Hello

Starting porting the ixus70_sd1000 ver 102a here are some files to download that i found out. Not sure of everything is correct. I have til now no idea for the file lib.c. I hope some of the developers can help me find out the right values.

btw i also start porting the ixus850_sd800 100e. I will upload files next week.

{
    return (char*)0x10E706A0; //(0x10E70000 + 0x6A0) (find on ".crw")
}

long hook_raw_size()
{
    return 0x8CAE10; //7mpx (0x8C0000 + 0xAE00 + 0x10)(find on ".crw")
}

{
    return (void*)0x0;
}

}

void *vid_get_viewport_fb()
{
    return (void*)(0x1065BA50); //(find on "VRAM Address  : %p")
}

{
    return 360;
}

long vid_get_bitmap_height()
{
    return 240;

{
    return ((mode_get()&MODE_MASK) == MODE_PLAY)?240:230;
}

Hi

Some success. I can compile the firmware and the camera start with blinking blue led splash screen and chdk running.
I can navigate through the menu, change values like osd raw parameter etc.

Everything works as far as i can see.

Here is the Problem.
1. I cannot start the games.
2. When I try to make a picture the camera shuts down and no picture were save on sd card.
3. When I try to make apicture in raw the blue led lights for a few seconds then the camera shuts down. The crw image is saved in \DCIM\000CANON\  as CRW_0001.CRW. After restart when I make a new picture in raw its again saved as CRW_0001.CRW - the first picture is lost.

Here are the files i use for compiling.

Here is the primary.bin

Try other value for  PARAM_FILE_COUNTER in shooting.c (probably 0x37).
And you can reduce functions in capt_seq.c to its original versions (for example, instead of  sub_FFAFECD8_my call simply sub_FFAFECD8). Maybe, copy-paste error?

Hi

The Camera still shut down after i take a picture. But now the raw image is saved in \DCIM\100CANON\ with the correct file name CRW_0220.CRW, CRW_0221.CRW ...

Taking jpeg still don't work. No image saved and shutdown.

I also have to say that there is no playback on the lcd after shooting. any other idea

thanks quietschi

Hi

i changed first

"BL      sub_FFAFECD8_my\n"  to  "BL      sub_FFAFECD8\n"

image playback works, files were saved as jpeg, but no raw file saving, also after changing both

"BL      sub_FFB01EB0_my\n"  to  "BL      sub_FFB01EB0\n"
and
"BL      sub_FFAFECD8_my\n"  to  "BL      sub_FFAFECD8\n"

So i check my capt_seq.c

thanks quietschi

Hi

The file numbers are ok now. thanks ewavr

About the record/play mode detection
in misc values.

in shooting mode
1:10FF0245
2:DB20DA08
3:    EFFD
3:    EFFD

in movie mode
1:10FC0245
2:DB20DA08
3:    FFFD
3:    FFFD

in play mode
1:101F0240
2:DB20DA08
3:    BFFD
3:    BFFD

the values are not constant, they change several times in a second like 3:    BFFD - 3:    BFFE

I'm not sure wich values to use
