Hi all,

Anyone knows why the following code is not disabling the flash memory readout protection? It is being executed on a STM32F103 microcontroller.

FLASH_Unlock();

FLASH_ReadOutProtection(DISABLE);

FLASH_UserOptionByteConfig(OB_IWDG_SW, OB_STOP_NoRST, OB_STDBY_NoRST);

FLASH_Lock();

__disable_irq();

NVIC_SystemReset();

Thanks

Hi pey.carles,

It seems that you miss the function that allow the access to option bytes sector:

FLASH_OB_Unlock();
