I think you have used the wrong startup type.

The ROM startup uses:

SECTIONS
{
SECTIONS_BEGIN
CYG_LABEL_DEFN(__reserved_bootmon) = 0x1800000; . = CYG_LABEL_DEFN(__reserved_bootmon) + 0x
20000;
SECTION_rom_vectors (rom, ALIGN (0x8), LMA_EQ_VMA)
SECTION_text (rom, ALIGN (0x1), LMA_EQ_VMA)
SECTION_fini (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata1 (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fixup (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_gcc_except_table (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fixed_vectors (ram, 0x20, LMA_EQ_VMA)
SECTION_data (ram, 0x8000, FOLLOWING (.gcc_except_table))
SECTION_bss (ram, ALIGN (0x4), LMA_EQ_VMA)
CYG_LABEL_DEFN(__heap1) = ALIGN (0x8);
SECTIONS_END
}

You see that the data section goes at address 0x8000. Im assuming you
have a ROM redboot. So its data section is at the same address you are
downloading your application.

The RAM startup code uses this layout:

SECTIONS
{
SECTIONS_BEGIN
SECTION_fixed_vectors (ram, 0x20, LMA_EQ_VMA)
SECTION_rom_vectors (ram, 0x10000, LMA_EQ_VMA)
SECTION_text (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fini (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata1 (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fixup (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_gcc_except_table (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_data (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_bss (ram, ALIGN (0x4), LMA_EQ_VMA)
CYG_LABEL_DEFN(__heap1) = ALIGN (0x8);
SECTIONS_END
}

Notice that rom_vectors section goes at 0x10000, and everythig else
follows that.

Make sure your build is a RAM build. You may need to delete your work
tree and start again.
