Hello everyone!

I'm trying to store a user data in flash memory by the nexf source code #define FLASH_START_ADDR  ((uint32_t)0x08000000) #define FLASH_END_ADDR      ((uint32_t)0x0803FFFF) #define FLASH_PAGE_SIZE       ((uint16_t)0x800)     #define USER_DATA_START      FLASH_END_ADDR-  FLASH_PAGE_SIZE FLASH_EraseInitTypeDef EraseInit; uint64_t Data= 1; HAL_FLASH_Unlock();     EraseInit.NbPages= FLASH_BANK_1;     EraseInit.PageAddress= (uint32_t)USER_DATA_START;     EraseInit.TypeErase= FLASH_TYPEERASE_PAGES;     EraseInit.NbPages= 1;     HAL_FLASH_Unlock();     Rslt= HAL_FLASHEx_Erase(&EraseInit, &PageError);  HAL_FLASH_Program(FLASH_TYPEPROGRAM_HALFWORD,USER_DATA_START, Data); // tracing from this line     HAL_FLASH_Lock(); The program crushes inside FLAH_Program_HalfWord function at this line: SET_BIT(FLASH->CR, FLASH_CR_PG); // OK*(__IO uint16_t*)Address = Data;   // Crushes

The address you use can't be ODD. You should subtract whole pages from 0x08040000

Thanks for your reply clive1

The address for writting was odd really. Now it works
