Netduino Go Throwing Error After Firmware Update

I just opened my Netduino Go for the first time after it sat on a shelf for several years. The board lights up and visual studio recognizes the board. I downloaded the firmware update utility and chose the “ Beta 1” for Netduino Go. Now I am getting the below error when I try the Blinky code to blink the onboard led.

The thread ‘’ (0x2) has exited with code 0 (0x0).
Exception thrown: ‘System.ArgumentException’ in Microsoft.SPOT.Hardware.dll

An unhandled exception of type ‘System.ArgumentException’ occurred in Microsoft.SPOT.Hardware.dll

The program ‘[4] Micro Framework application: Managed’ has exited with code 0 (0x0).

Also, here is the code I am trying to run targeting the 4.3 framework:
using System;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;

namespace Blinky
public class Program
public static void Main()
// write your code here

        OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);

        while (true)




Another question. If I want to go back to the original firmware how do I do this?

Going back to an earlier firmware should be the same as the upgrade process. I don’t know about the original firmware but you could try the 4.2.2 firmware to see if that helps.


I gave up and purchased a Netduino 3 Wifi
