    Hi
    Can anyone help me with Linker LD script memory allocation
    I need to write a embedded bootloader

    The bootloader should be placed i ROM at 0xa000 and above . The code should
    include some function foo1()... foo10(). and main() and crt0

    The CPU starts at 0x0000 where it should be vector which should point to
    crt0 (rom version)
    .After boot process . The bootloader wil copy its Ram based program ( runing
    in RAM) from external device (Rs232) .

    The Memory is mapped as
    000-0x50 Hardware vectors (prom)
    0x52---0x1ffe Program RAM Where the sshould be copied from external
    device
    2000-3000 Ram ( ram , heap , stack)
    0xa000-0xc000 ROM (bootloader)

    How should I write a LD script file for both Rom and Ram based version

    With regards
    George Arndt
