Wellll, new to netduino and networking... and trying to get netduino+ talking to a server app....
But on netduino all I get are 10053 socket errors.
Since I can't ping to or from netduino, makes it very hard to pursue...
Suggestions?
(ultimate goal is to do http get/post ops from netduino)
How to validate connectivity to ethernet?

Confirm you have received an IP Address - better yet, set your Netduino to a static IP.
Then do a normal GET request, and work from there. There are examples on the forum, and in the SDK.
Start small, and work your way up - I have found that most of my issues have been RAM related.

It's certainly not perfect, but maybe my simple GsiotDiagnostics program helps:
Download page
As Colin said, try it with a static IP address if it doesn't work with DHCP.

We got it working!

You mean your app is too large to run in RAM?
Or ?

I find that when the amount of free RAM gets lower than 32KB, network activity starts to fail more regularly - by no means a scientific measurement, just from observation.

Colin,
How do you measure free RAM?
(Sorry, I am new to all this...)

Hi samjones,
I don't mean to beat Colin to the reply here, but I thought I'd help out...
The following function will force garbage collection and return the amount of free RAM:

Nice, didn't know thatThe following function will force garbage collection and return the amount of free RAM:
int freemem = Debug.GC(true);
@samjones: If you are interested in GET/POST methods to/from Netduino, have a look at my Webserver (look at my signature) or at Stephans HTTP Client http://forums.netdui...0244#entry20244...
I think you can get good ideas by looking at these projects =)
