mkdir  seams to work, but I have to modify the original wrapper.c,
Code: [Select]
long mkdir(const char *dirname)
{
return _mkdir(dirname);  //asm1989 TESTING
//return _MakeDirectory_Fut(dirname,-1); // meaning of second arg is not clear, firmware seems to use -1
}
Is there another way to do it without modifiing the original generic\wrapper.c ?

Target dir shows (not g12 yet) : A/DCIM/%03dCANON, will try G12 version


Also I want to use the playback button to start chdk menu instead of video:

KEY_DISPLAY is the same as KEY_PLAYBACK ? 
and how do I set up the delay so if you press some time start chdk and short normal usage?

Yes, put an NHSTUB override for MakeDirectory_Fut into stubs_entry_2.S (use the address of mkdir). If mkdir really only takes 1 parameter and the original MakeDirectory_Fut takes 2, it shouldn't cause problems (the second one will get ignored).

If your cam has both a DISP and PLAY button, then not.

I may be wrong, but it's handled by the CHDK core, you don't have to care about it.

I noticed in the ixus230 kbd.c is using some additional code to handle the hold video button press. Maybe you need to do the same thing if it doesn't work by itself like on other cameras.

thanks srsa_4c

Tryed the NHSTUB first, but hangs and dosnt create the directories I thought it was due to the second parameter?

Sorry yes sx260 has DISP and PLAY, I will try to disable play to find its numbers with onscreendebug

Funnel I was using REC as the chdk menu but then even If I switch to video record mode the shutter acts for taking pictures instead of record video, so need to change it.

I'm also working with the modes and find 2 new for this cam that should go in modelist.h (someone who updates it anytime)

Code: [Select]
    MODE_SCN_SOFTFOCUS     , // sx260
    MODE_SCN_SMOOTH_SKIN   , // sx260

If so, that's probably due to some thumb->arm magic (never looked into those). Try to encapsulate mkdir into a platform function (wrappers.c for your cam), and use that in the NHSTUB.

In your platform kbd.c, in my_kbd_read_keys() filter out the ALT button, as some other ports do, after if (kbd_process() == 0)

srsa_4c  I will try to encapsulate it

The CHDK button changed correctly to PLAYBACK soft press, and video gets back to original use

The Video quality change seams to work well, only hangs If I enable the remove time limit, need to check it.

Included all the Modes in shotting.c too.

Attached latest sources & bin ( alpha testers welcome to test out what works and dont)

Only works autoload up to 32GB SD,

I will need some of the chdk gurus to see why FI2 dosnt work to manualy load CHDK
 ( I have a 128GB SD I cant test since it's exFat and autoload fails)

The problem seems the FI2 format has changed in this cam, since the keys seams right.

About the RAW stuff only works for now If you create each time you start the camera a badpixel bin (its 0bytes dont know why), and If you have a folder 100CANON created.

I think this maybe wrong:

Code: [Select]
#define PARAM_EXPOSURE_COUNTER  0x02
since monitoring the parameter 2 dosnt change with diferent exposures

The firmware mkdir function takes two parameters so this is not likely to work properly.
The firmware seems to call mkdir with values of 0 and 1 as the second parameter.

That's the default used in the raw code when you don't specify the option to save the raw with the jpeg.
I meant put in a diagnostic that calls get_target_dir_name and display the result (best place is in the gui_draw_debug_vals_osd function.

I can call the mkdir with only 1 arg,   

in lolevel.h the definition of mkdir includes only 1 parameter, changed to test:
extern long _mkdir(const char *dirname,int unk);

But It dosnt seem to be the problem with raw stuff, looks to be related to

get_file_next_counter  or get_target_dir_name

Since it crashed I cant use the debug osd I use
Code: [Select]
  int fd2;
     fd2 = open("A/test.dat", O_WRONLY|O_CREAT, 0777);
write(fd2, dir, strlen(dir));
close(fd2);

GetImageFolder in sx260 @FF187254 finsig, looks like having more parameters than in other cams like sx40?
sorry  looks the same

trying to trace back the starting error in raw and looks like its in  _GetImageFolder or get_file_counter

Romlog is
