hi,

just to add one more success story: works here very well on a
a530 1.00a (0.4b) - a lot of thanks for this build and keep up the
good work!

one thing i noticed is that the a530 seems to have an nd filter
built in instead of a real aperture - so maybe we can use the
relevant code from the ixus cameras for aperture override (i.e.
only nd filter on/off) ... just an idea

... just noted: at least with 0.4b (which i'm using because
of the compatibility of the files) the jpeg and the raw files
are always offset by one numer - first the raw file and
then the jpeg file with one number higher ... is that
supposed to be normal?

from the very first beta the files counter for jpeg and raw is 'offsetted' (not really offsetted, is simply continous...)
I don't know if even other chdk builds works that way...

just checked the file numbering issue on an ixus 70 and it looks like
this is a bug of the a530 port: on the ixus 70 the files are numbered
correctly (i.e. the jpg and the raw file both have the same number)
- i even remember of having read about the same problem at another
port in the forum, but cannot find it again - maybe asking around
should help to get it fixed ...

hi image13!
i think that changing to

Code: [Select]

long get_file_next_counter() {
    return (get_file_counter()+1);
}

can fix the problem. let us know if this works.

hi,

i took the sources, updated them to the current trunk
and fixed the file numbering bug (files are numbered
properly now) ... for getting it to trunk i had to add
some new functions for which i don't have the proper
addresses yet, so some things might not work with this
version (use it at your own risk) - i'll ask in a separate
thread for help to find these addresses and for inte-
gration into the subversion trunk

i used the 0.4b raw file size for now, because the resulting
rawfiles are more compatible at the moment - this can
be changed later easily

the changes to the current trunk (additional files plus a
diff of two trunk files) and compiled binaries of my
version can be found at

a530.zip - 0.23MB

bondo, can you please have a look at finding the variables
in the dump? (see new thread coming soon for this)

As you request, here's the five addresses:

Code: [Select]

NHSTUB(GetDrive_ClusterSize, 0xFFC5DC88)
NHSTUB(GetDrive_TotalClusters, 0xFFC5DCC4)
NHSTUB(GetDrive_FreeClusters, 0xFFC5DD00)
NHSTUB(WriteSDCard, 0xFFC6D0CC)

and:

Code: [Select]

char *camera_jpeg_count_str(){
     return (char*)0x6E820;
}

Anyways, I think that a530 port is not mature enough to be added into trunk.
Some things needs to be adjusted (i.e. function mode_get in main.c - i tuned it just to work, not really a good job...).
Byeee

maybe also for the main.c issue this post may help?
