This is the diff output comparison of stubs_entry.S of sx240hs (100c) and sx260hs (100c)

Code: [Select]

$ diff platform/sx240hs/sub/100c/stubs_entry.S ../chdk.sx260hs/platform/sx260hs/sub/100c/stubs_entry.S 
7c7
< //   Canon PowerShot SX240 HS
---
> //   Canon PowerShot SX260 HS
11c11
< //   PLATFORMID = 12869 (0x3245) // Found @ 0xfff40040
---
> //   PLATFORMID = 12868 (0x3244) // Found @ 0xfff40040
113c113
< NSTUB(ExecuteEventProcedure                   ,0xff07c400) //  2
---
> NSTUB(ExecuteEventProcedure                   ,0xff07c400) //  1

That make me think that this port could be done as adding support for a new firmware version of sx260. Maybe in a few weeks I could try a blind port

Great news.
I am here to support you with anyway.
What's the difference between the version 100a and 100c?
Can I update my camera with the 100c?
Thanks

You are correct - version 1.00a. Attached a photo from the ACID check.

This is very interesting, I don't think Canon has ever done it this way before. There have been a few cases where different model names (e.g. IXUS 80 and IXUS 82) but were identical, but they also have the same PID.

Don't forget what the H stands for.

i too bought the sx240hs a month ago. i've successfully installed&used chdk for years on my previous a590is camera, and was eager to see how chdk works on sx240hs (if available). sad to find out that it's not as yet, but as i see plans for it are ongoing.
looking forward for good news regarding implementation of chdk on sx240hs, and thanks a bunch to all those involved in this great work!
