Version: 4.2.2 (version 4.2.2.0)

This firmware requires use of the .NET Micro Framework v4.2 SDK (QFE2) and Netduino 4.2.2 SDK.

With this firmware, you will have the following resources available for your code:
192KB Flash
60KB RAM

This firmware includes the following updates:
1. Now compatible with legacy SecretLabs AnalogInput and PWM classes (requires 4.2.2 SDK)
2. Bug fix: SPI chip select timing corrected
3. Bug fix: PWM frequency corrected
4. New: more reliable rebooting during deployment

To find the current version of your Netduino firmware:
1. Go to the Start Menu > Programs > Microsoft .NET Micro Framework 4.2 > Tools
2. Run MFDeploy.exe. Be careful to run MFDeploy.exe and not MFDeploy.exe.config (as file extensions are hidden by default)
3. Plug your Netduino into your PC using a Micro USB cable.
4. In the Device section at top, select USB instead of Serial. Your Netduino should appear in the drop-down; if not, select it.
5. Select the Target menu, Device Capabilities option.
6. In the output box, find the "SolutionReleaseInfo.solutionVersion" value. This is your firmware version.

To flash this firmware:
1. Detach your Netduino
2. Press and hold your Netduino's pushbutton while plugging it in via USB; this will put it in bootloader mode.
3. Erase the firmware on your Netduino using the STDFU Tester application
> a. Select the "Protocol" tab
> b. Press the "Create from Map" button
> c. Select the "Erase" radio button option
> d. Press the "Go" button
> e. Wait for erase process to complete
4. Flash the attached .DFU file using the ST DfuSe Demonstrator application (included with STDFU Tester)
> a. Locate the "Upgrade or Verify Action" pane (bottom-right pane)
> b. Press "Choose..." and select the attached DFU file
> c. Check the "Verify after download" option
> d. Press "Upgrade". It will take a few minutes to update your Netduino.
> e. Detach and reattach your Netduino (power cycle) or press "Leave DFU mode"

Enjoy, and please let us know if you run into any troubles.
