Ezurio WB source HowTo

Ezurio no longer makes public software releases for WB products, for the customer specific private release, please contact you Sales or Support Representative

Preparation

To use to pull and build a specific project or version, you first need the program Repo from the Android project. You can get it by following the instructions here:

https://source.android.com/source/downloading.html#installing-repo

Getting the WB project

First step, pick which release you want. Odds are you want the most recent of your release. Below shows how to "map" a release number to a GA release:

• GA2 : 3.4.x.x
• GA3 : 3.5.0.x
• GA4 : 3.5.1.x
• GA5 : 3.5.2.x
• GA6 : 3.5.3.x
• GA7 : 3.5.4.x

Next, use Repo to initalize and fetch your release. This is a two-step process: first you tell Repo which manifest to use and then you tell it to fetch everything.

mkdir wb_3.5.4.46_source
cd wb_3.5.4.46_source
repo init -u https://github.com/LairdCP/wb-manifests.git -m wbXXn_3.5.4.46.xml
repo sync

For GA releases up to (including) GA4, the manifest is called wb45n_version.xml.

For GA releases from GA5 and up, the manifest is called wbXXn_version.xml.

Note: Repo will initialize a .repo directory and then place all files directly in the directory that you are in when you run the repo command. So we recommend making a subdirectory and working in there.

Building the WB project

There's more to go into about this, but for the sake of quick-start:

cd wb
make wb45n

To make the wb50n:

make wb50n

To make a wb50n_rdvk:

make wb50n_rdvk

Build sources archive

We maintain a buildroot source binary archive on GitHub. Sometimes the source of the packages goes missing temporarily, or have been moved since last we updated the package in buildroot. Additionally, the Laird MSD packages our builds depend on are also in the repository.

If cloned, and your BR2_DL_DIR is set to this directory, then a build won't have to go and download the source. Alternately, any missing packages you can't find can be directly downloaded from GitHub and added to your BR2_DL_DIR.

GitHub:

https://github.com/LairdCP/wb-package-archive

Clone:

git clone git@github.com:LairdCP/wb-package-archive.git

Add to environment:

export BR2_DL_DIR=/home/derosier/projects/wb-package-archive

For GA4 and earlier versions, BUILDROOT_DL_DIR is the equivalent variable name. Please use this instead.

Setting the version number

By default the version number in /etc/summit-release will read similar to:

Laird Linux development build 20161220

Our production builds set /etc/summit-release during the build process; a missing release file triggers the build-system to place the development version number in it. You can set the release version number by doing the following for your build before you run make:

VERSION=3.5.3.11
export LAIRD_RELEASE_STRING="Laird Linux wb45n-laird-${VERSION}"

The above is what our Jenkins build system does for each release build.

Known source issues

Can't find the MSD package

Applies to: All versions

The MSD package needs to be downloaded from the Laird website or our wb-package-archive.git and placed where Buildroot can find it. If you use a BUILDROOT_DL_DIR or BR2_DL_DIR, place the file there.

Can't find crda source package

Applies to: GA2, GA3

The crda source package was moved since our last Buildroot update. We've since adjusted our code for future releases, but old releases will be unable to find the package. You can either copy the package from our package archive or apply the patch.

A. Copy:

 cd $BUILDROOT_DL_DIR
 wget https://github.com/LairdCP/wb-package-archive/blob/master/crda-1.1.3.tar.bz2?raw=true

B. Patch:

diff --git a/package/crda/crda.mk b/package/crda/crda.mk

Build error on wget

Applies to: GA2, GA3, GA4 on newer build hosts

wget has a bug where it won't build on platforms with newer perl pod2man. More details can be found here: http://lists.gnu.org/archive/html/bug-wget/2013-06/msg00008.html

It was found that it's possible to pass through the error by simply reissuing the build command. Alternately, upgrading the wget package to a newer version can fix the problem. Change the WGET_VERSION = 1.14 in wb/buildroot/package/wget/wget.mk file to version 1.15 to fix.

Known affected build hosts:

• Ubuntu 14.04

Known good build hosts:

• Ubuntu 12.04 LTS
• Ubunut 13.10
