Sounds like you do have the official image.... I'll upload it to the wiki! tcpborphserver is a server which runs on the RPI and speaks katcp (the protocol the roaches use). It basically receives katcp read/write/program commands over a TCP socket and then actions them on the FPGA using the chip's JTAG+SPI interface which are made connected to the pi gpio on the snap->pi ribbon cable
