You have a big hole between the bss LMA and the rom_vectors LMA. You could
try something like:

SECTIONS
{
    SECTIONS_BEGIN
    SECTION_rom_vectors    (rom, 0x01400000, LMA_EQ_VMA) 
    SECTION_rodata         (rom, ALIGN (0x4), LMA_EQ_VMA)
    SECTION_text           (rom, ALIGN (0x4), LMA_EQ_VMA) 
    SECTION_data           (dram, 0x00400000, FOLLOWING(.text))
    SECTION_bss            (dram, ALIGN (0x4), LMA_EQ_VMA)
    SECTIONS_END
}

Note that the bss section should always end the data segment since it
sometimes expand at runtime (maybe not in eCos but that's what the
brk() system call does in a UNIX-like OS).

Hope this works,

Robin
