EDIT: Do you think it's a good idea to creat a topic at DryOs Development?

Yes, excellent idea, I just did. :P

So, this is my status for the day. I'm looking at a470 for reference, and I could almost finish boot.c.

Good job! We should somehow coordinate our work, I created a git repository at github so I could mirror everyone's changes there (I've also started looking at the firmware to locate some functions, but haven't committed anything yet).

Maybe you could drop by on IRC?

However, when I tried to compile a test, it misses some functions, and also, when putting nullsub to this missing functions, it gives lots of errors of linking, like  "undefined reference to `malloc`",  which had his name detected by sigfinder.

I am not yet familiarized with CHDK's build system, my guess is that some .a/.o is missing from the makefile / linker command, or you didn't put the stubs in the right file so the .a/.o doesn't get built in the first place (?), but it's really nothing but a guess.

@fe50: Thanks :)

I had almost no time to do anything - but I think I might get it started a bit.

I am currently setting up environment to try and compile the most simple piece of code and start from there...

I might need help though.
