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. |
| 2966149 | SDR104 SD Cards may not be detected after being ejected and reinserted. This issue is also present on previous releases of this BSP. | Reboot device. |
| 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. |
| 2959591 | The NOR flash on a given board may have been left in Hybrid mode after hardware manufacturing. Attempting to erase, partition, or mount filesystems may generate errors. Please refer back to future versions of these release notes or contact QNX for updated information. | None available |
| 2959498 | The 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. |
| 2948425 | PCI device isn't recognized. | The PCI topology needs to be specified in the PCI HW configuration file using the DEV_LIST option. |
| 2925797 | Device does not restart after the watchdog timer expires. | The boot files provided do not trigger an SOC reset when the watchdog expires. Please contact Texas Instruments for more information. |
Licensing information
The QNX SDP licensing, packaging, and fulfillment model from the previous release has been carried forward to this release.

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.
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.
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.
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-j721e.so
prebuilt/aarch64le/lib/dll/devs-cpsw-j721e-diag.so
binary_files_with_symbols/aarch64le/lib/dll/devs-cpsw-j721e-diag.so.sym
binary_files_with_symbols/aarch64le/lib/dll/devs-cpsw-j721e.so.sym
