Then you have another option in the debug menu, which calls the FW function "GetLogToFile",
and this will do the job and creates a file in the root of your SD-Card with the assert/exception information of the last crash.
You can also do this with the eventproc interface and a lua script, no patch needed. You probably need to call "System.Create" or "SystemEventInit" first.

I was going to merge the GetLogToFile patch, but I couldn't get it to work under vxworks, so I couldn't test it.

You can also read the log directly from ROM, seems to always be at FFFFE000 on the cameras that I've looked at. Some decoding would be required.

Cool. I think it would be very helpfull (for bugreports and also in generell for development), if its possible to get the ErrorLog via a script on every dryos camera without need of patching CHDK.

The port is almost finished, but during my test i found three things that are not working as expected:

1) If CHDK is used to put in the ND-Filter, the ND-Filter snaps in (good), but after 2-3 Seconds the camera throws an assert.
    If i put in the ND-Filter via the original canon menu, and then via CHDK no assert happens, maybe they have now a check in the
    code to verify (hw via. sw) state of the ND-Filter. So i currently disabled the HAS_NDFILTER option in camera.h for my port.

2) The lua testscript almost works, but there is one FAIL entry left. The "Remove" command is not able to remove the "A/MDTST0" directory. Removing files in the directory is working fine.

3) The Zebramode looks strange. With the standard zebra-osd-code, i got the screen half filled with strange pixel fragments. So i add the g11 to the define checks in gui_osd.c (#if defined (CAMERA_sx200is) || defined (CAMERA_g11)). So the sx200is code is used know, because of the same framebuffer & resolution layout. This looks a lot better, but not perfect. The zebra drawing does not match the overexposed areas, it is allways drawn under it.  :blink:

Can you post an image showing a simple shape, such as a lightshade or overexposed computer monitor ?

The position in the buffer of a pixel at x,y is  :-

sy=y*screen_buffer_width;
s=sy+x*2;

because every x pixel is drawn twice (or four times for multichannel).

If the zebra is drawn too low but correctly positioned horizontally, the value for screen_buffer width must be too big.

Okay, here is one example picture, the zebra drawing is to low and also streched.
Horizontally positioning looks ok, i think.

Currently, i use this size:
long vid_get_bitmap_buffer_width() { return 960; }

As may you can see, also a green distortion line on the top of the display often occurs with activated zebra drawing.

viewport_width = vid_get_viewport_width();

What width are you using for the live viewport ?

It is normally 360 but maybe it is 480 with the G11 ?

(I cannot remember if you have tested other features that require a correct value for viewport width, such as edge outline and motion detection).
