    Default simplest usb bootloader pbc solution ??

    Ok I'm back on the usb quest again...

    I've not played for about a year again, so no doubt now remember even less, and google is not (today) my friend....

    As I see it if I do find a simple 'ready to go' bootloader for noobs, {/link fairy please insert magical link here} I need to tell pbc to start assembling my work of art higher up the address ladder, I tried ORG 0Xhhhh but it laughed at me, and manual did not seem to list the command.

    Whats the right syntax for org?

    Default So many bootloader, so many solution...

    You can use

    DEFINE LOADER_USED 1
    OR
    DEFINE RESET_ORG 0h (for PIC 18F)

    (both are in the manual)


    Then I suggest to have a look at my personal favorites:

    -Tiny bootloader: http://www.etc.ugal.ro/cchiculita/so...bootloader.htm

    -Colt bootloader: http://mdubuc.freeshell.org/Colt/

    Yeah but...
    the OP use PBC, not PBP, so the Define Loader don't seems to be supported... unless i overlooked something.
    The OP asked for USB bootloader...

    Not sure if you can use a bootloader with PBC...

    Get ready GrandPa for some more snow tonight

    My only magic link will be Melabs support.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    emmmmmmmm

    odd result here, if someone wants to take a stab at an explanation.....

    I used ''DEFINE RESET_ORG 10h'' and the first thing in my code was ''@clrwdt'' followed by a few more...

    So I expected.....


    0008: FFFF FFFF FFFF FFFF
    0010: 0004 0004 D7FA

    but got

    0008: EF0A F000 0004 0004 D7FD


    emmmmmmm, at least its moving the start, so I can jiggle that to where it needs to be.
