As you can see, an exception is thrown when invoking Directory.GetFiles() method.
What does 'System.NotSupportedException' mean? Is my SD card not compatible or it is something else?
I have latest version of N+ firmware.


It's probably an incompatible MicroSD card. What size it it?

Also, what brand/model of SD card are you using?

I tried with 1 GB no-name card (got it with mobile phone) and 32 MB SanDisk Transflash card.
I've just done full format of the second one and now it works :)

I am using this firmware: NetduinoPlus_v4.1.1_beta1_CW.NETMF.OneWire- and have the same problem with StreamWriter.
Is the patch included in this firmware?
