STM32F0 and Read Out Protect problem

I want to protect ST32F030 code RDP_Level_1. I use stadrard perihperial library and call protect function when program starts:


void ProtectMcu (void)


   if(FLASH_OB_GetRDP()==SET) return;



But it doesnt work. The function executes full sentence each time the processor starts. I also power down device but with no effect - code is not protected and can be read by a debugger.

When I protect device by a programmer it is protected ok.

Where is the problem ?


With best regards
