* VirtualBox virtual machine (.OVA archive)
* based on Lubuntu 1620.04 LTS (64-bit version)
* pre-installed VirtualBox Guest Additions
* LXDE desktop environment
* boot disk with the distro and pre-configured basic Linux services:
** TFTP: with base directory <code>/srvtftpboot/tftpdesk-mx8m-l/</code>
** NFS: configured through the <code>/etc/exports</code> file
* secondary disk containing source code and tools:
** bootloader (uU-bootBoot) source tree cloned from DAVE Embedded Systems public git repository
** Linux kernel source tree cloned from DAVE Embedded Systems public git repository
** external pre-built toolchain
** password: '''dvdk'''
Please note that uU-boot Boot and kernel source trees are derived from the official trees released by NXP/Freescale; these trees have been customized to add support for the [[ORCA SOM| ORCA]] and [[MITO 8M Mini SOM | MITO 8M Mini]]SOMs.
===Host setup===
As stated previously, [[ORCA SOM]] host tools are based on a [[Managed_Virtual_Machine_(MVM)|Managed Virtual Machine]]. As indicated [[ORCASOM/ORCA Evaluation Kit/Getting started/Unboxing#microSD_Layout|here]], microSD card delivered along with [[ORCA SOM/ORCA Evaluation Kit | ORCA Evaluation Kit]] 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]].
MVM can be downloaded [https://cloud.dave.eu/ws-reservedRA-areaDESK-xelkMX/ here]. For accessing <b><i>DESK Reserved area</i></b> please contact our [mailto:helpdesk@dave.eu helpdesk support channel]
To install it, please refer to [[VirtualBox_Starting_DVDK_Virtual_Machine#Using_a_.ova_file|this page]].
=== DVDK for release 2.0.0Installing the ''meta-rc2 toolchain'' SDK ===The Virtual Machine used for the [[ORCA SOM | ORCA]] and [[MITO 8M Mini SOM | MITO 8M Mini]] SOMs is the same used for the [[DESK-MX6-L | DESK-MX6-L]] development environment. Here below you can find the simple instructions for installing the ''rc2meta toolchain'' release for is preinstalled on [[DESK-MX8M-L | /General/Release_Notes#DESK-MX8M-L]] BSP using [[L_4.0.0 | DESK-MX6MX8M-L | DESK-MX6-L4.0.0]] Virtual Machineand it is used for building U-Boot and kernel sources. It can be found in the following path.
==== Additional library ====
* <code>libssl-devel</code> is required for building the linux kernel: it is enough ot install the library in the VM
dvdk@vagrant:~/desk-mx-l/linux$ sudo apt-get install libssl-dev
==== Installing the ''meta-toolchain'' SDK ====
* open a Desktop Linux Terminal
* download the proper SDK from the mirror server <code>fsl-imx-wayland-glibc-x86_64-meta-toolchain-aarch64-desk-mx8mp-toolchain-5.4-zeus.sh</code>

* once installed, if required for freeing some space, the SDK file can be removed:
rm fsl-imx-waylandThe installation script can be found in <code>/home/dvdk/desk-glibc-x86_64-meta-toolchain-aarch64mx-l/desk-mx8mpmx8m-toolchainl-54.4-zeus0.0_sdk.sh</code>. In case reinstallation would be need, execute following commands.
==== Installing the ''application'' SDK ====
The previously installed SDK is used for building u-boot and kernel sources. For building userspace application another SDK has to be used: the <code>fsl-imx-wayland-glibc-x86_64-desk-image-qt5-aarch64-desk-mx8mp-toolchain-5.4-zeus.sh</code> script has been created by DAVE's Yocto building when the <code>desk-image-qt5-desk-mx8mp.tar.bz2</code> root file system has been created: it contains the SDK headers and libraries for building the Qt5 application too.
 
The same previously described operations can be followed for installing this SDK in the same directory. At the end, both SDK are installed and present into the rfs:

</pre>
==== Using the SDK ====
Anytime it is required to compile u-boot or kernel sources, it is enough to enabling it using the script:
source /home/dvdk/desk-mx-l/desk-mx8m-l-24.0.0-rc2_env0_env.sh
==== MITO 8M Mini SDK ====
[[MITO 8M Mini SOM| MITO 8M Mini]] has the same 4-cores Cortex-A53 architecture: even if Yocto builds two SDK, it is possible to install and use the previously described/used SDK file for both SOM modules/architectures.
