UPDATE

ok, stubs_entry_2.S was all wrong, here is the rework source:
Code: [Select]
#include "stubs_asm.h"

// search your fw dump, look at stubs_entry.S & stubs_entry_ida.S (execute scan-event-procedures.idc in ida to create)

NHSTUB(MFOn, 0xFF98FBF0)
NHSTUB(MFOff, 0xFF98FC20)

//NHSTUB(DisplayImagePhysicalScreen, 0xFF95F73C)   // note "ImgDDev.c" / aImgddev_c ?
NHSTUB(Open, 0xFF87B55C)   // before Close()
//NHSTUB(Close, 0xFF87B584)   // note "Close" / "aClose"
//NHSTUB(Mount_FileSystem, 0xFF87A8AC)   // note "Mounter.c" / aMounter_c
//NHSTUB(Read, 0xFFB57BDC)    // after Remove()
//NHSTUB(Write, 0xFFB57C4C)   // after Read()
NHSTUB(free, 0xFFB5ABC8)
NHSTUB(Rename, 0xFF87B644)   // after Write()

NSTUB(kbd_p1_f, 0xFF827F58)
NSTUB(kbd_p1_f_cont, 0xFF827F64)
NSTUB(kbd_p2_f, 0xFF82833C)
NHSTUB(kbd_pwr_off, 0xFF829238)
NHSTUB(kbd_pwr_on, 0xFF8291F8)
NHSTUB(kbd_read_keys_r2, 0xFF828D40) // search for "MOVL    R4, 0x223000"

NHSTUB(AllocateMemory, 0xFF81AC70)
NHSTUB(FreeMemory, 0xFF81AC5C)

NHSTUB(SetPropertyCase, 0xFF825778) // see "PropertyCase.c" and refs to it

// null stub (RET):
NHSTUB(SetZoomActuatorSpeedPercent, 0xFFFFFFFF)   // dummy, not found yet

NHSTUB(GetDrive_ClusterSize, 0xFF87AD70)   // note "GetCatFs_ClusterSize"
NHSTUB(GetDrive_TotalClusters, 0xFF87ADAC)   // note "GetCatFs_TotalClusters"
NHSTUB(GetDrive_FreeClusters, 0xFF87ADE8)   // note "GetCatFs_FreeClusters"

//NHSTUB(UnsetZoomForMovie, 0xFF83656C)
NHSTUB(ExpCtrlTool_StopContiAE,  0xFF91F0FC)
NHSTUB(ExpCtrlTool_StartContiAE, 0xFF91F0CC)
NHSTUB(MakeAFScan,  0xFF993BE4)

// --- has ALT in stubs_entry.S
NSTUB(GetCurrentAvValue, 0xffb0f210)Some Function where already found by IDA, found some myself and some found by compare disasseble from sd900 and sd800...

Still no change at all... this s**cks...  :'(

Sweet, I have an SD900 and would love to get CHDK on it.  Thank you to those involved in development.  I'm going to read up and with any luck, get CHDK deployed on a my cam and then show it to all my buddies with Powershot cams.

I'm still working on it sometimes...but no major progress yet...
I'm very frustrated...

I'll post here ASAP if there is a breakthrough or developent is discontinued!

You have to be patient...
or
Get me some usefull informations (i've read a lot, searched around, looked for other ports, ...)
or
You have to dig into yourself...
or
Motivate somebody with more experience to help us...

Sorry!

UPDATE
As requested by "tailgate" via pm i've uploaded the current source. Grab it here: chdk_sd900_100c_trunk579_pd_beta_v4_20081125.7z - 3.09MB.

Maybe together we will get this port to work... Looking forward to some usefull input  ;) .

NOTE:
  • trunk579\platform\generic\main.c
    i've disabled some functions, even this stuff should be correct, but i can't test it yet.
  • trunk579\platform\ixus900_sd900\sub\100c\boot.c
    i've commented where camera stops...

Keep on CHDKing folks!
