I know, that's what I did, still gave a crash at that point. Will test more tomorrow.

Try moving the raw hook right after
Code: [Select]
BL      sub_FF99C6C0but before the label.
Can you upload one of those bad DNGs? The first 100kB or so is probably sufficient.

That's what I first tried and it didn't work (skips raw saving altogether), I will retry since I saw I made a typo in my code.

Here is a DNG header that I got without the Dvlp hook.
Made with
Code: [Select]
head -c100k CRW_...DNG
Edit: putting it before the label doesn't crash the camera, but it doesn't save it whether I select RAW or DNG.

That's very odd because that seems to be (almost) equivalent to the spot used in the sx170 port (which is known to work).
You could try some debugging (below snippet is just a suggestion):
Code: [Select]
"loc_FF99BD38:\n"
"    LDR     R0, [R1, #8] \n"
"    MOV     R1, #1 \n"
"    BL      sub_FF99C6C0 \n"
"BL debug_func_1\n"
"loc_FF99BD44:\n"

(...)

long debug_func_1(long x) {
  *(int *)(0x40000000) += 1;
  return x;
}Print *(int *)(0x40000000) somewhere on the screen and see whether it's increasing as you shoot.

edit:
your DNG header snippet has suffered an LF -> CRLF conversion (a 0x0d byte is added before every 0x0a byte)  :blink:

nope, doesn't increment at all. Will investigate more this weekend.

As for the crlf issue, cygwin is to blame I think :(
Trusty ol' dd to the rescue!

Sorry for the zip, forums doesn't want me to upload files with weird names

In this case you'll have to discover what happens when you shoot, in the following tasks:
- capt_seq
- dvlpseq
That usually means logging of the so-called messages received by those tasks. My debug patches made for the sx170 may give some ideas (if not, please ask). See this year's attachments in the sx170 porting thread.

edit:
dng_validate (from the Adobe DNG SDK) shows the following for your DNG head:
*** Error: CFAPattern does not contain all the colors in the CFAPlaneColor tag (SubIFD 1) ***

About the DNG: I just read the DNG2PS documentation, I will calibrate the camera this week and try again.

I will read about the debug patches, I think I understood the big idea :-)

Thanks for the help as always!

Edit: With the current raw hook (not in dvlptask), using dng4ps's calibrate crashes the program.

Back with the debug patchs:

Unfortunately the camera logs show it's not quite the same as sx170, as the dvlp task does not get hit with the correct args.

(capt indexes are a little bit different, in ixus160 what is called capt 4 is capt 3 in sx170 and capt3 was not in sx170, sorry about that)

So looking at dvlp lines, there is no "dvlp q1 3 x x, x" so the ""    BEQ     loc_FF99BD38 \n"  //  1st msg after shoot" never gets hit.

Successfully tested with putting the debug func at "loc_FF99BD44:\n", I can increment the value.

There is also no SS Raw event, but I don't know if it's just the camera.

(didn't implement the fwt log hooks)
We can also see that the capt 2 call is actually earlier than the dvlp call, so no point if I understood right to put it in dvlpseqtask.

Edit: With the current raw hook (not in dvlptask), using dng4ps's calibrate crashes the program.
Wwait... Isn't this using a simple RAW file? Did you create a camera profile for your camera? (If you did create one that lets you convert RAWs to usable DNGs, it might be that your 20MP pictures exceed some internal limit and cause the program to crash.)

0.2.3 branch does not have calibration features, only the 0.2.2 has (unless there is another build than the google code one)

It does use a RAW file (not DNG), but if I understood right, from the JPG and RAW file (and a picture of a calibration pattern) I can generate a camera profile.
