-## How to Edit Docs
-
-### Objective
-
-We will go through the process of downloading existing doccumentation and adding some content to a test document.
-
-### Markdown, MkDocs, Mou
-
-The Mynewt documentation you see on the Apache incubator website is a bunch of HTML files generated using MkDocs which is a simple static site generation tool geared towards building project documentation. You can read about it at [http://www.mkdocs.org](http://www.mkdocs.org). Documentation source files are written in Markdown, and configured with a single YAML configuration file. Markdown is a lightweight markup language with plain text formatting syntax designed so that it can be converted to HTML and many other formats using a tool (which in our case is MkDocs).
-
-You do not need to install MkDocs unless you want to actually render your documentation in HTML in order to preview it before pushing your content to the remote repository. Typically, using a Markdown editor such as [Mou](http://25.io/mou/) is enough to check how it will look after the document has gone through MkDocs. Go ahead and download [Mou](http://25.io/mou/). If you are on a Windows machine, download the [editor of your choice](http://alternativeto.net/software/mou/?platform=windows).
-
-Currently someone in the project is designated to use MkDocs to generate the HTML pages periodically after changes have been reviewed and accepted into the master branch.
-
-
-### Access to the Apache repo
-
-Get an account on Apache. You do not need a committer account to view the website or clone the repository but you need it to push changes to it.
-
-If you are not a committer, you may follow the proposed non-committer workflow to share your work. The direct link to the proposed workflow is [https://git-wip-us.apache.org/docs/workflow.html](https://git-wip-us.apache.org/docs/workflow.html). You will find the steps described in more detail later in this tutorial.
-
-### Making a local copy
-
-* Copy the document source files into a local directory and look at the contents of the copied directory to get an idea of the directory structure. Use http instead of https if you are a non-committer.
-
- $ git clone https://git-wip-us.apache.org/repos/asf/incubator-mynewt-site.git
- Cloning into 'incubator-mynewt-site'...
- remote: Counting objects: 330, done.
- remote: Compressing objects: 100% (263/263), done.
- remote: Total 330 (delta 120), reused 0 (delta 0)
- Receiving objects: 100% (330/330), 4.34 MiB | 830.00 KiB/s, done.
- Resolving deltas: 100% (120/120), done.
- Checking connectivity... done.
- $ ls
- incubator-mynewt-site
- $ ls incubator-mynewt-site/
- docs images mkdocs.yml
-
-* Create a new branch to work on your documentation and move to that branch.
-
- $ git checkout -b <your-branch-name>
-
-
-### File to be edited
-
-The file you will edit is [try_markdown.md](./try_markdown.md).
-
-### Editing an existing page
-
-* Open the application Mou.
-
-* Open the file incubator-mynewt-site/docs/chapter1/try_markdown.md in Mou.
-
-* Edit the last item on the list.
-
-* Save and quit the application.
-
-You may want to review the documentation organization back in [Home](../index.md) to remind you how to locate files easily. The corresponding directory tree structure is shown below.

-
-### Adding a new page
-
-If you create a new file somewhere in the `docs` subdirectory to add a new page, you have to add a line in the `mkdocs.yml` file at the correct level. For example, if you add a new module named "Ethernet" by creating a new file named `ethernet.md` in the chapter5 subdirectory, you have to insert the following line under `Modules:` in the `mkdocs.yml` file.
-
- - 'Ethernet': 'chapter5/ethernet.md'
-
-### Pushing changes to remote as a committer
-
-If you are not a committer yet, skip this section and proceed to the [next section](#sharing-changes-as-a-non-committer).
-
-* Check whether your remote git repository is set up. If you see the remote location as shown below you can skip the next step.
-
- $ git remote -v
- origin https://git-wip-us.apache.org/repos/asf/incubator-mynewt-site.git (fetch)
- origin https://git-wip-us.apache.org/repos/asf/incubator-mynewt-site.git (push)
-
-* If, however, you do not see your remote repository, then set it up as follows.
-
-
- $ git remote add origin https://git-wip-us.apache.org/repos/asf/incubator-mynewt-site.git
-
-* First check the git status. It will show you that the `try_markdown.md` document has been modified. So you will stage a commit, and then commit the change. Finally, you will push the changes to the remote repository.
-
- During staging below using `git add`, we use the `-A` option indicating you want to stage all your modifications. Instead, you can choose to specify only the files that you want to. The commit message (specified after `-m`) should summarize what your changes are about.
-
- $ git status
- $ git add -A
- $ git commit -m "My first doc change as a trial run"
- $ git push -u origin <your-branch-name>
-
-* You can see the changed Markdown file if you traverse the tree on the git repository [ https://git-wip-us.apache.org/repos/asf/incubator-mynewt-site.git]( https://git-wip-us.apache.org/repos/asf/incubator-mynewt-site.git).
-
-* A commit notification automatically goes out to the commits@mynewt.incubator.apache.org mailing list. The "upstream" manager pulls the notified changes, reviews it, and merges it to the master branch if all is well. Otherwise you get an email for further changes.
-
-### Sharing changes as a non-committer
-
-We suggest you follow the proposed non-committer workflow at Apache to share your work. The direct link to the proposed workflow is [https://git-wip-us.apache.org/docs/workflow.html](https://git-wip-us.apache.org/docs/workflow.html).
-
-* Assuming you have made changes to the example file, you will first commit your changes.
-
- $ git add -A
- $ git commit -m "My first doc change as a trial run"
-
-* Once you're ready to share your changes with the rest of the project team, you can use the git format-patch command to produce a patch file (or a nice set of patches in the future):
-
- $ git format-patch origin/trunk
-
-* Email the patch file to dev@mynewt.incubator.apache.org. Later on you may attach multiple files in your email to the mailing list as part of an existing thread or a new one. Remember to summarize the issue you have tackled and your work if the commit message is not detailed enough.
-
- If there is a JIRA ticket associated with your work you should post your patch files to the ticket.
-
-
-### Conversion to HTML
-
-The conversion of the Markdown files to HTML for the website happens manually and statically using MkDocs. You cannot see automatic and immediate rendering in HTML upon making a change in the Markdown file. You can choose to stop here and proceed to changing other Markdown files in your branch.
-
-### Local preview of HTML files
-
-However, you have the option to download MkDocs and do a local conversion yourself to preview the pages using the built-in devserver that comes with MkDocs. But first you will have to install MkDocs for that. In order to install MkDocs you'll need Python installed on your system, as well as the Python package manager, pip. You can check if you have them already (usually you will).
-
- $ python --version
- Python 2.7.2
- $ pip --version
- pip 1.5.2
- $ pip install mkdocs
-
-You will then run the built-in webserver from the root of the documentation directory using the command `mkdocs serve`. The root directory for documentation is `incubator-mynewt-site` or the directory with the `mkdocs.yml` file.
-
- $ ls
- docs images mkdocs.yml
- $ mkdocs serve
-
-Then go to [http://127.0.0.1:8000](http://127.0.0.1:8000) to preview your pages and see how they will look on the website! Remember that the Myself website itself will not be updated.
-
-For more information on MkDocs go to [http://www.mkdocs.org](http://www.mkdocs.org).

