I was not aware, but Canon seems to have released an official firmware upgrade for this model (1.1.0). In April, this year  :o

Please make a firmware dump and upload it to a file sharing site.

Hi! thank you for the quick reply,
I'm a beginner, how do I make a firmware dump?

You'll need to set up a card like it's described here: https://chdk.fandom.com/wiki/Canon_Basic/Card_Setup
When done, get one of the first scripts from this page: https://chdk.fandom.com/wiki/Canon_Basic/Scripts/Dumper and copy it to a file named extend.m
The first page also explains how to start the script on the camera.

Hi! I tried EOScard but it doesn't seem to work, I can't see any modification applied to the SD card
I also don't know how to run a lua script.
Thank you!

Wait a minute.

EDIT: Judging by the stubs_entry.S file, it looks the same as the 100c version.
Have you tried running CHDK for cameras with 100c firmware?

Most parts of the firmware indeed look identical - the officially mentioned change seems to be the only one:
Quote
Firmware Version 1.1.0.0 incorporates the following enhancement:

1. Support for the "image.canon" cloud platform has been added.
But, the 100c build will fail the compatibility test and refuse to run on 110a.
I'll add support for 110a in a few hours.

Yes, and firmware_crc will probably be different. :(
