QNX® Software Development Platform 7.1 Board Support Package for the NXP i.MX 8QuadXPlus: Release Notes

Date of this edition: June 26, 2020

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 NXP i.MX 8QuadXPlus (i.MX 8QXP) BSP.

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.

Note:

A QNX BSP may be made available as an Experimental, Validated, or General Availability (GA) release, depending on factors such as software maturity and terms of commercial availability.

You should check the location where you downloaded your BSP for information about the current type of release offered for your BSP.

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:

  • Transmit errors may occur when you use the serial driver (devc-sermx8 or devc-sermx8-dma) when you enable software flow control (i.e., use the -s option). (Ref# J2872747)

    Workaround: Don't enable software flow control (i.e., don't specify the -s option) when you start the serial driver.

  • On Windows, you can't build the bootable images for NOR Flash (ipl-imx8qxp-cpu_flash_b0.imx and ipl-imx8qxp-cpu_flash_c0.imx). The other bootable images (SD card and eMMC) for this BSP build without issue on Windows. (Ref# J2728656)

    Workaround: If you need to rebuild the NOR Flash bootable image, use a Linux host to build it; otherwise use the prebuilt NOR flash file provided with this BSP.

  • On macOS, the QNX IPL image fails to build when you try to build this BSP. (Ref# J2645720)

    Workaround: None. If you need to rebuild the QNX IPL, you must build it on a Windows or Linux host.

  • The PCI Server works only under the 4 GB memory range.

    Workaround:

    For the PCI server to support the 4G memory limit, comment out the following line in the startup header file, $BSP_ROOT_DIR/src/hardware/startup/boards/imx8x/qm-cpu-card/board.h: 
    #define IMX_SDRAM1_SIZE 4096
    After you save the changes, rebuild the image, and reboot your board with it. When you start the PCI server, the PCI server should now start.
  • If you connect a USB hub to the board, disk-on-key USB devices connected to the hub aren't recognized. For example, if you type the usb command in your terminal or console, you won't see the USB devices that are connected to the USB hub. (Ref# J2788348)

    Workaround: Connect your disk-on-key USB devices directly to the USB port on the board.

  • The headset jack's MIC and ground wires are backwards.

    Workaround: Use an OMTP to CTIA adapter so that you can then plug a standard headset into the board.

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.

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.

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.
