Read Protection: STM32F0-Series
Having trouble getting the Read Protection of the flash memory implemented.
I’m using a STM32F030K6, and STM32F030F4
Steps have been taken as follows:
FLASH_OB_Unlock(); //Unlocks the Operation Byte
FLASH_OB_RDPConfig(OB_RDP_Level_1); //Applies level 1 security
FLASH_OB_Launch(); //Reloads the OBL_LAUNCH bit in flash control register
FLASH_OB_Lock(); //Lock Operation Byte
In adition, a system power reset is implemented by taking power away from the chip and then re-applying, this should reload the new RDP option byte.
These are the steps the reference manual suggests, but i have met with no success. Level 1 security should PREVENT anything from reading the flash, thus protecting the code. However i am able to view the flash memory via the Debugger and uploading to ST-Link, proving it is not protected.
Any ideas would be much appreciated
