===== Preface =====


The //meta-tq// layer extends the //Yocto Project's// reference system //Poky// to provide support for a selection of TQ Embedded CPU Modules, including the @mod_name@.
<WRAP hide>
It uses the same codebase as the [[..:arm:@mod_name@:linux:ptxdist:overview|PTXdist based TQ Linux BSPs]] and therefore provides the same versions of U-Boot and Linux kernel, but doesn't define a specific root filesystem configuration.
</WRAP>
<callout type="primary" icon="true">
Because of the dependencies to the other yocto layers we recommend to use [[https://github.com/tq-systems/ci-meta-tq|ci-meta-tq]] which already provides all required yocto layers as git submodules instead of [[https://github.com/tq-systems/meta-tq|meta-tq]] to  build this BSP release. 
</callout>
The instructions on this page refer to the BSP and ancillary tools listed in the following table:

<alert type="warning">It's strongly recommended to use **git** for downloading both the //Yocto Project / Poky// Release as well as //ci-meta-tq// (instead of downloading archives and extracting them)</alert>

<callout type="primary" icon="true">
The goal of these wiki pages is to get you started using //ci-meta-tq// with the @stk_name@, so instead of reinventing the wheel we will adhere to the very compact [[https://@yocto_doc_base_url@/@yocto_rel_ver_major@.@yocto_rel_ver_minor@/brief-yoctoprojectqs/brief-yoctoprojectqs.html|Yocto Project Quick Start]] and supply details specific to the @stk_name@ where necessary.\\
\\
For further details regarding //Yocto Project// @yocto_rel_ver_major@.@yocto_rel_ver_minor@ - @yocto_rel_name@ please refer to its [[https://www.yoctoproject.org/docs/archived-documents/|official documentation]].
</callout>

<panel type="default" title="Prerequisites">

//Yocto Project / Poky// requires a Linux build host, so first of all you need a development workstation (or a virtual machine((for testing purposes //Yocto Project// provides a ready to use virtual machine called [[https://www.yoctoproject.org/tools-resources/projects/build-appliance|Build Appliance]]))) 
with a Linux distribution installed.

Please refer to section [[https://@yocto_doc_base_url@/@yocto_rel_ver_major@.@yocto_rel_ver_minor@/brief-yoctoprojectqs/brief-yoctoprojectqs.html#brief-compatible-distro|Compatible Linux Distribution]] of the //Yocto Project Quick Start// for supported linux distributions and section [[https://@yocto_doc_base_url@/@yocto_rel_ver_major@.@yocto_rel_ver_minor@/brief-yoctoprojectqs/brief-yoctoprojectqs.html#brief-build-system-packages|Build Host Packages]] for required build host packages for those distributions.

<callout type="primary" icon="true">
The instructions on this page have been tested on @host_os_name@ @host_os_version@ (@host_os_bits@) in a VMWare virtual machine.
</callout>
Although not required by //Yocto Project / Poky//, we also recommend to configure and run a [[en:tftp|tftp server]] (for image download / update) and an [[en:nfs|nfs server]] (for network mounted root filesystem) on your development host.

<panel type="default" title="Yocto Build instructions">

<alert type="warning">Please setup the build host as described in the [[..:arm:@mod_name@:linux:yocto:quickstart_yocto#Prerequisites]] section above .</alert>

1. Create a local copy of @mtq_repos@
<code>
$ git clone --recurse-submodules https://github.com/tq-systems/ci-meta-tq.git
</code>
2. Checkout BSP release on new local branch.
<code>
$ cd ci-meta-tq
$ git checkout @yocto_rel_branch@.@yocto_rel_branch_module@.BSP.SW.@yocto_rel_branch_rev@ -b @yocto_local_branch_name@
</code>
3. Update git submodules:
<code>
$ git submodule update --init
$ git submodule sync
</code>
4. Setup local branch to track the remote branch.
<code>
git branch -u origin/@yocto_local_branch_name@
</code>
5. Configure the Build((valid machines are\\ @mtq_machines@)):
<code>
$ source fsl-setup-release.sh -b @mod_name_code@_build -e wayland
$ echo 'MACHINE = "@mtq_machine_default@"' >> conf/local.conf
</code>
6. Build an Image for @stk_name@:
<code>
$ bitbake @mtq_image@
</code>
<wrap help round center 80%>The resulting image is ''tmp/deploy/images/@mtq_machine_default@((valid machines are\\ @mtq_machines@))/@mtq_image@-@mtq_machine_default@((valid machines are\\ @mtq_machines@)).wic''</wrap>\\ 
7. Write the Image((valid machines are\\ @mtq_machines@))((''TARGET_DEVICE'' has to be an SD card))
<code>
$ sudo dd if=tmp/deploy/images/@mtq_machine_default@/@mtq_image@-@mtq_machine_default@.wic of=TARGET_DEVICE
</code>
8. Boot the @stk_name@ from SD card (cf. [[..:arm:@mod_name@:@mb_name_code@:dip_switches|@mb_name@ DIP switch settings]])  |
