eyefi 4gb and chdk

hi there,
I am trying to do the following for a timelapse project.
starting a powershot a710is with chdk on a eyefi-4gb-card to get the pictures (in my homewifi) automatically transfered with the "endless storage feature"to my pc.
my problem:
autotransfer works fine as long as i manually actuate the shutter.
my aim is to use the timelapse-function of chdk.
unfortunately chdk needs fat16 but the 4gb-eyefycard uses fat32.

question: can i anyhow use chdk by starting chdk via the firmeware update from the fat32-eyefi card? cant find the firmware update in the a710is menu...

or can i format the eyefi card while installing chdk with fat16 without loosing the auto upload- endless memory feature of the card?

BR,
Tim

Yes

You have to start the camera in "Playback" mode by pressing the PLAY button - not the On/Off button.  Then press MENU and scroll down to the bottom of the menu that opens.  It should be there.

Lots of discussion about that a few years back.  I don't recall if it was resolved.

big thnx for the fast reply!
I really didn't find the firmware update in the menu- shame on me!

The reason for trying all this is, that I have a bird nest right in front of my window - the eggs are already there- so I need to hurry up to set up the camera.
I want to do a long timelapse for about 5 weeks.
I want to set up a webpage where I upload the newest taken pictures automatically.
That is the reason for using the Wificard, BUT it would be great not to completely restart chdk after powerloss. In addition to that the camera is in a very unaccessible position.
So the best would still be to autostart chdk.
could you provide me any help for that?

BR,
Tim

Well, your A710 was released back in 2007 so the largest card it can use with a single partition is 4G.   (Getting CHDK to work on a dual partition eye-fi card seems to be tricky. But reading through old threads on this forum it appears other have done it.)

You should be able to use STICK to configure your eye-fi card so that it will autoboot.   That way CHDK loads automatically each time the camera starts if you put the SD Card lock switch into the locked position.   If you are using an intervalometer script,  you can have that start automatically too via the Autostart menu option in the Script menu.   Finally, some people use a mechanical clamp on the power button so that the camera starts automatically when power is applied.

HTH.

Hi there,
the Webste is running and I grab the pictures from the wifi card.
To be honest, I recently discovered the exe-fi-settings in chdk. i used the normal chdk-features to transfer the pictures to the pc. what is the advantage when using the eye-fi feature from chdk?

Right now I am using the 4gb original eye-fi card with chdk on it- the standard partition is a fat32- so it is impossible to boot from a fat32-partition or am I wrong?
Would be really to cool to use the autostart AND being able to either remote delete the pictures or to activate the buildin endless storage feature.

www.knastamsel.de is the project I need your help for!

You can boot from a FAT32 partition with any CHDK compatible camera released after Jan 1 2011.   As I mentioned,  your A710 is several years older than that.   

You should be able to reformat (low level) a  4G card as FAT16.   But I'm not certain what that does to any files the eye-fi part of the card needs or if the eye-fi card cares.    There was a lot of discussion about this on the forum a couple of years ago if you want to try searching for it.

Still having some trouble in using the endless-memory-feature.
I had the idea to simply integrate the deleting in the sevenup-script i use.
Sadly I am not the programming guy, so the idea is to delete the last (or all) pictures right before taking a picture.
The intervall is 2 minutes.
Is it possible to tell the script every 2 minutes to first delete all files and then take a picture and wait again 2 minutes? that period of time should be enough to let the eyefi-card upload the last taken picture...

Might be overkill for this application, but this can be done with event procedures:
call_event_proc("RegisterProductTestEvent") -- this has to be done only once prior to calling PT_EraseAllFile
call_event_proc("PT_EraseAllFile",0) -- this one erases all files known to the firmware (photos, videos, unless they're protected)

Tried this on an ixus65, should also work on the a710. I have mentioned PT_EraseAllFile previously here (for reference). PT_EraseAllFile did not seem to lock up the ixus65 in playback mode.

hey srsa,
to bee honest, I still  do not know how to manage that.

trying 5 hours to make the eyefi-card bootable via fat16 to solve at least one of my probs.

the result is that I get an error "fehler: module nicht verfügbar".
totally frustrated I go to sleep. :-((
any ideas out there?
is this a eye-fi-problem?
tried the same files on a normal 1gb-sdcard and everything works fine.

This probably means that CHDK was not able to load the files in CHDK/MODULES

If you made a multi-partition card, then it's likely they are on the wrong partition. Otherwise, maybe they aren't on the card at all, or something is wrong with the filesystem on the card.
Don't forget what the H stands for.
