Set up environment

This section contains the steps to install the necessary components required to build and run a MCUXpresso SDK demo application, as supported by the MCUXpresso SDK.

Download the MfgTool

The Universal Upgrade Utility (UUU) is an upgraded version of MfgTool. It is a command line tool that aims at installing the bootloader to various storage including SD, QSPI, and so on, for i.MX series devices with ease.

The tool can be downloaded from github. Use version 1.2.135 or higher for full support for the M7 image. Download uuu.exe for Windows OS, or download UUU for Linux. Configure the path so that the executable can later be called anywhere in the command line.

Switch to Download Mode

The board needs to be in Download Mode mode for UUU to download images:

  1. Set the board boot mode to Download Mode [ SW1101:1000[1-4] ].

  2. Connect the development platform to your PC via USB cable between the SERIAL port and the PC USB connector. The SERIAL port is J301 on the base board.

  3. The PC recognizes the i.MX 8M Nano device as (VID:PID)=(1FC9:013E), as shown in Figure 1.
