the sx20 porting thread

neszt

Hello Viulian!

I'am glad to see, you have success on modifying the sourcecode and got comfortable result. 😀

Please keep in mind, that i try to avoid any modification outer of SX20 port (for example gui.c). Anyway, thank you for your notice on font size, and other problems, this helps me, becaue i have no other camera to compare CHDK with. The next couple of days i'll update the git repository to reach the actual svn revision, and i'll check out your suggestions also. My actual aim, to keep the SX20 source as clear as i can for the sourcecode maintainers, to make their work easy when they decide to merge this to the main chdk branch. You can make my life easier, if you post diff, instead of part of modified source with comments.

Please feel free to send more bug and bugfix later on.

}[/code]

the jog dial line appears commented out. However, it makes no difference if I uncomment it - camera software also gets the results. I assume it is commented out due to some non obvious reason. 😳

The obvious reason is, that the Jogdial task is not implemented yet. 😀

Thanks,

Also, has anyone tried making the mods to the PTP interface

https://chdk.setepontos.com/d/4338

I have a working version with my SX1 and it is SO cool. Has anyone built a version of CHDK for the SX20 that can utilizes these special features in the PTP mod?

I'll check this out in next days, thanks for suggestion!

Hello everybody.

I have a canon sx20 1.02B and I'm trying to port neszt code to my firmware
.
.
.

I have some knowledge of assembler and C but I'm not sure of how to proceed, can you give me a hand?

Good news!

If you stuck in any problem feel free to ask questions.

😀 Thank you for the kind words neszt.

About the font sizes: I saw photos on how chdk looks on other camera; because all the grids / games were displayed on the left hand size of the screen - it did look like a scaling issue. Unfortunately, I don't know how to modify it so it doesn't touch gui.c file - if I change just a bit the defines to adjust, things don't look good.

Anyway, I do feel that the gui.c needs a bit of improvement (I mean why would it only scale for games - but not for the other parts of the menus?) when is clear that for Sx20 grids and main menu also need scaling? Probably Sx20 is a camera where you want to also scale everything, not only the games.

Or maybe you can set the LCD screen dimensions from the beginning to be 360x240 (in lib.c) instead of the real ones, then activate the scaling globally then in the #defines let all adjusts be the 'real' size (360) or 2. I think it may behave correctly in this case.

I am very busy these days, I cannot send the patch yet - probably in the weekend...

I've never developed in asm before but my background is in C. I don't have the equipment necessary to dump the firmware and the camera I have uses the sx20 is 1.02b firmware. I looked at both copies that have been posted on the board and there are discrepancies between them. If someone can push me off in the right direction I'm more than willing to commit time to porting on the 1.02b firmware.
If anyone else has any improvements on this I'd like to coordinate our efforts so as to not waste too much time duplicating the same thing.

The firmware dump for sx20 1.02b is available from here:

http://chdk.neszt.hu/bin/sx20_102b.7z (dumped by xavan)

This firmware is crc ok, and looks good (Strings.txt attached)

If anyone else has any improvements on this I'd like to coordinate our efforts so as to not waste too much time duplicating the same thing.

itsgeektime sent several post regarding porting 1.02b. His last post about the end of January:

Hello everyone

I am more than interested in upgrade my SX20 and verify that it is a good camera before putting it on sale. Could you tell me step by step as well 1.02bo firmware update if you know a video to show it.

Greetings to all from ARG

Hi guys!
Can you tell me if the firm update for SX20 include a solucion for superfine compress???
Sorry for y cuestion , im a newbie on this!!!!!
thx.-

Hi,
at the moment I´m going to get desperate baecause I don`t find a way how to get CHDK beta on my Camera. I have the SX20 with firmware version 1.00F.

here my steps I´ve done:
1. Making my 4GB SD-Card bootable by Cardtricks
2. I downloaded the beta CHDK from http://chdk.neszt.hu/bin/ -> CHDK-sx20-100f-0.9.9-866.zip
3. I unpacked these Zip-archive and copied DISKBOOT.bin onto the SD-card
4. now I locked the Card and tried using CHDK.

Is there any ps.fi2 or a solution how I can make CHDK starting automatically (I believe it doesn`t work with Cardtricks because there isn`t a final version)

please help me! I have already done the progress some months ago on another card but now this card doesn`t work any more and I can`t remember what I`ve done once. I believe that I got a ps.fi2 but I don`t find one anywhere.

Thanks a lot
Stefan

Tell me, where you can download the CHDK for SX20 IS version 1.02B

I got the sx20 1.02b booting sort of. Using the update method it reboots and shows a E31 in the bottom lefthand corner of the screen then shuts down. I don't know if I should commit this, or if anyone else has gotten further than this. But I'm pretty excited about the progress now.

ldsdave

I still have the E31 error, however now it shuts down after printing a brief message on a red background about the firmware.

edit: The firmware message is a three line message concerning the CHDK Firmware 0.9.9, build date, and something else I can't make out because it goes away too fast 😀 That's a bit closer now.

I recently loaded the neszt version (in 1.00F FW version) and I also had the fonts size problem. Instead of touching the source code (I am not very competent on that),I chose to use a bigger font size. To make things easier on this matter and help future similar problems, I propose to include o configuration (.cfg) file, in which any change in appearance, colors and other parameters will be easily stored and transfered. By the way, colors in the color matrix do not appear correctly. Still testing... and will report on any problems

I originally posted this in the windows gui shell thread and was told this thread would be best for this question.

I'm trying to compile neszt January 31 code with the shell but get the following errors:

loslib.c: In function 'os_stat':
loslib.c:298: error: 'struct stat' has no member named 'st_dev'
loslib.c:300: error: 'struct stat' has no member named 'st_mode'
loslib.c:309: error: 'struct stat' has no member named 'st_atime'
loslib.c:331: error: 'struct stat' has no member named 'st_blksize'

G:\CHDK\gcc4\bin\gmake.exe[1]: *** [all-recursive] Error 1
gmake: *** [all-recursive] Error 1

Does anybody know why I'm getting this error and how to fix it? I do have programming experience but I'm a newbie with CHDK.

I'm using version 2.70 of the shell on a windows XP machine.

Thanks for any help.

Good job! Thumbs up for your effort!

What you see, is part of the CHDK splashscreen. Normally, wenn CHDK starts up, you see this text, including the CHDK Logo (loaded from SD-CARD). It looks like that the SX20 behaves like the G11 if you try to start CHDK via firmwareupdate method: The original sw detects somehow that something is "not normal", shows an error message and shuts down. I also get sometimes the "Card is Read only message", so it looks like that the sd-card access is not working at all in that case. The only way to get CHDK working (at least for the G11) is to avoid the firmware boot method and use the diskboot.bin method instead.

ldsdave

I haven't been able to get it to use the autoboot method. Out of curiosity what does the partition look like using hexedit?

that's the relevant piece that I have on mine.
When I try locking the SDCard it just freezes and does nothing. If I take it out I can start it up normally without taking out the batteries.
Thanks for any help.
