Hello all,
I've got problems to install ethercat master on my Pi3 with Raspbian.
I've got a 4.4.34-v7+ kernel with the matching kernel headers (got them
via apt-get install raspberrypi-kernel-headers).
My steps:
1) Get newest Version via hg.
2) Execute ./bootstrap
3) Execute ./configure --enable-tool --enable-generic --disable-8138too
4) Execute make doc #Some Errors appear, but it shouldn't be the point.
5) Execute sudo make install
6) Execute sudo make modules_install
7) sudo depmod
So good, so far and my kernel modules are under /lib/modules.
And now the trouble starts.
I googled a little bit and it was said that /etc/default/ is ca. the
equivalent of /etc/sysconfig/. On the other hand I would interpret the
manual that my folder with systemd is the right on.
Also 'ln -s etc/init.d/ethercat /etc/init.d/' doesn't seem to work well.
In my inid.d folder is only a warning symbol and can't be executed via
terminal.
Ok I try to go further anyway:
pi@raspberrypi:~$ insserv ethercat
insserv: ethercat: No such file or directory
At this point their might be my error anywhere, but I've got no clue
what to do and try to start something anyway.
So I edited my eth0 MAC-Adress and as DEVICE_MODULES I type in
"generic".
I execute 'ethercatctl start' via terminal and something seems to be
running.
Via dmesg I can see, that my I/O Slave is found and in PREOP, but I
can't communicate with them via the command-line-tool.
Is there maybe an easier way for RPIs?
Did I make a (simple) mistake?
I hope you can help.
Greets,
Soron
