[etherlab-users] Timeout while waiting for Sdo upload response

[Erwin Burgstaller]

Hi,

Having sent a reply with wireshark dumps attached, which still didn't
appear on the list, because of it's too large attachments, I've waited
for a reply until now.

The Message was this and did cross the reply from Florian:

| Funny news!
| 
| If I run the bus through a Alied Telesyn FS709FC it works.
| 
| So it seems, there's something to fast, when starting without the
| switch. Unfortunately I cannot watch with wireshark without the
| switch. Hm, can I?
| 
| Found a solution: It's a little bit complicated but running wireshark on
| the same machine goes like this:
| 
| 1) Unplug the ethernet cable, so there's no link on the master's side.
| 
| 2) Run this commands: 
| 
|    /etc/init.d/ethercat stop; /etc/init.d/ethercat start; /sbin/ifconfig ecdbgm0 up;
| 
| 3) Start wireshark and select ecdbgm0 as capture interface, start
|    capturing!
| 
| 4) Plug in the cable, so the master will see the link and will start with
|    bringing up the bus.
| 
| So I've got two dumps to attach, one with and one without
| switch. 
| 
| Starting with the switch in between, it worked again. Without switch
| there was the sdo timeout.

OK fine. I forgot about that debug possibility, should be easier to read
than that punch of wireshark log data.

The log entries, in case it doesn't work:

This are the log entries written in case it works (over the switch):

I've verified the firmware of the slave with Beckhoff's support: there's
no newer version. I've also tried another EL6001, we've got 2 weeks ago,
with the same result.

Twincat as well as the command

ethercat upload -p1 -tstring 0x100A 0

shows the software version as V00.04
