Where did you found fw200f ?
The latest version I know is 120f.

M3 has no bootflag (excepting "gaonisoy" signature) because there is powershot-like firmware inside it, not EOS.
Sorry, I meant 120f.

By "bootflag", I meant the option in the CHDK menu:
Miscellaneous/SD Card/Make Card Bootable

For 120f try this one. I did not test it on a real camera.

Thanks! It worked, and I was able to "Make Card Bootable."

M3 raw dimensions (was Re: Lapser Script Development)
« Reply #423 on: 08 / September / 2017, 18:28:52 »
I figured out the problem (I think). The JPEG area on the M3 is set to go all the way to the bottom right corner of the active area. My TestRwop.lua script then went a few pixels out of the active area, so I didn't get any meter values.

I'm not sure the JPEG area is accurate on the M3, but I fixed the script so there's no chance of going outside the JPEG area (hopefully). So when you get the chance to test the attached new script on your M3, I'd be interested to hear the results.

Maybe someone can double check the sensor values for the M3? Here's the values I got from platform_camera.h
Code: [Select]
************** G1X ******************
 // Sensor size, DNG image size & cropping
    #define CAM_RAW_ROWPIX                      4496    // Found @0xff190c98
    #define CAM_RAW_ROWS                        3366    // Found @0xff190ca4
    #define CAM_CROP_ORIGIN_X                   28      // Override calculated JPEG Crop position (26)
    #define CAM_JPEG_WIDTH                      4352
    #define CAM_JPEG_HEIGHT                     3264
    #define CAM_ACTIVE_AREA_X1                  80

    #define CAM_ACTIVE_AREA_X2                  4484

Try to use CAM_RAW_ROWS 4059
Canon firmware contains both values, but 4059 doesn't look beautiful...

CAM_RAW_ROWS should reflect the actual number of rows in the raw buffer. Running exiftool should report this as Sensor height. The active area should also be reported.

There is a mismatch:

Exiftool:
Code: [Select]
Sensor Width                    : 6096
Sensor Height                   : 4056
Sensor Left Border              : 84
Sensor Top Border               : 46
Sensor Right Border             : 6083
Sensor Bottom Border            : 4045
Black Mask Left Border          : 0
Black Mask Top Border           : 0
Black Mask Right Border         : 0
Black Mask Bottom Border        : 0
Info from firmware intertnals:
Code: [Select]
DoUnpackedCaptureFordccd RecMode = 104

***AttachdccdImageData Start***

CcdDataSizeH = 6112
CcdDataSizeV = 4059

***AttachdccdImageData End***
some EDMAC channels are configured for 4059 rows, some - for 4060 rows:

Do CHDK DNG render correctly using the 6112 width?

Of course. There is no problem with columns: 6112*14/8 = 10696.

Moved from lapser's script thread: https://chdk.setepontos.com/index.php?topic=13194.msg134620

Looking at this a bit more, I don't think the error lapser saw was due to incorrect definition in CHDK, the script just has to ensure it doesn't go outside the active area.

If you can upload a CHDK DNG somewhere, I can double check.

The vertical size doesn't actually matter too much as long as it includes all the image data, and does not include memory that is used for something else.

The raw size and active area should be even to avoid ambiguity about dealing with half a CFA repetition. This is enforced for active area, but not currently for RAW_ROWS.

The M3 jpeg area is exactly the same as the active area. This will generate warnings in dng_validate because there are no pixels to interpolate at the edges, but seems to work OK in practice (it happens on any port if you change the default crop option to active or sensor.) If there are more valid image pixels outside the current active area, it could be expanded.
