ixus90/sd790 IS porting

[scottydont4444]

1.00c showed minimal differences and some minimal shifted address areas.
I tried to adapt the necessary code, but obviously can not test it.
If anybody can give some positive feedback this firmware version could be added to the CHDK trunk.

Kind regards

I was able to load the firmware to my camera (1.00c) and was able to navigate around the CHDK menu. However, every time I went to take a picture, the camera would freeze up and it the light would just keep blinking.

1.00d
My recent changes:
- fixed a bug with dark frame subtraction (nrflag was incorrect)
- improved USB remote support
- cosmetic changes (I hope patch verification is not too confusing)

I think it's good to add it to the trunk.

1.00c
The new binary contains my last improvements for 1.00d (dark frame, USB)

However, every time I went to take a picture, the camera would freeze up and it the light would just keep blinking.

Hmm. Which color is blinking? How long? Is save RAW active? Any other CHDK overrides active (usually in red color in the top left corner)? Do you have to turn off and on or remove the battery?

I'll fool around over the next couple of days, but is there anything specific that I should look for?

e.g. take a picture  

The changes compared to 1.00d are in:
boot, jogdial (in CHDK and Canon mode), movie overrides (bitrate, quality, change during record), ND filter override, ultra long exposure (>64s),  ..
So it's good to test this.

Thanks for your feedback

It turns out that the override shutter speed got turned on. So it was taking a picture, it was just taking a very long time. I did notice that there is also a 1.00c patch. How do I install that?

Updated the CHDK trunk with ehmu's latest code: --> changeset #870
- added 1.00c (reply #273)
- corrections for 1.00d (reply #286)
- added 1.00e to the makefile (copy of 1.00d)

The latest binaries are available from the autobuild server, as always...

The autobuild server now serves 3 ixus90_sd790 versions:

• 1.00c
• 1.00d
• 1.00e (where 1.00e is simply a copy of the 1.00d version, it will also report 1.00d in the splash screen / CHDK fw info box)

@ehmu:
Are there any additions/corrections for the 1.00c version ?

[ehmu]

@fe50
Thanks a lot for merging all the patches so far.

For 1.00c I recommend the added patch:
+ correction of dark frame subtraction override
+ improved USB remote support

Done. (changeset #872)

I need to update to the latest firmware, but one odd thing I noticed is that if I tried to bracket exposures while shooting RAW, the camera would freeze and then shut off after the first picture.

I noticed this as well. My camera usually made it to the second picture but then froze up and shut off.

.. if I tried to bracket exposures while shooting RAW, the camera would freeze and then shut off after the first picture.

I can confirm crashes with raw (and dng) bracketing, but can not reproduce
it reliably. Bracketing with jpeg only works.
Most crashes I got after 3 pictures with 1/3Ev + bracket type, 1/5s Start Tv. It seems
as my slower SD card does not crash (at least less often).

I also get no crashes when I activate the continuous mode via the custom timer (icon with C) and then just have to press once to release the specified number of raw shots. When I use the continuous mode with the stacked rectangles icon, I have to keep the shoot button pressed - till it crashes.

I put the latest build (874), which is no longer beta (Yay!) onto my card and the camera would no longer boot.  Cardtricks went crazy and I tried several things and nothing worked, until I replaced the current DISKBOOT.BIN with the one from February 6th.  It will boot from every other DISKBOOT.BIN file I tried it with, just not the one from build 874.  Does this present a problem that needs to be addressed, or does this file truly only allows the camera to boot from the card.  Every file is a different size, which makes me ask the question.

Cardtricks went crazy

Can you explain what you did, and in what way CT went crazy ?
If you found a bug in CT, I'll gladly fix it; if not i should be able to explain what went wrong (i hope)

thanks,

wim

I opened up CardTricks and it ask me to browse to the card, which I did, but it kept asking me to do the same thing, ad infinite-um.  The only way I could get out of this loop, was to stop it through the Task Manager.  I tried it twice, thinking the first time was just a glitch, but, it wasn't.  Hope you're successful in getting this fixed, it worked before for me about a year ago.

@NormanA

You're the second person to report this behaviour (from ~ 100.000 downloaders)
When the first person reported this, I was mystified, but after some exchange of
posts we determined the reason. So, here's my guess:

You moved the program - and forgot the CardTricks folder with helper files, which
should be in the same folder as CardTricks144.exe (as in attached pic)

Solution 1: find the folder & reunite with the program
Solution 2: redownload http://savedonthe.net/download/78/CardTricks-144-SFX.exe

HTH,

Wim,

I checked my CardTricks folder, and found that I had indeed used the wrong file to open the program.  Thanks for the information, however, I now, also realize that the problem is with DISKBOOT.BIN, it's not working, unless I use one of the other files from a previous build.  They all work fine, but, not the one from the current build.  Am I losing functionality by using this older file with the newer build?  The size of the new file is 263,668, dated Feb. 13, 2010.  The latest one that works has a size of 252,729 and is dated Feb. 6, 2010.
