* VirtualBox virtual machine (.OVA archive)

* Based on Lubuntu 1214.04 LTS (64-bit version)

* Pre-installed VirtualBox Guest Additions

* LXDE desktop environment

* Updated Yocto version

* Updated Qt version

=== XELK 3.5.0 ===

* Release date: 04/2019

* Status: Released

* NXP Linux BSP: L4.1.15-2.0.0

* Supported carrier boards: AxelEVB-Lite on Dacu, SBCX

==== Notes ====

{{ImportantMessage|text=NXP iMX6 silicon revision 1.4 limited the u-boot binary size (due to bug fix in bootrom code). This required the switch to u-boot SPL version (first and second stage).}}

* Major change to u-boot SPL version

* Updated u-boot version

=== XELK 3.0.1 ===

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 boot.scr 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 boot.scr 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 XELK Reserved area 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]].
