Ah. Yes. Ok, this is a problem with the software running on your raspberry pi. There is one version which works with the older Corr library and boffiles, and a newer image for fpg files and CasperFpga. I'll update the image online (I think this is a "Corr" one). For now you can find an image in Berkeley at: acme1:/home/kocz/rpi_casperfpga.img.gz
If you gunzip and burn this to an SD card, your pi should start working with CasperFpga.
