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:<pre class="workstation-terminal">dvdk@dvdk-vm:~$ cd /home/dvdk/axel/linux/dvdk@dvdk-vm:/home/dvdk/axel/linux$ git fetch origin</pre>up to date with DAVE Embedded Systems' repositories.
Please note that Once the git account has been enabled, the developer can:*clone the repository with the <code>git fetchclone <git_remote_repository></code> doesn't merge command *synchronize a source tree entering the commits on repository directory and launching the current branch<code>git fetch origin</code> command. To do that, you should run
Please note that git fetch doesn't merge the commits on the current branch. To do that, 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].

===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 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 null-modem cable (https://en.wikipedia.org/wiki/Null_modem) cable (''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)
