Use the Yocto Project with NXP LS1046A Freeway Board

Build a custom Yocto image using the powerful NXP LS1046A Freeway Board with Ubuntu Linux

updated: Feb 10, 2024

Overview

This article discusses using an NXP LS1046A Freeway Board with the Yocto Project to build a working system to interoperate with a Private Island^® networking node. We're going to use the Yocto kirkstone release / branch since it has long term support through at least April 2024.

The LS1046A is an amazing networking device, and the Freeway board (shown below) enables many of its features:

Four Gigabit Ethernet ports
WiFi support via M.2 connectors
USB 3.0
Data Path Acceleration Architecture (DPAA) for the high-speed transfer of packet data
Cryptographic acceleration engine
Linux Kernel hardware debug support using NXP Codewarrior.

Setting up the Yocto Project on Ubuntu Linux

This article assumes familiarity with the Yocto Project and that the Ubuntu Linux build machine has already been properly configured. If you are new to Yocto Project, then start with the Quick Build Guide. Also, don't overlook What I Wish I'd Known.

To setup Yocto, we first check out the Git repositories we'll need.

Create our top level build directory.

$ mkdir -p /build/yocto; cd /build/yocto;

Clone and checkout the kirkstone poky branch.

$  git clone https://git.yoctoproject.org/git/poky
Cloning into 'poky'...

$ cd poky/
$ git branch -r 
...
  origin/hardknott
  origin/honister

Build and Boot our First Image

Before we create a custom recipe / image, let's first build and boot core-image-minimal.

$ cd /build/yocto
$ source poky/oe-init-build-env  bld_ls1046afrwy

You had no conf/local.conf file. This configuration file has therefore been
created for you from /build/yocto/poky/meta-poky/conf/local.conf.sample
You may wish to edit it to, for example, select a different MACHINE (target
hardware). See conf/local.conf for more information as common configuration
options are commented.

You had no conf/bblayers.conf file. This configuration file has therefore been
created for you from /build/yocto/poky/meta-poky/conf/bblayers.conf.sample
To add additional metadata layers into your configuration please add entries
to conf/bblayers.conf.

The Yocto Project has extensive documentation about OE including a reference
manual which can be found at:
    https://docs.yoctoproject.org

For more information about OpenEmbedded see the website:
    https://www.openembedded.org/

### Shell environment set up for builds. ###

You can now run 'bitbake <target>'

Common targets are:
    core-image-minimal
...

Modify our "conf/local.conf" file to setMACHINE="ls1046afrwy".

#
# Machine Selection
#
# You need to select a specific machine to target the build with. 
#
MACHINE="ls1046afrwy"

Add "/build/yocto/meta-freescale" to "conf/bblayers.conf".

# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \

Create an Initial Custom Image Recipe

We begin to create our own Yocto custom image recipe below that we'll use to add packages, scripts, and various customizations.

First create a top-level pi-monitor directory:

$ mkdir -p /build/yocto/meta-pi-monitor; cd /build/yocto/meta-pi-monitor

Create conf/layer.conf and add the following to it:

BBPATH .= ":${LAYERDIR}"

BBFILES += "${LAYERDIR}/recipes-*/*/*.bb \
            ${LAYERDIR}/recipes-*/*/*.bbappend"

Create recipes-core/images/pi-monitor.bb and add the following to it:

SUMMARY = "Initial Base Image for PI Monitor"

IMAGE_INSTALL = "packagegroup-core-boot ${CORE_IMAGE_EXTRA_INSTALL}"
IMAGE_INSTALL += "inetutils dhcpcd"
IMAGE_INSTALL += "openssh openssl"
IMAGE_INSTALL += "iputils iptables"
IMAGE_INSTALL += "iproute2 iproute2-tc ethtool"
IMAGE_INSTALL += "util-linux nfs-utils net-tools"
IMAGE_INSTALL += "squid"


IMAGE_LINGUAS = " "

LICENSE = "MIT"

inherit core-image

IMAGE_ROOTFS_SIZE ?= "8192"
IMAGE_ROOTFS_EXTRA_SPACE:append = "${@bb.utils.contains("DISTRO_FEATURES", "systemd", " + 4096", "", d)}"

Our last step before attempting to build our new image recipe is to add our new layer and several meta-openembedded layers to our conf/bblayers.conf file. BBLAYERS is now defined as shown below.

BBLAYERS ?= " \
  /build/yocto/poky/meta \
  /build/yocto/poky/meta-poky \
  /build/yocto/poky/meta-yocto-bsp \
  /build/yocto/meta-freescale \
  /build/yocto/meta-openembedded/meta-oe \ 
  /build/yocto/meta-openembedded/meta-python \ 
  /build/yocto/meta-openembedded/meta-networking \ 
  /build/yocto/meta-pi-monitor \
  "

Try building the new image.
