Hello,I recently installed build a3000-100d-0.9.9-1425 on my A3000. I'm unable to open DNG files produced with this version using ACR or Lightroom. I get a generic "don't support this camera" error. I downloaded and managed to build the dng_validate executable from the Adobe DNG SDK. This utility informs me that the DefaultCropOrigin is invalid.I haven't yet built CHDK, but from inspection I think I see a problem. In chdk/platform/a3000/platform_camera.h there are the defines:#define CAM_JPEG_WIDTH 3648#define CAM_JPEG_HEIGHT 2736#define CAM_ACTIVE_AREA_X1 8 #define CAM_ACTIVE_AREA_Y1 8 #define CAM_ACTIVE_AREA_X2 3616#define CAM_ACTIVE_AREA_Y2 2736These are used in dng.h to construct the crop origin:#define CAM_DEFAULT_CROP_ORIGIN_W ((CAM_ACTIVE_AREA_X2-CAM_ACTIVE_AREA_X1-CAM_JPEG_WIDTH )/2)#define CAM_DEFAULT_CROP_ORIGIN_H ((CAM_ACTIVE_AREA_Y2-CAM_ACTIVE_AREA_Y1-CAM_JPEG_HEIGHT)/2)The JPEG width is larger than Active area X2-X1 (and Y2-Y1), so this computation underflows and returns 0xffffffec and 0xfffffffc for the crop origin width and height.I don't know how to determine the active area numbers. I made a guess at sensor size of 3720x2772 for dng4ps2, but don't know if those are correct or how to derive the active area.Regards,Greg
The usable area seems to be:X1 = 0Y1 = 0X2 = 3700Y2 = 2772That is there are 20 pixels on the right edge that are black or garbage. The left edge looks clean and full height is also clean. I could be convinced that the last pixel or two on the right edge are a little dodgy even at 3700, but then there are plenty to be clipped to get down to 3648x2736.
Hi there. i am using the 1.00c version. 1st, i tried download from SVN server. Not working. after pressed "update" the screen turn off and nothing happened. then i tried all version, same, nothing work. Finally i decided the 1st release which ERR99 post on February. ERR99, can u make update for 1.00c?also, sorry for my lame question, can i make this chdk auto boot in my camera?
@reyalp, let me make sure I follow. Are you asking me to replace the files in the two partitions of my SD card with the ones attached in your zip file?
@reyalp, I used Stick 'manual' procedure to install your attached build, but the camera doesn't even power ON when I install your test image in the SD card.
