I have problem memory-access in Redboot


 Hello.  I am developing MPC850-board.

 I made redboot without flash-device , ethernet-device. and I burned Redboot into MPC850-board.
 
Currently  I make new-Redboot enabling flash-device. This Redboot is downloaded into board through redboot.
 
 do_flash_init() ( in redboot/current/src/flash.c) is complete 
but at  "memcpy(config, cfg_base, sizeof(struct _config))" in  load_flash_config()(  in redboot/current/src/flash.c) 
error occurs.   using gdb , I know bus-error occurs in memcpy. 
 memory-region( which cannot be accessed )  is near the CYGMEM_SECTION_heap1. 
 what's problem? please help me~
