I've been testing beta4 for a while (can't get beta5 going), and I've noticed that even while not running CHDK, the manual focus often doesn't work ...
Got the camera swapped over, and the replacement did the same thing without CHDK loaded.  Appears to be a pervasive fault with the model and not related to CHDK. 

Oddly the new camera I got back was a 100b firmware rather than 100c.  Beta5 loads fine on this and is a good deal more stable than beta4.  Haven't managed to crash it so far.  Saving RAW is very slow for me too - maybe 10 seconds per shot.

It would be nice to have HDR with high speed 10fps

I found this thread: http://chdk.setepontos.com/index.php?topic=7765.0 which suggests that at least on the SX40 the camera didn't check for changed exposure time values between shots.  However it would be nice if the SX260 does things a bit differently and high speed HDR was possible. 

Oddly it seems that even on the SX40, it is possible to bracket in HQ mode by varying the aperture or subject distance, but not exposure time.  I tried aperture bracketing in HQ mode on the SX260 and it did work (though of course the variation available is limited).  Though the ISO information for each photo showed the same aperture, three photos had different brightness.

I wonder if this is some way to convince the SX260 to check for exposure changes between shots in HQ mode.

Hi, I'm working on A2300 port, and I'm having some problems with mkdir function. Something similar to problem seen with SX260.

I'd like to know if someone is using chdkptp with his SX260, and if it's possible to create dirs using chdkptp commands without error.  Thanks.

No. Error 0 (test with chdkptp and Lua) on mkdir is also available for SX260 and A590.
The created directory is permanent. There are no differences between R1={-1 | 0 | 1}. For SX260 is STUB MakeDirectory_Fut = STUB mkdir.

I don't know if this could be related to RAW generation bug, but I think that this patch in capt_seq.c is in a wrong location
Code: [Select]
      "    BLLS    sub_FF07654C \n"             //Asm1989 Looks Like
      //PATCH BEGIN  ASM1989 Looks Like not sure
                  "BL      wait_until_remote_button_is_released\n"
                  "BL      capt_seq_hook_set_nr\n"
        //PATCH END
      "    LDR     R0, [R6, #0x94] \n"

Inside the corresponding code for sx230, sx30, those functions are called before GetPropertyCase and "SsCaptureSeq.c".  So, my guess is that patch should be like:
Code: [Select]
      "    BL      sub_FF1BF828 \n"
//PATCH BEGIN
        "BL      wait_until_remote_button_is_released\n"
        "BL      capt_seq_hook_set_nr\n"
//PATCH END               
   "loc_FF1BF14C:\n"
   "    LDR     R0, [R6, #0x94] \n"
EDIT: This code is for firmware 100b

@nafraf
Thank you for your hint. It reduced the raw save time from 9 sec to 6 sec.

I think now is SX260 ready for trunk. On 100b works CHDK without any crashes on my tests. Also gps works after string fix in gps.c.
sx260-100c is untested!

changes:
- add propset5 (only PROPCASE_GPS is changed)
- patch wrong string buffer in gps.c
- universal color definitions for gps in gps_palette.h
- fix raw save time from nafraf
for all:
- fix valid color for +Misc mode in gui_osd.c

Patch based on trunk 2034.

We all like cross postings. ::)

I know and I am sorry but this tread is more active than the sx240hs.
I guess that when the sx260hs will be ready then the sx240hs will be as well. Oh god can't wait to have RAW and time lapse! A! HDR will be nice as too.

The two have nothing to do with each other.  Each port is a unique effort and requires a developer with the right skills and time,  usually somebody who actually owns the camera.  Please read this:
