Which part of the FAQ didn't you understand?

What exactly do you mean? Ther eis no such thing as CFG_ENV.

It's you who designs the memory map of your system. Make sure to take
into account the reset vector address of your processor.

And you expect that we all know  what  FLASH_RESET,  FLASH_READY  and
C_MEMO_*  means  in  your  project?  I'm  sorry, but at the moment my
crystal ball is in dire need of an ectoplasmic upgrade.
