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 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/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.

Installing the meta-toolchain SDK

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/

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.

dvdk@vagrant:~$ cd desk-mx-l/
dvdk@vagrant:~/desk-mx-l$ ./desk-mx8m-l-4.0.0_meta-toolchain.sh -d /opt/yocto/sdk/desk-mx8m-l/desk-mx8m-l-4.0.0 -y

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

Installing the application SDK

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/

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-4.0.0_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.
