一、内核编译安装
1.下载相关资料包
当前环境为ubuntu18.04版本，已安装ros-melodic环境，先查看当前系统内核版本
uname -a得出：
Linux robotarm 5.4.0-89-generic #100~18.04.1-Ubuntu SMP Wed Sep 29 10:59:42 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux下载补丁，内核版本与补丁版本保持一致。
补丁下载地址： https://www.kernel.org/pub/linux/kernel/projects/rt/
内核地址： http://www.kernel.org/pub/linux/kernel/
patches-5.4.154-rt65.tar.gz 20-Oct-2021 15:15 389
linux-5.4.154.tar.gz 17-Oct-2021 08:48 163M2、
2.解压
先解压内核，再把补丁拷贝进内核目录
tar -xvf linux-5.4.154.tar.gz
tar -xvf patches-5.4.154-rt65.tar.gz
mv patches linux-5.4.154
cd linux-5.4.154
3.合并补丁
将patches解压出来的文件合并
#!/bin/sh
cat ./patches/series | while read line
do
patch -p1 < ./patches/$line
done4.内核配置
sudo chrt 10 bash
make mrproper
cp /boot/config-5.4.0-89-generic .config安装依赖包
sudo apt-get install libncurses-dev bison flex bc libelf-dev
sudo apt-get install libssl-dev
进入菜单配置界面
make menuconfig
进入“General setup”, 在"Preemption Model"中选择“Fully Preemptible Kernel(Real-Time)”
这里按enter键会先保存好然后返回上一层，然后再用方向右键移到exit那里，然后返回上一层，找到Device Drivers
找到staging drivers ,(在比较后面，慢慢找)，然后按空格键，把它去掉。
然后save 、exit。
可以使用lscpu指令查看当前cpu的逻辑核心数：4

L1i 缓存： 32K

执行下面的指令，其中，'getconf_NPROCESSORS_ONLN' 表示内核数量是多少个。编译内核的操作会比较耗时，所以尽可能的开启多个逻辑核同时编译，可以减少编译时间。
make -j$(getconf _NPROCESSORS_ONLN)
或者 make -j4
安装内核模块
make modules_install
安装内核
make install 然后报错了
# make modules_install
sed: 无法读取 modules.order: 没有那个文件或目录
Makefile:1351: recipe for target '_modinst_' failed
make: *** [_modinst_] Error 2
# make modules
CALL scripts/checksyscalls.sh
CALL scripts/atomic/check-atomics.sh

CHK include/generated/compile.h
CHK kernel/kheaders_data.tar.xz
make[1]: *** 没有规则可制作目标“debian/canonical-certs.pem”，由“certs/x509_certificate_list” 需求。 停止。
Makefile:1734: recipe for target 'certs' failed
make: *** [certs] Error 2
我猜可能是因为我的当前内核版本跟下载的内核版本不一样吧，就想重新去官网下载了跟5.4.0-89一样的版本，好家伙，压根没有89的。
还是先试着解决报错的问题，一个一个百度,编辑.config文件，把下面两行注释掉
gedit .config
CONFIG_MODULE_SIG_KEY="certs/signing_key.pem"
CONFIG_SYSTEM_TRUSTED_KEYS="debian/canonical-certs.pem"make -j4
make modules_install -j4
make install
root@robotarm:/home/robotarm/文档/ethercat_master_file/linux-5.4.154# make install -j4

（我似乎下载了好几次内核吧，反正这次是154版本的)
查看编译后的内核大小: 18G
du -sh
18G .
5.修改grub启动配置文件
安装完内核之后，再手动更新一下grub。
update-grubgedit编辑/etc/default/grub文件，改动三处：
将 "GRUB_TIMEOUT_STYLE=hidden" 注释掉（在前面加上“#”）。
将 "GRUB_TIMEOUT" 的值改为“15”。
将 "GRUB_CMDLINE_LINUX_DEFAULT" 的值改为“text”。
再更新一遍配置文件
update-grub6.测试
reboot重启后进入GRUB界面,选154那个，然后
uname -a
Linux robotarm 5.4.154-rt65 #1 SMP PREEMPT_RT Thu Nov 4 10:21:44 CST 2021 x86_64 x86_64 x86_64 GNU/Linux
好像成功了，测试一下，运行五个线程，线程优先级为80，无限循环。
T: 0 序号为0的线程
P: 0 线程优先级为0
C: 9397 计数器。线程的时间间隔每达到一次，计数器加1
I: 1000 时间间隔为1000微秒(us)
Min: 最小延时(us)
Act: 最近一次的延时(us)
Avg： 平均延时(us)
Max： 最大延时(us)
sudo apt-get install rt-tests
sudo cyclictest -t 5 -p 80 -n
# /dev/cpu_dma_latency set to 0us
policy: fifo: loadavg: 3.63 1.72 0.90 1/711 2801

