The timestamp in the log file is from 2014:08:13 07:01:47 = five days ago.  Is the time set correctly on your camera and if so, is that when you saw the last crash?

I checked it once more, timestamp is exactly where I saw that chdk was not loading for the first time. Time Setting in camera is correct.

The attached file is new logged at 19:15 local time also set in camera, timestamp in file is the same as in my first file before (2014:08:13 07:01:47)...

Waiting for Your new build as announced...

Regards, Andreas.

Can we enable DNG support on the N FB next? If that worked it would be useful to me...

Quick and dirty next step.  Turned on the capt_seq.c tasks and the touch task.   Adjusted the screen colors a bit to compensate for the custom palette still not working.

If it all works you should have a functional CHDK (minus the video function and FWT stuff).

Thank you very much. I booted it and it worked. Setting CHDK up didn't work well as the camera touch still isn't disabled and kept getting in the way with the arrow buttons so I simply took an already set up CHDK from another camera and copied the N FB one over it. I then had the options I wanted.

Shooting DNG I found two problems.

1) The DNG files are broken. dng_validate reports:
*** Error: Invalid DefaultCropOrigin ***

2) When quickly pressing the shutter (without waiting for auto focus) no DNG gets written.

Can you open and look at the image?  It's probably the same parameters that will need to be changed for the N but I can open the DNG's it produces.

The DNG cannot be opened by PS or by the latest DNG converter (converting into another form of DNG). It can be opened by dcraw however. So Adobe products reject it.

This was one of the tests nafraf requested me to perform on every camera model of the 30 in the ETR thread. So I did there and so I did here...

Did the image & colors look correct with DCRAW ?  If so the it should just be a simple header change.

The hook location that I believe affects this is one I found by looking at a couple of other ports.   So they likely have this problem too.   I'll dig a little deeper.

Code: [Select]
// try avoid intermittetant override failues on quick press, not needed?
//"    MOV     R0, #0\n"                          // added
//"    STR     R0, [R5,#0x28]\n"                  // added
"    LDR     R0, [R4, #0x28] \n"But replace R5 by R4.  ::)
