Well, this doesn't happen often: I assembled the new 0.2 CAT Board and it worked the first time! The Raspberry Pi was able to program it with the SDRAM diagnostic and it passed (showing four green LEDs).

The next steps are:

1. Write the RPi code for programming the bitstream into the SPI flash so I can test the configuration of the FPGA in stand-alone mode.
2. Assemble the SATA I/O. (I checked that the SATA connectors fit their new PCB footprints, but I still need to get the correct termination resistors.)
