[Etherlab-users] "Master0 dead" and unable to check fro masters/slaves

[Andreas Stewering-Bone]

Dear Barie,

You are using the master branch of the EtherCAT master. 
This branch is actually under heavy delevolment and not stable.
Please use the stable-1.5 branch and retry again.

Also send the output off
- ip a
- ethercat ma
-ethercat sl


Best regards

Andreas
