@dabbeljuh
thanks for the feedbacks! i have noticed an occasional menu refresh problem on my cam too (in my situation the menu just vanishes).  for my cam it is quite a rare problem and right now i have not been able to reproduce this problem systematically.
This is normal for all versions of CHDK, when canon updates the screen, the CHDK OSD gets wiped out. See sig ;)

mweerden did some work to work around this on the ixus870, see changeset 769 / mantis issue 260

Okay, finally  :) I found some problems (don't know whether they aren't implemented yet or just bugs):

-When I activate the "battery-termperature"-option of the OSD and change to RecordMode, the screen turns black after ~0.5s and the cam seems to shut down (objective stays open)
same when I activate the option already in RecordMode
After that, the cam could be restarted as normal

-"Save Edge-Overlay" doesn't work

@reyalp
thanks so much for the great help. will make the changes later today, test and the update the diff file as soon as possible
Thinking about this a bit more, it's probably easier for me to check in what I have now, and then you can post patches against that. I'll try to get that done today.

Sounds like the entry point is wrong, or not implemented in canons firmware (istr SX110 had the same issue)

Ok that's fine for me, do it when you have time. Meanwhile I think I've fixed the issues you pointed out.

In the keymap[] I had to swap KEY_MENU and KEY_DISPLAY values to map correctly the buttons (before that CHDK menu was activated by the DISPLAY button and not by the MENU button)

I still have to fix the aperture_sizes_table (my table is certainly wrong)

I still have to understand if the camera has ND filter or not....I think camera has ND filter, I deduce that from the fact that I did few test shots overriding the aperture value and DOF looks always the same, and...I cannot seen any diaphram closing.

But I cannot find the related functions inside the firmware. I can locate the "magic" strings "TurnOnNdFilter" "TurnOffNdFilter" in the dump, but IDA is not able to find any reference to those strings...So I need more time to fix this

@dabbeljuh

thanks for your testing. I am going to try to fix at least the edge overlay problem

OK, I've checked this in, svn 797

It's mostly unchanged from what you sent me, but I did correct CAM_UNCACHED_BIT

Also a note on lib.c, hook_raw* are obsolete and not needed.

I got a problem compiling it.
Is it possible that the Makefile is missing in the a2000-loader?

@dabbeljuh

that's right, i got it to compile by copying:
Quote
loader/a720/Makefile -> loader/a2000/Makefile
loader/a720/resetcode/Makefile -> loader/a2000/resetcode/Makefile
... creating:
Quote
platform/a2000/notes.txt
... and adding an a2000 entry in the root Makefile in the
'batch-zip:' 'batch-zip-complete:' and 'batch-clean:' sections
got only 1 warning:
Quote
lib.c: In function 'hook_raw_fptr':
lib.c:50: warning: return makes pointer from integer without a cast
which seems to reflect reyalp's remark

have fun testing/playing,
wim

@reyalp

do you ever sleep ? :D

cheers,
wim

edit: still misses notes.txt though (and maybe commented-out root Makefile entries) :
Quote
lib.c: In function 'hook_raw_fptr':
lib.c:50: warning: return makes pointer from integer without a cast
cat: ./platform/a2000/notes.txt: No such file or directory
@dabbeljuh
remove warning by adding "(void *)" before "0xEC04F0" in platform/sub/100c/lib.c
and CHDK-Shell will give you the 'green light'

Would be cool for CHDK-Shell compiling

Thanks a lot for all your work

Edit: I know I could do it by adding the a2000-lines to the root-Bootfile, but I'm just tired of doing it with every new build  :D
Sorry, I'm a bit lazy today  ;)
