eCos linking question


Hi,

I'm trying to update the linker scripts to have code running from an
external flash on a Atmel at91sam7se32.
I started with the linker script for the at91sam7s32 (doesn't have an
external bus), and I started change that LDI script.

My LDI file now looks like this:
#include <cyg/infra/cyg_type.inc>
#include <pkgconf/hal_arm_at91sam7.h>
#include CYGBLD_HAL_PLATFORM_H

MEMORY
{
    sram : ORIGIN = 0x00200000, LENGTH = 0x02000
ram : ORIGIN = 0x20000000, LENGTH = CYGHWR_AT91_SAM7SE_RAM_SIZE
	srom : ORIGIN = 0x00100000, LENGTH = 0x8000
    rom : ORIGIN = 0x10000000, LENGTH = CYGHWR_AT91_SAM7SE_FLASH_SIZE
}


SECTIONS
{
    SECTIONS_BEGIN
    SECTION_rom_vectors (rom, CYGNUM_HAL_ARM_AT91_IMAGE_ADDRESS, 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 (sram, 0x00200040, LMA_EQ_VMA)
    SECTION_data (ram, ALIGN (0x4), FOLLOWING (.gcc_except_table))
    SECTION_bss (ram, ALIGN (0x4), LMA_EQ_VMA)
    CYG_LABEL_DEFN(__heap1) = ALIGN (0x8);
    SECTIONS_END
}
