专用网卡e1000e + xenomai 3.2.1

2022年6月13日更新

今天装了xenomai内核，然后发现自己的工控机的网卡是 e1000e的，可以使用专用网卡的安装方式，下载地址：https://gitlab.com/etherlab.org/ethercat/-/tree/e1000e-5.10

具体指令：

cd ~/Downloads
sudo tar xf ethercat-e1000e-5.10.tar.gz
sudo cp -r ethercat-e1000e-5.10 ~/xenomai
cd ~/xenomai/ethercat-e1000e-5.10

# 编译igh

sudo ./bootstrap
sudo ./configure --with-module-dir=/lib/modules/5.10.76-xenomai --enable-generic --enable-8139too=no --enable-e1000e --enable-cycles --enable-hrtimer --with-xenomai-dir=/usr/xenomai --prefix=/opt/etherlab
sudo make  #编译
sudo make modules  #编译模块
sudo make install  #安装
sudo make modules_install  #安装模块

# 配置
sudo mkdir /etc/sysconfig  #创建文件夹
sudo cp /opt/etherlab/etc/sysconfig/ethercat /etc/sysconfig/  #复制配置文件
sudo cp /opt/etherlab/etc/init.d/ethercat /etc/init.d/  #复制启动脚本
sudo chmod a+x /etc/init.d/ethercat
sudo update-rc.d ethercat defaults


# 使能
sudo ln -s /opt/etherlab/bin/ethercat /usr/local/bin/ethercat

# 配置用户权限
sudo gedit /etc/udev/rules.d/99-EtherCAT.rules
# 输入下列内容  
KERNEL=="EtherCAT[0-9]*", MODE="0664", GROUP="users" 


# 把相关模块放进系统目录，如果使用通用网卡是这样的
# sudo cp devices/ec_generic.ko /lib/modules/$(uname -r)
# sudo cp master/ec_master.ko /lib/modules/$(uname -r)
# 这边用的是专用网卡
sudo cp devices/e1000e/ec_e1000e.ko /lib/modules/$(uname -r)
sudo cp master/ec_master.ko /lib/modules/$(uname -r)

# 执行
sudo depmod

# 查看网卡MAC地址和类型
ifconfig  
# 得到ethercat通信的地址为 
enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 fe80::fbe:4e35:95d4:4056  prefixlen 64  scopeid 0x20<link>
        ether 00:e8:4c:68:30:de  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 19  bytes 3183 (3.1 KB)

        device interrupt 19  memory 0xf7d00000-f7d20000  

# 配置网卡
sudo gedit /etc/sysconfig/ethercat
#  在大约27行和60行处填入自己的网卡信息
MASTER0_DEVICE="00:e8:4c:68:30:de"    # mac 地址
DEVICE_MODULES="e1000e"    # 通用网卡填generic

# 启动主站
sudo /etc/init.d/ethercat start
# 查看帮助 或者 pdo信息
sudo ethercat --h
ethercat pdos

# 确认ethercat没有问题后，配置系统，让应用程序可以使用 /opt/etherlab/lib 到你的 /etc/ld.so.conf（/opt/ethercatlab前缀实在前面配置ethercat是选定的，默认是/opt/ethercatlab）
sudo gedit /etc/ld.so.conf
# 添加
/opt/etherlab/lib
# 执行
sudo ldconfig
# 测试是否安装，若成功，最后一行会显示 libethercat.so.1 -> libethercat.so.1.1.0
sudo ldconfig -v | grep libether*

ifconfig 查看网卡信息

cd /opt/etherlab 
cd /opt/etherlab

MASTER0_DEVICE="00:e8:4c:68:30:cd"
DEVICE_MODULES="generic"

然后

sudo cp etc/sysconfig/ethercat /etc/sysconfig/
sudo ln -s /opt/etherlab/etc/init.d/ethercat /etc/init.d/

启动主站

robotarm@robotarm:/opt/etherlab$ sudo /etc/init.d/ethercat start
Starting EtherCAT master 1.5.2  done

添加命令行工具

gedit ~/.bashrc
把下面这行加进入
PATH=$PATH:/opt/etherlab/bin
保存，然后
source ~/.bashrc
sudo depmod

robotarm@robotarm:/opt/etherlab$ ethercat
