Build the BSP (commandline)

You can use the commandline on Linux or Windows to work with this BSP.

Makefile targets in the BSP

The Makefile is located under the $BSP_ROOT_DIR/images directory. It defines more than one target:

all
Builds the QNX IFS (with and without graphics) and QNX IPL files for the target.
qnx-ifs
Builds the IFS file.
qnx-ifs-graphics
Builds the IFS file with graphics.
ifs-imx8mp-evk
Builds the IFS file for U-Boot.
ipl
Builds QNX IPL (.imx) file for the i.MX 8MP EVK board for SD or eMMC boot and for xSPI NOR flash memory boot.

If you don't specify a target, make invokes the all target.

Note:
  • The mkimage_imx8.exe utility uses multiple Linux utilities (e.g., dd.exe, sha256sum.exe, etc.) to create the *.imx bootable images in the $BSP_ROOT_DIR/images directory. To build the *.imx bootable images using Windows, some utilities are needed from a GNU tool installation such as CygWin or MinGW GNU tools. We recommend that after you install either MinGW GNU tool or CygwWin to your host system and that you check that the PATH environment variable contains a path to the dd.exe, sha256sum.exe, etc. utilities on your host system.
  • In case the mkimage_imx8.exe utility does not work in your development environment, you can download the latest source from https://github.com/nxp-imx/imx-mkimage.git and rebuild it.

Build from the commandline

To build the BSP on your host system, in a Command Prompt window (Windows) or a terminal (Linux), you must first build at the root directory of the BSP (BSP_ROOT_DIR), then you can build using the Makefile targets described previously in the $BSP_ROOT_DIR/images directory. To build your BSP, perform the following steps:

  1. Download the BSP archive, unzip it, and set up your environment to build. For more information, see Download and set up the BSP.
  2. In the BSP's images directory ($BSP_ROOT_DIR/images), type make clean to remove the default image files from the $BSP_ROOT_DIR/images directory. 
    $ cd $BSP_ROOT_DIR
$ cd images
$ make clean

    This action removes all existing image files.

  3. Navigate back to the BSP_ROOT_DIR and type make. Running make does the following:
    • builds the BSP and creates its directories
    • places any images required for the board into the $BSP_ROOT_DIR/images directory
$ cd $BSP_ROOT_DIR
$ make

You should now have an IFS file called qnx-ifs.

Note:
After you build, there might be multiple IFS files in the $BSP_ROOT_DIR/images directory if your Makefile builds multiple IFS files.
Note:
We recommend that you use the make command to build your QNX IFS image. If you use the mkifs utility directly, ensure that you use the -r option to specify the location of the binaries.
