corundum/fpga/mqnic/520N_MX/fpga_25g

Corundum mqnic for 520N-MX

Introduction

This design targets the BittWare 520N-MX FPGA development board.

• FPGA: 1SM21CHU2F53E2VG
• PHY: Transceiver in 10G BASE-R native mode

Quick start

Build FPGA bitstream

Run make in the fpga subdirectory to build the bitstream. Ensure that the Intel Quartus Pro toolchain components are in PATH.

Build driver and userspace tools

On the host system, run make in modules/mqnic to build the driver. Ensure the headers for the running kernel are installed, otherwise the driver cannot be compiled. Then, run make in utils to build the userspace tools.

Testing

Run make program to program the board with Quartus. Then, reboot the machine to re-enumerate the PCIe bus. Finally, load the driver on the host system with insmod mqnic.ko. Check dmesg for output from driver initialization, and run mqnic-dump -d /dev/mqnic0 to dump the internal state.
