Hi,

I am having a problem with the function FLASH_ProgramHalfPage it returns the error FLASH_ERROR_WRP but if I check the option bytes of my memory they are in Level 0 so it is not protected. Also I can connect my device to St-Link utility without changing the option bytes but if I run my code  can not write in the memory because of the error mentioned. 

I would like to know how this can happen if I haven't changed the option bytes of the memory.

Thanks in advance for your help.

I had a similar problem due to enabling/disabling Read Protection. Additionally, trying to undo it only results in continued issues with writing to Flash. It appears my Option Bytes are corrupt and I'm trying to find a way to restore them, hopefully ISP so I can do it through a firmware update and not have to connect a programmer.