-## Newt Concepts
-
-This page introduces the basic terms you will need to find your way around the Mynewt ecosystem.
-
-### Basic components in the ecosystem
-
-* NewtOS is an open-source RTOS (Real Time Operating System) that works on a variety of hardware. The goal is to develop a pre-emptive, multitasking OS that is highly modular, making it possible to mix and match components to enable desired features and capabilities on multiple hardware architectures. Examples of components being worked on are the Core RTOS, a flash file system, utility functions, a variety of board support packages, packages of microcontrollers etc.
-
-
-* Network protocol stacks such as Bluetooth Low Energy, and more
-
-
-* Newt Tool helps you mix the specific packages for the combination of hardware and low-level embedded architecture features of the user's choice and generate the corresponding run-time image based on the NewtOS. It provides the infrastructure to manage and build for different CPU architectures, memory units, board support packages etc., allowing a user to formulate the contents according to the low-level features needed by his or her project.
-
-
-### Terminology
-
-A Mynewt user starts with a project in mind that defines the application or utility that he or she wants to implement on an embedded device. Making an LED blink on an electronics prototyping board is a common starter project. Enabling a BLE (Bluetooth Low Energy) peripheral mode on a development board is a more complex project. Specifying a project requires naming it, at the very least, and then adding the desired properties or attributes. In order to actualize a project, it needs to be applied to a target which is essentially a combination of some specified hardware and the execution environment.
-
-In the mynewt lifecycle, a project grows in a nest. A nest may house multiple projects. The nest is, therefore, a repository where various component packages for one or more projects reside. Each package is an egg (naturally!). However, in the world of Mynewt an egg may consist of other eggs! For example, the starter project Blinky is an egg consisting of several constituent eggs that enable core features. The egg form is suitable for elemental units of code as it explicitly exposes characteristics such as dependencies, versions, capabilities, requirements etc., thus making assembling appropriate components for a project and building an image for it easy to follow, modular, and robust.
-
-A nest can be given any name. For example, you will see a nest named "tadpole" in Mynewt ([https://git-wip-us.apache.org/repos/asf?p=incubator-mynewt-tadpole.git](https://git-wip-us.apache.org/repos/asf?p=incubator-mynewt-tadpole.git)). It contains all the core libraries of the operating system for the native platform which currently supports compilation on Mac OS X. The core libraries are contained in the form of eggs where an egg is a basic unit of implementation of any aspect of the RTOS. The eggs are distributed in the following directory structure inside the nest:
-
-* libs: contains the two eggs `os` and `testutil`
-* hw: contains three eggs - (i) `hal` which has the abstraction layer (HAL) API definitions that all BSP and MCU implementations must support, (ii) `/mcu/native` which in an MCU implementation for the native platform (a simulator, in this case), and (iii) `bsp/native` which is a BSP implementation for the native platform
-* compiler: contains the `sim` egg which bundles the compiler specifications for the native platform.
-
-Let's explore this sample nest a bit further. The `libs/os` egg contains code for scheduler, process/thread/memory management, semaphores etc. It is the core RTOS which ports to all supported chip platforms.The `libs/testutil` egg contains code for testing packages on hardware or simulated environment. The `hw/hal` egg contains header files that provide abstraction for physical hardware components such as GPIO (general purpose input/output), network adapters, timers, and UARTs. This `hw/hal` egg is an MCU peripheral abstraction designed to make it easy to port to different MCUs (microcontrollers). The `hw/mcu/native` egg contains code for microcontroller operations on the native platform. The `hw/bsp/native` egg contains the board support package for the native platform. And finally, the sixth egg `sim` contains the compiler specifications such as path and flags. Currently the compilation is supported on Mac OS X.
-
-You can see another nest in the mynewt ecosystem called the "larva". It was spawned from the skeletal "tadpole" nest using the newt tool. Spawning is easy - ` $ newt create nest <your_nest_name> `. "larva" is the developer's test repository containing all sorts of eggs being written and incubated, including ones to enhance the core operating system which should eventually make their way into the "tadpole" nest. There is a `hatch_tadpole` script to update the "tadpole" nest when the core OS related eggs in "larva" are ready.
-
-There is a third nest named "newt" that contains all the eggs needed to support the build and release process of mynewt software. In the future, there will also be pre-built nests for certain common hardware devices to enable a user to quickly get started with a project.
-
-
-### A Mynewt contributor
-
-A contributor can choose to work on any area(s) of the Mynewt endeavor that appeals to him or her. Hence, you can work on one or more eggs or an entire nest. You can create your own nest (master) or create a branch in an existing nest. For now, Runtime contributors will review any new areas of support that you may wish to introduce e.g. a new board support package (BSP) or a new network protocol.
-
-A contributer role necessarily implies he or she is a Mynewt user (see below) of some or all of the products developed.
-
-### A Mynewt user
-
-An application developer is interested only in using software available in this ecosystem to build a top level build artifact. He or she may either:
-
-* Use a pre-built nest, or
-* Spawn a new nest using the newt tool for a target where a target is a custom combination of supported hardware components
-
-In either case, the user would use the newt tool to create and set the target in the chosen nest. The newt tool would then be used to build out the target profile which would determine which eggs to choose. Finally, the user would use the newt tool to generate a run-time image that can be run on the device.

