Support Policy
SDKs and BSPs are offered free of charge, "AS IS." Please review the Linux Technology Support Policies for more information.
Supported Linux Distros
In addition to the Layerscape components and hybrid Ubuntu support, we also provide support for a variety of popular embedded and server Linux distros. We work together with various open-source communities like Yocto project, OpenWRT, ONIE/ONL and OpenIL to ensure that support for our platforms is available as part of the regular releases from these distro communities. Our Layerscape components form a common base that is re-used across these various distros and maintains consistency across PowerPC based QorIQ P and T-series family and Arm®v8 based Layerscape family.
- Yocto (QorIQ P/T-series and LS-series)
- Yocto layer which manages the recipes of BSP level packages, e.g. fm-ucode, u-boot, kernel.
- Yocto layer which manages the recipes of SDK distro related packages, e.g. EdgeScale package, demo images.
- Repo manifest project which facilitates the download of all required layers of Yocto SDK.
- OpenWRT / LEDE (LS-series)
- ONIE / ONL (QorIQ P/T-series and LS-series)
QorIQ SDK or Layerscape SDK – which to choose?
- QorIQ SDK is a fully featured and mature Yocto-based software kit for both Arm-based Layerscape QorIQ Power Architecture-based P-series and T-series families of processors.
However, Layerscape SDK provides much more flexibility to users in terms of choice of distro, community code-base, ease-of-use. - We recommend customers using both Arm-based Layerscape and Power-based QorIQ P-series and T-series family to migrate to Layerscape SDK or the Linux distros for the most up to date enablement software and tools, including support for the latest LTS Linux kernels. For legacy compatibility with QorIQ SDK, we continue to support Yocto as one of the key Linux distro options going forward.
- Both QorIQ and Layerscape SDK can be used either as reference Linux integration or as individual NXP components–drivers, tools, libraries, boot-loaders etc.
