Release Notes

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.

Release types

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 2.1.0 is a maintenance release, so it provides the DVDK released with the 2.0.0 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

The following table reports the supported platforms in this DESK release:

Platform	Description
SBC ORCA	Single Board Computer using ORCA SOM as Evaluation Kit
SBC AXEL	Single Board Computer using MITO 8M Mini SOM as Evaluation Kit
