Hi waterwingz.

Yes. i confirm that your version for FW 1. F did successfully take regular *.jpgs and *.dngs!

Have an example look here: http://www.dobermannfan.de/digipix/IMG_0101.JPG

or here: http://www.dobermannfan.de/digipix/CRW_0101.DNG


@HankeyPoo:

A 495 FW 1.00 f did make 2 badpixel-picts; very slow; thought it was frozen, but it did work to an end and created a badpixel.bin in chdk folder.

Must end now; snooze alarm starts at 4:48....


regards
IXUS60/SD600, FW 1.00A; Powershot S95, FW 1.00H; Powershot A495, FW 1.00F;
sometimes IXUS100 IS, FW 1.00C; infrequently IXUS80 IS, FW 1.01B

I've been working on an enhanced version of finsig/gensig that is giving me very good results so far.
If you can post your platform/a495 files (and all the subs directories) I can try my signature matching algorithms and see if it picks up anything.
Will do.    And when you get there,  it would be nice if you would let me upgrade the finsig/gensig in CHDK-PT with your code.  Right now its just using a modified version of the stuff from the trunk\trunknnnn\tools directory with a couple of different instruction patterns thrown in for good luck.

Excellent news - thank you for your help !

This means that while some of the stub_entry_2.S values are questionable,  thats not the problem with the 1.00e port. The 1.00e and 1.00f reference the same routines (although some are slightly shifted in memory). Now I need to find somewhere else to look for the problem.

Yes, I was thinking we should combine our efforts at some point.
I'm working on a signature system that doesn't get run every time you build - it would use a much larger database built from all the working versions and would be used to create an initial port. Like what you've done with chdk-pt; but for when you're starting from scratch with a new camera.

Phil.
CHDK ports:
  sx30is (1.00c, 1.00h, 1.00l, 1.00n & 1.00p)
  g12 (1.00c, 1.00e, 1.00f & 1.00g)
  sx130is (1.01d & 1.01f)
  ixus310hs (1.00a & 1.01a)
  sx40hs (1.00d, 1.00g & 1.00i)
  g1x (1.00e, 1.00f & 1.00g)
  g5x (1.00c, 1.01a, 1.01b)
  g7x2 (1.01a, 1.01b, 1.10b)

Do you ever worry that if we make this too easy,  everyone will be able to do it and we lose all our mystical status ?

Actually,  that would be kind of nice.

On an unrelated note,  I believe I've found the problem with the 1.00e.   I don't want to admit it but its more bad code creeping in from the broken 1.00d port.  PEBKAC again - sigh.

Okay - here we go again - beta12.

CHDK for the A495 firmware 1.00e - Beta12

I have not cleaned up the stubs I pointed to earlier today so some functions may not work.  But this one should boot and take pictures at least.  :D

    * Raymond Passworthy: Oh, God, is there ever to be any age of happiness? Is there never to be any rest?

    * Oswald Cabal: Rest enough for the individual man, too much and too soon, and we call it death.
But for Man, no rest and no ending.
He must go on, conquest beyond conquest.
First, this little planet and its winds and ways.
And then all the laws of mind and matter that restrain him.
Then the planets about him, and, at last, out across immensity to the stars.
And when he has conquered all the depths of space, and all the mysteries of time, still he will be beginning...

Just like porting cameras to CHDK when you do not have them at hand   :)

Obscure HG Wells movie reference.   Probably more fun to quote in the pre-Google age though.

I'got a photo taken with chdk with my a495 1.00e!!!!!!! :) :) :) :) :) :) :)

All this is possible because you have worked on the port until the end!!!



THANK YOU WATERWINGZ !!

MUCHAS GRACIAS

here you have the first dng taken with your port:
https://intercambio.upv.es/download.php?id=0e82a630ac05c06eabc46eb71a20e20e
(it only will be a week there)

Note:

The script badpixel  is  working correctly. But the strange thing is that during a time the camera has no light and seems to be dead, but later returns........

Wow so nice to hear... maybe WaterWingz will try help port to 100d too when this is working... that i hope :)

What size of SD card are you using btw? will it be possible to use a 16gb card with with CHDK? i have readed it is possible to make a small partion for CHDK to run and then use the 2nd partion to save the pictures on. any change you can test that?
