Thanks guys,

updated thread title & first post comments to reflect the changes

Turns out that the code I added to deal with ExFAT cards (which worked) had the side effect of screwing things up for FA16/FAT32 (which worked before). Version 1.05, now on the website, should work properly for all cards!

Thanks to Yannick  Hagmann for reporting the latest problem.

A new version of EOScard is available.

Cards  > 4 GB can not be directly made CHDK bootable - they need to be partitioned.

Skywalker9 wrote a nice tutorial, which is linked here

hope that helps,

PS Note that this thread is in  "DSLR CHDK Development" which is confusingly named - what runs on
    DSLR's is NOT CHDK ! THe DSLR hacks (unlike CHDK) CAN boot from FAT32 cards.

Ok, I really appreciate your development, but just to make it clear:

I have a Canon 350D with firmware 1.0.3 (as suggested) and an 8GB CF card. To make it bootable, and in a safe way, is it enough just with using the Card Tricks V 1.45?? I read somewhere i need a partition, but im not sure if that is what Card tricks actually does.
I just want my 350D with the CHDK tweaks. Particularly Timelapse.

Just to clarify: My CF card is currently formated by the camera.

Update: I did it that way. I got an spooky "err 99" after i used it for a while the 1st time, but now it works ok.

Any clue on the "99 err"?

I just bought 400d chosen mainly because of this hack.

But I can't make it work. Followed the instructions from here but when I put the CF in the slot in the final step, the blue button doesn't light. Instead, the camera turns on, but the display is not working. I can focus but not take pictures. Also, cannot turn off the Camera.

Win 7 x64, CF 4GB (3.8GB)

What am I doing wrong?

Cameras released in 2011 allow CHDK to autoboot on a FAT32 card. I'd like to modify my OSX SDMInst app so that it can do create such cards - currently Mac OSX users who want to create bootable single partition cards > 4GB (e.g. for an A3300) are out of luck.

My question is this - where does the 'BOOTDISK' string have to be written on a FAT32 card? Is it still at x'40'?

Hi,
I searched for this, but found nothing.  Cardtricks (145) is intolerably slow when formatting a 4gb card on my Windows 7 laptop.  I need to use the windows format tool which is very fast and can do fat.
