managed to get a GCC 3.4.6 compiled trunk 620 for A590-101B to run metronome without crashing by
setting PostLEDMessage in stubs_entry_2.S to an empty function:

NSTUB(PostLEDMessage, 0xFFC00948)

evidently the small differences in produced code by GCC 3 and 4 were responsable for
the autobuild version to 'get away' with the wrong address, while GCC 3.4.6 version
choked on it ...

Whim,
Many thanks for your advice. When I ran cardtricks in Winwdows 20000, it worked a dream.
I now have a fully fuctioning camera! All I have to do now, is to learn about the programming language and work out what it all means. I would like to get the date (in different forms) on the screen as well as the time.
I am very impressed.

I'm intrigued to know how it was found out that the cameras could be programmed like this.

Thank you again.
Pagnol.

Hi all, I've just loaded 1.01b-0.8.9-623 and found that AV bracketing works only in - mode when set to +/-

Are you sure you aren't starting at widest aperture available for given zoom, because you can't go wider than that?

Has anyone found or made an external/AC power supply for the A590 (or one of the other cameras that uses 2 AA batteries)?

quick question though: why do the 590's have  "stub_entry" and "stubs_entry" stuff ?

(in platform/a590, trunk 618 src, note the dropped 's')

not a typo I hope ?

The whole thing is a mess. Those do not appear to used.

The stubs_entry.S cannot be generated from the existing sig files, and contains a whole lot of stuff that isn't used. The stubs_entry_2.S also contains a whole lot of garbage (unknown_libname_80 ... WTF?), including stuff that is correctly found in stubs_entry.S... along with the "THIS IS GENERATE FILE" warning, which it shouldn't be...

Another interesting thing, finsig finds:
Quote
NSTUB(GetDrive_FreeClusters, 0xffc416f0)
NSTUB(GetDrive_TotalClusters, 0xffc416bc)
but stubs_entry_2.s has
Quote
NHSTUB(GetDrive_FreeClusters, 0xffc416bc)
NHSTUB(GetDrive_TotalClusters,   0xffc416f0)
Notice the addresses are reversed. Looking at the a720 dump and addresses, it appears the finsig version is correct.

The 101b stubs_entry.s appears to have been manually edited...

I've cleaned up most of the above, but it's quite possible I've broken something. It's also quite possible/likely that more entry points are wrong.

I've re-directed PostLEDMessage to a RET for the moment.

@karenk
OT, but you can buy them from canon dealers (eg newegg Newegg.com - Canon ACK800 AC Adapter Kit ) at an outrageous price, or get cheap imitations of dubious quality on ebay or your favorite china gadget source.
