the sx20 porting thread

The file I downloaded from the autobuild listing was named "sx20-102b-0.9.9-902-full_BETA_without_games.zip"

Not a AB server package - that's the manually compiled test package i provided in reply #674 😀

Hmm. My fuzzy old head is starting to hurt now....

I thought I saw it in the AB listing. However, I guess not. My apologies for my confusion.

Anyway, it was the 902 version I was using at the point where I became aware of the whacked numbering. I've not figured out where it came from, but it straightened out when I deleted the CCHDK.CFG file and the CANON folders. It's not clear which was required.

Between us we have two SX20's that open a new folder whenever the camera is turned on and one SX20 that does continuous numbering normally. It would help us to rule in or out some hypotheses if you two would let us know which version of CHDK you're using.

Think I may have found a way around the multiple folder creations and file numbering.

Settings as follows...............

RAW file in dir with jpg ..................OFF
Raw file prefix...............................CRW
RAW file extension........................CR2
Raw subtract pref..........................IMG
Raw subtract exte.........................JPG
Bad pixel removal.........................RAWconv
DNG format..................................ON
'DNG' file extension.......................ON

JPG files are now added to an existing folder with 'continuous numbering'.
No new folder created.
Raw files (DNG) all located in the 100CANON folder. No new RAW file folder created.
Have just tried this method out (4 times) and it seems to work!!
The only anomaly I have found is that when turning on the camera the "available DNG files" is v high - this changes after the first image taken, to a true (lower) figure.
Try it out and see if it works for you.
I'm using CHDK vers 902

I started with the first setting in your list and tested both 885 and 902 and both resulted in the numbering problem you mention. I don't enable the "RAW file in dir with jpg" because I only use DNGs - I mention why in the other tips section of my "DNG or RAW" document (http://rapidshare.com/files/390852020/DNG_or_RAW.pdf) In both versions I started seeing the numbering problem after (1) enable "RAW" and "RAW file in dir with jpg", (2) shoot photos, (3) turn off the camera, and then (4) shoot more photos.

Appears enabling the "RAW file in dir with jpg" might cause the numbering anomaly.

RAW file in dir with jpg ..................OFF

works.

I don't used this setting because i had problems with corrupt dng's with it.
But now it works, and the dng's are korrekt. I can't say why.

It's great.

In the sources i have found that raw_saving() calls get_target_dir_name() which calls get_file_next_counter() with the following operation: (file sx20/shooting.c)
n= get_file_next_counter(); // 4 Bytes from parameter 0x38
n= (n>>1😎&0x3FF
in most other camera types the operation is
n= (n>>4)&0x3FFF

Is there another format on the sx20 or could be there the problem?

Get the impression you have not activated "Raw file prefix" and "Raw file ext' - suggest you activate both with CRW and CR2 respectively. Both DNG lines should also be activated. It will produce DNG files NOT CRW or CR2 files.
Was out this morning - camera on and off six times.....................all images went to an existing folder(numbers starting from the LAST image in that folder) and the DNG files were in the 100CANON folder.

Hope this helps and it works for you..........Terry

Glad to see it works for you - cannot comment on your program code comments - I'm thick when it comes to that area.

can someone give some hints how to get running chdk on sx20 1.02b ? https://chdk.setepontos.com/d/4348/711
My friend wants to be CHDK follower.
I explained him alot. He is excited.
But I cant switch to record mode.

edit: Actually I can help with porting if there are problems...

problem encountered in both builds: when switching to record mode camera seems to power off (power led is off).

Maybe the known problem with lack of free memory ?
Does the position of the mode dial matter ?

I suggest to try the default settings for CHDK & also for the camera; does it work with a fresh CHDK installation, without old config file, on a newly formatted card ?

Background:
the available free memory also depends on the amount of images stored on the card and the camera's settings;
maybe also zebra could be enabled in the config from an earlier test,
or some settings may have other side effects...

Reports from the german forum:
- with zebra enabled, the SX20 crashes when the shutter is presed or half-pressed, definitively due to lack of memory
( http://www.wirklemms.de/chdk/forum/viewtopic.php?p=17737#17737 )
- the camera also crashes when you try to capture a still image while video recording is active

holly shit. are you sure?

one test image on card.
erased cfg file between builds change.
did not format card. I think it was fat16 because diskboot.bin was executed.

Actually...I normally keep them activated (https://chdk.setepontos.com/d/4348/677). With the exception of enabling the "Raw file in dir with JPG", I used my normal RAW/DNG settings for testing the numbering anomaly.

Does anybody feel the current betas are far enough along to begin work on 1.02C and 1.02D? I have the 1.02D and am really anxious to get the motion detection and scripting capabilities active. Has anyone taken a look to see how different the two new firmwares are, if so does it look relatively simple or will it take awhile. Please let me know if there is anyway I can help. Thanks in advance for any insight!

Hi everyone sorry for my english, i don't speak it but I recently buy a sx20 and I wish to know if exist chdk for Firmware Ver: GM1.02D

Thanks

Hi mx3

i think the problem is the enabled "zebra"-mode. Try to start the sx20 directly with on/off button and not in playback-mode to avoid pressing "half shutter" with enabled zebra.
Then activate CHDK and disable zebra-mode in the menu, this should help.

At present i'am testing zebra without buffering to save memory.
It works very stable, but i have not everytime the zebra-shadows...

Good to know...
Pls. post the code / a diff file when it's ready for the trunk; i'll commit this & enable the AB server for the SX20...

@f_m_b

Does your build have games compiled in or not?

f_m_b

@acid2000:
I have disabled all games, calender, edgeoverlay and textreader because i don't use them with the camera.

There are times i can use zebra with this disabled options, but most of the time the sx20 crashes while pressing "half shutter".
With the non buffered zebra i have no crashes (i can check it with the enabled options and give a short report) the disadvantages of non buffering are a flickering histogram and sometimes the zebra-shadow doesn't appears. I try to fix it.

I have an 8Gb high speed card. I cannot get this damm card to work. I used sdminste to partition, put the files in the right spot and...nothing. I get an upgrade error when doing it manual load and a card locked error when trying it autoload.
It is partitoned exactly the same way as my 4Gb cards...I even cloned everything over to the 8gb from the 4gb just to see..and got the 'card full' error. Also getting an 'E18' when doing the version check.
Is it the high speed that is causing the issue?

I get an upgrade error when doing it manual load and a card locked error when trying it autoload.

The SX20 doesn't support manual loading (with "Firmware Update" from the Canon menu), therefore you'll get an error; only automatic loading is supported.

The "card locked" message indicates that the camera does not load CHDK (file "diskboot.bin") at all...

To (auto)start CHDK,
a) the first partition must be FAT12 or FAT16 formatted,
b) the card must be CHDK-bootable ("BOOTDISK" tag in the card's MBR at offeset 40h)
c) the card must be locked

The SDM installer should show whether a) and b) is correct.

I did all of that fe50. The card was partitioned correctly and like I said, copied over the working card files. Still get nothing. Could it be the card or should I flash the card and start all over?
