Working install for :

    user@debian:~$ uname -a
    Linux debian 5.10.0-4-rt-amd64 #1 SMP PREEMPT_RT Debian 5.10.19-1 (2021-03-02) x86_64 GNU/Linux
    user@debian:~$

https://www.etherlab.org -> "report typo in INSTALL, =>./bootstrap"

The lazy way :

https://github.com/grotius-cnc/debian_distro_live_build_post_tweaking/releases/download/1.0.0/ethercat-master.deb

To install : sudo dpkg -i ethercat-master.deb To Remove : sudo apt-get remove ethercat-master && sudo rm -rf /opt/ethercat

Add sources to /etc/apt/sources.list

    echo "deb http://ftp.de.debian.org/debian bullseye main contrib non-free" >> /etc/apt/source.list
    echo "deb-src http://ftp.de.debian.org/debian bullseye main contrib non-free" >> /etc/apt/source.list
    echo "deb http://security.debian.org/debian-security/ bullseye-security main" >> /etc/apt/source.list
    echo "deb-src http://security.debian.org/debian-security/ bullseye-security main" >> /etc/apt/source.list
    echo "deb http://deb.debian.org/debian buster main contrib non-free" >> /etc/apt/source.list
    echo "deb-src http://deb.debian.org/debian buster main contrib non-free" >> /etc/apt/source.list
    echo "deb http://security.debian.org/debian-security buster/updates main contrib" >> /etc/apt/source.list
    echo "deb-src http://security.debian.org/debian-security buster/updates main contrib" >> /etc/apt/source.list
    apt-get update

    apt-get install git autoconf libtool linux-headers-$(uname -r)
    git clone https://gitlab.com/etherlab.org/ethercat.git
    cd ethercat
    git checkout stable-1.5 
    ./bootstrap
    ./configure --help
    ./configure --enable-generic --disable-8139too
    make
    make all modules
    make modules_install install
    depmod

Copy ethercat launcher :

    cp -f /opt/ethercat/script/init.d/ethercat /etc/init.d/

Make ethercat launcher executable :

    chmod +x /opt/ethercat/script/init.d/ethercat

copy ethercat mac and driver config sheet to system :

    mkdir -p /etc/sysconfig/
    cp -f /opt/ethercat/script/sysconfig/ethercat /etc/sysconfig/

Retrieve mac adres :

    echo MASTER0_DEVICE="$(cat /sys/class/net/enp0s25/address)" > /etc/sysconfig/ethercat

We choose the generic driver to activate :

    echo DEVICE_MODULES="generic" >> /etc/sysconfig/ethercat

From etherlab orginal :

    chmod go+rwx /etc/udev/rules.d/99-ethercat.rules
    echo "KERNEL=="\"EtherCAT[0-9]*\"", MODE="\"777\"", GROUP=""\"ethercat\"" > /etc/udev/rules.d/99-ethercat.rules

Start ethercat

    /etc/init.d/ethercat start

Or if previous start fails :

    systemctl restart systemd-modules-load.service
    /etc/init.d/ethercat start
