Virtual Machine

DAVE' standard DVDK Virtual Machine contains all the required software and documentation to start developing Linux applications on the ORCA and MITO 8M Mini platforms. In particular, DESK-MX8M-L provides a virtual machine, called DVDK, with the following features:

• VirtualBox virtual machine (.OVA archive)
• based on Lubuntu 16.04 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 /srv/tftp/
  • NFS: configured through the /etc/exports file
• secondary disk containing source code and tools:
  • bootloader (u-boot) 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
  • Yocto BSP for ORCA SOM and MITO 8M Mini SOM
• pre-installed Yocto-based root file systems with setup scripts, makefiles, example applications, ...
• administrator account (dvdk) with autologin. Please note that the user account credentials are provided with the development kit (you can find them in the README file contained in the sw/dvdk folder of the kit distribution)
  • user: dvdk
  • password: dvdk

Please note that u-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 and MITO 8M Mini SOMs.

Host setup

As stated previously, ORCA SOM host tools are based on a Managed Virtual Machine. As indicated here, microSD card delivered along with 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 this page.

MVM can be downloaded here. For accessing DESK Reserved area please contact our helpdesk support channel

To install it, please refer to this page.

DVDK for release 2.0.0-rc2

The Virtual Machine used for the ORCA and MITO 8M Mini SOMs is the same used for the DESK-MX6-L development environment. Here below you can find the simple instructions for installing the rc2 release for DESK-MX8M-L BSP using DESK-MX6-L Virtual Machine.

Additional library

• libssl-devel is required for building the linux kernel: it is enough to install the library in the VM

dvdk@vagrant:~/desk-mx-l$ sudo apt-get install libssl-dev

Installing the meta-toolchain SDK

• open a Desktop Linux Terminal
• download the proper SDK from the mirror server fsl-imx-wayland-glibc-x86_64-meta-toolchain-aarch64-desk-mx8mp-toolchain-5.4-zeus.sh

dvdk@vagrant:~/desk-mx-l/sdk$ wget http://mirror.dave.eu/desk-mx-l/desk-mx8m-l-2.0.0/fsl-imx-wayland-glibc-x86_64-meta-toolchain-aarch64-desk-mx8mp-toolchain-5.4-zeus.sh

• SDK installation

dvdk@vagrant:~/desk-mx-l/sdk$ chmod 755 fsl-imx-wayland-glibc-x86_64-meta-toolchain-aarch64-desk-mx8mp-toolchain-5.4-zeus.sh

======================================================
Enter target directory for SDK (default: /opt/fsl-imx-wayland/5.4-zeus): /home/dvdk/desk-mx-l/sdk/desk-mx8m-l-2.0.0-toolchain
You are about to install the SDK to "/home/dvdk/desk-mx-l/sdk/desk-mx8m-l-2.0.0-toolchain". Proceed [Y/n]? Y
Extracting SDK.................................................................................................................done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
 $ . /home/dvdk/desk-mx-l/sdk/desk-mx8m-l-2.0.0-toolchain/environment-setup-aarch64-poky-linux
dvdk@vagrant:~/desk-mx-l/sdk$ 

• create a symbolic link to the SDK directory latest version

ln -s /home/dvdk/desk-mx-l/sdk/desk-mx8m-l-2.0.0-toolchain latest_desk-mx8-l-toolchain

• create the environment script for enabling the toolchain (during the development phase) and make it executable

dvdk@vagrant:~/desk-mx-l$ {
>   echo \# DESK-MX8M-L development environment for u-boot/kernel development
>   echo 
>   echo source /home/dvdk/desk-mx-l/sdk/latest_desk-mx8-l-toolchain/environment-setup-aarch64-poky-linux
> } | tee > /home/dvdk/desk-mx-l/desk-mx8m-l-2.0.0_env.sh
dvdk@vagrant:~/desk-mx-l$ chmod 755 desk-mx8m-l-2.0.0_env.sh
dvdk@vagrant:~/desk-mx-l$ 

• once installed, if required for freeing some space, the SDK file can be removed:

rm fsl-imx-wayland-glibc-x86_64-meta-toolchain-aarch64-desk-mx8mp-toolchain-5.4-zeus.sh

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 fsl-imx-wayland-glibc-x86_64-desk-image-qt5-aarch64-desk-mx8mp-toolchain-5.4-zeus.sh script has been created by DAVE's Yocto building when the desk-image-qt5-desk-mx8mp.tar.bz2 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:

dvdk@vagrant:~/desk-mx-l/sdk$ ls -la
total 435052
drwxr-xr-x 5 dvdk dvdk      4096 Feb 14 16:38 ./

lrwxrwxrwx 1 root root        51 Apr  9  2021 latest_desk-mx6-l-toolchain -> /home/dvdk/desk-mx-l/sdk/desk-mx6-l-1.0.0-toolchain
lrwxrwxrwx 1 dvdk dvdk        57 Feb 14 16:38 latest_desk-mx8-l -> /home/dvdk/desk-mx-l/sdk/desk-mx8m-l-2.0.0-rc2

dvdk@vagrant:~/desk-mx-l/sdk$ 

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-2.0.0-rc2_env.sh

MITO 8M Mini SDK

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.
