写保护：

    FLASH_OBProgramInitTypeDef obStruct;
    HAL_FLASHEx_OBGetConfig(&obStruct);

    obStruct.OptionType |= OPTIONBYTE_RDP | OPTIONBYTE_WRP;
    obStruct.RDPLevel = OB_RDP_LEVEL_1;
    HAL_FLASH_OB_Unlock();
    HAL_FLASHEx_OBProgram(&obStruct);
    HAL_FLASH_OB_Launch();

去保护：

    FLASH_OBProgramInitTypeDef obStruct;
    HAL_FLASHEx_OBGetConfig(&obStruct);
    obStruct.OptionType |= OPTIONBYTE_RDP | OPTIONBYTE_WRP;
    obStruct.RDPLevel = OB_RDP_LEVEL_0;
    HAL_FLASH_OB_Unlock();
    HAL_FLASHEx_OBProgram(&obStruct);
    HAL_FLASH_OB_Launch();
