==Introduction==

* build the bootloader (U-Boot)

* build and debug applications that will be executed on top of Yocto-based Linux distribution running on the target.

The main kit components are:

* development host released in the form of [[Managed_Virtual_Machine_(MVM)|Managed Virtual Machine]], tailored for [[Managed_Virtual_Machine_(MVM)#Yocto-based_Linux_distribution|Yocto-based distribution]]

* technical documentation (hardware manuals, mechanical drawings, reference schematics, application notes etc.)

The documents related to the software issues help the user to quickly start configuring the bootloader and the operating system, by hiding most of the complexity of the underlying hardware. '''Reading of the [[Managed_Virtual_Machine_(MVM)|Managed Virtual Machine documentation]] is strongly recommended''', as it plays a '''major role''' in the SDVX organization.

=== SDVX microSD Layout ===

The microSD card provided with SDVX is partitioned as shown in the following image:

<code>bootscript</code> and root file system are used to boot the target as described in [[#Target_setup_and_first_boot|this section]].

====How to create a bootable microSD card====

Please note that this process '''implicitly updates git source code repositories of U-Boot and/or Linux kernel'''. Thus '''it is strongly recommended to create new local branches if you need to modify source code'''.

=== Release notes ===

==== SDVX 1.0.0 ====

===== Known issues and limitations =====

**2: VIN

*insert microSD card in the slot J13.

By default, U-Boot is configured to retrieve Linux kernel image stored in the microSD card. In turn, Linux kernel shall mount the correct root file system from the microSD card depending on the version of the board one is using. For the '''lite''' version, the root file system is stored in the <code>mmcblk0p2</code> partition, while the '''ul''' uses the <code>mmcblk0p3</code> partition. At the end of the boot process, Linux shell shall be available on the serial console.

===Developing the software for the target===

Please refer to[[Developing the software for the target (SDVX)| this page]].

===Debugging with Eclipse===

To build your first application, start the QtCreator from the command line with the following command:

<pre>

sdvx-qtcreator [target]

</pre>

where the target is '''ul''' for ''sdvx-ul'' or '''lite''' for ''sdvx-lite''

<pre class="workstation-terminal">

dvdk@ubuntu-xenial:~$ sdvx-qtcreator ul

Starting QtCreator for sdvx-ul

</pre>

{{ImportantMessage|text=It is important to start QtCreator with the above script each time you close it}}

This command will take care of sourcing the correct environment for the target device. After that, one can follow this guide to compile and debug the[[XELK-AN-004: Getting Started With QT Creator#Qt application example| Qt application example]]. You should probably want to change the '''ip-address''' of your kit as explained [[XELK-AN-004: Getting Started With QT Creator#Devices | here]]

</pre>

Moreover, if one intends to build '''Qml''' application for the '''sdvx-ul''' board, it is necessary to start the Qml application with

<pre>

export QMLSCENE_DEVICE=softwarecontext

</pre>

For example, to start the '''Qt5 Cinematic Experience''' application that is installed inside the

devel RFS it is necessary to run:

<pre class="workstation-terminal">

root@sdvx-ul:~# export QMLSCENE_DEVICE=softwarecontext

libpng warning: iCCP: known incorrect sRGB profile
