Testing the new Eye-Fi x2 8GB with CHDK on a Canon G11 - wishing for FAT32 boot

I'm working on testing this guy - http://www.amazon.com/Eye-Fi-Explore-Wireless-Memory-EYE-FI-8EX/dp/B003DX3O6I/ref=sr_1_3?ie=UTF8&s=electronics&qid=1273207723&sr=8-3

So far, it doesn't look like using the card with 2 partitions is going to work with wifi, which is pretty much the whole point of the card. Its not a total loss - I can probably use it as a 4GB single partition.

Any ideas on what to try? Any chance I could boot off of FAT32? Any ideas on how I could get 2 partitions to work with photo upload?

Otherwise the card appears to be a great update from previous eye-fi cards.

If anyone here knew a method to boot from FAT32, we'd already be using it. If there were obvious, promising approaches to try, they would have been tried.  So no, there is no chance you could do it with the built in loading methods that exist in the canon firmware.

You could do it if you are willing to modify the on-board flash (be prepared to brick a few cameras in the process), or if you can find some other way to get code to execute (e.g. buffer overflow that overwrites a function pointer.)

Reverse engineer the eyefi firmware :)
Don't forget what the H stands for.

yeah, i figured, but had to ask anyway. thanks

I have been doing a bunch of testing with the new 8GB Eye-Fi card.

You have two options really, because you can not format the card into two partitions and get Eye-Fi to work from the second partition.

First option is to format FAT 32 then copy CHDK onto the card and just using the firmware update method boot CHDK manually.

The second option, which is the one I settled on, is to partition the card to two 4GB partitions, format the first partition as FAT 16 and then load CHDK onto that partition (as well as the Eye-Fi stuff). The second partition is more or less a waste since the camera or CHDK can not access that partition. (If you switch to the second partition using CHDK it will give you an Card Error message)

The benefit to me over the standard 4GB Eye-Fi card was the ability to do Ad-Hoc transfers and handling of RAW data transfers.

You could also buy their older 4GB Pro card and do the same thing, but the older card has to be filed to give the card the ability to fool the camera it has a write protect lock switch.

Furthermore I found that everyone sells the old card for about the same price as the new 8GB card. So whats the difference. The new 8GB card already has the write protect switch. So you can forget the filing of the card.

I guess no matter how you look at it, there is no way to actually use the full 8GB of the card. I faced that reality and moved on just happy I can handle the RAW and Ad-Hoc transfers.

FWIW.

Unfortunately, firmware update boot is not a option on the G11 (E31 / SubCpu error shows up, if you use this boot methode and the camera switches off).


The second option, which is the one I settled on, is to partition the card to two 4GB partitions, format the first partition as FAT 16 and then load CHDK onto that partition (as well as the Eye-Fi stuff). The second partition is more or less a waste since the camera or CHDK can not access that partition. (If you switch to the second partition using CHDK it will give you an Card Error message)


I know this thread hasn't been active for quite a while but figured I'd give it a shot ......

I've recently started using CHDK and just got a Eye-Fi x2 8gb card. Using the method quoted above CHDK works and photos are automatically transferred to my iPhone by the Eye-Fi BUT Eye-Fi helper no longer sees the Eye-Fi card for configuration changes.

Does anyone know how I can get Eye-Fi helper to see the card again? I'm using a Mac.

Thanks,

Tom

Just a note, cameras released in 2011 and later can boot from FAT32, see http://chdk.setepontos.com/index.php?topic=6645.0 I don't know if this is confirmed to work with eye-fi, but worth looking into if you have a new camera.

Thanks for the response but my cameras are pre-2011 (G10 & D10).


The helper uses the card's volume id(not label) to identify it as an eye-fi. All their cards have the id "AA52-6922" so if you can find a tool that can rewrite that id (which would have changed when you reformatted, even though the card is supposed to self-restore it) it might help.

Thanks so much, changing the volume id solved the problem.
