NetFPGA-1G-CML从零开始环境配置

前言

偶得一块NetFPGA-1G-CML，跟着github对NetFPGA-1G-CML的入门指南，一步步把配置环境终于搭建起来，下面重新复现一下此过程。期间感谢开发板的技术人员支持与帮助，得以成功配置环境。

https://github.com/NetFPGA/NetFPGA-public/wiki/NetFPGA-1G-CML-Getting-Started-Guide

实验工具

下为工具照片：

1、操作系统的选择

官方推荐Fedora 20，于是我也选择了该操作系统。

可参照这篇文章：制作Linux(Fedora、Ubuntu、CentOS)优盘启动

2、Xilinx开发工具的下载

这个是整个环境安装中最耗费时间的一个地方，建议在windows下用迅雷下载，然后转到fedora下，因为文件相当庞大。之前笔者也下了下列两个工具的最新的版本，可中途也出了莫名其妙的问题，最终成功的环境还是以以下两个工具为基础。

3、获得NetFPGA-1G-CML对应github仓库的权限

在次NetFPGA官网的链接中填入你的相关信息，则工作人员会把拉到对应仓库下，然后可以clone下来到本地。

以下步骤皆基于本仓库。

4、Fedora 20操作系统环境所需配置的安装

下面简单罗列命令，至于每个命令所需安装的内容是为何物，请查看Getting Started Guide的Operating System Setup以及Reference Operating System的Additional Required Installation Packages。

  1.   sudo yum install '*stdc*'
  2.   sudo yum install libsigc++ libsigc++.i686 qt.i686 qt
  3.   sudo yum groups mark convert
  4.   sudo yum group install "Fedora Eclipse"
  5.   sudo yum install qgit wireshark wireshark-gnome
  6.   sudo yum install python
  7.   sudo yum install scapy
  8.   sudo yum install fxload
  9.   sudo yum install bison byacc flex
  10.   sudo yum install glibc.i686
  11.   sudo yum install kernel-devel
  12.   sudo yum install libusb-devel
  13.   sudo yum install libpcap-devel
  14.   sudo yum install libnet-devel

其后四个命令，由于笔者在安装过程中采用是按tab键得到，相关名称可能会有点差异，具体看操作系统级别（32bit or 64bit）选择安装。

5、环境配置，以及跑一个demo

Step1、获得git仓库权限后，把仓库clone到本地

tip：切记此时你已经获得了该仓库的权限（有时候邮件没收到，可能在垃圾箱里面）

git clone https://github.com/NetFPGA/NetFPGA-1G-CML-live.git

Step2、建立编译环境路径变量

  1.   source /opt/Xilinx/14.6/ISE_DS/settings64.sh
  2.   source /opt/Xilinx/Vivado/2015.2/settings64.sh

路径的信息保存于该仓库的文件bashrc_addon_NetFPGA_10G中，记得根据实际路径进行修改，比如笔者的仓库位于/home/netfpga/Program/NetFPGA-1G-CML-live，所以笔者该文件的信息修改如下：

  1.   export NF_ROOT=${HOME}/Program/NetFPGA-1G-CML-live
  2.   export NF_DESIGN_DIR=${NF_ROOT}/projects/reference_nic_nf1_cml
  3.   export NF_WORK_DIR=/tmp/${USER}
  4.   export PYTHONPATH=${NF_ROOT}/lib/python:${NF_DESIGN_DIR}/lib/Python:${NF_ROOT}/tools/scripts:
  5.   export LD_LIBRARY_PATH=${NF_ROOT}/lib/java/NetFPGAFrontEnd/bin:${LD_LIBRARY_PATH

然后执行命令

source bashrc_addon_NetFPGA_10G

为了更好确认上部是否写对，可以执行一下命令看看输出

echo $NF_ROOT

此时如果输出为仓库的所在的绝对路径，就证明正确了。

Step3、 Build the Libraries and IP

此处由于笔者还不了解大概这些库的功能，中文无法直接翻译。

tip：这个步骤的过程一定要基于ISE已经导入license

To build the hardware test libraries for the hardware and simulation tests:

  1.   cd $NF_ROOT
  2.   make hwtestlib

To build the IP cores used by the NF1-CML projects:

make cml_cores

上述两个步骤，若无出现make ...错误都表示步骤已经成功进行。

Step4、编译一个工程

本次 $NF_DESIGN_DIR所选择的工程为 reference_nic_nf1_cml一个简单的网卡（若想编译其他工程，记得去bashrc_addon_NetFPGA_10G修改对应的$NF_DESIGN_DIR路径）

  1.   cd $NF_DESIGN_DIR
  2.   make

此时你会等待相当长的一段时间，最后如果成功后最后两行会显示如下：

  1.   mkdir -p bitfiles
  2.   cp hw/implementation/download.bit bitfiles/reference_nic_nf1_cml.bit

