Virtual Machine[edit | edit source]
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 20.04 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
/tftpboot/desk-mx8m-l/ - NFS: configured through the
/etc/exportsfile
- TFTP: with base directory
- 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[edit | edit source]
 Since your OS, where VirtualBox is running, can be different compared to the version that we using, in case of an error we suggest updating VirtualBox to the latest release patch. For example, if we used |
As stated previously, ORCA SOM host tools are based on a Managed Virtual Machine, we used virtualbox-6.1_6.1.18-142142 to perform virtual machine. As indicated here, microSD card delivered along with ORCA Evaluation Kit includes basic version of MVM that is the default option.
Please follow 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.
Installing the meta-toolchain SDK[edit | edit source]
meta toolchain is preinstalled on DESK-MX8M-L-4.0.0 and it is used for building U-Boot and kernel sources. It can be found in the following path.
dvdk@vagrant:~/desk-mx-l$ ls -la /opt/yocto/sdk/desk-mx8m-l/desk-mx8m-l-4.0.0/ total 40 drwxr-xr-x 3 root root 4096 Jul 24 14:12 . drwxr-xr-x 3 root root 4096 Jul 24 14:11 .. -rw-r--r-- 1 root root 4253 Jul 24 14:11 environment-setup-armv8a-poky-linux -rw-r--r-- 1 root root 14027 Jul 24 14:11 site-config-armv8a-poky-linux drwxr-xr-x 4 root root 4096 Jul 24 14:11 sysroots -rw-r--r-- 1 root root 141 Jul 24 14:11 version-armv8a-poky-linux dvdk@vagrant:~/desk-mx-l$
The installation script can be found in /home/dvdk/desk-mx-l/desk-mx8m-l-4.0.0_meta-toolchain.sh. In case reinstallation would be need, execute following commands.

Installing the application SDK[edit | edit source]
application SDK is preinstalled on DESK-MX8M-L-4.0.0 and it is used for building userspace application. The SDK contains the headers and libraries for building the Qt6 application. It can be found in the following path.
dvdk@vagrant:~$ ls -la ~/desk-mx-l/sdk/desk-mx8m-l-4.0.0/ total 40 drwxr-xr-x 3 dvdk dvdk 4096 Jul 24 14:27 . drwxr-xr-x 3 dvdk dvdk 4096 Jul 24 14:19 .. -rw-r--r-- 1 dvdk dvdk 4231 Jul 24 14:26 environment-setup-armv8a-poky-linux -rw-r--r-- 1 dvdk dvdk 14027 Jul 24 14:26 site-config-armv8a-poky-linux drwxr-xr-x 4 dvdk dvdk 4096 Jul 24 14:19 sysroots -rw-r--r-- 1 dvdk dvdk 141 Jul 24 14:26 version-armv8a-poky-linux dvdk@vagrant:~$

Using the SDK[edit | edit source]
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-4.0.0_env.sh
MITO 8M Mini SDK[edit | edit source]
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.