T: 4 ( 2801) P:80 I:3000 C: 2086 Min: 3 Act: 4 Avg: 5 Max: 27看起来误差不大，跑ethercat通信应该没有问题
二、安装igh主站
具体详情见另一篇博客

Libraries have been installed in:
/usr/local/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the 'LD_RUN_PATH' environment variable
during linking
- use the '-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to '/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

三、装igh的错误操作
网上的一些教程偏低而且麻烦，配置的很多东西为也不知道是什么。。。，总之就是错的
下载
http://etherlab.org/download/ethercat/ethercat-1.5.2.tar.bz2
tar -vxf ethercat-1.5.2.tar.bz2
cd ethercat-1.5.2/
./configure --with-linux-dir=/usr/src/linux-headers-5.4.0-89-generic/ --enable-8139too=no --enable-wildcards=yes
make -j4
make modules -j4
然后报错了

。。。可能，也许，是内核版本不对吧，重新按照个试试，然后手滑，不小心卸载了一些东西，问题应该不大吧。
下列软件包是自动安装的并且现在不需要了：
amd64-microcode intel-microcode iucode-tool linux-hwe-5.4-headers-5.4.0-84 linux-hwe-5.4-headers-5.4.0-87 linux-hwe-5.4-headers-5.4.0-89
linux-image-generic-hwe-18.04 thermald
使用'sudo apt autoremove'来卸载它(它们)。
下列软件包将被【卸载】：
linux-generic-hwe-18.04 linux-headers-5.4.0-87-generic linux-headers-5.4.0-89-generic linux-headers-generic-hwe-18.04
linux-signed-generic-hwe-18.04
升级了 0 个软件包，新安装了 0 个软件包，要卸载 5 个软件包，有 5 个软件包未被升级。
解压缩后将会空出 28.6 MB 的空间。

赶紧重新下载回来
sudo apt install linux-headers-5.4.0-89再认真看看报错信息，好像是里面的参数传的值少了，可能是内核版本5.4的少了点什么吧
sudo gedit devices/generic.c +154
// dev->netdev = alloc_netdev(sizeof(ec_gen_device_t *), &null, ether_setup);
dev->netdev = alloc_netdev(sizeof(ec_gen_device_t *), &null,NET_NAME_UNKNOWN, ether_setup);
sudo gedit master/ethernet.c +150
// if (!(eoe->dev = alloc_netdev(sizeof(ec_eoe_t *), name, ether_setup))) {
if (!(eoe->dev = alloc_netdev(sizeof(ec_eoe_t *), name,NET_NAME_UNKNOWN, ether_setup))) {还有一个问题是这样的
int sock_create_kern(struct net *net, int family, int type, int proto, struct socket **res);
linux2.x版本是：
int sock_create_kern(int family, int type, int protocol, struct socket **res)
{
return __sock_create(family, type, protocol, res, 1);
}
linux3.x的版本是
int sock_create_kern(int family, int type, int protocol, struct socket **res)
{
return __sock_create(&init_net, family, type, protocol, res, 1);
}
linux4.x的版本是
int sock_create_kern(struct net *net, int family, int type, int protocol, struct socket **res)
{
return __sock_create(net, family, type, protocol, res, 1);
}
而在generic.c里的调用方式是
ret = sock_create_kern(PF_PACKET, SOCK_RAW, htons(ETH_P_ETHERCAT),&dev->socket);
int
所以会导致出问题
在4.x的版本可以这样调用
sock_create_kern(&init_net, family, type, protocol, res)；
所以第211行改为
// ret = sock_create_kern(PF_PACKET, SOCK_RAW, htons(ETH_P_ETHERCAT),
ret = sock_create_kern(&init_net,PF_PACKET, SOCK_RAW, htons(ETH_P_ETHERCAT),
然后再编译一次
