LPC54628 - putting global variables in BOARD_SDRAM

Hi!

 

I'm trying to figure out how external BOARD_SDRAM works. I have seen the sdram example from SDK but probably it does not show how to solve my problem. In MCUXpresso settings I can choose destination where all global variables will be put. I choose BOARD_SDRAM and everything compile fine. No warnings and BOARD_SDRAM has some usage. When I try to run or debug the program it stucks (In debug mode the breakpoint in first instruction is not set anymore). I modified the sdram example. EMC is configured through BOARD_InitSDRAM(). What have I do? Or maybe it's not as trivial as i think? Thanks for replies!
