    how did you set UBC? If you programmed optin bytes from your firmware (C or ASM code) then you need to apply a reset to make them effective. If you used STVP to set UBC, a reset is applied by the debugger automatically to make option bytes to be loaded. I suggest you to set all option bytes using STVP.
