For more information about the access to these repositories, please refer to [[Building_the_Yocto_BSP_(XELK)|this link]].
This means that these components can be kept in sync and up Access to date with '''DAVE Embedded Systems''' git repositories. ==== RSA key generation ==== Please follow the procedure reported below is granted to generate the RSA ssh key: * select your username (ad es. username@myhost.com)* start the DVDK and login into the virtual machine* start a shell session* enter the .ssh subdirectory into your home directory: <code>cd ~/.ssh/</code>* launch the following command: <br><pre>ssh-keygen -t rsa -C "username@myhost.com" -f username@myhost.com</pre>* this command creates the files <code>~/.ssh/username@myhost.com</code> (development kit'''private key''') and <code>~/.ssh/username@myhosts owners only.com.pub</code> ('''public key''')* edit your <code>~/.ssh/config</code> adding the following lines: <pre>Host git.dave.eu User git Hostname git.dave.eu PreferredAuthentications publickey IdentityFile ~/.ssh/username@myhost.com</pre> Please send the public key file refer to one of the following email support addresses (depending on which SOM is included in your kit version) * [mailto:support-axel@dave.eu support-axel@dave.eu[Accessing_DAVE_Embedded_Systems_restricted_git_repositories|this page]] with the request for the creation of a new public git account associated detailed instructions on how to your username. The support team will enable the account and send you a confirmation as soon as possibleget access.
==== Synchronizing the repository ====
When The components listed in the account is enabled, you table above can synchronize a source tree entering the repository directory be kept in sync and launching the <code>git fetch</code> command, like in the following example:up to date with DAVE Embedded Systems' repositories.
Once the git account has been enabled, the developer can:*clone the repository with the <pre class="workstation-terminal"code>dvdk@dvdk-vm:~$ cd /home/dvdk/xelk/linux-2.6-imxgit clone <git_remote_repository></code> command dvdk@dvdk-vm:/home/dvdk/xelk/linux-2.6-imx$ *synchronize a source tree entering the repository directory and launching the <code>git fetch origin</precode>command.
Please note that <code>git fetch</code> doesn't merge the commits on the current branch. To do that, you the developer should run  the <pre class="workstation-terminal"code>git merge origin/axel</precode> 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/documentation Git Documentation].

===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]].
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 UltraSOM /(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 12Vcc 12V power supply to the JP2 socket on the DACU board#(optional) To access the serial console:#*Connect a serial cable between the J251 connector on the DACU board and PC COM port through , using a NULLnull-modem cable (https://en.wikipedia.org/wiki/Null_modem) cable (''not provided'', between provided#** 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 (optionalsee picture above) start #*Start your favorite terminal software on PChist side; communication parameters are:#**Baud rate: 115200 Bps#**Data bits: 8#**Stop bits: 1#**Parity: none#(optional) to To connect the system to Ethernet LAN, please plug cable on connector J6 connector of the AXELEVB-LiteThe system is configured to boot automatically from the SD card when powered up.
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 class=>echo 'bootscript generated with command "mwmkimage -collapsible mwA ARM -collapsedT script -C none -n XELK -d bootscript.txt boot.scr">' setenv fdtfile imx6q-xelk-l.dtbsetenv 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]].
