Update :  I wrote this simple script and tested it on both my SD940 and G10.  Works perfectly on both cameras so zoom functions are okay and the issues with the vp-systems script are likely SDM related.

Code: [Select]
@title set zoom test
s=0
p=0

print "started ..."
sleep 2000

s=get_zoom_steps
print "zoom steps = ", s
sleep 2000

p=get_zoom
print "zoom position = ", p
sleep 2000

set_zoom_speed 10
print "zoom speed set to 10"
sleep 2000

set_zoom 5
print "zoom to 5"
sleep 2000

end

Unfortunately, not really.  I've started another thread to deal with it :

Once I get the zoom fixed,  I'll look at removing the rest of the SDM specific stuff from that script so that there is a generic CHDK compatible version.

hi Waterwingz, i m another time here to ask you a question, is it possible in any way to toggle the auto audio level during video recording? every time i try to record something with a very loud volume the audio is distorted, so is it possible to have a sort of manual level ? with a script or something?
tnx for all and tnx again for porting chdk for ixus 120

Hi, I've read through the wiki documentation, and it doesnt seem to say anywhere if you can automatically load the chdk when you turn the camera on.

"Not all cameras support dual partitions. Check the wiki page and forum porting thread for your camera before trying to use dual partitions."

How do i know if the ixus120 supports bootable card?

It doesn't say anywhere on the specific camera page whether you can boot from the card automatically, any help greatly appreciated1

Good question.  First of all - it does.   Although as a camera release prior to 2011,  it will only boot from a FAT16 partition  (i.e one 4G or less).  So you will need to use the dual partition scheme if you want to autoboot from a larger card.  More details here : http://chdk.wikia.com/wiki/Prepare_your_SD_card

The note on the wiki page was put there to cover the one or two cameras that do not support either firmware update or autobooting.  Almost all cameras support both - athough cameras released after 2010 usually don't need dual partitions as they can boot from FAT32 so they don't support it.  I guess we should add a standard section to each camera's wiki page stating what configurations work - although that's going to take somebody a long time to complete.

Hi waterwingz, thanks for the quick reply, I have found this page on the Wiki explaining about a program that I can use to create the partitions.

http://chdk.wikia.com/wiki/Using_SDMinste_to_Create_Dual_Partition_SD_cards

I will follow all 31 steps tonight and hopeully get it working! Thanks for your help, A small section on each camera page explaining what methods work would be good. I have just ordered a shiny new SX230, which supports  a more straight forward way of using CHDK on boot by the looks of things :)

Cheers, rich

That page should work for you - those are the instructions I used when I was porting the IXUS120 (check out the page history to see who created it)

I'd still recommend using STICK instead.

Hi waterwingz, I would use STICK, but get this error.....

"Installation failed - see log for details" (but the log says the exact same thing, "...see log for details");

On the forum, this has been written and it applies to me.... looks like the 30 steps are going to be needed!! If the below has been fixed please let me know!

"I apologize to all those who've had problems with ASSIST. The problems seem localised to Windows 7/8 users with cards > 4Gb and pre-2011 cameras (which requires partitioning the card into a small FAT16 and a large FAT32 partition). I only have Windows XP and cannot reproduce the problem myself. Until the problem is fixed, I advise Windows users with pre-2011 camera to stick to cards 4Gb or less.
For UK people with the problem I'm happy to offer a card preparation service - send my your card with a photo on it taken with the camera in question and I'll post it back to you with SDM installed. I'll do this for users outside the UK too, but the two postal trips might take some time."

I proceeded with the SDMinste program and successfully navigated through the steps to the end, and have successfully made it so the camera boots on then loads the firmware. However it says the memory card is full.
What I don't understand, is that the final state of the partitions is that the main partition (FAT16) is only 2mb. It seems like I am half way there. The partitions have been created correctly. But the camera for some reason doesn't want to write to the main FAT32 partition.

Any ideas?
