[etherlab-users] "Invalid mailbox configuration", how to configure?

[Stefan Löfgren]

I was just about to say yes when I found a seg-fault.
It seems that there is a difference in status from
the version 1.3.2 and to this one. The previous version
got to "Pdo slaves: incomplete". But not this one...

/S



/sys/ethercat/master0/slave000/info:
Segmentation fault

/sys/ethercat/master0/info:
