DryOS - some success

[Ekscel]

It seems work fine but the alternative menu only shows me the script menu. Do I make a mistake ?

Maybe you press "set" button instead of "menu"?

Latest Allbest build for a720 here - http://malbe.nm.ru/chdk/allbest-a720-100c-31.zip
Also small program, which makes SD card bootable (for WinXP/2000) - http://ewavr.nm.ru/hdk/bootable.zip

What does mean? i did not understand nothing 

These steps to make bootable the sd and more is to get the chdk into the camera or what??     how do i make bootable my sd? i dont know use that program..

It is very easy:
1. extract from above bootable.zip the "bootable.exe" file
2. put your SD card into reader or SD slot in computer and copy bootable.exe to the SD card
3. SD card behaves as disk and has assigned some letter (for example "F:"). Run shell (on winXP: menu Start - Run..., type "cmd") and change to SD card (by typing "F:" and press Enter in this example case)
4. Run bootable.exe You will be prompt to give right syntax as "bootable.exe F:"
5. confirm and your SD card is bootable
6. copy to your SD card "diskboot.bin" extracted from above allbest-a720-100c-31.zip
7. lock your SD card (take it from computer before  ) by mechanical switch
8. put SD into Canon A720IS and switch camera ON. The blue splash screen appears
9. check CHDK firmware usage - CHDK Wiki to know what can you do with CHDK

Sorry, I hav 4GB card and windows XP. I tested your bootable.bin with small card and that works super. But with 4GB that doen't work. I cannot format one to FAT or to smaller (2GB). Could you help me?

From the Wiki FAQ:

Note2: 4 GB cards can support the autoload feature if they are formated in FAT16 manually. To format SD-card in Windows command line just type 'format X: /fs:fat' (where X: - a drive letter of mounted SD-card). But be aware that the formatting of 4 GB cards in FAT16 leads to non-standard 64K cluster size. The correct support of such cluster size is not guaranteed.

But actually, I have not heard any complains that it does not work.

I was just curious if their was anyone working on the original firmware 1.00a firmware for the s5is, or is dataghost the only one working on the s5 firmware. I thought scott was working on it but i have seen him post for awhile.

[TapouT]

He may have got busy I haven't seen him on here in awhile (geekmug, I think on these forums).  I think in an earlier post DataGhost said when he completes the 1.01b he may have a look at the 1.01a.  I luckily have 1.01b on my S5.

Don't forget though, these guys do this for free when they have time to do it. He might have gotten busy with work, family or just don't feel like programming for awhile.  I hope I can learn enough to eventually contribute to such efforts, but until then, I have to be patient and thankful that they do this to begin with.

Super!!!! A forgot old good MSDOS sentance!!!! I tryed only right-click and format under windows XP. It looks its working good with no problem on the card with capacity 4GB. Thanks thanks thanks!!!!

Hi.
I have Canon S5 IS (1.01A) and I am very interested about being able to use CHDK on it. I am willing to help, but unfortunately I don't know ARM assembly language. I know programming in C/C++ (I wrote some open source programs).
Is anything to do to help ?

If you have access to/can get access to a copy of IDA (Pro because the free editions don't support ARM IIRC);
* Run GrANd's signatures (see about page 9 of this thread) against a dump of 1.01a
* Make a 1.01a branch of DataGhosts code (duplicate the loader/s5is/101b and platform/s5is/sub/101b directories as 101a)
* Update the stubs file with the addresses of the functions IDA finds in your dump and see if you can get it to work on your camera.

I expect that the boot sequence used in the 1.01b branch should work fine on a 1.01a cam (the boot sequence is directly copied from the firmware dump (i.e. there are no references to functions which reside in the camera's memory)) but I could be wrong.

