Hello,
I select the "BOR" Level 2 with these lines after init:

 FLASH->OPTKEYR = 0x08192A3B;
 FLASH->OPTKEYR = 0x4C5D6E7F;
 while(FLASH->SR & FLASH_SR_BSY);
  FLASH->OPTCR = 0x0FFFAAE4;
  FLASH->OPTCR = 0x0FFFAAE6;
 while(FLASH->SR & FLASH_SR_BSY);
  FLASH->OPTCR = 0x0FFFAAE7;

and after three power up, my STM32F407VG is totally blocked:
- Don't RUN
- No access with ULINK2 "Flash TimeOut. Reset the Target and try again"
Ok, I don't understand the link, but this problem happens since I added these lines. 
thank you for your help
