Overview

The i.MX95 EVK (IMX95LP4XEVK-15) board is a platform designed to show the most commonly used features of the i.MX 95 applications processor. It is an entry-level development board, which helps developers to get familiar with the processor before investing a large amount of resources in more specific designs. The i.MX 95 device on the board comes in a compact 15 x 15 mm package.

Hardware

  • i.MX 95 applications processor

    • The processor integrates up to six Arm Cortex-A55 cores, and supports functional safety with built-in Arm Cortex-M33 and -M7 cores

  • DRAM memory: 8-Gbit LPDDR4x DRAM

  • eMMC: 64 GB Micron eMMC

  • USB interface: Two USB ports: Type-A and Type-C

  • Audio codec interface

    • One audio codec WM8962B
    • One 3.5 mm 4-pole CTIA standard audio jack
    • One 4-pin connector to connect speaker

  • Ethernet interface

    • ENET2 controller

      • Supports 100 Mbit/s or 1000 Mbit/s RGMII Ethernet with one RJ45 connector connected with an external PHY, RTL8211

    • ENET1 controller

      • Supports 100 Mbit/s or 1000 Mbit/s RGMII Ethernet with one RJ45 connector connected with an external PHY, RTL8211

  • M.2 interface: One Wi-Fi/Bluetooth Murata Type-2EL module based on NXP AW612 chip supporting 1x1 Wi-Fi 6 and Bluetooth 5.3

  • MIPI CSI interface: Connects to one 22-pin or 36-pin miniSAS connector using x4 lane configuration

  • MIPI CSIDSI interface: Connects to one 36-pin miniSAS connector using x4 lane configuration

  • LVDS interface: two mini-SAS connectors each with x4-lane configuration

  • CAN interface: One 4-pin CAN headers for external connection

  • SD card interface: one 4-bit SD3.0 microSD card

  • I2C interface: I2C1 to I2C6 controllers

  • FT4232H I2C interface: PCT2075 temperature sensor and current monitoring devices

  • ADC interface: two 4-channel ADC header

  • Debug interface

    • One USB-to-UART/MPSSE device, FT4232H
    • One USB 2.0 Type-C connector (J31) for FT4232H provides quad serial ports

Supported Features

.. zephyr:board-supported-hw::

System Clock

This board configuration uses a system clock frequency of 24 MHz for Cortex-A55. Cortex-A55 Core runs up to 1.8 GHz.

Serial Port

This board configuration uses a single serial communication channel with the CPU's UART1 for Cortex-A55.

Programming and Debugging (A55)

Use this configuration to run basic Zephyr applications and kernel tests, for example, with the :zephyr:code-sample:synchronization sample:

  1. Build and run the Non-SMP application

.. zephyr-app-commands:: :zephyr-app: samples/synchronization :host-os: unix :board: imx95_evk_15x15/mimx9596/a55 :goals: build

This will build an image (zephyr.bin) with the synchronization sample app.

Copy the compiled zephyr.bin to the first FAT partition of the SD card and plug the SD card into the board. Power it up and stop the u-boot execution at prompt.

Use U-Boot to load and kick zephyr.bin to Cortex-A55 Core1:

.. code-block:: console

fatload mmc 1:1 0xd0000000 zephyr.bin; dcache flush; icache flush; cpu 1 release 0xd0000000

Or use the following command to kick zephyr.bin to Cortex-A55 Core0:

.. code-block:: console

fatload mmc 1:1 0xd0000000 zephyr.bin; dcache flush; icache flush; go 0xd0000000

It will display the following console output:

.. code-block:: console
