Dear Gary Thomas,

I have modified the files as given below..

romram.h

#include <cyg/infra/cyg_type.h>
#include <stddef.h>

extern unsigned long SDRAMSize;
#define CYGMEM_REGION_ram (0)
#define CYGMEM_REGION_ram_SIZE (SDRAMSize)
#define CYGMEM_REGION_ram_ATTR (CYGMEM_REGION_ATTR_R | CYGMEM_REGION_ATTR_W)
#define CYGMEM_REGION_rom (0x60000000)
#define CYGMEM_REGION_rom_SIZE (0x1000000)
#define CYGMEM_REGION_rom_ATTR (CYGMEM_REGION_ATTR_R)
extern char CYG_LABEL_NAME (_heap1) [];
#define CYGMEM_SECTION_heap1 (CYG_LABEL_NAME (_heap1))
#define CYGMEM_SECTION_heap1_SIZE (CYGMEM_REGION_ram_SIZE - (size_t)
CYG_LABEL_NAME (_heap1))



romram.ldi

MEMORY

   ram : ORIGIN = 0, LENGTH = 0x10000000
   rom : ORIGIN = 0x60000000, LENGTH = 0x1000000
}

SECTIONS

   SECTIONS_BEGIN
   SECTION_fixed_vectors (ram, 0x20, LMA_EQ_VMA)
   SECTION_rom_vectors (ram, 0x8000, AT (0x60000000))
   SECTION_text (ram, ALIGN (0x4), FOLLOWING (.rom_vectors))

   _heap1 = ALIGN (0x8);

}

But still the redboot is not booting.
Please help.

Thanks & Regards,
