I've been trying to set up my 8gb card for CHDK for awhile now with no luck. I got it working with a 4gb card.
My steps have been
1) download latest stable release with acid
2) insert sd card and highlight "make bootable" "copy files from" inside WICKS and then prepare card
3) remove card
4) wicks copies files and says it is finished.
The problem I am having is for whatever reason the camera is not copying the scripts folder.. when I press the scripts selection in chdk nothing happens. I tried to manually copy the folder from my sd card with the working script (I want the countdown time lapse script mainly) and it still didn't work. I tried this a few times.. tried just setting up the partitions and dragging and dropping the files manually still with little luck.
I got the script to work once, but my camera told me I only had something like 50 shots remaining.. as if the camera was saying the dcim to the partition that only is supposed to be a like 10mb.. it would not save the files to the partition that was 3.5gb.
I have tried this over and over.. pretty frusterating. Can anyone help? I want to shoot a longer time lapse and need this to work!
