Changes

==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.)

==Additional documentation==

== SDVX software components ==

'''DAVE Embedded Systems''' adds to the latest Linux BSP from NXP/Freescale the customization required to support the Axel platform. For this reason most of the documentation provided by NXP/Freescale remains valid for the SDVX development kit. However, some customization is required, in particular at bootloader and linux kernel levels.

=== SDVX microSD Layout ===

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 ====

* First official release

Once power is applied to the target, the U-Boot bootloader will be fetched from the flash internal storage (NOR/NAND/eMMC depending on order code) and executed. Boot messages will be printed out to the serial console. Redundant U-Boot environment is stored in the flash as well, as depicted in the following image.

===Host setup===

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

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

==Advanced topics==

===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]]

If the target device is '''sdvx-lite''', the command line arguments are

</pre>

If the target device is '''sdvx-ul''', the command line arguments are

<pre>

</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

</pre>
