    I had some spare time this weekend, and i have been reading up on my Python.
    So i set the goal for adding debugging support for SPU proccesor in ida, since the procs. is written in Python.

    Download the package at the buttom and overwrite the files in ida dir.

    You can edit the line in gdb_arch.cfg if you dont have ida in c:\ida

    Code (Text):
    set QEMUPATH  C:\ida\plugins\SpuDebug
    to what ever you have.



    You have to have Python installed correctly
    see Please login or register to view links
    for help.(there are finished packages there somewhere)

    first set system environment setting

    PATH
    add ;cygwin\bin

    make new one called

    IDADIR
    c:\ida

    Turn Firewall off when debugging or pass it throug or it wont connect.

    restart PC

    okay fire up ida and load a spu.elf file.
    choose spu proccessor

    Right away after its loaded you would notice that we can selct debuggers, the original spu dosent support this.

    I code so it start with the remote gdb debugger since this is what we need,

    we have to setup some small stuff before we start
    press debugger options at the top.

    [​IMG]

    tick run program before debugging and choose configoration.

    [​IMG]

    Now i have made two options we can choose from.

    Debugger or dump ls

    We start with dump since its the fun one.

    [​IMG]

    press ok ok ok.

    i will give a short explainasion later.

    press run the green arrow and it dumps the ls.bin

    [​IMG]

    now we test out the live debugger option
    We chosse under debugger settings again.

    IMPORTANT !!
    we have to have max package size set to 1024

    [​IMG]

    press ok

    tick stop on debugging start it seems to be the most stable.
    then click edit exeptions in the buttom.
    [​IMG]

    Locate SIGABRT and press right click edit and untick stop.

    You press the green arrow again to run or
    set Breakpoint and run to cursor.

    :cool:

    success

    We can now write custom anergistic to do spesific needs.
    Remeber anergistic is basicly gdbserver in a shell.

    Little more about the Dumper module
    I use a custom version off Anergistic.

    that works with patching my way throug a spu file.

    when loaded any spu module it loads a spesial patcher module also.

    Credits to computerline :)

    You find it under views>> subview >> patches.
    press that.

    [​IMG]

    under edit >> patches you have two new options.

    selct the jump in graph view and select edit selction.
    [​IMG]
    patch

    and go to patch windows >> right click and refresh

    [​IMG]

    Now dump that ls.b ;)
