    We do not have a Keith&Koep specific Zeus Yocto recipe.
    In short, we describe how to build the generic NXP Yocto recipe and patch this with Seco U-Boot and Linux 5.4, Trizeps VIII (-/Mini/Nano)-Kernel.

    Yocto Project Setup

    This is only a quick-reference on how to setup and build a Yocto image.
    For details please view the Linux and NXP i.MX8M documentation. Especially the „i.MX_Yocto_Project_User's_Guide“.

    $ mkdir <project-dir> $ cd <project-dir> $ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b <Branch> -m <Manifest-File> $ repo sync

    Example

    $ mkdir imx-yocto-bsp $ cd imx-yocto-bsp $ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-zeus -m imx-5.4.24-2.1.0.xml $ repo sync

    When this process is completed, the source code is checked out into the directory imx-yocto-bsp/sources.
    You can perform repo synchronization, with the command repo sync, periodically to update to the latest code.

    Example

    Image Build

    After the setup of the build-environment, you can start to run bitbake to build the image.

    Project-Image

    Target

    Provided by layer

    Project-Image

    Target

    Provided by layer

    core-image-minimal

    A small image that only allows a device to boot.

    Poky

    core-image-base

    A console-only image that fully supports the target device hardware.

    Poky

    core-image-sato

    An image with Sato, a mobile environment and visual style for mobile devices. The image supports a Sato theme and uses Pimlico applications. It contains a terminal, an editor and a file manager.

    Poky

    imx-image-core

    An i.MX image with i.MX test applications to be used for Wayland backends. This image is used by our daily core testing.

    meta-imx/meta-sdk

    fsl-image-machine-test

    An FSL Community i.MX core image with console environment - no GUI interface.

    meta-freescale-distro

    imx-image-multimedia

    Builds an i.MX image with a GUI without any Qt content.

    meta-imx/meta-sdk

    imx-image-full

    Builds an opensource Qt 5 image with Machine Learning features. These images are only supported for i.MX SoCwith hardware graphics. They are not supported on the i.MX 6UltraLite, i.MX 6UltraLiteLite, i.MX 6SLL, and i.MX 7Dual.

    meta-imx/meta-sdk

    After reboot or opening a new terminal window, you can restart the build environment with:

    Example

    After a build is complete, the image can be found at <build-dir>/tmp/deploy/images.
    The image_name will be <Project-Image>-<Machine>.sdcard.bz2; i.e. imx-image-multimedia-imx8mmevk.sdcard.bz2.

    Deploy Image

    How to deploy the image depends on wether you have a module with eMMC oder uSD-card-slot.
    For a module with eMMC you will use the NXP Universal Update Utility (UUU) to update the files while the module is in USB Serial Download Mode.
    For a module with uSD-Slot you can either use NXP Universal Update Utility (UUU) or deploy the image directly to the uSD-card using an uSD-card-reader with your PC.

    Flash Image to SD card

    Identify the uSD-card plugged to your PC; i.e. by using „lsblk | grep disk“

    Flash Image to eMMC

    Put the module into USB Serial Download Mode and run:

    Patch Image with Seco Linux Bootloader and Kernel

    Bootloader

    U-Boot

    Select Device-Tree

    After flashing the image you will need to select the correct device-tree for your device.

    This can be done in two ways:

    1. Through the bootloader-console (115k2, 8N1):

    You can get a list of installed *.dtb files by calling „fatls mmc 0“.

    1. Rename the wished device-tree file (.dtb) to the default fdt_file setting:

    Module

    Default fdt_file setting

    Module

    Default fdt_file setting

    Trizeps VIII

    kuk-trizeps8.dtb

    Trizeps VIII Mini

    kuk-trizeps8mini.dtb

    Myon II

    kuk-trizeps8mini.dtb

    (Myon II and Trizeps VIII Mini use the same bootloader )
