Ethernet

ModjeskaTech1 · January 28, 2013, 9:10pm

I am trying to get ENC28 1.1 working.

It blows up when I do the listenSocket.Bind(ep);

I also cannot get an IP address, but also tried to bind statically.

I tested the cable on another computer and got an IP address fine.

Of course it will “blow up” when you bind to a socket, if you can’t get an IP address !

You need to tell us what device and what firmware version; there’s lots of issues with the 4.2 firmware, but at least knowing what device we’re talking about will help

Mike · January 28, 2013, 10:04pm

I have not done anything with an ENC28 yet. Does a MAC address need to be saved in the network configuration, or at execution time?

ModjeskaTech1 · January 28, 2013, 10:09pm

@ Brett I tried to bind one statically also. The device is a ENC28 1.1. Not sure where to find the firmware information for you, or for what?

This is the main board:
http://www.ghielectronics.com/catalog/product/297

@ Mike I assume that question is for the group not me. I did nothing to set a MAC address on ethernet device.

Thanks fellas.

Marty

Mike · January 28, 2013, 10:53pm

Usually the spider board uses a J11D for Ethernet. The code you are using is for an OSHW device. The Spider is a premium device, which has a different initialization procedure.

This thread has sample code you could modify for ENC28. http://www.tinyclr.com/forum/topic?id=10446&page=2

You want to use the EthernetENC28J60 class.

ModjeskaTech1 · January 28, 2013, 11:11pm

I also have the J11D, are you saying my code should work OK with that?

Thanks,
Marty

ModjeskaTech1 · January 29, 2013, 9:28am

Andre,

That did it.

Seems like there are a lot of ways to handle networking differently depending on the hardware.

Does anyone have any documentation on how that works and what the different classes might be?

Thanks,
Marty

@ andre.m

Hi there. I’m Wondering do I have the right Ethernet_J11D library (mine is showing as v4.0.30319 in VS) ? I can match your coded solution up until.

ethernet_J11D.UseStaticIP(ip, mask, gw);

but I only have the following method call which comes close to this code (my Ethernet_J11D module is called ethernet)

ethernet.Interface.NetworkInterface.EnableStaticIP(ip,mask,gw);

and when the Interface_NetworkAddressChanged(object sender, EventArgs e) event fires I get a 0.0.0.0 ip address.

I am using .netmf 4.2 with appropriate updated firmware on a FEZ spider (4.2.7.0).

I have managed to assign a static address to the FEZ spider using the .netmf low level reference

NetworkInterface networkInterface = NetworkInterface.GetAllNetworkInterfaces()[0];

However I cannot get DHCP to work with any method with a Ethernet_J11D module. Is it possible to get DHCP running on a FEZ spider?

Appsolo1 · February 10, 2013, 7:21pm

@ andre.m.

Apologies.

Correction the ip address is set when the event fires. But I’m still wondering about the difference in methods and if DHCP is possible?

Thank you.

Appsolo1 · February 10, 2013, 7:37pm

looks like i’m answering my own posts here . I Have got DHCP to configure with this call

ethernet.Interface.NetworkInterface.EnableDhcp();

and ip, sub mask and Gateway are right.

Now just wondering about the difference in the method calls before I go deeper into writing code against network functionality. There seems to be a few different versions of the Ethernet_J11D dll floating around inheriting from different classes?

Mike · February 10, 2013, 7:51pm

As part of the 4.2 Premium SDK, the process for initializing the J11D module changed. This was done to allow multiple IP hardware interfaces to
exist on a device, for example hardwire and Wifi. At the present time, only one IP device can be active, but they can be switch
during the running of a program.

Appsolo1 · February 11, 2013, 11:23am

@ Mike

Thanks for that Mike.

So just to clarify. Is ethernet.UseDHCP() a .netmf 4.1 method and the new equivalent in 4.2 is ethernet.Interface.NetworkInterface.EnableDhcp();?

Thanks again.

Gus_Issa · February 11, 2013, 11:26am

The SDK comes out this week adds the gadgeteer Ethernet wrappers back, just like 4.1

Patrick · April 3, 2013, 5:12am

I’ve noticed that nobody sets the mac-address from code. Does this mean that you all expect it to be present from the config.hex and mfdeploy tool?

Patrick · April 3, 2013, 1:12pm

Ok, but when the device (for example fez-spider) is being updated (IFU or MFDeploy) will the mac-address overwritten?

Mike · April 3, 2013, 5:09pm

Since an erase of the device is done, during firmware installation, I would assume that the MAC address is erased and replaced with the default address.

I often set the MAC address in the code.

Patrick · April 3, 2013, 5:19pm

I also set the MAC address in code, it is stored on a sd card. But lately I read a couple of older threads on the forum about the dhcp issues again and I noticed that I never saw setting the mac address in the provided sample code. The MAC address is essential for a DHCP server, so I was thinking if that could be a source of problems?
