Virtual Machine

DAVE' standard DVDK Virtual Machine provides a virtual machine, called DVDK, with the following features:

• VirtualBox virtual machine (.OVA archive)

• pre-installed VirtualBox Guest Additions
• LXDE desktop environment
• VSCode with dev-container plugin
• boot disk with the distro and pre-configured basic Linux services:
  • TFTP: with base directory /tftpboot/
  • NFS: configured through the /etc/exports file
• 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

Host setup

Host tools are based on a Managed Virtual Machine tested on virtualbox-7.2_7.2.12-174389 version.

MVM can be downloaded here. For accessing DESK Reserved area please contact our helpdesk support channel. To install it, please refer to this page.

DESK-MX-L and DESK-XZ-L source codes are publicly available and can be downloaded via HTTPS without authentication. Source code for customer-specific products, on the other hand, is hosted in restricted git repositories that require SSH key access. To enable it, please refer to this page

Installing the meta-toolchain SDK

meta toolchain SDK can be installed to build U-Boot and kernel sources:

• download from the mirror server and launch the installation file (an example is below):

dvdk@vagrant:~$ mkdir desk-mx-l && cd desk-mx-l
dvdk@vagrant:~/desk-mx-l$ wget https://yocto.dave.eu/desk-mx8m-l-7.0.0-rc0/sdk/fsl-imx-wayland-glibc-x86_64-meta-toolchain-armv8a-imx8mm-lpddr4-evk-toolchain-6.18-wrynose.sh
dvdk@vagrant:~/desk-mx-l$ ./fsl-imx-wayland-glibc-x86_64-meta-toolchain-armv8a-imx8mm-lpddr4-evk-toolchain-6.18-wrynose.sh -d /opt/yocto/desk-mx8mm-l/desk-mx8mm-l-7.0.0 -y

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.
 $ . /opt/yocto/desk-mx8mm-l/desk-mx8mm-l-7.0.0/environment-setup-armv8a-poky-linux

Using the SDK

Anytime it is required to compile u-boot or kernel sources, it is enough to enable it using the script:

dvdk@vagrant:~/desk-mx-l$ source /opt/yocto/desk-mx8mm-l/desk-mx8mm-l-7.0.0/environment-setup-armv8a-poky-linux 
dvdk@vagrant:~/desk-mx-l$ echo $CC
