and 640 x 480 seems to be ok for this cam too?

Do you think is something related to the resolution?

maybe the #define CAM_SCREEN_WIDTH                    720  at  camera.h   > Tried with 640 too with the same result

Yes, the framebuffers (in your ram dump) are all configured to 640x480.

Code: [Select]
    #undef  CAM_BITMAP_WIDTH
    #undef  CAM_BITMAP_HEIGHT
    #undef  CAM_SCREEN_WIDTH
    #undef  CAM_SCREEN_HEIGHT
    #define CAM_BITMAP_WIDTH                    640
    #define CAM_BITMAP_HEIGHT                   480
    #define CAM_SCREEN_WIDTH                    640
    #define CAM_SCREEN_HEIGHT                   480

That means, the LDR instruction copied to the unaligned address will load a different value and not what we expect.
Ugh, good catch. I guess I can make finsig_thumb2 output the appropriate patch code in the comments depending on how the original CreateTask is aligned.

There isn't really a palette on d6 cams, so the same setup that works on sx280 and g7x should probably work.

That looks like dimensions to me. Did you adjust the dimensions to 640x480 as srsa_4c said?

Since no palette is used on these cams, the stuff there is basically dummy values to keep the CHDK code that expects a palette happy. It should not be camera dependent.

Similar thing happened here, scroll down for the solution (make clean).

Keyboard seems to work, wifi and menu open the respective canon menus,  but there is no keyboard override so maybe is better to start fixing why initfilemodules and captseq
