Internal SDO requests now synchronized with external requests.
Internal SDO requests are managed by master FSM and can conflict with
external requests managed by slave FSM. The internal SDO requests
includes SDO requests created by an application and external request are
typical created by EtherCAT Tool for SDO upload/download or a directory
fetch initiated with ethercat sdos command. The conflict will cause a
FPWR from an external request to be overwritten by a FPWR from an
internal SDO request (or oppersite) in the same "train" of datagrams.

Building and installing
=======================
The complete build and installation procedure is described in the respective
section of the documentation available from http://etherlab.org/en/ethercat.
-------------------------------------------------------------------------------
For the impatient: The procedure mainly consists of calling
$ ./boostrap # to create the configure script, if downloaded from the repo
$ ./configure
$ make all modules
... and as root:
# make modules_install install
# depmod
... and linking the init script and copying the sysconfig file from $PREFIX/etc
to the appropriate locations and customizing the sysconfig file.
# ln -s ${PREFIX}/etc/init.d/ethercat /etc/init.d/ethercat
# cp ${PREFIX}/etc/sysconfig/ethercat /etc/sysconfig/ethercat
# vi /etc/sysconfig/ethercat
Make sure, that the 'udev' package is installed, to automatically create the
EtherCAT character devices. The character devices will be created with mode
0660 and group root by default. If you want to give normal users reading
access, create a udev rule like this:
# echo KERNEL==\"EtherCAT[0-9]*\", MODE=\"0664\" > /etc/udev/rules.d/99-EtherCAT.rules
Now you can start the EtherCAT master:
# /etc/init.d/ethercat start
Have a look at the examples/ subdirectory for some application examples.
Have fun!
