FLASH DATA WRITE PROBLEM IN STM32H743IIK6

[RShar.9]

Hello

i want to write some variable data on internal flash using HAL library but it not writing.

I am using blow code to write data to flash.

can you please tell what am i doing wrong.

#define FLASH_ADDRS   0x081E002A

#define FLASH_DATA_W 0x093

void FLASH_WRITE_DATA()

{

HAL_FLASH_Unlock();

FLASH_Erase_Sector(FLASH_SECTOR_7, FLASH_BANK_2, FLASH_VOLTAGE_RANGE_3);

HAL_FLASH_Program(FLASH_TYPEPROGRAM_FLASHWORD,FLASH_ADDRS,FLASH_DATA_W);

HAL_FLASH_Lock();

}

Instrument the code, report status/errors

Write to a WORD aligned address.

For the H7 write have to be 32 byte aligned and you write in chunks of 32 bytes, from my code:

int64_t initoptions[4] __attribute__ ((aligned (32)))
int64_t* volatile test;
test=(int64_t* volatile)initoptions;
HAL_FLASH_Program(FLASH_TYPEPROGRAM_FLASHWORD, (uint32_t)test, (uint64_t)((uint32_t)i64))

i will try it
