Introduction

This application note details how to use the UUU NXP Universal Update Utility for the i.MX platforms typically via SDP protocol, i.e. over USB OTG connection.

UUU is the replacement for MfgTool Command-line driven (no GUI). It allows a single command image download and it is fully scriptable. It supports all flash types (eMMC, NAND, QSPI, SD…).

Full open-source code is on Github with full documentation.

Build the UUU

The following instructions are used for building the uuu utility directly inside the DESK-MX8M-L-2.0.0-rc2 Virtual Machine

As reported in github README, the following Ubuntu packages have to be installed:

sudo apt-get install libusb-1.0-0-dev libbz2-dev libzstd-dev pkg-config cmake libssl-dev g++

then the git repository will be cloned:

git clone https://github.com/NXPmicro/mfgtools.git

For some Ubuntu 16.04 libzstd incompatibility, it is required to checkout a previous release:

git checkout uuu_1.4.201

Invoking the cmake utility, the application can be built:

cd mfgtools
cmake . && make

and install the application in the system directory:

sudo make install

MVM USB device

The USB device - for both SPL and u-boot stages - has to be enabled inside the VM using the VirtualBox proper Device menu. Once both USB devices are detected by the VM, it is possible to add them to the USB filters in order to enable them once detected:

MITO 8M Mini

MVM USB settings are displayed here below:

MITO8M Mini Evaluation Kit has to be configured wih:

• Boot configurations from SD card, i.e. with J32 jumper inserted
• no SD card inserted for boot from USB serial download instead of SD card