-## Blinky, the First Project
-
-### Objective
-
-We will show you how you can use eggs from a nest on Mynewt to make an LED on a target board blink. We will call it ** Project Blinky**. The goals of this tutorial are threefold:
-
-1. First, you will learn how to set up your environment to be ready to use Mynewt OS and newt tool.
-2. Second, we will walk you through a download of eggs for building and testing [on a simulated target](#building-test-code-on-simulator).
-3. Third, you will download eggs and use tools to create a runtime image for a board to make its LED blink. You have two choices here - you can [download an image to SRAM](#using-sram-to-make-led-blink) or you can [download it to flash](#using-flash-to-make-led-blink).
-
-** Time Requirement**: Allow yourself a couple of hours for this project if you are relatively new to embedded systems and playing with development boards. Those jumpers can be pesky!
-
-
-### What you need
-
-1. STM32-E407 development board from Olimex. You can order it from [http://www.mouser.com](http://www.mouser.com/ProductDetail/Olimex-Ltd/STM32-E407/?qs=UN6GZl1KCcit6Ye0xmPO4A%3D%3D), [http://www.digikey.com](http://www.digikey.com/product-detail/en/STM32-E407/1188-1093-ND/3726951), and other places.
-2. ARM-USB-TINY-H connector with JTAG interface for debugging ARM microcontrollers (comes with the ribbon cable to hook up to the board)
-3. USB A-B type cable to connect the debugger to your personal computer
-4. Personal Computer
-
-The instructions assume the user is using a Bourne-compatible shell (e.g. bash or zsh) on your computer. The given instructions have been tested with the following releases of operating systems:
-
-* Mac: OS X Yosemite Version 10.10.5
-* Linux: Ubuntu 14.10 (Utopic Unicorn)
-* Windows: Windows 10
-
-
-### Access to the Apache repo
-
-* Get an account on Apache. You do not need a committer account to view the website or clone the repository but you need it to push changes to it.
-
-* The latest codebase for the Mynewt OS is on the master branch at https://git-wip-us.apache.org/repos/asf/incubator-mynewt-larva.git
-
-* The latest codebase for the Newt tool is on the master branch at https://git-wip-us.apache.org/repos/asf/incubator-mynewt-newt.git
-
-The following shows how to clone a Mynewt OS code repository:
-
-* Non Committers
-
- $ git clone http://git-wip-us.apache.org/repos/asf/incubator-mynewt-larva.git
-
-* Committers
-
- $ git clone https://git-wip-us.apache.org/repos/asf/incubator-mynewt-larva.git
-
-
-
-### Getting your Mac Ready
-
-#### Installing Homebrew to ease installs on OS X
-
-* Do you have Homebrew? If not, open a terminal on your Mac and paste the following at a Terminal prompt. It will ask you for your sudo password.
-
- $ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-
- Alternatively, you can just extract (or `git clone`) Homebrew and install it to `/usr/local`.
-
-#### Installing Go
-
-* The directory structure must be first readied for using Go. Go code must be kept inside a workspace. A workspace is a directory hierarchy with three directories at its root:
-
- * src contains Go source files organized into packages (one package per directory),
-
- * pkg contains package objects, and
-
- * bin contains executable commands.
-
- The GOPATH environment variable specifies the location of your workspace. First create a 'dev' directory and then a 'go' directory under it. Set the GOPATH environment variable to this directory where you will soon clone the newt tool repository.
-
- $ cd $HOME
- $ mkdir -p dev/go
- $ cd dev/go
- $ export GOPATH=`pwd`
-
- Note that you need to add export statements to ~/.bash_profile to export variables permanently. Don't forget to source the file for the change to go into effect.
-
- $ vi ~/.bash_profile
- $ source ~/.bash_profile
-
-* Next you will use Homebrew to install Go. The summary message at the end of the installation should indicate that it is installed in the /usr/local/Cellar/go/ directory. You will use the Go command 'install' to compile and install packages (called eggs in the Mynewt world) and dependencies.
-
- $ brew install go
- ==>
- ...
- ...
- ==> *Summary*

