all my tests with 4 and 16 gig have failed. i've only been able to get a 1 gig card working.

I'm using a 4Gb card on 101a, and the first build worked almost flawlessly...

I'll try at home again with my 4 gig i have different versions of Mac os between home and work.
At work the 4 GIG card isn't recognized by SMDinstaller, but the 16 gig is.
i've tried to make 2 partitions on the card manually, but no luck.
*shrug*

I think i found the problem regarding the 100c build. Please check if with the attached file,
booting from a two partition/SDM-Installer prepared card works.

my Genius 😀

now i can run my 16gb sd card with chdk.

but my german language choice adapted from my g11 chdk pack don`t run .. now i have to wait for the s90 package...EDIT...now its working...had to put the files in the bigger part...my mistake!

Thanks ERR99 for your work again again again 😀

The A570IS has a hardware switch to select play/rec mode. Most newer Canon cameras do this by push-button and therefore are not set in a mode as definite as the old ones. For some reason, they all boot in play mode when CHDK is loaded (except when the power button is held for a few seconds).

If that's true, and ERR99 had a way to get it into Capture mode immediately as before in his first chdk version, can I suggest that we leave the lens-extend on playback, so that the camera powers up to Capture mode immediately? That is a far better alternative it seems to me...

my camera does not turn on with the 100c build. is there a diffrence between 100c and 100a?
excuse the noobness here

amoor

okay so i've tried both my 4 gig and 16 gig cards, and neither one of them work.
SDM installer does not recognize the 16 gig card and has a copy error on the 4 gig

so, i hope i finally was able to get a 101c dump. err99 it would be great if you could tell me if it looks ok, as i'm not really sure.
i'm now working on a mac, prepared a 4gb sdhc card with sdminst (tow partitions), and used your modified udumper.

Yes, 101c dump looks good! It needs only to be cleaned/stripped, to remove the trailing bytes from the empty.dum file.

You have to use the correct diskboot.bin file for you camera firmware.
If you camera hat 101a firmware, you have to use the 101a port. 100c port does not work on cameras with 101a firmware.

great, thanks for having a look. i hope you maybe find some time to try to make a port for the 101c (neither the 100c nor the 101a prots work).

some general (maybe) useful information:
i got the dump with the modified g11 udumper on a 4gb card, i found out that somewhere in the doc the max. capacity of a card for using udumper is 2gb. as my dumping process worked i suppose the limitation is not the card size but the partition size.
as i'm using a mac i prepared the card with sdminst and copied the modified g11 udumper and the empty.dum to the first partition.
that's the reason for the dummy bites left in my dump file.

Okay, here a first try for a 101c port: Test if the attached file boots. If everything is correct, camera should boot without card write protect message.

ERR99

If the above file boots, try also this one. This time also the CHDK Splashscreen should be visible and the CHDK Menu int ALT mode accessable (but no overrivedes will be functional).

mercurio

both work, chdk screen is visible, chdk menu is accesable.

thanks a lot so far, u're great

ERR99

Thats good! 😁
Next steps are to implement the overrides tasks (Exposure, Capture, Movie, etc.).
I will post a build when i finished that for 101c. 😉

@ ERR99,
is 101a complete?

@ ERR99,

It depends of your definition of complete... 😉
From the "Feature view" 101a and 100c have the same state of completion. There are of course some minor problems left (optical zooming in videomode hangs sometimes, set_led for script use is not adapted to the S90, blocking of Jodgdial events to the oem firmware in altmode can be optimized). But most off the stuff other should work. If you find something that not work, post it here.

So, here is the new build for 101c. Please try if its boot and if everything is working. 😉

From an earlier post, regarding the second 101a version:

"A few issues for the 101a build:

The jog dial and control pad buttons are now seemingly unresponsive most of the time, in particular when switching between manual modes. The Menu button usually works first, and that sort of kicks the rest of the buttons into operation, but there are large periods of time when none of the control buttons work, and then all of a sudden the accumulated many actions are sent to the camera and it sort of goes crazy."

I am trying ver. 101a. I have not done extensive testing, but I have noticed that when I boot with my SDHC card locked (but not in alt mode) the front control ring does not work properly when changing aperture or shutter speed. When I unlock the card and boot, these functions work properly. The rear control dial seems to be functioning properly.

I am also trying to use a USB remote shutter release. I have enabled remote in the remote parameters menu and have started a couple of the USB scripts, but without reliable success. Any advice on a script that will work?

The following scripts both triggered the camera occasionally, but not reliably as in the past with an SD870:

@title Remote button
:loop
wait_click 1
is_key k "remote"
if k=1 then shoot
goto "loop"
end

---------------------------------------------

@title Remote button
while 1
wait_click 1
if is_key "remote" then shoot
wend

end

I used a USB remote successfully with the S90 with the first 101a build.

I don't know if this'll help. But I heard that the

while a = 0
a = USB_power
wend

code (or something similar) always works, while "is_key..." doesn't always work, so that's what I used. I didn't try the is_key "remote" though, but with USB_power it works reliably.

EDIT: oh, and I didn't have to enable the USB remote option for that code to work; in the menu it's still deactivated yet the remote works.

Michael L

Thanks for the quick reply, jblc!

Was that the entire script you ran than worked, or were there other lines?

I ran the following and it froze my camera:

while a = 0
a = USB_power
wend

If there are additional lines I need, can you please post the entire script?

Thanks!

If I get this working, I'll be trying the S90 for some kite aerial photos later this afternoon. If I can't get the USB remote working, I'll probably just use an intervalometer script that is working well.
