/dev/EtherCAT0 can't start without permission #11

Hi @mcbed,

When you try to activate your master you may encounter few problems:

  1. You haven't started your master and ros2-control might say No such file or directory ``/dev/EtherCAT0
  2. If you started with /etc/init.d/ethercat start it might say Permision denied

If you use /etc/init.d/ethercat start and then sudo chmod /dev/EtherCAT0 (don't know exactly minimum permission required) This way should work.

Normally you don't need to do it. Is your $USER member of ecusers ? You can run $ groups in a shell to check it.

enriLoniterp commented 1 year ago

yes, it is but it doesn't allow me to connect!

My current user is in the ecusers group

you can also use sudo -s or sudo su before running the commands to give all the permissions and hardware access.
