Reference Issue Workaround
Not available This BSP enables watchdog with timeout value of 2500ms which may need to be adjusted. Please refer to the User's Guide for specific instructions on how to adjust the timeout value of watchdog timer. None available
2972632 Startup includes physical addresses 0x0 to 0x1000 to the memory available to the operating system. However, these addresses are reserved by the firmware, and their use by the operating system can lead to instability. Add -r 0,4096,1 argument to startup in the BSP buildfile.

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.
