Build Error for new Hardware


Hi,

   I am getting the following error when I am building ecos for a custom
hardware board with SH7750 on it. What could be possibly wrong


make[1]: Leaving directory
`/ecos-c/MDP/ecos/sh7750/mdp7750_build/hal/common/current'
/ecos-c/MDP/ecos/sh7750/mdp7750_install/lib/libtarget.a(redboot_main.o): In

This is what my ..rom.ldi file look like

MEMORY

{

    ram : ORIGIN = 0x8c000000, LENGTH = 0x04000000

    rom : ORIGIN = 0x80000000, LENGTH = 0x01000000

}



SECTIONS

{

    SECTIONS_BEGIN

    SECTION_vectors (rom, 0x80000000, LMA_EQ_VMA)

    SECTION_text (rom, ALIGN (0x4), LMA_EQ_VMA)

    SECTION_fini (rom, ALIGN (0x4), LMA_EQ_VMA)

    SECTION_rodata1 (rom, ALIGN (0x8), LMA_EQ_VMA)

    SECTION_rodata (rom, ALIGN (0x8), LMA_EQ_VMA)

    SECTION_fixup (rom, ALIGN (0x4), LMA_EQ_VMA)

    SECTION_gcc_except_table (rom, ALIGN (0x1), LMA_EQ_VMA)

    SECTION_data (ram, 0x8c000000, FOLLOWING (.gcc_except_table))

    SECTION_bss (ram, ALIGN (0x10), LMA_EQ_VMA)

    CYG_LABEL_DEFN(__heap1) = ALIGN (0x8);

    SECTIONS_END

}

I observed that the address pointed by error is no where in the region of
ram or rom.Any help would be great.

Thanks,
Raghu
