Layerscape Linux Distribution POC

LAYERSCAPE-SDK

Layerscape LDP is the industry standard of Linux enablement software for Layerscape family of processors. It provides all the necessary drivers, tools, and libraries required to enable all features of the Arm®-based Layerscape processors.

Layerscape LDP has been tested and qualified, ensuring a fully operational boot loader, kernel, and board-specific modules that are ready to use together within a flexible configuration for specific hardware reference platforms.

There are three ways to use the Linux enablement software from NXP:

  • As a complete reference integration1 with an LDP distro user-space2 which allows users to quickly deploy and test-drive various features on a Layerscape reference design platform.
  • As individual components including kernel drivers, U-Boot and UEFI boot loaders, firmware, and user-space libraries that can be integrated into a Linux distribution. The LDP components are commercial grade and thoroughly tested with years of development expertise going into them. These components form the basis for integration into community, commercial, and customer Linux distributions.
  • As part of open source communities like kernel.org, dpdk.org, denx.de (U-Boot).
Notes:
  1. This is a combination of NXP provided kernel and boot loaders with an LDP distro user-space image.
  2. NXP Layerscape processors are compliant with Arm® standards and are capable of running thousands of Linux applications in binary form.

Comparing Layerscape LDP and the prior Layerscape SDK

  • Layerscape LDP is a fully-featured and mature Yocto-based Linux Distribution POC for Arm-based Layerscape processors. Yocto Software Project is a worldwide industry standard with Community Support. it is easy to build and deploy Linux Distribution. Layerscape SDK is a prior NXP in-house tool, which can provide more flexibility to users. However, it is difficult to continue with this tool as it no longer has Community Support.
  • We recommend customers using Arm-based Layerscape family to migrate to Layerscape LDP for the Linux Distribution build for the most up-to-date enablement software and tools, including support for the latest LTS Linux kernels. We continue to support Yocto as the key Linux Distribution POC going forward.
  • Both Layerscape LDP and prior SDK can be used either as reference Linux integration or as individual NXP components – drivers, tools, libraries, boot loaders etc.
