My first goal is to collect all existing work done to get CHDK working on the SX720. I see asm1989's post where he posted the latest source code but the link no longer works. Does anyone have a backup or has this been committed to the SVN repository? The only commit I see relating to the SX720 is r4572 which improves the signature finder so I am thinking that existing progress has not been committed to the repository.
Welcome :)

It was never added to the official SVN.  The last I have is from April 9, 2016, which is from before it was booting.

I've attached it, but I'd recommend waiting to see if @asm1989 or @srsa_4c has something more current before digging in.

Digic 6 support has matured quite a bit since, so in any case you'll want to refer to the other ports that are in SVN.
Don't forget what the H stands for.

I agree with you regarding waiting. I don't want to duplicate any existing efforts.

I don't. asm1989 has not logged in for 3+ years.
I seem to recall that the CreateTask patch has unusual alignment requirements in this cam.

srsa_4c, I understand the desire to get started right away however reviewing the thread asm1989 has made signification progress  and it looks like he was working on it for over a month. I don't want to lose out on that. Any time invested in contacting asm1989 to get the files will be well worth it. I already sent him a PM. I am not sure if he gets an email notification for that but if he does he may see it and upload what he has.

The task hook issue srsa_4c mentioned is here https://chdk.setepontos.com/index.php?topic=12804.msg127880#msg127880

As I mentioned, digic 6 support is a lot more mature than it was when the original port was started, so if you don't hear from asm1989, starting fresh shouldn't be a really huge deal.