-
- Alternatively, you can download the Go package directly from (https://golang.org/dl/) instead of brewing it. Install it in /usr/local directory.
-
-
-#### Creating local repository
-
-* You are ready to download the newt tool repository. You will use Go to copy the directory (currently the asf incubator directory). Be patient as it may take a minute or two. Check the directories installed.
-
- $ go get git-wip-us.apache.org/repos/asf/incubator-mynewt-newt.git/newt
- $ ls
- bin pkg src
- $ ls src
- git-wip-us.apache.org github.com gopkg.in
-
-
-* Check that newt.go is in place.
-
- $ ls $GOPATH/src/git-wip-us.apache.org/repos/asf/incubator-mynewt-newt.git/newt
- Godeps README.md coding_style.txt newt.go
- LICENSE cli design.txt
-
-
-#### Building the Newt tool
-
-* You will use Go to run the newt.go program to build the newt tool. The command used is `go install` which compiles and writes the resulting executable to an output file named `newt`. It installs the results along with its dependencies in $GOPATH/bin.
-
- $ cd $GOPATH/src/git-wip-us.apache.org/repos/asf/incubator-mynewt-newt.git/newt
- $ go install
- $ ls "$GOPATH"/bin/
- godep incubator-mynewt-newt.git newt
-
-* Try running newt using the compiled binary. For example, check for the version number by typing 'newt version'. See all the possible commands available to a user of newt by typing 'newt -h'.
-
- Note: If you are going to be be modifying the newt tool itself often and wish to compile the program every time you call it, you may want to store the command in a variable in your .bash_profile. So type in `export newt="go run $GOPATH/src/git-wip-us.apache.org/repos/asf/incubator-mynewt-newt.git/newt/newt/go"` in your .bash_profile and execute it by calling `$newt` at the prompt instead of `newt`. Here, you use `go run` which runs the compiled binary directly without producing an executable. Don't forget to reload the updated bash profile by typing `source ~/.bash_profile` at the prompt!

-
-* Without creating a project repository you can't do a whole lot with the Newt tool. So you'll have to wait till you have downloaded a nest to try out the tool.
-
-#### Getting the debugger ready
-
-* Before you start building nests and hatching eggs, you need to do one final step in the environment preparation - install gcc / libc that can produce 32-bit executables. So, first install gcc. You will see the brew steps and a final summary confirming install.
-
- $ brew install gcc

-* ARM maintains a pre-built GNU toolchain with a GCC source branch targeted at Embedded ARM Processors namely Cortex-R/Cortex-M processor families. Install the PX4 Toolchain and check the version installed. Make sure that the symbolic link installed by Homebrew points to the correct version of the debugger. If not, you can either change the symbolic link using the "ln -f -s" command or just go ahead and try with the version it points to!

-
-* You have to install OpenOCD (Open On-Chip Debugger) which is an open-source software that will allow you to interface with the JTAG debug connector/adaptor for the Olimex board. It lets you program, debug, and test embedded target devices which, in this case, is the Olimex board. Use brew to install it. Brew adds a simlink /usr/local/bin/openocd to the openocd directory in the Cellar. For more on OpenOCD go to [http://openocd.org](http://openocd.org).

-
-### Getting your Ubuntu machine Ready
-
-
-#### Installing some prerequisites
-
-* Install git, libcurl, and the Go language if you do not have them already.
-
- $ sudo apt-get install git
- $ sudo apt-get install libcurl4-gnutls-dev
- $ sudo apt-get install golang
-
-#### Creating local repository
-
-* The directory structure must be first readied for using Go. Go code must be kept inside a workspace. A workspace is a directory hierarchy with three directories at its root:
-
- * src contains Go source files organized into packages (one package per directory),
-
- * pkg contains package objects, and
-
- * bin contains executable commands.
-
- The GOPATH environment variable specifies the location of your workspace. First create a 'dev' directory and then a 'go' directory under it. Set the GOPATH environment variable to this directory where you will soon clone the newt tool repository.
-
- $ cd $HOME
- $ mkdir -p dev/go
- $ cd dev/go
- $ export GOPATH=$PWD
-
- Note that you need to add export statements to ~/.bashrc (or equivalent) to export variables permanently.
-
-* You are ready to download the newt tool repository. You will use Go to copy the directory (currently the asf incubator directory). Be patient as it may take a minute or two. Check the directories installed.
-
- $ go get git-wip-us.apache.org/repos/asf/incubator-mynewt-newt.git/newt
- $ ls
- bin pkg src
- $ ls src
- git-wip-us.apache.org github.com gopkg.in
-
-
-* Check that newt is in place.
-
- $ ls $GOPATH/src/git-wip-us.apache.org/repos/asf/incubator-mynewt-newt.git/newt
- Godeps README.md coding_style.txt newt.go

- godep incubator-mynewt-newt.git newt
-
-* Try running newt using the compiled binary. For example, check for the version number by typing 'newt version'. See all the possible commands available to a user of newt by typing 'newt -h'.
-
- Note: If you are going to be be modifying the newt tool itself often and wish to compile the program every time you call it, you may want to store the command in a variable in your .bash_profile. So type in `export newt="go run $GOPATH/src/git-wip-us.apache.org/repos/asf/incubator-mynewt-newt.git/newt/newt/go"` in your ~/.bashrc (or equivalent) and execute it by calling `$newt` at the prompt instead of `newt`.

