phyBOARD-Nash i.MX93 ####################

Overview

The phyBOARD-Nash is based on the phyCORE-i.MX93 SoM is based on the NXP i.MX93 SoC. It features common industrial interfaces and can be used as a reference for development or in the final product. It is an entry-level development board, which helps developers to get familiar with the module before investing a large amount of resources in more specific designs.

i.MX93 MPU is composed of one cluster of 2x Cortex-A55 cores and a single Cortex-M33 core. Zephyr OS is ported to run on one of the Cortex-A55 core as well as the Cortex-M33 core.

• Memory:

Supported Features

.. zephyr:board-supported-hw::

Devices

System Clock

This board configuration uses a system clock frequency of 24 MHz. Cortex-A55 Core runs up to 1.7 GHz. Cortex-M33 Core runs up to 200MHz in which SYSTICK runs on same frequency.

Serial Port

This board configuration uses a single serial communication channel with the CPU's UART2 for A55 core and M33 core. The u-boot bootloader or Linux use the second serial port for debug output.

Programming and Debugging (A55)

Copy the compiled zephyr.bin to the BOOT 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 execute zephyr.bin on Cortex-A55 Core0:

.. code-block:: console

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

Use this configuration to run basic Zephyr applications and kernel tests, for example:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: phyboard_nash/mimx9352/a55 :goals: build

Use this configuration to run basic Zephyr applications, for example:

.. code-block:: console

*** Booting Zephyr OS build v3.7.0-848-gb4d99b124c6d ***
Hello World! phyboard_nash/mimx9352/a55

Programming and Debugging (M33)

Copy the compiled zephyr.bin to the BOOT 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-M33 Core:

.. code-block:: console

load mmc 1:1 0x80000000 zephyr.bin;cp.b 0x80000000 0x201e0000 0x30000;bootaux 0x1ffe0000 0

Use this configuration to run basic Zephyr applications, for example:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: phyboard_nash/mimx9352/m33 :goals: build

This will build an image with the synchronization sample app, boot it and display the following console output:

.. code-block:: console

*** Booting Zephyr OS build v3.7.0-848-gb4d99b124c6d ***
Hello World! phyboard_nash/mimx9352/m33

Starting the M33-Core from U-Boot and Linux

Loading binaries and starting the M33-Core is supported from Linux via remoteproc. Please check the phyCORE-i.MX93 BSP Manual_ for more information.
