I guys, im going crazy with my problem:
I managed to get the chdk work on my Sx1, making the 2 partitions and placing the boot file in the small one, and the chdk folder in the big one.
All recognized, works well EXCEPT that I can't see the RAW files created with chdk.
With the internal file browser I can see them in the same folder as jpeg, but when I connect the camera to windows, only the jpegs are shown (it's not a windows problem).
The ONLY way is to swap partitions with sdminste.exe and then I can read all the folders/files, but I can't no more swap the partitions, no matter how. I have to rebuild everything.
All the same with the DNG.
I hope that someone can understand my problem, thanks.
