--write_update_flag是入口函数
void write_update_flag(uint32_t flag) {
      if(FMC_flash_write_word(0x80FC00, 0xaa))

      else
            printf("FMC_flash_write_word error\n");

      FMC_flash_read_word(0x80FC00);
}

uint8_t FMC_flash_write_word(uint32_t address, uint32_t pData)
{
      fmc_state_enum FLASHStatus;
      uint32_t AddressTemp = 0;

      AddressTemp = address ;

      printf("FMC_flash_write_word write: %d \r\n",pData);
      fmc_unlock();
      fmc_page_erase(AddressTemp);
      fmc_flag_clear(FMC_FLAG_END | FMC_FLAG_WPERR | FMC_FLAG_PGERR);

            return 0;
      }
      if (FLASHStatus != FMC_READY){
