So it's not all cameras with palette_buffer_ptr, but more than those with CAM_CLEAN_OVERLAY.

1. Why not define CAM_CLEAN_OVERLAY in all D6 cameras?
2. Otherwise, how do I determine if a camera is a D6 one?
3. I understand that g7x2 is the only D7 one. Did anyone bother looking for its palette_buffer_ptr?

Most D6 cams do not output HDMI signal while in rec mode. Cleaning analog output makes very little sense.
Plus, CAM_CLEAN_OVERLAY requires someone finding the required addresses (manually) and someone checking the result on an actual camera.

It's probably best to look for ROMBASEADDR being defined 0xfc000000. platform/camera/makefile.inc or platform/camera/sub/fw/makefile.inc
If it's ported, that is. But, you also need to look up the camera's documentation for clues about HDMI output.

As soon as someone comes here, asks for this feature and is willing to test on their g7x2.

That leaves out D7, which has 0xe0000000. I think I found a better way - check for THUMB_FW. That produces a nice list of D6 and D7 cameras as in the screenshot.

However, intersecting those with the ones that have palette_buffer_ptr leaves us back at square one (M3 and M10).

Here's the latest build featuring a new revision display format (see screenshot).

Edit: Binary removed; see below.

Sorry - I've not really followed the purpose for all of this.  Once CHIMP determines a camera or firmware version is not supported, does it give you the option to install a test build?

No, test builds are an entirely separate scenario. The supported version list is for informational purposes (so the user may upgrade/downgrade to a supported version). The supported model list is there simply because it's easy to implement once a list of supported items is in place.

Now, I didn't forget about your request. The way CHIMP is designed doesn't make that an easy task, to say the least. I did make some progress in the 'platforms' branch. Now, adding the script installation feature ('overlays' branch) actually helped me make a better sense of the mess I made two years ago, so hopefully this isn't a completely wasted effort :)

Updated build with some fixes:

  • Generate script.req
  • Handle exFAT-formatted cards
  • Handle switched partitions

It also has the nice bonus of actually working when extracted into an empty directory.

Hi everybody

Thanks to this forum I'm able get clean HDMI from my m100.

Another problem I have is that M100 powers off the led screen when HMDI is plugged in.
Is there a work around with CHDK/Canonbasics to keep led screen on when HDMI is plugged in?

Thanks

No known workaround for that, sorry.

Thanks for your reply.  Maybe in the future...
