G10 Porting Process

[Shinigami]

well, I have to commit for you to work on it too, but I don't know yet if I can just commit the source or have to ask someone first... as soon as I find this out I'll commit, but if you want I can send the modified source to your email right away, it's only 2.3MB zipped

[simonbh]

No, I'm not Brazilian.

I would like to see your modified source.  Please email it to me.

Thanks!

well, I have to commit for you to work on it too, but I don't know yet if I can just commit the source or have to ask someone first...

You do not have write access to the SVN server.
Typically a CHDK developer commits a port when a stable beta version is available.
To get code into the CHDK trunk, post a diff file here in the forum when the time has come...

[reyalp]

If several people want to collaborate, you can always sset up your own svn or git somewhere (a space on assembla where CHDK is hosted, for example)

Or you can exchange patches against the current source.

[Shinigami]

I think I'll revive my deceased linux server... As currently I'm the only developer active, it won't be much of a problem if this takes some days.

[Shinigami]

Well, people... As I didn't had my G10 at hand yesterday, I just worked on stubs_entry_2.S, so there's some addresses in it. Today I tried and retried to make the leds blink in loader/g10/main.c without success. The camera hangs up before anything happens and only cames back after the battery is removed. So I'll go back to start and check everything again.

Good work so far!

[Shinigami]

Here I am again. Now I'll post the stubs for your enjoyment ! Anyone who wants to work on it just send me the package name you'll be working on. Go on, guys, grab yours while it's hot ! IT'S FREE !!! (not pain free, of course)
Let's not put too much messages in this thread, all messages shall be sent privately to me (requests and results) and I'll update this post accordingly.

Code: [Select]

/*! @file stubs_entry_2.S
 * This file has corrected firmware function addresses
 * In this file you have to put all the firmware function addresses
 * that the build system can't get just right.
 * @author Shinigami
 *
 * @note
 * Using pointer to BX LR (just look for nullsub in IDA's function names list) as reyalp suggested
 * I've separated unknown stubs in packages as Microfunguy suggested
 *
 * @warning all these addresses have to be checked

Just wanted to say that I'm really excited that someone has committed to porting the G10. Shinigami, I'm useless when it comes to programming, etc., but If there's anything I can do to help, I'll try.

[Boobo-oobo]

Hello, another G10 user that needs this "mod" should I say. Shinigami, how close are you to finishing this? I found about this today, and I'm very interested in this. Please contact me, I'm willing to help in any way i can.

[Shinigami]

Ok, people, here we go. Sorry for the delay, I had some personal problems. Anyway, the SVN server is ready, you may anonymously access it at svn://shinigami.sytes.net/svn/repos/chdk_g10_103b . It's the complete CHDK source revision 885 with the G10 support added. If you want to help the develop process, please send me a private message. Make sure you know how to work with SVN (http://svnbook.red-bean.com) and that you've read all the CHDK developing and porting docs and followed all instructions before messaging me.

Oh, and take it easy on the server, it's only an old notebook using my home's bandwidth, don't expect much out of it.

About the progress, still locked trying to boot. I still have some things to do before I can go back to development.

[Shinigami]

Now the G10 has it's own trac ! Here you can see it. No login or registration yet, so no tickets. I'll do that latter.

[lightfusegetaway]

Thank you for your work! I think some of us G10 owners were starting to feel neglected.

I don't have any programming experience but will beta test the heck out of it.

[testicon]

Hi everyone. I would love to help out with G10 development as much as I can. Heres what I can offer:
obviously i own a g10 and love it to pieces.
I currently have a linux server that while not amazing, is hooked up to a 20mbit fiber optic connection, and honestly, ive been trying to find something worthwile to do with it besides having a super easy/fast way to access my files from work.
I am currently studying computer engineering, so this should be right up my alley.

[penguinischicken]

Thank you for your work! I think some of us G10 owners were starting to feel neglected.

I don't have any programming experience but will beta test the heck out of it.

I can't code either but will participate in testing.
