Hi,

I'm porting eCos to a custom board with the Atmel AT91 processor
(ARM7TDMI-core, 8kB on-chip SRAM), using the edb7xxx as template.
After processor-reset the processor has the following memory map:

0x00000000 - 0x000FFFFF  external device such as boot-PROM/Flash
0x00300000 - 0x0031FFFF  8kB on-chip SRAM
0xFFC00000 - 0xFFFFFFFF  on-chip peripherals I/O
other address-space is reserved

So I wrote the following ldi-file:
MEMORY
{
    rom : ORIGIN = 0, LENGTH = 0x80000
    reserved : ORIGIN = 0x100000, LENGTH = 0x200000
    onchip_ram : ORIGIN = 0x300000, LENGTH = 0x2000
    reserved2 : ORIGIN = 0x302000, LENGTH = 0xff8fe000
    peripheral : ORIGIN = 0xffc00000, LENGTH = 0x3fffff
}

SECTIONS
{
    SECTIONS_BEGIN
    SECTION_rom_vectors    (rom, 0,           LMA_EQ_VMA)
    SECTION_rodata         (rom, ALIGN (0x4), LMA_EQ_VMA)
    SECTION_text           (rom, ALIGN (0x4), LMA_EQ_VMA)
    SECTION_data           (rom, ALIGN (0x4), LMA_EQ_VMA)
    SECTION_bss            (onchip_ram, 0x300000, LMA_EQ_VMA)
    SECTIONS_END
}

When I'm compiling the GDB-Stub, the linkers says
"/tools/H-i686-pc-linux-gnu/arm-elf/bin/ld: address 0x302dbc of
/boeller/home/andreas/develop/eCos/AT91/install/bin/gdb_module.img
section .bss is not within region onchip_ram"

Who eats up the on-chip ram space? The stub isn't much more than a
skeleton.

Thanks in advance.
