Ohh

And thanks for you answer

I just reformatting it, and its a SDHC 8GB - Is that a problem? :/

Hi Chris,

i have tried everything nearly for writing.

  try
  {
  string[] directories = Directory.GetDirectories("");
  string dir = "";
  Debug.Print("Directories count: " + directories.Length);
  for (int i = 0; i < directories.Length; i++)
  {
  Debug.Print("Directory: " + directories[i]);
  if (directories[i].ToLower().IndexOf("sd") >= 0)
  {
  dir = directories[i];
  Debug.Print("Found: " + dir);
  }
  }

  Debug.Print("Finding files");
  string[] files = Directory.GetFiles(dir);
  Debug.Print("File count: " + files.Length);
  for (int i = 0; i < directories.Length; i++)
  {
  Debug.Print("Files: " + files[i]);
  }

  Stream st = new FileStream(dir + @"Log.txt", FileMode.OpenOrCreate);
  }
  catch (Exception ex)
  {
  Debug.Print("Error: " + ex);
  }

And this is the log:

Directories count: 1
Directory: SD
Found: SD
Finding files
A first chance exception of type 'System.NotSupportedException' occurred in Microsoft.SPOT.IO.dll
A first chance exception of type 'System.IO.IOException' occurred in System.IO.dll
Error: System.IO.IOException

Update- I was able to flash with the DFU file, and execute simple programs.  I still have not been able to set the MAC address with the same symptom that I posted in the previous message's screengrab.  

Any suggestions?

Thanks

Have you ever installed the v4.3 framework ? - Because im getting thet error if im using the tool from 4.3 to set mac adresse on a board with 4.2. Use the tool from 4.2 to set the mac address and it should work

You got no error handling in your while loop, so if you get any exception the loop will exit.

Use

try

{

...

}

catch { }
