[etherlab-users] packets timed out

[Raz Ben Yehuda]

Hello

I loaded etherlab on 3.2.0 preempt rt kernel. I connected point to point
a slave to my controller.

$ ethercat master
Master0
 Phase: Idle
 Active: no
 Slaves: 1

     Loss rate [1/s]:          0      0      0

   Application time: 0
                     2000-01-01 00:00:00.000000000

the eth0 is 100mbps e100, but i have not patched yet but used the
generic driver.
when i issue the upload command:

$ ethercat upload -t int8 -p 0 0x2003 0x01

I sometime get a reply "Data type mismatch. Expected int8 with 1 byte,
but got 0 byte."

dmesg shows me that i have packets timed out.
