Welcome to the forum !

No, but a a firmware dump (the first step for a port) is available, see this thread:,4255.0.html



edit: at this stage, you might be interested in finding out if you've got the same firmware version
       as the one from the dump; if that is the case, go here

Don't forget what the H stands for.

I'm working on it - it will take a while because I have to sleep and go to work, too ;) [1]

I have finished yesterday platform/sx120is/sub/100b/stubs_entry_*.S and stubs_min.S files - I had to check circa 105 pointers to functions in sx10, sx110, sx120 and sx200 firmwares ;)

loader/sx120is/ seems to be also finished. Next step is boot.c so stay tuned.


[1] although I sleep and work less because of chdk ;)

I've made a few days break in the porting process -- I had to read a bit more about asm language, passing parameters via stack to subroutines, etc.

Right now chdk loads and keyboard works. Nothing more. I've never done chdk port so I can't tell you how long it will take, sorry.

I'm also interested in the port as well as willing to help in any way I can.  I'm a newbie at CHDK but I'll try to help if you'll share or point me to what you've done so far.
