Clean Canon overlays (G7X II, G5X; EOS M10, M3, also M5, M6, M100 via script)

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?

1. Why not define CAM_CLEAN_OVERLAY in all D6 cameras?

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.

2. Otherwise, how do I determine if a camera is a D6 one?

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.

3. I understand that g7x2 is the only D7 one. Did anyone bother looking for its palette_buffer_ptr?

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.

Hi, this is my first time using any of this. I'm desperate to get clean HDMI, but I cannot figure this out for the life of me. I loaded CHIMP onto my SD card and got the CHDK working(I can access the menus and such), but I can't find the setting required. Any help for noob?

Which camera is that? This CHDK feature is only available on the EOS M3 and M10, a short description can be found on card, in the file named camnotes.txt.
The other models mentioned in the thread title (plus now the G5X, hopefully) are supported through a simple script that is unrelated to CHDK. If you installed the script on one of those cameras, all you need to do is start the cam in playback mode and press SET.

Sorry, this is for the G5X! But yeah, I managed to install CHDK (do I not need to?) I can't figure out how to run scripts/find the script I need to run. I can get to the script page in the menu, but the one that I'm supposed to run "clean overlay" doesn't appear to be there. Am I completely missing something? Thanks so much for anyone who helps!

Try updating to the latest development version.

If that doesn't work:
1. Delete CHDK from card.
2. Run CHIMP BETA 5X and select Disable Autoboot.
3. Run CHIMP BETA 5X and select Clear Canon Overlays.
4. Follow the instructions on the Summary page.

YOOOO!!! Thanks! I just had to update to the newest build I guess! This is great! Now I just need to get it to stop powering off, haha. Trying to use it as a webcam for streaming! Maybe I need a dummy battery. Thanks for your help!

srsa_4c

FlackBlagNow I just need to get it to stop powering off

In CHDK menu:
[tt]CHDK Settings -> Disable LCD Off [Always][/tt]

To get rid of the CHDK overlay, you need to set
[tt]CHDK Settings -> OSD Settings -> Show OSD [ ][/tt]
and (in case you're recording video on cam)
[tt]Video Parameters -> Show remaining videotime [Don't][/tt]

You guys are the best! Saved me having to brave Craigslist! Many thanks and cheers!

Hello there,

I've been searching for a way to have a clean overlay on my Canon EOS M6 that has 1.00F Frimware.

Is there anyway to have clean overlay and infinite LCD on, on my camera?
