[En-Nut-Discussion] :Re: Ethernet Failure

Wed Dec 3 13:22:50 CET 2008

  Thank you for your quick reply, yes sorry about that i was dazed by many hours of googling prior to send  the previus mail , it is a rooter it has DHCP capabilities as well as 
support for 10mbit ,the problem is that the green led doesnt flash at all, the yellow led
is active, and my application is a  multithreaded one, the basemon code i used is the .hex provided under the bin folder for the atmega128 ,and it works fine ,while none
of the other precompiled hex files that make use of the ethernet work.
  As i reported in the  last letter what troubles me is that i get an error of zero while the
dhcp client is idle(code 0)  and even this is not stable and  the error might change to 19
some times.
    I would also like to note that the rest of the application works fine,but for some reason 
i cant seem to make ethernet work.
  The supply i use for the rooter is sufficient  i can both connect to it with a pc, and while using the basemon application i see the ethernut displayed in the attached devices normaly, i use the .F revision.
  Any help is welcomed.

You do not mean that really, do you? ;-) A HUB/Switch typically do not 
provide DHCP, but routers do.

Just Basemon or did you try to connected the integrated HTTP server 
(after exiting Basemon by pressing X)?

Try another power supply. Ethernet requires a it more power.

Is the yellow LED lit? Does the green LED flash sometimes?

If you use Basemon to set a fixed IP, it will be stored in EEPROM. When 
the 'Preserve EEPROM' fuse is set (default on shipped Ethernuts), these

setting will be available after burning a new application. No DHCP will 
be required then and the HTTP server sample should run out of the box.

Additional network configuration samples are provided at
http://www.ethernut.de/nutwiki/Nut/OS_Examples
There are ready-made binaries you can try as well.

Which board revision you have? Rev-F or earlier?

Did you create the sample binaries yourself? Sure you chose the right 
configuration file?

The remote station may require a specific feature not available with 
Nut/OS PPP. You need to enable PPP tracing. Add

HWDEF+=-DNUTDEBUG

to app/UserConf.mk _and_ bld/UserConf.mk, replacing app and bld with the 
directory names you configured for the build and sample tree.

In general, this is a non-trivial problem, because initial PPP 
handshaking is complex and greatly differs among access providers.

Has he rebuilt Basemon from the source code delivered with the Ethernut
development kit? (If that is what he has.)

I cannot rebuilt that source and get it work. Seems to have a problem with
initializing the ethernet port.
(http://lists.egnite.de/pipermail/en-nut-discussion/2008-November/010076.htm
l)

The basemon code that was loaded in the ethernut when we purchased it worked
fine. 

While it would be nice to have it back, I figured out a way around it.
