i am using this link to install ethercat: gist.github.com/Bouni/8b4532d0bdf012bd83c65d3eb62f8aa2
i get error when i finish installing and run command "ethercat master" , the error is :
cnc@raspberrypi:~$ ethercat master
Failed to obtain number of masters: Failed to open master device /dev/EtherCAT0: No such file or directory

 

 Obsolete instructions.

Please try this. It should work for the official pi image of 2.9.2

Good point. the source method and the repository files are stored in different locations so it probably gets confused

which kernel should i install, and if there are steps to follow it would be appreciated

thanks i fixed the error where do i get the linuxcnc-ethercat repository because i cannot locate the package

If you use the official image from the downloads page, the ethercat packages should be dependencies of the linuxcnc-ethercat driver and would normally get installed automatically (but I don't use a pi so I can't check this, it may not work on your platform). Certainly ethercat should install ok

Otherwise follow these instructions.
