Wind River LTS releases are supported a minimum
of 10 years under the normal support agreements, with additional support
available through professional services.
The Wind River Linux LTS22 Distro is a binary
distribution based on the Wind River Linux LTS22 distribution builder and is
intended for intelligent edge solution developers who want to leverage the
tremendous investment in embedded device hardware and open-source software made
by Wind River but want to avoid the time and effort of building Linux from
source.
The Distro provides multiple methods for
solution developers to create a purpose-built Linux OS from binary images.
These methods include: micro-start self-deploying images, Linux Assembly Tool
(LAT), dnf package feeds, and a software development kit (SDK).
LTS 22 provides new capabilities for embedded
solution developers to create their own customized embedded Linux OS that are
supported by Wind River. For more information about LTS 22, see the
documentation.
