Licensing information

The QNX SDP licensing, packaging, and fulfillment model from the previous release has been carried forward to this release. That is, QNX SDP will be available in the QNX Download Center and QNX Software Center as a new product baseline. Additionally, the license agreements will include a few enhancements for clarifications but otherwise will remain unchanged.

Getting started with this BSP

We recommend that you read the Building Embedded Systems guide, which contains common information about working with all BSPs. This guide is available on the QNX Software Development Platform 8.0 documentation website.

Note:

To ensure that you pick up the same components from your development environment, we recommend that you rebuild the IFS image on your host system.

This BSP includes prebuilt IFS images to quickly get you up-and-running; however, these images might not have the same components as your development environment.
