Here's a test build for g7x firmware 100b. This is completely untested. See the "G7 X notes" section of the included readme and the 100d post https://chdk.setepontos.com/index.php?topic=12692.msg127047#msg127047 for other information about the G7X port

I strongly recommend using the bootable SD card method to load CHDK for actual shooting, as the "Update firmware" method does not appear to initialize some hardware correctly.

Using the "Update firmware" to load CHDK and make FAT 32 formatted card bootable seems to be OK.

Thank you very much, reyalp. That is really cool news  :)
There were no problems, getting it to run on the camera.
I ran a couple of sequences with rawopint on my G7X, and it seems to work fine. The exposure is correctly following the ambient, and shutterspeed/ISO adjustment works out nicely. I had it maxed out at 3200 ISO for the test, to see if if there were any issues (as my G1X has), but I didnt notice any.
There might be an issue with setting the hyperfocal distance through pressing down when the OSD is up. The camera totally misses focus. Pressing up for infinity, seems to work, though. This is with the camera set to manual focus.
Thanks again, its such a thrill to have CHDK up and running on the G7X  8)

Thanks for testing and reporting.

I haven't tried this, I'll try to take a look at some point.

FWIW, on my G7X, maxing out the MF distance does not give good infinity focus, the best focus seems to be about 1 step below full on the MF bar. This is very noticeable for astrophotography.

Also the bar being full isn't the last step, the focus continues changing (getting more out of focus) for many clicks after the bar is full.
Don't forget what the H stands for.

The 100b version works without further quirks so far.
One great thing that I found (I guess this must be known, but it is new for me). In the raw (dng) shooting mode the g7x produces a dng even under remote control by Android phone app. This is the only known to me way of coercing the g7x to  produce raw in the remote mode. Now if only it could do touch focus from the phone...

Good to know, I haven't actually used the phone app at all.

Not likely to be possible without hacking the phone side, at the very least.

That does give me a related idea though: It should be possible for CHDK to simulate touch events, allowing mouse (or touch) actions on the chdkptp live view to be used to control the camera. Hmm.

The phone app contains extra options that depend on the camera, in particular those that are not implemented for g7x. The touch focus on the phone works for 70d. If there is a chance that the camera reports its options to the app, then likely no app hacking would be needed...

Yes the phone app is nice, but limited on the sx60 too.  I think it allows control of zoom and movie record as well as shooting in what ever mode you have setup.   I never bothered to observe whether raw was created because Canon hides the raw from you until you collect it using their software or you look for it on the card with something other than canon interface. 
I recall it's possible to specify an IP address when using chdkptp...not sure if that's useful.  Perhaps chdkptp runs on android phones?

chdkptp has not been ported to android.

chdkptp does have code to support PTP/IP but I was never able to make it work in record mode, and setting up the connection is tricky. Canon uses PTP/IP for wifi file transfer to PCs, but I believe the phone apps use a different protocol.

Results from my investigation of the wireless stuff is in https://chdk.setepontos.com/index.php?topic=10724.0

" With the Camera Connect App, you can use your mobile device to shoot remotely with your Canon camera. Compose your shot, set the zoom, focus, self-timer and more, then release the shutter all from your smartphone or tablet. The photos and videos will be saved on the camera"
This is all nice, but in practice what you can do using the app depends on the camera. With g7x only zoom and shoot are possible. Independently of the settings/mode on the camera the remote shooting is in a dumb auto mode with the camera deciding what it focuses on in the frame. Canon advises to "make test shots to check the focusing". With the 70d I can set the aperture, shutter speed, focus point --- much like in that ad for the camera connect ad. Also the 70d records raw if it has been set for that initially.

Also, when mentioning raw I do not mean transferring the raw file to the phone, but rather recording and keeping it on the card. With chdk this is the case with the dng format. Certainly, no lens corrections are done in the dng, but that is not a big deal in post processing (which is the whole idea for raw anyway).

As to the type of wifi connection I mean adhoc direct connection (not through the router). This is what may be useful in the field, where an infrastructure network is not likely available.
