The i.MX 8M Plus EVK comes with a pre-built NXP Linux binary demo image flashed on the eMMC. Without modifying the binary inside, booting from the eMMC provides a default system with certain features for building other applications on top of Linux.
To understand more about NXP’s Embedded Linux®, Embedded Android™ or MCUXpresso SDK, continue reading the next sections.

Connect the supplied micro-B USB cable to the debug UART port
J23
, then connect the other end of the cable to a host computer.
Four UART connections will appear on the host computer. The third port is for
A53
core and the fourth port is for
M7
core system debugging.

The boot sequence is detailed in the i.MX 8M Plus Reference Manual . In short, the boot modes of the i.MX boards are controlled by the boot configuration switches.
The switches set the boot media (depending on board, i.e. SD card, eMMC, NAND), the serial download protocol mode (SDP) or the value set on eFuses.
The SDP is also the fallback for the boot media, in other words, when the switches are configured to boot from SD card but the SD card slot is empty, or the SD card binary content is not bootable, the boot sequence continues to the SDP boot.

Connect the power supply cable to the power connector (PORT0
).
Power the board by flipping the switch (SW3
).
The processor starts executing from the on-chip ROM code. With the default boot switch setup, the code reads the fuses to define the media where it is expected to have a bootable image. After it finds a bootable image, the U-Boot execution should begin automatically.
Information is printed in the serial console for the Cortex® A53. If you do not stop the U-Boot process, it continues to boot the kernel.
Congratulations, Linux Boots
As the board boots up, you will see 4 penguins appear in the upper left-hand corner of the monitor, and then you will see the Linux terminal icon on the top left and timer on right top corner. Congratulations, you are up and running.

This section is applicable ONLY if attempting to load a Linux operating system on the board.
The i.MX Linux Board Support Package (BSP) is a collection of binary files, source code and support files that are used to boot an Embedded Linux image on a specific i.MX development platform.
Current releases of Linux binary demo files can be found on the i.MX Linux download page. Additional documentation is available in the i.MX Linux documentation bundle under the Linux sections of the i.MX Software and Development Tools.
Before the Linux OS kernel can boot on an i.MX board, the Linux kernel is loaded to a boot device (SD card, eMMC and so on) and the boot switches are set to boot that device.
There are various ways to download the Linux BSP image for different boards and boot devices.
This Getting Started guide only outlines a few methods of transferring the Linux BSP to an SD card. Experienced Linux developers can explore other options if desired.

The latest pre-built images for the i.MX 8M Plus EVK are available on the Linux download page under the most current version on Linux.
The pre-built NXP Linux binary demo image provides a typical system and basic set of features for using and evaluating the processor. Without modifying the system, the users can evaluate hardware interfaces, test SoC features and run user space applications.
When more flexibility is desired, an SD card can be loaded with individual components (boot loader, kernel, dtb file and rootfs file) one-by-one or the *wic
image is loaded and the individual parts are overwritten with the specific components.

In addition to the connections from "Out of the Box" section, connect the PORT1
to the host machine using the proper USB cable.
Turn off the board. Consult the "1.5 Boot Switch Setup" section and configure the board to boot on serial download protocol (SDP) mode.
Depending on the OS used in the host machine, the way to transfer the Linux BSP image onto an SD card can vary. Choose an option below for detailed instructions:

This section describes the boot process of loading the i.MX 8M Plus EVK board with an Embedded Android system image and introduces how to build the software components that create your own system image. For details on building the Android platform, see this Android building guide .
The current release includes demo images, source code and documentation. These can also be found in Android OS for i.MX Applications Processor.
The storage devices on the development system (MMC/SD or NAND) must be programmed with the i.MX bootloader. The boot process determines which storage device to access based on the switch settings. When the boot loader is loaded and begins execution, the U-Boot environment space is then read to determine how to proceed with the boot process.
The images can come from pre-built release packages or be created from source code. Regardless of how you obtain them, all Android images contain the following components:
u-boot.imx
boot.img
system.img
recovery.img
For more information about the Android BSP, refer to the Android user guide.

Machine learning (ML) typically encompasses applications where classification, recognition and prediction of man-made abstractions are desired. Examples include image recognition, gesture recognition, anomaly detection, speech-to-text, text-to-speech, ASR, scene recognition and many more. This section will focus specifically on the NXP ML tools applied to image or video streams. The audio section may reference the included examples.

Docker On i.MX8MM with Ubuntu | This document describes a way to create ubuntu rootfson host pc and install docker for any ARM 64 platform. |
On the command prompt of the Linux host machine, run the following command to determine the port number:
$ ls /dev/ttyUSB*
The smaller number is for Arm® Cortex®-A53 core and the bigger number is for Arm® Cortex®-M4 core.
Use the following commands to install and run the serial communication program (minicom
as an example):
$ sudo apt-get install minicom
$ sudo minicom /dev/ttyUSB* -s
Figure 3. Minicom Configuration.
The FTDI USB-serial chip on i.MX8MQuad enumerates two serial ports. Assume that the ports are COM9
and COM10
. The smaller numbered port ( COM9
) is for the serial console communication from Arm® Cortex®-A53 and the larger numbered port (COM10
) is for Arm® Cortex®-M4 core. The serial-to-USB drivers are available at VCP Drivers
Note: To determine the port number of the i.MX board virtual COM port, open the Windows device manager and find USB serial Port in Ports (COM and LPT).
