I think you still may not have the correct firmware. Mine is 4.3.2.1 like the link I posted above.

Hi all,

I know this thread is old, but is there an updated way to perform this exact task?

Right now when I run the sample program given, I get this error:

Inserted
A first chance exception of type 'System.IO.IOException' occurred in Microsoft.SPOT.IO.dll
An unhandled exception of type 'System.IO.IOException' occurred in Microsoft.SPOT.IO.dll


 Uncaught exception

Chris,

Thank you for your reply, and I am looking forward to those updates in the near future!

I had this exact same issue, and I just uninstalled the SDK's, & .NetMF and followed his instructions here to reinstall-> http://forums.netdui...-v432-update-1/

I think I originally had the wrong firmware installed, because I just installed whatever was posted on the main website under downloads

This is how I read from my SD card:
 

        public string GetFileFromSD(string FilePath) {
            var line = "";
            using (FileStream fs2 = new FileStream(FilePath, FileMode.Open, FileAccess.Read, FileShare.None)) {
                using (StreamReader sr = new StreamReader(fs2)) {

                    Debug.Print(line);
                    line = sr.ReadToEnd();
                }
            }
            return line;
        }

FYI: I finally figured out the answer after days of trial and error:

VolumeInfo.GetVolumes()[0].FlushAll();

Yup that's all you have to do. Not sure why it works

So I was able to a write code that gets my IP address from a file and changes it on initialization.

// Get and Update properties from those in the file on the SD
sd.GetAddressesFromFile();
var interf = NetworkInterface.GetAllNetworkInterfaces()[0];
interf.EnableStaticIP(sd.IP, sd.SubnetMask, sd.DefaultGateway);
//Debug print our IP address
Debug.Print(Microsoft.SPOT.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()[0].IPAddress);

And that works great. However when I send a request from my browser to update the IP address, the only way I can get it to actually change is doing a PowerState.RebootDevice();

I was just wondering what dependencies are in the RebootDevice method that cause the IP address to reset. I tried playing around with the ReleaseDhcpLease() and RenewDhcpLease() but they didn't really do anything for me. Here is my code that changes the IP address after I get it from the browser:

        private void UpdateAddressesRequest() {
            // If no values were actually updated, we don't need to run this method.
            if (sd.ChangeFlag == false)
                return;

            var interf = NetworkInterface.GetAllNetworkInterfaces()[0];            
            interf.EnableStaticIP(sd.IP, sd.SubnetMask, sd.DefaultGateway);
            interf.EnableStaticDns(new string[] { "172.16.1.1", "172.16.1.2" });

            sd.ChangeFlag = false;
            PowerState.RebootDevice(soft: false);
        }

This was great and super easy to use! Great job!

Looks cool! Is that a touch screen to play the game?

Hey all,

So I have an issue that has been causing my head to spin when writing to an SD card. I have searched all the threads and couldn't find anything like my issue.

I can read perfectly fine from the SD card, but when writing, it will only write over text that is currently in the file.

            string FilePath = @"\SD\yourfile.txt";

            using (var fs = new FileStream(FilePath, FileMode.OpenOrCreate, FileAccess.Write, FileShare.None, 512))
            using (var sw = new StreamWriter(fs)) {
                sw.WriteLine("Will This String Write?");
                Thread.Sleep(1000);
                sw.WriteLine("done.");
                Thread.Sleep(1000);
                sw.Flush();
            }
            Debug.Print("We did something");

So for example if my text file contains the string "My String" then when I run the above program, the only thing in the text file will be "Will This" instead of the entire string. And if there is nothing in the file at all, then nothing is written. I have the lastest firmware and SDK's. In fact I recently just reinstalled everything. I am also using a 2GB sd card as recommended.

Thanks for your help!

So I ended up reinstalling the firmware, and SDK's and I no longer get the error!

Hi Chris, 

Thank you for getting back to me.

Yes I get it when doing any simple hello world program, so I assume it has something to do with my setup.

I am using a netduino plus 2 and Visual Studios 2013.

Hello all,

I'm new to netduino,

Everytime I try and run any program, I get the following error:

An unhandled exception of type 'System.NotSupportedException' occurred in SecretLabs.NETMF.Hardware.Netduino.dll

I've recopied these dll's into my project folder, and even tried to make a new project and still get the same error.

I fortunately am able to continue through the error, but I'm curious as to what is causing it and how to fix it.

Thanks!
