    Smile Bootloader + Mainline code in single HEX file

    I have developed a bootloader (in ASM). (relocatable)
    My mainline code is developed in PBP. (absolute)

    How can I create a single HEX file to program my pics?
    I don't think I can use a linker script since PBP apparently creates absolute code.

    Any suggestions?

    Anyone??

    Default Bootloader plus PBP code

    It should be possible to read the entire chip (i.e. the low address PBP code and the high address bootloader) as one fiile in a programmer such as EPIC. That file can then be used to program any new chips.

    That should streamline production but still leave open a serial bootloader for field mods.

    Hi,

    A bootloader is not much good if code protection is enabled.
    So, chances are, this shouldn't be a problem.
    I've tried Brian's method with success.

    Cheers!

    Sure it is.
    Why do you say that a bootloader is not good with CP on?

    Hi,

    My understanding is that if you set the code "protect" bit then the bootloader will not be able to write to program memory.
    Seems logical to me but I could be wrong.
