Porting CHDK to Powershot SX620 HS - Firmware 100.C

Hello everybody,

I've just received a lot of new SX620 HS. I planned to build a rigid Rig for photogrammetry knowing that I could use CHDK.

One of the camera I've received have 100.B firmware which is working well
All the others have 100.C firmware which don't have the CHDK port actually.

Can somebody help me ?

Thank you very much

Please get a firmware dump using the canon basic dumper https://chdk.fandom.com/wiki/Canon_Basic/Scripts/Dumper, upload it to a file hosting site like dropbox, google drive etc, and post the link here.

We can then check whether this version needs a new port or not.
Don't forget what the H stands for.

Thanks. Looks like 100c will need a new port, but it will be a very easy one, only some ROM data locations have changed. I'll post something in the porting thread https://chdk.setepontos.com/index.php?topic=13426.90 later.
