Debugger doesn't start (HardFault / MemManage)

Hello, 

after facing problem with ULINK2 with using Memory layout from Target Register of uVision, I have switched to Scatterfile with followed content:

; *************************************************************
; *** Scatter-Loading Description File generated by uVision ***
; *************************************************************
LR_IROM1 0x08000000 0x00100000  {    ; load region size_region
  ER_IROM1 0x08000000 0x00100000  {  ; load address = execution address
   *.o (RESET, +First)
   *(InRoot$$Sections)
   .ANY (+RO)
   .ANY (+XO)
  }
  RW_SDRAM1 0xC0000000 0x00100000  {  ; RW data stored in SDRAM (1M)
   .ANY (+RW +ZI)
  }
  RW_IRAM1 0x20000000 0x00040000  {
   .ANY (+RW +ZI)
  }
  RW_IRAM2 0x20040000 UNINIT 0x00010000  {
    EventRecorder.o (+ZI)
  }
}

But now I can not start my Debugger, because I'm redirect to HardFault_Handler. If I stop the debugger and show Callee Code, it points to MemManage_Handler.

I'm trying to access in Compiler v5 (C99 mode) external SDRAM from CubeMX and self defined Viriable as followed:

__attribute__ ((at(0xC0050000))) uint32_t framebuffer[2];

Who knows the solution? Maybe the Scatter file is wrong for that situation?
