QNX SDP is a cross-compiling and debugging environment, including an IDE and command-line tools, for building binary images and programs for ARM v7, ARM v8, and x86_64 targets running the QNX Neutrino RTOS 7.1.

Board Support Packages (BSP) are available for various hardware platforms on QNX SDP 7.1. This is a release note for the Texas Instruments Sitara AM572x EVM (AM572x EVM) BSP. This BSP also supports the Beaglebone-X15 board.

Throughout this document, you may see reference numbers associated with particular issues, changes, etc. When corresponding with our Technical Support staff about a given issue, please quote the relevant reference number. You might also find the reference numbers useful for tracking issues as they become fixed.

Known issues

For common QNX Software Development Platform issues that may impact this BSP, see the QNX Software Development Platform 7.1: Release Notes.

This BSP has the following known issues:

• The SATA driver (devb-ahci-omap5) fails to start. (Ref# J2872916)

  Workaround: None.

• The ping command on the target fails when the Ethernet driver command specifies the dm814x-j6 driver with the option p0speed or p1speed set to 10. For example, if the following command is run, the ping command no longer works:

  io-pkt-v4 -ddm814x-j6 deviceindex=0,p0speed=10,p0duplex=1 -ptcpip

  (Ref# J788389)

  Workaround: If you start the Ethernet driver using the dm814x-j6 driver, specify a value other than 10 for the p0speed or p1speed option.

Getting started with this BSP

Each BSP has a user's guide that describes what's in the BSP and how to install and work with it. In a browser, after you log in with your myQNX account, you can download the latest revision of the user's guide from the QNX SDP 7.1 Board Support Documentation page.

We recommend that you read the Building Embedded Systems guide, which contains common information about working with all BSPs from QNX Software Systems. This guide is available on the QNX Software Development Platform 7.1 documentation website.

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. Included in this BSP are prebuilt IFS images that are provided as convenience for you to quickly get QNX Neutrino running on your board, however these prebuilt images might not have the same components from your development environment.
