Get the product, cut the crap, open the box:

This paper makes a detailed test on each output interface of the MYD-JX8MX development board designed by the NXP i.MX8M series processor (to distinguish the NXP i.MX series, hereinafter referred to as the i.MX8 development board). The i.MX8 development board is an evaluation kit based on the MYC-JX8MX core board.

Using 12V/2A DC power supply, equipped with LCD (10.1inch single LVDS interface screen or 21.5in dual LVDS interface screen), dual camera, four-way USB3.0 interface, Ethernet, WIFI+BT, 4G module, audio, TF card, HDMI, three-way serial port, ESPI interface, M2 (PCIE interface) with SSD card, IO expansion and other functions, and provides driver support for Linux 4.9.88 operating system. Along with the development board, Mir Electronics also provides relevant materials including user manuals, backplane PDF schematics, peripheral drivers, BSP source packages, development tools and so on, providing developers with a stable design reference and a perfect software development environment, which can effectively help developers improve development efficiency, shorten development cycle, optimize design quality, and speed up product development and time to market.

The main interface resources of the development board are as follows:

The hardware block diagram of the development board is as follows:

Let's take a look at the close-up of some peripheral interfaces on the MYD-JX8MX development board: (the following interfaces are introduced from left to right)

12V DC input, HDMI, four-way USB3.0 interface, USB Type-C interface.

Audio output / input interface, Gigabit Ethernet interface, MicroSD card holder, SIM card holder.

Two-way camera interface, LVDS interface.

WiFi/BT interface, LED, LTE module interface.

Expansion interface, BooT dial switch, mechanical button.

ESPI interface, UART4 interface, UART2 interface, Debug interface.

All right, after the introduction of the hardware interface of the i.MX8 development board, we will analyze the core board and power-up test.
