Simon and Bruce have been busy setting to work the Rhino platform and making excellent progress. Last night we had the first successful communications between the two CX4 ports at full throttle. After 10 million 64-bit frames (simultaneous data transmission between CX4 ports), we had zero errors with a 0.5m cable. The eye diagrams look good out to 2m cables, so for long cables we will need to go optical.

The SPI interface is now working through uboot and has been used to probe the RTC and configure the FPGA.

Just three more interfaces to test! GPMC, 1Ge and FMC.