-
-#### Getting the debugger ready
-
-* Before you start building nests and hatching eggs, you need to do one final step in the environment preparation - install gcc / libc that can produce 32-bit executables. You can install these as follows:
-
- $ sudo apt-get install gcc-multilib libc6-i386
-
-* For the LED project on the Olimex hardware, you have to install gcc for AM 4.9.3. This package can be installed with apt-get as documented below. The steps are explained in depth at [https://launchpad.net/~terry.guo/+archive/ubuntu/gcc-arm-embedded](https://launchpad.net/~terry.guo/+archive/ubuntu/gcc-arm-embedded).
-
- $ sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi
- $ sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
- $ sudo apt-get update
- $ sudo apt-get install gcc-arm-none-eabi
-
-* And finally, you have to install OpenOCD (Open On-Chip Debugger) which is an open-source software that will allow you to interface with the JTAG debug connector/adaptor for the Olimex board. It lets you program, debug, and test embedded target devices which, in this case, is the Olimex board. You have to acquire OpenOCD 0.8.0.
-
- If you are running Ubuntu 15.x, then you are in luck and you can simply run:
-
- $ sudo apt-get install openocd
-
- Other versions of Ubuntu may not have the correct version of openocd available. In this case, you should download the openocd 0.8.0 package from [https://launchpad.net/ubuntu/vivid/+source/openocd](https://launchpad.net/ubuntu/vivid/+source/openocd). The direct link to the amd64 build is [http://launchpadlibrarian.net/188260097/openocd_0.8.0-4_amd64.deb](http://launchpadlibrarian.net/188260097/openocd_0.8.0-4_amd64.deb).
-
-* Proceed to the [Building test code on simulator](#building-test-code-on-simulator) section.
-
-### Getting your Windows machine ready for simulated target
-
-The `newt` tool is the build software used to build Mynewt OS images or executables for any embedded hardware device/board, including the one for the current tutorial (STM32-E407 development board from Olimex). You can run the `newt` tool natively on a computer running any of the three Operating System machines - OSX, Linux, or Windows.
-
-However, Mynewt OS images for a simulated target are built on the Windows machine by using Linux versions of the build software (newt)in a virtual machine on your Windows box. The Linux VM is set up by installing the Docker Toolbox. Your Windows machine will communicate with the Linux VM via transient ssh connections. You will then download a Docker image (`newtvm.exe`)that allows you to run the newt commands in the Linux Docker instance. The Docker image contains:
-
- * The newt command-line tool
- * Go
- * A multilib-capable native gcc / glibc
- * An arm-none-eabi gcc
- * Native gdb
-
- The sequence of events when using the Docker image is as follows:
-
- 1. A new docker environment is created in the Linux VM.
- 2. The specified command with the newtvm prefix (`newtvm newt` command) is sent to the docker environment via ssh.
- 3. The Linux command runs.
- 4. The output from the command is sent back to Windows via ssh.
- 5. The output is displayed in the Windows command prompt.
-
-
-#### Install Linux virtual machine
-
-* Download the Docker Toolbox for Windows (version 1.9.0c or later) from [https://www.docker.com/docker-toolbox](https://www.docker.com/docker-toolbox). The Docker toolbox creates a consistently reproducible and self-contained environment in Linux.
-
-* Run the Docker Toolbox installer. All the default settings are OK.
-
-* You may need to add "C:\Program Files\Git\usr\bin" to your PATH
-environment variable. To add to the PATH environment variable, right-click on the Start button in the bottom left corner. Choose System -> Advanced system settings -> Environment Variables. Click on the PATH variable under "System variables" and click Edit to check and add it if it is not already there.
-
-#### Install newtvm tool
-
-* From your base user (home) directory, pull or clone the latest code from the newt repository into the `newt` directory. It includes the executable `newtvm.exe` for the newtvm tool in the `newtvm` directory.
-
- C:\Users\admin> git clone https://git-wip-us.apache.org/repos/asf/incubator-mynewt-newt newt
-
- The newtvm tool is what allows you to run programs in the Linux docker
-instance.
-
-* Run the Docker Quickstart Terminal application inside the Docker folder under Programs. You can find it by clicking Start button -> All apps. By default, the Docker Toolbox installer creates a shortcut to this program on your desktop. Wait until you see an ASCII art whale displayed in the terminal window and the Docker prompt given.

- $
-
- The first time you run this, it may take several minutes to complete. You will need to run the Docker Quickstart Terminal once each time you
-restart your computer.
-
-* Open a command prompt (e.g., Windows-R, "cmd", enter). You execute the newt tool commands as though you were running newt in Linux, but you prefix each command with "newtvm". For example:
-
- C:\Users\admin\newt\newtvm> newtvm newt help
-
-
- The newtvm tool will take a long time to run the first time you execute
-it. The delay is due to the fact that the tool must download the mynewt
-docker instance.
-
-* You are now ready to proceed to [building the image for the simulated target](#building test code on simulator).
-
-
-### Getting your Windows machine ready for hardware target
-
-When you want to produce images for actual hardware board on your Windows machine, go through the following setup procedure and then proceed to the [blinky project on the Olimex board](#Using-SRAM-to-make-LED-blink) with this method.
-
-#### Installing some prerequisites
-
-* You have to install the following if you do not have them already. The steps below indicate specific folders where each of these programs should be installed. You can choose different locations, but the remainder of this
-tutorial for a Windows machine assumes the specified folders.

-
- - Go
-
- Download the release for Microsoft Windows from [https://golang.org/dl/](https://golang.org/dl/) and install it "C:\Go".
-
-
-#### Creating local repository
-
-* The directory structure must be first readied for using Go. Go code must be kept inside a workspace. A workspace is a directory hierarchy with three directories at its root:
-
- * src contains Go source files organized into packages (one package per directory),
-
- * pkg contains package objects, and
-
- * bin contains executable commands.
-
- The GOPATH environment variable specifies the location of your workspace. First create a 'dev' directory and then a 'go' directory under it. Set the GOPATH environment variable to this directory and then proceed to create the directory for cloning the newt tool repository.
-
- $ cd c:\
- $ mkdir dev\go
- $ cd dev\go
-
-* Set the following user environment variables using the steps outlined here.
-
- * GOPATH: C:\dev\go
- * PATH: C:\Program Files (x86)\GNU Tools ARM Embedded\4.9 2015q3\bin;%GOPATH%\bin;C:\win-builds-x86_64\bin;C:\win-builds-i686\bin;C:\msys\bin
-
- Steps:
-
- 1. Right-click the start button
- 2. Click "Control panel"
- 3. Click "System and Security"
- 4. Click "System"
- 5. Click "Advanced system settings" in the left panel
- 6. Click the "Envoronment Variables..." button
- 7. There will be two sets of environment variables: user variables
- in the upper half of the screen, and system variables in the lower
- half. Configuring the user variables is recommended and tested
- (though system variables will work as well).
-
-
-* Next, install godep. Note that the following command produces no output.
-
- $ go get github.com/tools/godep
-
-* Set up the repository for the package building tool "newt" on your local machine. First create the appropriate directory for it and then clone the newt tool repository from the online apache repository (or its github.com mirror) into this newly created directory. Check the contents of the directory.
-
- $ go get git-wip-us.apache.org/repos/asf/incubator-mynewt-newt.git/newt
- $ dir
- bin pkg src
- $ dir src
- git-wip-us.apache.org github.com gopkg.in
- $ dir

