Evaluation of MYIR's i.MX 8M Mini based SOM and EVM

The MYC-C8MMX CPU Moduleis designed by MYIR, which is an ARM embedded System-on-Module (SoM) based on NXP’ i.MX 8M Mini Quad Application Processor. The MYD-C8MMX development board is built around the MYC-C8MMX CPU Module, it is a complete evaluation module for your prototype and reference design. It is capable of running Linux and Android OS and provided with plenty of software resources. Typical applications are for Industry Control, Smart City, Smart Home, HMI, Internet of Things (IoT), etc.

Let’s see a video introduction of the MYD-C8MMX development board.

The MYC-C8MMX CPU Moduleis using the MIMX8MM6CVTKZAA (MIMX8MM6DVTLZAA) processor chip which is among the NXP i.MX 8M Mini family and combines advanced 14LPC FinFET process technology to provide more speed and improved power efficiency. It has a quad Cortex-A53 core which operates at speeds of up to 1.6 (1.8) GHz. It also has a general-purpose Cortex-M4 400 MHz core processor for low-power processing. Some parameters and target applications of the processor chip are listed below for reference.

The MYC-C8MMX CPU Module is a minimum system with PMIC, CPU, RAM (DDR4), Flash (eMMC, SPI Flash) and clock, plus an Ethernet PHY chip. A number of peripheral and IO signals are access through two 0.8mm pitch 100-pin board-to-board expansion connectors.

The MYD-C8MMX base board has mainly extended four parts:
1. Audio interface: added audio chip to extend Audio input and output interfaces

2. External power supply part: added one DC-DC power chip

3. Added one USB hub chip to extend 4 USB from the SoC USB interface, separately used for 4G LTE, two USB Host and one USB on expansion header.

4. Extend RTC module through I2C interface

Many other peripheral interfaces are brought out for user extension.

Among so many interfaces, Backlight, LVDS LCD and MIPI interface are relative to display function. The Backlight interface has 6 pins including two power signals, two GND and two GPIO (one is enabled terminal to control the backlight power and another is PWM to control the brightness of backlight.)

The two GPIO control terminals are from the GPIO1_01 and 08 of the i.MX 8M Mini.

The LVDS LCD and MIPI interface, total 3 interfaces are for display. But actually i.MX 8M Mini only has one MIPI DSI interface. The other two LVDS interfaces are switched from DSI through one DS12LVDS bridge chip, one is single link LVDS and another is dual link LVDS. So, we can only select MIPI DSI display or LVDS display. Also, we can only select single link LVDS or dual link LVDS.

MYIR offers optional LVDS based 7-inch LCD Module MY-LVDS070C including capacitive touch screen to work with the MYD-C8MMX board. The display resolution is up to 1024 by 600 pixels.

The MYD-C8MMX has one 2.0mm pitch 2*15-pin male expansion header. PDM and SAI are audio relative interfaces which are brought out from the expansion header.