Note that this code will not build on the Windows toolchain (goes into an infinite loop and eventually crashes out), you will need to build it under linux using a toolchain built as described here; http://chdk.wikia.com/wiki/Compiling_CHDK_under_Linux

Sorry if this information is already in the thread (I did a quick scan but didn't find anything), but is DataGhost's S5IS code public anywhere?  I recently bought an S5 (1.01B) and would love to run CHDK on it.  I'm also a professional programmer (used to do a lot of C/asm, not so much these days), so I wouldn't mind getting it in a rough state and contributing back.   I can be reached at gfm@yahoo.com if the code isn't public but is email-able. Thanks!

The latest code DataGhost has published is linked in this thread; http://chdk.setepontos.com/index.php/topic,234.msg1918.html#msg1918

I believe he has the keyboard handlers working now but he's yet to publish his latest work.

I am new to this forum, i own S5, but i don't know much about programing. I would like to test releases, so if i can help in any way, please let me know.

My firmware is GM1.01A, Adj Ver.007.000, IS Firm Ver. 3.00, IS Param Ver. 3.00

Should i try to load this last release from DataGhost?
I suppose not, but, if i try, can anything go wrong permanently? (i don't think so, but would like your opinion)

Thanks for the offer.

I believe DataGhost is intending to look at 1.01A after the 1.01B port is complete, once there is a version of CHDK for the S5 porting will be much easier (structurally everything will more or less be the same, most likely the only difference will be addresses of functions that CHDK hooks).

You can try. It would, I think at least show us whether the boot sequences are compatible (I believe they should be), no permanent damage will come to your camera, most likely if it doesn't work it will just hang, in which case unlock your SD card and reboot your camera and it will be back to normal.

Hi!

I'm the happy owner of a S5is, with a firmware 1.01b.
After searching a bit, i have install the last code of DataGhost on my S5, following the same procedure than for the 720 is, or quite.
I had to take files in the BIN folder from the archive of DataGhost, the DISKBOOT.BIN file, and the s5is-101b.FIR, then copy them to the root of my Sd card, and then use the program bootable.exe (from Ewawr) under windows to make the card bootable.

Then, i lock the card, put it in the camera, turn the camera on in Play mode, and i saw that CHDK launches, because there was some numbers changing in the two up corners of the screen. But... Nothing more, actually. The camera function normally, (I mean that there is no extra functions) because it's still the version of code without the support for keyboard i think.
It turns out that the s5is-101b.FIR file is not necessary, the CHDK launches also without it.

So.. It's good to see that CHDK launches, but it doesn't give anything currently. 
Still.. I'm sure that it's on the good way, and i would like to already thanks DataGhost and all others programmers working on the porting of CHDK to S5is for all the works they are doing!

First,

My thanks to everyone here involved with CHDK. I am both amazed that anyone figured out how to dump and disassemble code from a digital camera and all of the functions that have been created.

I have the first release (?) of Allbest's v16 DryOS code loaded in my A720is (yippee!) and found two small issues.

1. With a 4GB SDHC Sandisk II card formated with FAT 16 (format e: /fs:fat on Win-XP). Everything seems to work OK, except saving the CHDK/chk.cfg file. Turns out that neither the file or file system (CHDK/BOOK /FONTS /etc...) are being created on the 4GB card. I tried a camera formated 16 MB and a 2 GB SD  card and both worked fine (directory structure and chk.cfg file were created--however, the CHDK.CFG file was created/modified with a 01/01/2000 12:00 AM date and time). By copying the directory structure (and file) over to the 4 GB SDHC card, the camera was able to "remember" OSD settings just fine. I have yet to play with the other functions (book, scripts, etc.) to see if they have FAT16 issues or not. The camera seems to be making JPEG files just fine. And I have shot a couple RAW pictures too (have yet to load any software that can open RAW).

2. The other minor problem is that Zebra/Blink mode does not map on the screen correctly when using Digital Zoom (paints roughly 1/4 screen to the left and up a bit with respect to the LCD feed). Not a big issue--can shoot with only optical zoom and Zebra maps on the screen just fine.

Sincerely,
-Bill

1. Try this version with increased startup delay - http://www.zshare.net/download/6914475366a739/
2. This is normal for CHDK
