en:templates:yocto_x86:yocto_meta-tqmx86_qs

The meta-tqmx86 layer extends the Yocto Project's reference system Poky to provide support for all TQ x86-Modules including the MOD_NAME.

The goal of these wiki pages is to get you started using meta-tqmx86 with the STK_NAME, so instead of reinventing the wheel we will adhere to the very compact Yocto Project Quick Start and supply details specific to the STK_NAME where necessary.

This layer depends on a number of base layers, which are listed in the following. The Yocto versions “gatesgarth” and “hardknott” are supported at this time. The correct branch matching the Yocto version must be checked out for each layer.

It's strongly recommended to use git for downloading both the Yocto Project / Poky sources (instead of downloading archives and extracting them)

Build Host

Yocto Project / Poky requires a Linux build host, so first of all you need a development workstation (or a virtual machine¹⁾) with a Linux distribution installed.

Please refer to section Compatible Linux Distribution of the Yocto Project Quick Start for supported linux distributions and section Build Host Packages for required build host packages for those distributions.

The instructions on this page have been tested on HOST_OS_NAME HOST_OS_VERSION (HOST_OS_BITS) in a VMWare virtual machine.

Although not required by Yocto Project / Poky, we also recommend to configure and run a tftp server (for image download / update) and an nfs server (for network mounted root filesystem) on your development host.

1. Create Workspace Folder

$ mkdir workspace
$ cd workspace

2. clone both the meta-intel and our meta-tqmx86 repository and checkout the branch you want to use. In this example we use POKY_BRANCH:

$ git clone https://github.com/tq-systems/meta-tqmx86.git
$ cd meta-tqmx86
$ git checkout <label poky_branch>POKY_BRANCH</label>
$ cd ..
$ git clone https://git.yoctoproject.org/git/meta-intel
$ cd meta-intel
$ git checkout <label poky_branch>POKY_BRANCH</label>

3. clone the official poky repository and checkout the branch you want to use:

$ cd ..
$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ git checkout <label poky_branch>POKY_BRANCH</label>

4. initialize the buildspace using the oe-init-build-env script. This script creates a build folder and enters it directly:

$ . oe-init-build-env

5. In order to use the meta-tqmx86 and meta-intel layer you need to make the build system aware of it. open the file bblayers.conf with your favorite editor to add the layers:

nano conf/bblayers.conf

The file should look similar to the following after the adjustment:

for testing purposes Yocto Project provides a ready to use virtual machine called Build Appliance
