I have FINISHHH my port!  :D :D :D

http://www.zshare.net/download/640141362c95c5/

...but don't run  :o

I don't know why, i have complete boot.c, I have found all missing function and insert them in stubs_entry_2.S...

...lib.c is incomplete i have found 3 address:

Quote
void *vid_get_bitmap_fb()

void *vid_get_viewport_fb()

void *vid_get_viewport_fb_d()

loader is copyed by a560 as a rest of file in platform/a550 (less boot.c, makefile.inc, lib.c, stubs_min.S and stubs_entry_2.S)

BUT DON'T WORK!!!!
when i launch 'firmware update' my camera just switch off...

WHY!?!?

QUESTIONS:

- Is there a 'debug mode' or similar method to find the location of the error?!
- Am I forgetting something...some files??! u
Unfortunately the article Adding support of a new camera is incomplete and I don't know were broken my head  :(

Got a link to the firmware?
Or all the bits in the code that were changed?
Maybe update the wiki page with the new snippet that makes it run now.

and also: Congrats, Nice work!!

First of all a huge congrats and "thank you!!!" for making this wonderful mod possible on A550. CHDK was something I really wanted to have for a long time.

Now what I understand is there is a working version available, right?

I really would like to try it here with my A550 and probably be some kind of help by writing my experience with it.

So if possible do you think you could provide us the files?

Thanks again. Great job.

Hey, what happened to the Wiki page? Everything's been blanked out and the discussion says "Porting process is blocked". Please don't tell me you're giving up! You've been making so much progress!

You said porting process was blocked. Care to post what you've come up with so far? Someone might be able to continue it.

Previous posts indicate a successful firmware, with little problems.

I believe wiki was restored by someone else, not by muttley.

He said:

"NOW CHDK RUN!!  Big Grin Big Grin Big Grin

...the problem was capt_seq.c, nobody say me it's necessary for start...and there isn't doc that say this!

THANK ROSSIG, for all support !!

now...another problem: i can't enter in ALT mode...eheheh, is there a function o part of code that i can view for resolve problem? "

I think when he comes back we'll have a somehow working version. :)

Actually, if you view the history of the A550 page, Muttley removed all the info ???
However, one wonderful thing about wikis, is all previous revisions are saved, so you can still get the full info.

I'd use that info and look into capt_seq.c myself, but I don't want to be bothered with compiling gcc for ARM processors.
But perhaps I will anyway...

Jarod (wonder if theres gcc-arm in portage...)

EDIT: wow, that was surprisingly easy to get as far as the capt_seq.c issue, I have a compiled firmware, however my camera has been borrowed (I'll get it back by monday or tuesday), and I have my doubts that it will work without knowing what capt_seq.c does, or what to change in it.

Wow that I've bothered to do this, muttley will release it within minutes of me getting this to work  :lol

(I had exact versions of binutils and gcc hiding in my src dir, handy, but its a way old version of gcc, 3.4.6, I'm using 4.1.2 now)

Any suggestions on capt-seq.c, let me know, if we can get that sorted, I'll compile it, and someone can test it.
