Corundum for Alibaba AS02MC04

Introduction

This design targets the Alibaba AS02MC04 FPGA board.

  • SFP+ cages
    • Looped-back 10GBASE-R or 25GBASE-R MAC via GTY transceiver

Board details

  • FPGA: xcku3p-ffvb676-1-e
  • PCIe: gen 3 x8 (~64 Gbps)
  • Reference oscillator: Fixed 156.25 MHz
  • 25GBASE-R PHY: Soft PCS with GTY transceiver

Licensing

  • Toolchain
    • Vivado Standard (enterprise license not required)
  • IP
    • No licensed vendor IP or 3rd party IP

How to build

Run make in the appropriate fpga* subdirectory to build the bitstream. Ensure that the Xilinx Vivado toolchain components are in PATH.

On the host system, run make in modules/cndm to build the driver. Ensure that the headers for the running kernel are installed, otherwise the driver cannot be compiled.

How to test

Run make program to program the board with Vivado. Then, reboot the machine to re-enumerate the PCIe bus. Finally, load the driver on the host system with insmod cndm.ko. Check dmesg for output from driver initialization. Run cndm_ddcmd.sh =p to enable all debug messages.