Step5、连接FPGA到主机

笔者是用J12的usb jtag引脚作为连接主机的口，这里主要介绍一下相关驱动的安装，以及一些坑。

如图所示

990007-20170426231120803-549002220.jpg

首先下载usb驱动，驱动：rmdir.de/~michael/xilinx/

驱动安装步骤

  1.   tar -xvf usb-driver-HEAD-xxxxxxx.tar.gz
  2.   cd usb-driver-HEAD-xxxxxxx
  3.   source /opt/Xilinx/13.4/ISE_DS/settings64.sh 这里要相应改变
  4.   make
  5.   ./setup_pcusb
  6.   cp libusb-driver.so /usr/local/lib/libusb-jtag-driver.so
  7.   export LD_PRELOAD=/usr/local/lib/libusb-jtag-driver.so

之后用命令lsusb可以看到

  1.   [netfpga@localhost bin]$ lsusb
  2.   Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
  3.   Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
  4.   Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  5.   Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  6.   Bus 001 Device 003: ID 1443:0007 Digilent Development board JTAG //这个就是我们的设备
  7.   Bus 002 Device 003: ID 1c4f:0002 SiGma Micro Keyboard TRACER Gamma Ivory
  8.   Bus 002 Device 004: ID 192f:0916 Avago Technologies, Pte.

可是通过impact &打开ISE impact又有提示如下图所示问题，需重新装驱动

990007-20170426231129678-1713289875.jpg

990007-20170426231137709-179559153.jpg

后来在技术人员帮助下，有了一个解决答案，具体的下载文件请移步另外一篇博客：Digilent Xilinx USB Jtag cable。

根据上述做完，即可从impact &看到我们的FPGA芯片。

990007-20170426232741240-627812983.jpg

Step6、烧写程序到FPGA中

进入到项目文件夹下，执行以下命令

make download

然后烧写成功后，会有如下输出

  1.   INFO:iMPACT - '1': Checking done pin....done.
  2.   '1: Programmed successfully.
  3.   Elapsed time = 62 sec.
  4.   rm -f bitfiles/download.bit

Step7、安装NetFPGA-1G-CML作为系统设备

首先确保已经把NetFPGA-1G-CML开发板插到PCIe口上，如图所示

990007-20170426231202490-1796897455.jpg

然后执行以下命令，并可看到该设备

  1.   lspci | grep Xilinx
  2.   01:00.0 Ethernet controller: Xilinx Corporation Device 4244

安装NetFPGA-1G-CML驱动，在这之前，请在执行一次

  1.   cd $NF_ROOT
  2.   source bashrc_addon_NetFPGA_10G
  3.   make hwtestlib

安装必要组件

sudo yum install kernel-devel-3.11.10-301.fc20.x86_64

编译驱动

  1.   cd $NF_DESIGN_DIR/sw/host/driver
  2.   make

安装驱动

sudo insmod nf10.ko

初始化NetFPGA-1G-CML的四个以太网接口

  1.   sudo ifconfig nf0 up
  2.   sudo ifconfig nf1 up
  3.   sudo ifconfig nf2 up
  4.   sudo ifconfig nf3 up

执行一下ifconfig，可以看到四个以太网卡出现了

  1.   [netfpga@localhost bin]$ ifconfig
  2.   lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
  3.   inet 127.0.0.1 netmask 255.0.0.0

  31.   nf2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
  32.   inet 192.168.202.1 netmask 255.255.255.0 broadcast 192.168.202.255
  33.   inet6 fe80::24e:46ff:fe31:3002 prefixlen 64 scopeid 0x20<link>

  40.    
  41.   nf3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
  42.   inet 192.168.203.1 netmask 255.255.255.0 broadcast 192.168.203.255
  43.   inet6 fe80::24e:46ff:fe31:3003 prefixlen 64 scopeid 0x20<link>
  44.   ether 00:4e:46:31:30:03 txqueuelen 1000 (Ethernet)

  57.   TX packets 5648 bytes 583390 (569.7 KiB)
  58.   TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

Step8、Making Registers

对于这个步骤，笔者较为陌生，编译寄存器的相关映射，再次只做操作步骤，原理还需细究

  1.   $ cd $NF_DESIGN_DIR/hw
  2.   $ make regs

在此处步骤，笔者遇到一个莫名其妙的问题，编译不通过，然后出去吃个饭，重启了一下，重新打开makefile保存了一下，竟莫名其妙的解决了.(已解决)
解决方案，重新打开一个终端，执行命令

  1.   source /opt/Xilinx/14.6/ISE_DS/settings64.sh
  2.   source bashrc_addon_NetFPGA_10G

然后在去执行上述步骤

Step9、Verify the Design in Hardware with the Test Infrastructure

最终步骤验证实验，并把四个以太网口按如图所示接上，NF0---NF3，NF1---NF2

990007-20170426231223631-1985161317.jpg

  1.   cd $NF_ROOT/tools/bin
  2.   su -c "./nf_test.py hw --major loopback --minor maxsize"

然后如果测试成功会有如下显示：

  1.   Running global setup... PASS
  2.   Running test both_loopback_maxsize... PASS
  3.   Running global teardown... PASS

然后在执行一遍ifconfig，可以发现NF0-3各个网卡的收发包较上次执行ifconfig有了上涨

  1.   [netfpga@localhost bin]$ ifconfig
  2.   lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
  3.   inet 127.0.0.1 netmask 255.0.0.0

  7.   RX errors 0 dropped 0 overruns 0 frame 0
  8.   TX packets 10 bytes 940 (940.0 B)
  9.   TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
  10.
