Known issues

Reference Issue Workaround
2959498 CPSW driver requires elevated io-privity. TI firmware restricts access to an address space needed by the tiudma-mgr driver by requiring Arm EL1 privilege. The CPSW io-sock driver must be run with EL1 IO privity and the parameter, qnx.iolevel="2", was placed in the configuration file /etc/iosock.cfg that is named on the driver’s command line.
2978244 TI SBL has been tested with an older build of the BSP and due to the mismatch in SDP build, networking hasnt been fully tested on SBL. Requires an updated SBL Build from TI.
2970414 DHCP doesnt work with the following CPSW package com.qnx.qnx800.target.net.devs.cpsw/0.0.2.00435T202407181105L. Install the following CPSW package, com.qnx.qnx800.target.net.devs.cpsw/0.0.3.02005T202411230033L, in the SDP installation. To re-build the BSP to support the latest CPSW Package, we recommend that you search and remove the following binaries:

$BSP_ROOT/install/aarch64le/lib/dll/devs-cpsw-j742s2.so

$BSP_ROOT/prebuilt/aarch64le/lib/dll/devs-cpsw-j742s2.so

$BSP_ROOT/binary_files_with_symbols/aarch64le/lib/dll/devs-cpsw-j742s2.so.sym

and then run the following: 
cp $Path_to_SDP_installation/target/qnx/aarch64le/lib/dll/devs-cpsw-j784s4.so $BSP_ROOT/prebuilt/aarch64le/lib/dll/devs-cpsw-j742s2.so
cd $BSP_ROOT
make clean
make

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.
