Known issues

Reference Issue Workaround
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 and rebuild the IFS by running make clean and make from $BSP_ROOT.
Not available TI SBL does not load .dtb files. TI’s SBL needs to be updated to load a .dtb file prior to booting QNX SDP 8.0. Until then, the missing .dtb will prevent the use of io-sock drivers on the CPSW controller(s). To use a CPSW controller, refer to the user's guide for this BSP for instructions on how to load the .dtb and boot from U-Boot.
2962099 OSPI Tuning/Calibration. The OSPI PHY calibration methodology is still under development. Calibrations errors may be reported but will not impact functionality given nominal operating conditions. Please refer back to these Release Notes or contact QNX for updated information.
2959591 NOR flash in hybrid mode. The NOR flash on a given board may have been left in Hybrid mode after hardware manufacturing. The ability to erase/partition and mount filesystems may report errors. Please refer back to these Release Notes or contact QNX for updated information.
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.
2961508 OSPI driver with PSDK doesn't compile on windows. The following changes needs to be made in the $BSP_ROOT_DIR/src/hardware/flash/boards/j7-ospi/extra.mk:

  1. Remove these 4 lines:

    LIBS += $(PSDK_QNX_PATH)/qnx/pdk_libs/pdk/aarch64/so.le/libti-pdk.so
LIBS += $(PSDK_QNX_PATH)/qnx/pdk_libs/sciclient/aarch64/so.le/libti-sciclient.so
LIBS += $(PSDK_QNX_PATH)/qnx/pdk_libs/udmalld/aarch64/so.le/libti-udmalld.so
LIBS += $(PSDK_QNX_PATH)/qnx/resmgr/udma_qnx_rsmgr/usr/aarch64/so.le/libtiudma-usr.so

  2. Replace them with:

    EXTRA_INCVPATH += $(PSDK_QNX_PATH)/pdk/packages
EXTRA_INCVPATH += $(PSDK_QNX_PATH)

EXTRA_LIBVPATH+=$(PSDK_QNX_PATH)/qnx/pdk_libs/pdk/aarch64/so.le
EXTRA_LIBVPATH+=$(PSDK_QNX_PATH)/qnx/pdk_libs/sciclient/aarch64/so.le
EXTRA_LIBVPATH+=$(PSDK_QNX_PATH)/qnx/pdk_libs/udmalld/aarch64/so.le
EXTRA_LIBVPATH+=$(PSDK_QNX_PATH)/qnx/resmgr/udma_qnx_rsmgr/usr/aarch64/so.le
LIBS+=ti-pdk
LIBS+=ti-sciclient
LIBS+=ti-udmalld
LIBS+=tiudma-usr

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.

Note:

Using latest networking package com.qnx.qnx800.target.net.iosock >= 0.0.2.00417T202407041502L: To re-build this BSP to support latest networking packages, we recommend that you search and remove the following binaries and run make clean and make from $BSP_ROOT and rebuild the IFS:

prebuilt/aarch64le/lib/dll/devs-cpsw-j784s4.so

prebuilt/aarch64le/lib/dll/devs-cpsw-j784s4-diag.so

binary_files_with_symbols/aarch64le/lib/dll/devs-cpsw-j784s4-diag.so.sym

binary_files_with_symbols/aarch64le/lib/dll/devs-cpsw-j784s4.so.sym
