Release Notes[edit | edit source]

DAVE Embedded Systems adds to the latest Linux BSP from NXP the customization required to support the SOC platform. For this reason most of the documentation provided by NXP remains valid for the DESK development kit.

However, some customization is required, in particular at bootloader and linux kernel levels.

The following table reports the DESK releases information.

  • show U-Boot splashscreen earlier

Known Limitations[edit | edit source]

The limitations are the same of DESK-MX6-L-4.0.0

Downloadable binary images[edit | edit source]

All binary images for DESK-MX6-L are hosted on DAVE Embedded System mirror server. There you can find a sub directory for each version of this development kit.

U-Boot performs 2-stage bootloader providing two files: SPL and u-boot.img. Both two files must be stored into SD card using dd command.

A summary of images with a brief description can be found into the table below:

Image DESK-MX6-L version 4.0.1
Platform SBCX - SBCX560012C2R
Carrier Board ConfigID 0012
LCD panel Ampire 800 x 480 7" LVDS 262K colors (RGB666)
Touchscreen resistive
SPL SPL (Quad / NOR) SPL (DualLite / NAND)
u-boot.img (Quad / NOR) (DualLite / NAND)
Linux kernel uImage
Device tree (QUAD) imx6q-sbcx-cb0012.dtb
Device tree (DualLite) imx6dl-sbcx-cb0012.dtb

Yocto images and built-in packages[edit | edit source]

Yocto target images for DESK-MX6-L are hosted on DAVE Embedded System mirror server. There are more build targets which include a list of built and installed packages in the root file system image.

A summary of built images and their included packages can be found in the table below:

Image DESK-MX6-L version 4.0.1
root file system packages list
devel desk-image-devel.bz2 image-devel_installed-packages.txt
qt6 fb desk-image-qt6-fb.bz2 image-qt6-fb_installed-packages.txt

Release notes:

  • Major change to NXP BSP 5.15.71
  • Updated U-Boot and kernel versions
  • Updated Yocto version
  • Updated Qt version

Known Limitations[edit | edit source]

The following table reports the known limitations of this DESK release:

New MVM must be installed for using DESK-MX6-L-1.0.0. The VM is available for download on DAVE's XELK Reserved Area for registered users.

Release notes:

  • Major change to NXP BSP 4.14.98

Issue Description
NAND Samsung NAND Model K9F4G08U0D not detected in u-boot
Linux kernel xconfig make xconfig does not work

Release types[edit | edit source]

DESK release type can be:

  • Major, when substantial changes are applied to the BSP (eg: major kernel version upgrades) or to the development kit (eg: new features, build system updates, ..). This usually means that a new DVDK is created for the DESK release
  • Maintenance, when minor updates and bug fixes are introduced. This usually means that the DVDK remains the same provided with the previous major version, and only an update of the source tree repositories (and the tftp binaries) is required

As an example, DESK 1.1.0 is a maintenance release, so it provides the DVDK released with the 1.0.0 major release; customers can easily upgrade to the 1.1.0 release by updating the software components as described in Synchronizing git repositories.

Supported platforms[edit | edit source]
