== 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.
[[File:AxelUltra-AxelEVB.jpg|thumb|center|600px|Axel Ultra/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 a null-modem (https://en.wikipedia.org/wiki/Null_modem) cable (not provided)
#*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===
XELK SD card contains all binary images required for booting the system completely from kernel/dtb (stored on first SD <code>fat</code> card partition) to <code>ext3</code> root file system (stored on second SD card partition).
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]].