-#### Building the newt tool
-
-* * You will use Go to run the newt.go program to build the newt tool. The command used is `go install` which compiles and writes the resulting executable to an output file named `newt`. It installs the results along with its dependencies in $GOPATH/bin.
-
- $ go install

-
-* Try running newt using the compiled binary. For example, check for the version number by typing 'newt version'. See all the possible commands available to a user of newt by typing 'newt -h'.
-
- Note: If you are going to be be modifying the newt tool itself often and wish to compile the program every time you call it, you may want to define the newt environment variable that allows you to execute the command via `%newt%`. Use `set newt=go run %GOPATH%\src\github.com\mynewt\newt\newt.go` or set it from the GUI. Here, you use `go run` which runs the compiled binary directly without producing an executable.

-
-* Without creating a project repository you can't do a whole lot with the Newt tool. So you'll have to wait till you have downloaded a nest to try out the tool.
-
-#### Getting the debugger ready
-
-* Use Zadig to configure the USB driver for your Olimex debugger. If your debugger is already set up, you can skip this step.
-
- 1. Plug in your Olimex debugger.
- 2. Start Zadig.
- 3. Check the Options -> List All Devices checkbox.
- 4. Select "Olimex OpenOCD JTAG ARM-USB-TINY-H" in the dropdown menu.
- 5. Select the "WinUSB" driver.
- 6. Click the "Install Driver" button.
-
-* Proceed to the section on how to [make an LED blink](#making-an-led-blink-from-sram) section.
-
-
-### Building test code on simulator
-
-Note: On a Windows computer, the simulator can be run only in a Linux virtual environment. Make sure you have installed the Docker instance as outlined in [an earlier section](#Getting your Windows machine Ready for simulated target). Consequently, all `newt` commands must be prefaced with `newtvm`.
-
-1. First, you have to create a repository for the project i.e. build your first nest! Go to ~/dev (or your base user directory on a Windows machine)and clone the larva repository from the apache git repository into a local directory named `larva`.
-
- Substitute DOS commands for Unix commands as necessary in the following steps if your machine is running Windows. The newt tool commands do not change.
-
-
- $ cd ~/dev
- $ git clone https://git-wip-us.apache.org/repos/asf/incubator-mynewt-larva.git larva
- $ ls
- go larva
- $ cd larva
- $ ls
- LICENSE clutch.yml hw nest.yml project
- README.md compiler libs net scripts
-
- On Windows, open a command prompt (e.g., Windows-R, "cmd", enter) and work from your home directory:
-
- C:\Users\admin> git clone https://git-wip-us.apache.org/repos/asf/incubator-mynewt-larva.git larva
- C:\Users\admin> cd larva
- C:\Users\admin\larva> dir
- Volume in drive C is Windows

-2. You will now create a new target using the newt tool. You can either use the compiled binary `newt` or run the newt.go program using `$newt` (assuming you have stored the command in a variable in your .bash_profile or .bashrc). When you do a `newt target show` or `$newt target show` it should list all the projects you have created so far.
-
- $ newt target create sim_test
- Creating target sim_test
- Target sim_test sucessfully created!
- $ newt target show
- sim_test
- name: sim_test
- arch: sim
-
- Remember, on a Windows machine you will have to preface `newt` with `newtvm`!
-
- C:\Users\admin\larva>newtvm newt target create sim_test
-
-3. Now continue to populate and build out the sim project.
-
- $ newt target set sim_test project=test
- Target sim_test successfully set project to test
- $ newt target set sim_test compiler_def=debug
- Target sim_test successfully set compiler_def to debug
- $ newt target set sim_test bsp=hw/bsp/native
- Target sim_test successfully set bsp to hw/bsp/native
- $ newt target set sim_test compiler=sim
- Target sim_test successfully set compiler to sim
- $ newt target show sim_test
- sim_test
- arch: sim
- project: test
- compiler_def: debug
- bsp: hw/bsp/native
- compiler: sim
- name: sim_test
-
- Again remember to preface `newt` with `newtvm`on a Windows machine as shown below. Continue to fill out all the project attributes.
-
- C:\Users\admin\larva>newtvm newt target set sim_test project=test
- Target sim_test successfully set project to test
-
-4. Configure newt to use the gnu build tools native to OS X or linux. In order for sim to work properly, it needs to be using 32-bit gcc (gcc-5). Replace
-~/dev/larva/compiler/sim/compiler.yml with the compiler/sim/osx-compiler.yml or linux-compiler.yml file, depending on the system. On a Windows machine follow the instruction for the Linux machine as you are running commands in a Linux VM.
-
- For a Mac OS X environment:
-
- $ cp compiler/sim/osx-compiler.yml compiler/sim/compiler.yml
-
- For a Linux machine:
-
- $ cp compiler/sim/linux-compiler.yml compiler/sim/compiler.yml
-
-5. Next, create (hatch!) the eggs for this project using the newt tool - basically, build the packages for it. You can specify the VERBOSE option if you want to see the gory details. Always remember to preface `newt` with `newtvm`on a Windows machine.
-
- $ newt target build sim_test
- Successfully run!
-
- You can specify the VERBOSE option if you want to see the gory details.
-
- $newt -l VERBOSE target build sim_test

