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 Images

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“.
...
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.
Distribution | Remarks |
|---|---|
fsl-imx-wayland | Wayland weston graphics. |
fsl-imx-xwayland | Wayland graphics and X11. X11 applications using EGL are not supported. |
fsl-imx-fb | Frame Buffer graphics - no X11 or Wayland. Frame Buffer is not supported on i.MX 8. |
Machine | Remarks |
|---|---|
imx8mmevk | NXP i.MX 8M Mini Eval-Kit. Use for Trizeps VIII Mini, Myon II, SBCSOM |

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:
...
Patch Image with Seco Linux Bootloader and Kernel
Bootloader
Linux-Kernel
Linux 5.4, Trizeps VIII (-/Mini/Nano)
Select Device-Tree
After flashing the image you will need to select the correct device-tree for your device.
...
Rename the wished device-tree file (.dtb) to the 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 )
