DESK-MX6UL-L contains all the required software and documentation to start developing Linux application on the AXEL ULite platform. In particular, DESK-MX6UL-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 /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 AXEL ULite 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

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 AXEL ULite SOM.

Guest Addictions[edit | edit source]

Guest Addictions installation may fail if the VirtualBox version is different from the VM linux kernel version.

In case of VBox error message:

Error: kernel headers not found

as suggested here, install the correct kernel header using the following command:

sudo apt-get install linux-headers-`uname -r`

and the run the Guest Addictions install

dvdk@vagrant:/media/dvdk/VBox_GAs_6.1.18$ sudo ./
