RTE3 Use real time ethernet as "normal" ethernet interface
#43
Hey Armin,

unfortunately I must bother you again.
We've tested the new Image in our test-field and I've got the response that it could not get pinged.

Therefore, I've build up a testing environment myself and got the following result:


Code:
Ping wird ausgeführt für 172.16.8.202 mit 32 Bytes Daten:
Antwort von 172.16.8.202: Bytes=32 Zeit=1ms TTL=63
Zeitüberschreitung der Anforderung.

   (25% Verlust),

   Minimum = 1ms, Maximum = 1ms, Mittelwert = 1ms

As you can see, every ~ fourth ping gets timed out. When I use the same setup and configuration for netPi's standard ethernet-Port, the pinging works just fine.

Do you have any idea where this behaviour could come from or where the packages could get lost?

Thanks,
Andi
