program(uint32_t TypeProgram, uint32_t FlashAddress, uint32_t *DataAddress, uint16_t len)
{
HAL_StatusTypeDef status;
__IO uint32_t *dest_addr = (__IO uint32_t *)FlashAddress;
__IO uint32_t *src_addr = (__IO uint32_t*)DataAddress;
uint32_t bank;
//uint8_t row_index = FLASH_NB_32BITWORD_IN_FLASHWORD;
uint16_t row_index = len;
/* Check the parameters */
assert_param(IS_FLASH_TYPEPROGRAM(TypeProgram));
assert_param(IS_FLASH_PROGRAM_ADDRESS(FlashAddress));
/* Process Locked */
__HAL_LOCK(&pFlash);
if(IS_FLASH_PROGRAM_ADDRESS_BANK1(FlashAddress))
{
bank = FLASH_BANK_1;
}
else
{
bank = FLASH_BANK_2;
}
/* Reset error code */
pFlash.ErrorCode = HAL_FLASH_ERROR_NONE;
/* Wait for last operation to be completed */
status = FLASH_WaitForLastOperation((uint32_t)50000U, bank);
if(status == HAL_OK)
{
if(bank == FLASH_BANK_1)
{
/* Set PG bit */
SET_BIT(FLASH->CR1, FLASH_CR_PG);
}
else
{
/* Set PG bit */
SET_BIT(FLASH->CR2, FLASH_CR_PG);
}
__ISB();
__DSB();
/* Program the 256 bits flash word */
do
{
*dest_addr = *src_addr;
dest_addr++;
src_addr++;
row_index--;
//HAL_Delay(1);
} while (row_index != 0U);
__ISB();
__DSB();
/* Wait for last operation to be completed */
status = FLASH_WaitForLastOperation((uint32_t)50000U, bank);
if(bank == FLASH_BANK_1)
{
/* If the program operation is completed, disable the PG */
CLEAR_BIT(FLASH->CR1, FLASH_CR_PG);
}
else
{
/* If the program operation is completed, disable the PG */
CLEAR_BIT(FLASH->CR2, FLASH_CR_PG);
}
}
/* Process Unlocked */
__HAL_UNLOCK(&pFlash);
return status;
}5) Error Code
- 0x8024000
plaese help me..
Thank you sir
