[etherlab-users] Looking for Slave firmware update example

[Gavin Lambert]

Ah, I missed that in the docs.  I suppose it could be needed for the device
to finalise something about the upload internally, though that would seem
unusual.  But IIRC those particular devices have to be sent SDO parameters
before they’ll accept going to OP anyway.  The docs look like generic (not
model-specific) instructions so you might be able to get away with skipping
that step, or possibly just going to PREOP or something instead.

Thanks.

 

The documentation for this module (from Beckhoff) doesn't mention that a
filename should be set so I will go with the default .efw filename.

 

The documentation says to change to OP at the end.  I can't see that it
would be necessary either.

 

Graeme.

The change to OP seems wrong, but otherwise the procedure below looks about
right.

 

One thing to note is that the foe_write command takes two filenames – the
other you’ve left unspecified (and so will default to the .efw filename) is
the internal name sent to the device.  You’ll have to check with the vendor
whether they require a particular name or whether they’ll accept any name.
(If there’s upgrade instructions in the docs, it probably shows how the
upgrade is done via TwinCAT – you can see what filename is used there, or if
it doesn’t appear to be relevant.)

 

A quick glance at the docs myself suggests that the device doesn’t
particularly care what filename is used.  But to be sure, you will need to
try it.

Hi,

 

I want to update the firmware on an EtherCAT slave (an EL6021 module).  I'm
using the latest 1.5.2 master.

 

I take it that I need to use the "ethercat foe_write" command but I haven't
been able to find what "output-file" name I should be using.  Should it be
the name of the .efw file (or not used so it automatically picks up the name
of the .efw file)?

 

 

Is this general procedure correct? :

- ethercat states -p1 INIT

- ethercat states -p1 BOOT

à check current state is BOOT

- ethercat foe_write -p1 /tmp/EL6021_FW06.efw

- ethercat states -p1 INIT

- ethercat states -p1 OP

à repower the slave and check new firmware is active

 

 

Thanks,

Graeme Foot
