Chapter 1 Introduction
1.1 Target Board: MaaXBoard 8ULP
MaaXBoard 8ULP is a development board developed by Avnet, Which featuresthe NXP i.MX 8ULP
processor to achieve ultra-low power, EdgeLock® secured intelligent edge applications.
MaaXBoard 8ULP is engineered as two PCBs, a small SOM (43mm x 36mm) connected via 2x100-pin
connectors to a baseboard (BB) in compact Raspberry Pi form-factor, which supports a versatile set of I/O
interfaces. These include 100M Ethernet, two USB 2.0 host interfaces, plus separate USB 2.0 device
interface, MIPI DSI display and MIPI CSI camera interfaces, a Pi-HAT compatible 40-pin header, MikroE
Click 16-pin header plus ADC/DAC 6-pin header.
1.2 Introduction
This document provides a guide to prepare MaaXBoard 8ULP to boot up with the Verified Linux Package
and introduces how to use the functions of MaaXBoard 8ULP.

Chapter 2 Boot up System
MaaXBoard 8ULP supports boot up from eMMC, We will introduce how to program system images to
eMMC and boot from it in this chapter.
2.1 Program images into MaaXBoard 8ULP
2.1.1 Preparation for programming
1. Set SW1 Boot Switch on MaaXBoard-8ULP to Serial Download Mode:
1(CFG0)
2(CFG1)
3(CFG4)
4(MOD0)

2. Connect J7（USB0/POWER）and J4(USB for Debug) to PC USB port, connect J8 to a network cable.
3. Download the program tool uuu.exe from the network, The recommended website is:
https://github.com/nxp-imx/mfgtools/releases/tag/uuu_1.5.21
4. Put the built files: u-boot image, entire system image, and uuu.exe into a same folder.
After completing the preparations, take the following images as an example:
u-boot image: u-boot-maaxboard-8ulp.bin
entire system image: avnet-image-full-maaxboard-8ulp.wic
2.1.2 Only Program u-boot Image
1. Executing uuu.exe in Command Prompt, The specific commands are as follows:
MaaXBoard-8ULP-Linux-Yocto-UserManual-V3.0
https://www.avnet.com/wps/portal/us/products/avnet-boards/avnet-board-families/maaxboard/maaxboard-8ulp/
10
uuu -b emmc u-boot-maaxboard-8ulp.bin
2.1.3 Program Entire System Image
1. Executing uuu.exe in Command Prompt, The specific commands are as follows:
uuu -b emmc_all u-boot-maaxboard-8ulp.bin avnet-image-full-maaxboard-8ulp.wic
NOTE: To program the entire system image, the boot image must be programmed at the same time.
2.2 Boot from eMMC
Set SW1 Boot Switch on MaaXBoard-8ULP to Internal Boot Mode.
