Corundum-proto 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_proto 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_proto.ko. Check dmesg for output from driver initialization. Run cndm_proto_ddcmd.sh =p to enable all debug messages.
