极海32F030芯片读写保护时，没找到xx32F0xx Flash_OPT.FLM文件

#define OB_BASE             ((uint32_t)0x1FFFF800)       /*!< FLASH Option Bytes base address */#define OB                ((OB_TypeDef *) OB_BASE)

FLASH_Status FLASH_OB_Erase(void)
{
  uint16_t rdptmp = OB_RDP_Level_0;

  FLASH_Status status = FLASH_COMPLETE;

  /* Get the actual read protection Option Byte value */
  if(FLASH_OB_GetRDP() != RESET)
  {
rdptmp = 0x00;
  }

  /* Wait for last operation to be completed */
  status = FLASH_WaitForLastOperation(FLASH_ER_PRG_TIMEOUT);

  if(status == FLASH_COMPLETE)
  {
/* If the previous operation is completed, proceed to erase the option bytes */
FLASH->CR |= FLASH_CR_OPTER;
FLASH->CR |= FLASH_CR_STRT;

/* Wait for last operation to be completed */
status = FLASH_WaitForLastOperation(FLASH_ER_PRG_TIMEOUT);

if(status == FLASH_COMPLETE)
{
   /* If the erase operation is completed, disable the OPTER Bit */
   FLASH->CR &= ~FLASH_CR_OPTER;

   /* Enable the Option Bytes Programming operation */
   FLASH->CR |= FLASH_CR_OPTPG;

   /* Restore the last read protection Option Byte value */
   OB->RDP = (uint16_t)rdptmp;

   /* Wait for last operation to be completed */
   status = FLASH_WaitForLastOperation(FLASH_ER_PRG_TIMEOUT);

   if(status != FLASH_TIMEOUT)
   {
      /* if the program operation is completed, disable the OPTPG Bit */
      FLASH->CR &= ~FLASH_CR_OPTPG;
   }
}
else
{
   if (status != FLASH_TIMEOUT)
   {
      /* Disable the OPTPG Bit */
      FLASH->CR &= ~FLASH_CR_OPTPG;
   }
}
  }
  /* Return the erase status */
  return status;
}

请问有用过极海的读保护的吗，这个OPT.FLM文件去哪找
