Build 2015: Windows 10 IoT Preview on a Raspberry Pi 2

Day 1 of Build 2015 has been great!   The IoT inclusions especially have been very exciting for me.

 

We now have Windows 10 IoT core released and running on:

Raspberry Pi 2
MinnowBoard Max
Galileo

 

Also very interesting and exciting news is, we have Arduino support from Microsoft.

Windows Remote Arduino
Windows Virtual Shields for Arduino

 

Let’s start by installing Windows 10 IoT Core Preview on a Raspberry PI 2. I know many of you that bought a PI just to do this, I know I did. ūüôā

 

Start by downloading the “Windows_IoT_Core_RPI2_BUILD” from https://connect.microsoft.com/windowsembeddedIoT/Downloads. ¬†I had to accept¬†some EULAs and click around before anything appeared to be selected for download. ¬†It could have also been a timing problem as I was a bit eager to download and perhaps it was not available that soon.

 

The requirement for the installation is a Windows 10 Build 10069 or higher PC to copy the Windows 10 IoT installation onto an SD card . I downloaded the new Windows 10 Build 10074 ISO that was released today from http://windows.microsoft.com/en-us/windows/preview-iso-update-1504.

 

Install Windows 10. I ignored the recommendations and installed on a Virtual Machine (on VMWare) and not a physical PC.  VMWare  passes through the SD card without problems to Windows 10.

 

Once everything is installed, copy the “Flash.ffu” file from the downloaded “Windows_IoT_Core_RPI2_BUILD” zip file to a folder on the Windows 10 PC.

 

From an Administrator Command line run the following command:

 

diskpart
list disk
exit

 

Note the number of the disk associated with the SDCard.

 

Run the dism command replacing the N in “\PhysicalDriveN” to the number noted above.

 

dism.exe /Apply-Image /ImageFile:flash.ffu /ApplyDrive:\\.\PhysicalDriveN /SkipPlatformCheck

After a short wait, you should see: “Operation completed successfully”. Eject the SD card.

Insert the SD card into the SD card slot in the Raspberry PI 2. Plug the HDMI cable into the PI and of course the monitor. Plug the power cable into the Raspberry PI. After a few worrying minutes Windows 10 IoT should be all booted up. It will reboot once during the initial setup process and the interesting blocks displayed in-between the Windows Logo appearing and final boot-up seems normal.

 

Next step is to make it do something useful! ūüôā

Running ASP .NET vNext on a pcDuino

Microsoft is doing a lot of great things at the moment.  One of these is the ability to run ASP .NET vNext away from a Windows Server, and away from IIS.    Being a ASP .NET Mvc developer for a few years now, the idea to run on any environment is quite liberating.

 

A pcDuino is a¬†device with tons of potential. ¬† It’s a powerful device and it really is a full “mini PC” with enough processing power to do interesting things like image processing. ¬† ¬†But is small enough to be used in situations where you would uses an Arduino, Netduino, RFduino etc in the IoT or maker space. ¬† The pcDuino¬†also has an Ethernet port and on-board WiFi, so it is a rather compelling internet connected device.

Having deployed Mono on my board already, it was also a no brainer to extend that and to explore the potential of an internet connected device but leveraging ASP .NET vNext to do that.

To get started read these two blog posts:

 

Now that we have both Ubuntu and Mono installed, we can now begin getting ASP .NET vNext up and running.

To figure out how to do this, I referred to the ASP .NET github repository, “Getting Started” page. ¬†This page can be found here:¬†¬†https://github.com/aspnet/Home

 

Lets start by installing the necessary certificates.

$ CERTMGR=/usr/local/bin/certmgr
$ sudo $CERTMGR -ssl -m https://go.microsoft.com
$ sudo $CERTMGR -ssl -m https://nugetgallery.blob.core.windows.net
$ sudo $CERTMGR -ssl -m https://nuget.org
$ sudo $CERTMGR -ssl -m https://www.myget.org/F/aspnetvnext/
$ mozroots --import --sync

 

We need curl, so install that next

$ sudo apt-get install curl

 

Download and execute the KVM installer on the ASP .NET site.   As of writing this,  the master branch has the 1.0.0-beta1, so we will use that.

$ curl https://raw.githubusercontent.com/aspnet/Home/master/kvminstall.sh | sh && source ~/.kre/kvm/kvm.sh
$ kvm upgrade

 

Check to see if the installation is correct, you should see the version number reflected with the list command.

$ kvm list

 

If git is not already installed, install git next.

$ sudo apt-get-install git

 

The web server ASP .NET vNext uses (Kestrel), is based on Libuv, so we need to install that next.

$ git clone https://github.com/libuv/libuv.git
$ cd libuv
$ sh autogen.sh
$ ./configure
$ make
$ make check
$ sudo make install

 

Now we need something to run.  Lets use one of the samples from the ASP .NET github repository.for simplicity.  Clone the aspnet repository.

$ git clone https://github.com/aspnet/Home

 

Focusing on the Mvc example, change to the directory “HelloMvc”. ¬† ¬†To resolve and download the necessary dependencies for the project, execute a restore command on the package manager “KPM”.

$ cd Home/samples/HelloMvc
$ kpm restore

 

We need to set up a symbolic link for libuv to avoid any “Object Reference not set to an instance of an object” errors. ¬† ¬†This is not the most helpful or informative of error messages, but we get what it means.

 $ ln /usr/local/lib/libuv.so -sf ~/.kpm/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-beta1/native/darwin/universal/libuv.dylib

 

Run the Kestrel server

$ LD_LIBRARY_PATH=/usr/local/lib k kestrel

 

If all goes well you should see “Started” appear on the command line.

$ Started

 

The default port for kestrel is 5004. ¬† As a test navigate to “http://localhost:5004” using the internal pcDuino Chromium browser. ¬† ¬† The sample ASP .NET Mvc application should appear as below.

 asp .net vnextAsp .NET Mvc site up and running on Mono 3.12.0

 

Find the ip address of the pcDuino using the ifconfig command.

$ ifconfig

 

Use this ip address from a remote device (or pc’s) browser. ¬†¬†The great feature of the pcDuino that it is equipped with both an Ethernet port and WiFi so connectivity is very easy and convenient.

 

Congratulations you now have a Mono / NET powered IOT device running ASP .Net vNext!   A mobile wireless web server / web connected device has endless potential.   In future blog posts I hope to explore some of those.

 

I hope this was helpful!