-### Using SRAM to make LED blink
-
-You are here because you want to build an image to be run from internal SRAM on the Olimex board.
-
-#### Preparing the Software
-
-1. Make sure the PATH environment variable includes the $HOME/dev/go/bin directory (or C:\%GOPATH%\bin on Windows machine).
-
- Substitute DOS commands for Unix commands as necessary in the following steps if your machine is running Windows (e.g. `cd dev\go` instead of `cd dev/go`). The newt tool commands do not change.
-
-
-2. If you have cloned the larva repository for the simulator test in the previous section you can skip this step. Otherwise, you have to create a repository for the project i.e. build your first nest! Go to ~/dev and clone the larva repository from the apache git repository into a local directory named `larva`.
-
- Substitute DOS commands for Unix commands as necessary in the following steps if your machine is running Windows. The newt tool commands do not change.
-
- $ cd ~/dev
- $ git clone https://git-wip-us.apache.org/repos/asf/incubator-mynewt-larva.git larva
- $ ls
- go larva
- $ cd larva
- $ ls
- LICENSE clutch.yml hw nest.yml project
- README.md compiler libs net scripts
-
-3. You first have to create a repository for the project. Go to the ~dev/larva directory and build out a second project inside larva. The project name is "blinky", in keeping with the objective. Starting with the target name, you have to specify the different aspects of the project to pull the appropriate eggs and build the right package for the board. In this case that means setting the architecture (arch), compiler, board support package (bsp), project, and compiler mode.
-
-Remember to prefix each command with "newtvm" if you are executing the newt command in a Linux virtual machine on your Windows box!
-
-
- $ newt target create blinky
- Creating target blinky
- Target blinky sucessfully created!
- $ newt target set blinky arch=cortex_m4
- Target blinky successfully set arch to arm
- $ newt target set blinky compiler=arm-none-eabi-m4
- Target blinky successfully set compiler to arm-none-eabi-m4
- $ newt target set blinky project=blinky
- Target blinky successfully set project to blinky
- $ newt target set blinky compiler_def=debug
- Target blinky successfully set compiler_def to debug
- $ newt target set blinky bsp=hw/bsp/olimex_stm32-e407_devboard
- Target blinky successfully set bsp to hw/bsp/olimex_stm32-e407_devboard
- $ newt target show blinky
- blinky
- compiler: arm-none-eabi-m4
- project: blinky
- compiler_def: debug
- bsp: hw/bsp/olimex_stm32-e407_devboard
- name: blinky
- arch: cortex_m4
-
-4. Now you have to build the image. The linker script within the `hw/bsp/olimex_stm32-e407_devboard` egg builds an image for flash memory by default. Since you want an image for the SRAM, you need to switch that script with `run_from_sram.ld` in order to get the egg to produce an image for SRAM. <font color="red"> We are working on making it easier to specify where the executable will be run from for a particular project and automatically choose the correct linker scripts and generate the appropriate image. It will be specified as a project identity e.g. bootloader, RAM, flash (default) and the target will build accordingly. </font>.
-
- Once the target is built, you can find the executable "blinky.elf" in the project directory at ~/dev/larva/project/blinky/bin/blinky. It's a good idea to take a little time to understand the directory structure.
-
- $ cd ~/dev/larva/hw/bsp/olimex_stm32-e407_devboard
- $ diff olimex_stm32-e407_devboard.ld run_from_sram.ld
- $ cp run_from_sram.ld olimex_stm32-e407_devboard.ld
- $ cd ~/dev/larva/project/blinky/bin/blinky
- $ newt target build blinky
- Building target blinky (project = blinky)
- Compiling case.c
- Compiling suite.c
- ...
- Successfully run!
- $ ls
- LICENSE clutch.yml hw nest.yml project
- README.md compiler libs net scripts
- $ cd project
- $ ls
- bin2img bletest blinky boot ffs2native test
- $ cd blinky
- $ ls
- bin blinky.yml egg.yml src
- $ cd bin
- $ ls
- blinky
- $ cd blinky
- $ ls
- blinky.elf blinky.elf.bin blinky.elf.cmd blinky.elf.lst blinky.elf.map
-
-
-5. Check that you have all the scripts needed to get OpenOCD up and talking with the project's specific hardware. Depending on your system (Ubuntu, Windows) you may already have the scripts in your `/usr/share/openocd/scripts/ ` directory as they may have been part of the openocd download. If yes, you are all set and can proceed to preparing the hardware.
-
- Otherwise check the `~/dev/larva/hw/bsp/olimex_stm32-e407_devboard` directory for a file named `f407.cfg`. That is the config we will use to talk to this specific hardware using OpenOCD. You are all set if you see it.
-
- $ ls ~/dev/larva/hw/bsp/olimex_stm32-e407_devboard
- bin olimex_stm32-e407_devboard_debug.sh
- boot-olimex_stm32-e407_devboard.ld olimex_stm32-e407_devboard_download.sh
- egg.yml run_from_flash.ld
- f407.cfg run_from_loader.ld
- include run_from_sram.ld
- olimex_stm32-e407_devboard.ld src
-
-
-#### Preparing the hardware to boot from embedded SRAM
-
-1. Locate the boot jumpers on the board.
-
-
-
-2. B1_1/B1_0 and B0_1/B0_0 are PTH jumpers which can be moved relatively easy. Note that the markings on the board may not always be accurate. Always refer to the manual for the correct positioning of jumpers in case of doubt. The two jumpers must always be moved together – they are responsible for the boot mode if bootloader is present. The board can search for bootloader on three places – User Flash Memory, System Memory or the Embedded SRAM. We will configure it to boot from SRAM by jumpering B0_1 and B1_1.
-
-3. Connect USB-OTG#2 in the picture above to a USB port on your computer (or a powered USB hub to make sure there is enough power available to the board).
-
-4. The red PWR LED should be lit.
-
-5. Connect the JTAG connector to the SWD/JTAG interface on the board. The other end of the cable should be connected to the USB port or hub of your computer.
-
-
-
-#### Let's Go!
-
-1. Make sure you are in the blinky project directory with the blinky.elf executable. Run the debug command in the newt tool. You should see some status messages are shown below. There is an inbuilt `-c "reset halt"` flag that tells it to halt after opening the session.

