edit the mercurial configuration file
Code:
sudo hg config --edit
Add
Code:
[extensions] mq =
save and return to
Code:
sudo ./get source.sh
now without mistakes!
you can continue compiling ...
Code:
cd etherlabmaster
Code:
sudo dpkg-checkbuilddeps
Code:
sudo dpkg-buildpackage
Code:
cd ..
Code:
sudo dpkg -i etherlabmaster_1.5.2+xxxxxx_amd64.deb
Code:
sudo dpkg -i etherlabmaster-dev_1.5.2+xxxxxx_amd64.deb
now you just need to edit the ethercat configuration file
Code:
sudo geany /etc/default/ethercat
we apply

sudo update-ethercat-config
works!!!!

I was wondering if there was a slave number limitation on the EtherCAT configuration for linuxcnc. I am trying to run a new device, the config xml file works fine when I plug the device alone, but my system crashes when I put it after 15 other slave on my EtherCAT bus.

Is such a limitation exists, is it overall, or is it per master? My computer has two Ethernet port, so maybe I could use the other one as another master. I am just wondering how I would parametrize it in the /etc/default/ethercat file.

Thank you,

Nicolas


There is a memory limitation on linuxcnc:

In src/hal/hal_priv.h ( github.com/LinuxCNC/linuxcnc/blob/master/src/hal/hal_priv.h )

you have two constant HAL_SIZE and HAL_STACK_SIZE
I've changed
Code:
#define HAL_STACKSIZE 16384 /* realtime task stacksize */
to
Code:
#define HAL_STACKSIZE 32768 /* realtime task stacksize */

and
Code:
#define HAL_SIZE (75*4096)
to
Code:
#define HAL_SIZE (75*8192)

Hi narogon,
I did extend the HAL_SIZE previously. Will try extending the HAL_STACKSIZE too.
I am just wondering
  • what are the difference between those two parameters?
  • is there a physical limitation to extending. i guess you cannot put an number too high as at some point you are physically limited by your hardware. Is there a way to enlarge those sizes and compare it a relevant maximum value, to see how we are from this limit?
Thank you again,

Nicolas

Hi manojpatil,
If you can give more information of the device you are trying to control and the configuration you have so far or you can also pass the project in TWINCAT3 I can take a look if I can help you.
