Polling eats up significant cpu time
Hello All.
Thanks a lot for linux implementation of ccat driver.
I noticed that the driver eats up a lot of resources because of polling (~30 - 40% on CX5020).
Are there plans to add interrupts support instead of polling mechanism?
Or may be there is a way to synchronize polling time with ethercat cycle?
How do you do it in Twincat?
best regards,
Alexey
ccat and etherlab on CX5130
Hi.
Im trying to install CCAT and etherlab on a CX5130 im using ubuntu server 18.04.4 lts with fully preempt linux-4.19.106-rt45 kernel installed for realtime operation.
i run the installation of ccat
$make
and
sudo make install
I can see that the ccat modules have been installed (see bellow)
$lsmod | grep ccat
ccat_update 16384 0
ccat_systemtime 16384 0
ccat_sram 16384 0
ccat_gpio 16384 0
ccat_netdev 16384 0
ccat 16384 2 ccat_sram,ccat_update
After this im trying to install etherlab master in the using the guide from the documentation
$hg clone http://etherlabmaster.hg.sourceforge.net/hgweb/etherlabmaster/etherlabmaster ethercat-hg
$cd ethercat-hg
$hg update stable-1.5
$patch -p1 < ../CCAT/etherlab-patches/0001-convert-ccat-to-mfd.patch
$patch -p1 < ../CCAT/etherlab-patches/0002-zalloc.patch
$./bootstrap
$./configure --disable-8139too --enable-ccat_netdev --enable-kernel --enable-cycles --enable-hrtimer --prefix /opt/etherlab
$make
$make modules
$make install
$make modules_install
$mkdir /etc/sysconfig
$cd /opt/etherlab
$cp etc/sysconfig/ethercat /etc/sysconfig/
$ln -s etc/init.d/ethercat /etc/init.d/
Then i change the MASTER0_DEVICE variable to the mac address of the port i want to use and DEVICE_MODULES variable to "ccat" in /etc/sysconfig/ethercat
And finally i try to start it with /etc/init.d/ethercat start but i just get the error
Starting EtherCAT master 1.5.2 modinfo: ERROR: Module ec_ccat not found.
done
And the modules do not show up when i run
$lsmod | grep ccat
I uninstalled it to try another way with https://github.com/icshwi/etherlabmaster
$echo "ETHERCAT_MASTER0=enp3s0" > ethercatmaster.local
$make init
$echo "WITH_DEV_GENERIC = NO" > configure/CONFIG_OPTIONS.local
$echo "WITH_DEV_CCAT = YES" >> configure/CONFIG_OPTIONS.local
$make ccat_patch
$make build
$make install
$make dkms_add
$make dkms_build
$make dkms_install
$make setup
Everything installs fine with and i end up with the modules installed
$lsmod | grep ccat
ec_ccat_netdev 20480 0
ec_master 258048 1 ec_ccat_netdev
ccat_update 16384 0
ccat_systemtime 16384 0
ccat_sram 16384 0
ccat_gpio 16384 0
ccat 16384 2 ccat_sram,ccat_update
I can't seem to get the ethercat to work after this
and dmesg gives me this
[ 21.195204] ccat: loading out-of-tree module taints kernel.
[ 1547.697135] PKCS#7 signature not signed with a trusted key
[ 1547.729268] EtherCAT: Master driver 1.5.2 unknown
[ 1547.740860] EtherCAT: 1 master waiting for devices.
[ 1547.876607] PKCS#7 signature not signed with a trusted key
Am i missing something? or am i doing something wrong?

CCAT: ubuntu 20.04 kernel modules don't load
Hello,
After compiling the drivers (with UBUNTU 20.04) the drivers don't load.
error:

Using CCAT on a CX2030 running Ubuntu
We are trying to get a Beckhoff CX2030 Industrial PC running Ubuntu to accept input from Beckhoff EL3024 modules using Etherlab with the CCAT modules. However, we haven't been able to initialise the EtherCAT connection, the EtherCAT messages stop at EtherCAT: 1 master waiting for devices.
Could you give us a hand troubleshooting this issue?
Below are the steps we took to install Etherlab and CCAT on a clean Ubuntu 14.04.5 install on the CX2030.
- Install Ubuntu Server 14.04.5 64bit
- Install build tools
sudo apt install mercurial automake libtool build-essential - Download Etherlab and CCAT
wget http://etherlab.org/download/ethercat/ethercat-1.5.2.tar.bz2
tar -xjf ethercat-1.5.2.tar.bz2
hg update stable-1.5
wget https://github.com/Beckhoff/CCAT/raw/master/etherlab.bundle
hg unbundle etherlab.bundle
hg update
./bootstrap
- Build Etherlab
./configure --disable-8139too --enable-ccat
make
make modules
sudo make install
sudo make modules_install
The last line raises the following error, but apparently that can be ignored
testuser@ubuntu:~/ethercat-hg$ sudo make modules_install

- Pull up the interface
sudo ifconfig eth0 192.168.100.164 up
- Start ethercat:

And that's where it stops. Ethercat is never able to
If I use the generic module instead, ethercat at least recognises that there are slaves on the bus, but the initialisation doesn't complete successfully:

CCAT and CX52XX devices
Hi,
Simple question: does CCAT works on CX52XX devices?
unittest failing
When I try to run "make unittest", i get a "chmod: cannot access '/dev/ccat_*': no such file or directory.
I am not sure of what it means. I get no complain at make/make install
unbundle of CCAT on Debian Jessie
I am trying to get my Beckhoff CX2030 with Debian Jessie running using CCAT modules. Here is my process for acquiring Etherlab and CCAT.
The problem arises when I try to unbundle the etherlab.bundle
hg clone http://hg.code.sf.net/p/etherlabmaster/code ethercat-hg
cd ethercat-hg
hg update stable-1.5
wget https://github.com/Beckhoff/CCAT/blob/master/etherlab.bundle
hg unbundle etherlab.bundle
The error I receive is:
abort: etherlab.bundle: unknown bundle version 20
Do you know what might cause this, or how to solve?
No interface loaded
Hello,
I integrated this module to our Buildroot tree and it compiled fine. However, after running modprobe, nothing happens. I would expect an interface to be created (such as ecat, ecat0 or whatever) or at least a message in dmesg.
I am working with a CX9020 (no DMA). I tried to comment all lines except the one refering to emi in the ccat_driver structure at the top of module.c. It don't see any difference
Do you have any clues?
Have a nice day,
Vincent
