== XELK 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 XELK development kit. However, some customization is required, in particular at bootloader and linux kernel levels.
The following table reports the XELK releases information.

====Downloadable binary images====
All binary images for XELK are hosted on [[TBDmirror:axel|DAVE Embedded System mirror server]]. There you can find a sub directory for each version of this development kit.
A summary of images with a brief description can be found into the table below:
{{ImportantMessage|text=In order to boot Linux from SD card files, '''the binary files must be renamed''' as follows:
*bootscript: <code>boot.scr</code>
*Linux kernel: <code>uImage</code>
*Device tree: <code>imx6ul-lynx-som000c.dtb</code>
U-boot file <code>u-boot.imx</code> must be stored into first raw sector of the SD card using <code>dd</code> command}}  {{ImportantMessage|text=Since '''XELK-3.5.0''' U-boot performs 2-stage bootloader providing two files: SPL and u-boot.img.
Both two files must be stored into SD card using <code>dd</code> command}}

For more information about the access to these repositories, please refer to [[Building_the_Yocto_BSP_(XELK)|this link]].
 
Access to DAVE Embedded Systems' git repositories is granted to development kit's owners only. Please refer to [[Accessing_DAVE_Embedded_Systems_restricted_git_repositories|this page]] for detailed instructions on how to get access.
 
==== Synchronizing the repository ====
 
The components listed in the table above can be kept in sync and up to date with DAVE Embedded Systems' repositories.
 
Once the git account has been enabled, the developer can:
*clone the repository with the <code>git clone <git_remote_repository></code> command
*synchronize a source tree entering the repository directory and launching the <code>git fetch origin</code> command.
 
Please note that git fetch doesn't merge the commits on the current branch. To do that, the developer should run the <code>git merge</code> command or replace the ''fetch-merge'' process with a single <code>git pull</code> command. Please note that the recommended method is the ''fetch-merge'' process. For further information on Git, please refer to the official Git Documentation (http://git-scm.com
 
== Release types ==
 
XELK release type can be:
* '''Major''', when substantial changes are applied to the BSP (eg: major kernel version upgrades) or to the development kit (eg: new features, build system updates, ..). This usually means that a new DVDK is created for the XELK release
* '''Maintenance''', when minor updates and bug fixes are introduced. This usually means that the DVDK remains the same provided with the previous major version, and only an update of the source tree repositories (and the tftp binaries) is required
 
As an example, XELK 2.2.0 is a maintenance release, so it provides the DVDK released with the 2.0.0 major release; customers can easily upgrade to the 2.2.0 release by updating the software components as described in [[Axel_Embedded_Linux_Kit_(XELK)#XELK_Updates|XELK Updates]].

== Quick start guide ==
This chapter describes how to quickly start working with the XELK kit. The following paragraphs will guide you through the setup and installation procedures.
 
===Kit registration===
{{ImportantMessage|text='''Customers are strongly recommended to register their kits'''. Registration grants access to reserved material such as source code and additional documentation.}}
 
To register the kit, please send an email to [mailto:support-axel@dave.eu support-axel@dave.eu], [[Development_Kits_Identification_Codes|providing the kit P/N and S/N]].
 
If you also wish to access git repositories containing source code, please follow the procedure described [[Accessing_DAVE_Embedded_Systems_restricted_git_repositories|here]].
 
===Target setup and first boot===
This section describes how to quick start the AxelEVB board delivered along with XELK kit (see also the following image). The hardware setup is the same for AxelUltra and AxelLite SOMs.
 
The picture below shows the AxelLite SOM inserted into the AxelEVB: please note the first HW release of {{oldid|3287|AxelEVB-Lite}}
[[File:AxelLite-AxelEVB.jpg|thumb|center|600px|Axel Lite SOM / (first) AxelEVB setup]]
 
The picture below shows the AxelUltra SOM inserted into the AxelEVB: please note the new HW release of [[AxelEVB-Lite]]
[[File:AxelUltra-AxelEVB.jpg|thumb|center|600px|Axel Ultra SOM / (latest) AxelEVB setup]]
 
The microSD provided with the XELK can be used to boot the system, since it contains a bootable partition (<code>mmcblk0p1</code>) and a root file system partition (<code>mmcblk0p2</code>).
#Insert the MicroSD card provided with the development kit into the microSD slot
#Connect the 12V power supply to the JP2 socket on the DACU board
#(optional) To access the serial console:
#*Connect a serial cable, using a null-modem cable (https://en.wikipedia.org/wiki/Null_modem) ''not provided'', between
#** the J251 connector on the DACU board and PC COM port - for the latest AxelEVB-Lite HW version (see picture above)
#** the J28 connector on the AxelEVB-Lite and PC COM port - for the first AxelEVB-Lite HW version (see picture above)
#*Start your favorite terminal software on hist side; communication parameters are:
#**Baud rate: 115200 Bps
#**Data bits: 8
#**Stop bits: 1
#**Parity: none
#(optional) To connect the system to Ethernet LAN, please plug cable on connector J6 connector of the AXELEVB-Lite
 
By default, the system is configured to boot automatically from the microSD card when powered up.
 
