EtherCAT slaves do not respond correctly..? #23

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
To reproduce:

1. Turn on EtherCAT slaves, connect to master.
2. Insert kernel modules rt_shm and rtai_controller.
3. Monitor dmesg output.

The dmesg output looks something like:
"EtherCAT WARNING 0: 1 datagram TIMED OUT!"
"EtherCAT WARNING 0: 1 datagram UNMATCHED!"
"EtherCAT ERROR 0: Failed to receive address clearing datagram: Datagram error."

And:

"Slave does not support changing the PDO mapping."

This happens before the controller runs through the state machine to initialize 
the EtherCAT slaves.
