etherlabmaster

Configuration Environment for EtherLab EtherCAT Master at https://sourceforge.net/projects/etherlabmaster/

Role

In order to download, install, setup all relevant components (system library, kernel module, ethercat configuration, and systemd service), one should do many steps manually. This repository was designed for the easy-to-reproducible environment for EtherLab EtherCAT Master. With the following steps, one can run the EtherCAT Master on one dedicated Ethernet port within CentOS, RedHat, and Debian OSs.

Rules

Before the setup the etherlab master, one should define the network port which one would like to use as the EtherCAT Master. Please look at scripts/ethercatmaster.conf, and enable one and disable all others to match the device which one would like to use. With the following command, without changing git status, one can set the master device in the etherlab master configuration:

etherlabmaster (master)$ echo "ETHERCAT_MASTER0=eth0" > ethercatmaster.local

The local file will be used to override the ETHERCAT_MASTER0 variable defined in scripts/ethercatmaster.conf.

One should check the compiling options E3_ETHERLAB_CONF_OPTIONS in configure/CONFIG_MODULE. The default options which ESS uses is

E3_ETHERLAB_CONF_OPTIONS = --disable-8139too --enable-generic --enable-sii-assign=yes --enable-eoe=no

The entire E3_ETHERLAB_CONF_OPTIONS can be override with the "git-ignored" file as follows:

echo "E3_ETHERLAB_CONF_OPTIONS = --disable-8139too --enable-generic" > configure/CONFIG_MODULE.local

Be ready to do the following commands in the specific order:

etherlabmaster (master)$ make init
etherlabmaster (master)$ make patch
etherlabmaster (master)$ make build
etherlabmaster (master)$ make install

Kernel modules are built via dkms

etherlabmaster (master)$ make dkms_add
etherlabmaster (master)$ make dkms_build
etherlabmaster (master)$ make dkms_install
etherlabmaster (master)$ make setup

One should start the ethercat via

etherlabmaster (master)$ sudo systemctl start ethercat

And one can check the master status as follows:

etherlabmaster (master)$ ethercat master

Steps

make init

  • Download the main etherlabmaster-code from sf.net
  • Switch to Revison 9e65f7. We are using the following master revision number as the starting point
[9e65f7] (stable-1.5, tip) by Florian Pose 
Fixed scheduler settings in dc_user example; use CLOCK_MONOTONIC.
