Run node as sudo in ROS 2?
I am trying to activate an open-source master Ethercat. Previously, I started my EtherCAT master from bash. However, now it shows the following error:
Failed to open /dev/EtherCAT0: Permission denied.
On the other side, if I do not create this master manually from bash, it reports that the directory I am searching for does not exist.
How can I launch my EtherCAT0 master with sudo permission, or do you have other solutions that may be more suitable for that case?

How about you assign proper permissions to
/dev/EtherCAT0from terminal once? You need to make sure that the current user have permissions to run/dev/EtherCAT0. For example, look for a groupethercatand make the current user a member of that group, etc.Asked by ravijoshi on 2022-09-20 03:59:44 UTC