===Binary images on SD card===
 
{{ImportantMessage|text=The XELK bootable microSD card delivered along with the kit is set up to do a full bootstrap sequence. For more details, please refer to [[Working_with_the_Yocto_build_system#bootscript|this section]].}}
 
Once you got the new binaries compiled from your modified sources, they have to be installed on first SD partition preserving the original file names used into <i>boot.scr</i> u-boot bootscript.
 
Otherwise, you may create a new '''boot.scr''' file using different file names. Here below there is an example on how to create a boot.scr file for booting from SD card:
 
The '''bootscript.txt''' is the text version of the <i>boot.scr</i> file:
 
<pre>
echo 'bootscript generated with command "mkimage -A ARM -T script -C none -n XELK -d bootscript.txt boot.scr"'
 
setenv fdtfile imx6q-xelk-l.dtb
setenv bootfile uImage
 
setenv mmc_loadk 'fatload mmc ${mmcdev}:1 ${loadaddr} ${bootfile}'
setenv mmc_loadfdt 'fatload mmc ${mmcdev}:1 ${fdtaddr} ${fdtfile}'
setenv mmcboot 'run mmc_loadk mmc_loadfdt mmcargs addip addcons addmisc adddisp0; bootm ${loadaddr} - ${fdtaddr}'
 
echo Booting AxelLite-XELK via mmcboot
 
run mmcboot
 
echo mmcboot FAILURE
</pre>
 
and compile it using:
 
<pre>
mkimage -A ARM -T script -C none -n XELK -d bootscript.txt boot.scr
</pre>
 
Then copy the kernel, dtb and boot.scr into the SD card first partion (the FAT one) and boot XELK with the new images.
 
===Host setup===
As stated previously, XELK host tools are based on a [[Managed_Virtual_Machine_(MVM)|Managed Virtual Machine]]. As indicated [[Axel_Embedded_Linux_Kit_(XELK)#XELK_microSD_Layout|here]], microSD card delivered along with XELK includes basic version of MVM that is the default option.
 
Please follows the README file on the SD card to extract the ''*.ova'' archive and to install the MVM.
 
It is also worth remembering that access to git repositories is required to download target source code. To enable it, please refer to [[Accessing_DAVE_Embedded_Systems_restricted_git_repositories|this page]].
 
{{ImportantMessage|text=The MVM provides the tools required to build [[Building_U-Boot_(XELK)|U-boot]] and [[Building_Linux_kernel_(XELK)|Linux kernel]]. It does not include the tools required to run Yocto build system instead.}}
 
XELK MVM can be downloaded [https://cloud.dave.eu/ws-reserved-area-xelk/XELK-3.0.1 here]. For accessing <b><i>XELK Reserved area</i></b> please contact our [mailto:sales@dave.eu sales department]
 
===Target configuration for the development stage (<code>net_nfs</code>)===
 
{{ImportantMessage|text=The default XELK Virtual Machine network configuration is using NAT: this allows to accessing external network (i.e. Internet) using the host computer's networking connection.
For software development using <code>net_nfs</code> with tftp/nfs protocols, please configure your VM network interface in ''Bridge mode'' (see below)}}
 
During the development stage, the target is usually connected via Ethernet LAN to the host machine and is configured to:
*retrieve binary images (i.e. Linux kernel) via TFTP protocol
*mount the development root file system via NFS protocol. This root file system is physically in the file system of the host machine as depicted [[Deploying_Embedded_Linux_Systems#The_development_environment|here]]. An example of ''Bridge mode'' configuration for DIVELK can be found [[Booting_from_NFS_(XELK) | here]]
In DAVE Embedded Systems development kits, this configuration is generally denoted as <code>net_nfs</code>. U-Boot bootloader supports this configuration. Some U-Boot environment variables are needed to set it up. They are detailed [[Booting_Linux_Kernel#Configuration_net_nfs|here]].
 
For more details about TFTP and NFS servers on host side, please refer to this [[Setting_up_tftp_and_nfs|page]].
 
===Target configuration for standalone boot===
Please refer to [[Standalone_boot_(XELK)|this page]].
