I need a help with BDI2000(MPC8266) --which i think almost everyone here use--, can BDI2000 treat with a virgin board? a not erased Flash?
Yes, it can, of course.

assume a flash all programmed with zero , so all the first 256 bytes of flash are zero , and if cpu reads these configuration bytes it will be set incorrectly, is such flash programable by BDI2000?
Yes,of course.
(We developed a custom board. My flash should get FF for all bytes if erased. , I have a BDIPro and when I dump the flash, it's all zero ,it could not be erased nor programmed. what could I do, and what's my problem?)
If you are sure that you initialized the memory controller correctly it sounds like a hardware problem to me. Re-checking your initialization is probably a good idea, though.
