NI Linux Embedded (NILE)

This repository provides the necessary configuration and git submodules required to build the NI Linux Embedded distribution.

The initial implementation sets up the OpenEmbedded build system with meta-xilinx and other layers required to build images for Xilinx development boards and some vendor boards.

OpenEmbedded allows the creation of custom Linux distributions for embedded systems. It is a collection of git repositories known as layers each of which provides recipes to build software packages as well as configuration information.

Information about the branch names is available at https://wiki.yoctoproject.org/wiki/Releases.

Authentication to internal repos

This layer contains recipes that depend on NI-internal repositories. These require git to be aware of authentication credentials.

• Create an AzDO Personal Access Token
• Create the following file at $HOME/.netrc with the generated token:

  machine dev.azure.com login api password <azdo access token>
  

Getting Started

NILE is built using kas. The pyrex/submodule-based workflow is still present but is deprecated.

1. Clone the git repository:

   $ git clone https://github.com/ni/nile.git
   

2. Check out the appropriate branch (default scarthgap based branch is OK for now):

   $ cd nile
   

3. Build docker image for kas

   $ bash ./docker/create-build-nile.sh --base kas
   

   Verify the image was created:

   $ docker images build-nile
   

4. Build an image:

   $ ./kas-container build kas/targets/nile-image-dev_kula.yml
   

5. Test it in qemu with:

   $ ./kas-runqemu kas/targets/nile-image-dev_kula.yml
   

6. Build an sdk:

   $ ./kas-container build kas/targets/meta-toolchain_genericarm64.yml