-
-2. Voilà! The board's LED should be blinking at 1 Hz.
-
-### Using flash to make LED blink
-
-You are here because you want to build an image to be run from flash memory on the Olimex board.
-
-1. Configure the board to boot from flash by moving the two jumpers together to B0_0 and B1_0. Refer to the pictures of the board under the section titled ["Preparing the hardware to boot from embedded SRAM"](#preparing-the-hardware-to-boot-from-embedded-sram).
-
- You will have to reset the board once the image is uploaded to it.
-
-2. If you skipped the first option for the project [(downloading an image to SRAM)](#using-sram-to-make-led-blink), then skip this step. Otherwise, continue with this step.
-
- By default, the linker script (`olimex_stm32-e407_devboard.ld`) is configured to run from bootloader and flash. However, if you first ran the image from SRAM you had changed `olimex_stm32-e407_devboard.ld` to match `run_from_sram.ld`. You will therefore return to defaults with `olimex_stm32-e407_devboard.ld` linker script matching the contents of 'run_from_loader.ld'. Return to the project directory.
-
- $ cd ~/dev/larva/hw/bsp/olimex_stm32-e407_devboard
- $ diff olimex_stm32-e407_devboard.ld run_from_sram.ld
- $ diff olimex_stm32-e407_devboard.ld run_from_loader.ld
- $ cp run_from_loader.ld olimex_stm32-e407_devboard.ld
- $ cd ~/dev/larva/project/blinky/bin/blinky
-
-3. In order to run the image from flash, you need to build the bootloader as well. The bootloader does the initial bring up of the Olimex board and then transfers control to the image stored at a location in flash known to it. The bootloader in turn requires the bin2image tool to check the image header for version information, CRC checks etc. So, we will need to build these two additional targets (bootloader and bin2img).
-
- Let's first create bin2img:
-
- $ newt target create bin2img
- Creating target bin2img
- Target bin2img successfully created!
- $ newt target set bin2img arch=sim
- Target bin2img successfully set arch to sim
- $ newt target set bin2img compiler=sim
- Target bin2img successfully set compiler to sim
- $ newt target set bin2img project=bin2img
- Target bin2img successfully set project to bin2img
- $ newt target set bin2img compiler_def=debug
- Target bin2img successfully set compiler_def to debug
- $ newt target set bin2img bsp=hw/bsp/native
- Target bin2img successfully set bsp to hw/bsp/native
- $ newt target show bin2img
- bin2img
- arch: sim
- compiler: sim
- project: bin2img
- compiler_def: debug
- bsp: hw/bsp/native
- name: bin2img
-
- And then let's create boot_olimex:
-
- $ newt target create boot_olimex
- Creating target boot_olimex
- Target boot_olimex successfully created!
- $ newt target set boot_olimex arch=cortex_m4
- Target boot_olimex successfully set arch to cortex_m4
- $ newt target set boot_olimex compiler=arm-none-eabi-m4
- Target boot_olimex successfully set compiler to arm-none-eabi-m4
- $ newt target set boot_olimex project=boot
- Target boot_olimex successfully set project to boot
- $ newt target set boot_olimex compiler_def=optimized
- Target boot_olimex successfully set compiler_def to optimized
- $ newt target set boot_olimex bsp=hw/bsp/olimex_stm32-e407_devboard
- Target boot_olimex successfully set bsp to hw/bsp/olimex_stm32-e407_devboard
- $ newt target show boot_olimex
- boot_olimex
- project: boot
- compiler_def: optimized
- bsp: hw/bsp/olimex_stm32-e407_devboard
- name: boot_olimex
- arch: cortex_m4
- compiler: arm-none-eabi-m4
-
-4. Let's build all the three targets now.
-
- $ newt target build bin2img
- Building target bin2img (project = bin2img)
- Building project bin2img
- Successfully run!
- $ newt target build boot_olimex
- Building target boot_olimex (project = boot)
- Building project boot
- Successfully run!
- $ newt target build blinky
- Building target blinky (project = blinky)
- Building project blinky
- Successfully run!
-
-
-5. Go to the project directory and download the bootloader and the image to flash ... in a flash!
-
- $ cd ~/dev/larva/project/blinky/bin/blinky
- $ newt target download boot_olimex
- Downloading with ~/dev/larva/hw/bsp/olimex_stm32-e407_devboard/olimex_stm32-e407_devboard_download.sh
- $ newt target download blinky
- Downloading with ~/dev/larva/hw/bsp/olimex_stm32-e407_devboard/olimex_stm32-e407_devboard_download.sh
-
-6. The LED should be blinking!
-
-7. But wait...let's double check that it is indeed booting from flash and making the LED blink from the image in flash. Pull the USB cable off the Olimex JTAG adaptor. The debug connection to the JTAG port is now severed. Next power off the Olimex board by pulling out the USB cable from the board. Wait for a couple of seconds and plug the USB cable back to the board.
-
- The LED light will start blinking again. Success!
-
- Note #1: If you want to download the image to flash and a gdb session opened up, use `newt target debug blinky` instead of `newt target download blinky`.

The memory location 0x8000000 is the start or origin of the flash memory contents and is specified in the olimex_stm32-e407_devboard.ld linker script. The flash memory locations is specific to the processor.
