Getting Started with NXP-based Wireless Modules on i.MX 8M Quad EVK Running Linux OS
4 i.MX 8M EVK Linux image setup
The i.MX 8M Quad Linux BSP is a collection of binary files, source code, and support
files used to create a U-Boot bootloader, a Linux kernel image, and a root file system for
i.MX 8M Quad development platforms.
All the information on how to set up the Linux OS host, how to run and configure a Yocto
Project, generate an image, and generate a rootfs, are covered in the i.MX Yocto Project
User's Guide. On i.MX 8M Quad, four elements are needed:
• imx-boot (built by imx-mkimage), which includes SPL, U-Boot, Arm Trusted Firmware,
DDR firmware, and HDMI firmware
• Linux kernel image
• A device tree file (.dtb) for the board being used
• A root file system (rootfs) for the specific Linux image

4.1 Using the pre-built image
This section describes the steps to prepare eMMC to boot up an i.MX 8M Quad EVK
using a Linux host machine. The pre-built image can be downloaded from the page
Embedded Linux for I.MX Application Processors on NXP website. Accept NXP software
license agreement when prompted.
The release contains a pre-built image that is built specifically for the board configuration.
It does not run on other boards unless U-Boot, the device tree, and rootfs are changed.
Note: A pre-built image contains all the image elements and does not require to build
the image using the Yocto setup. So the user can skip Section 4.2 "Setting up the host",
Section 4.3 "Building the image", and Section 4.3.3 "Image deployment".
