Overview

The Evaluation Board Kit for RZ/N2H is an evaluation and development kit for the RZ/N2H MPU. Since it has an on-board emulator, you can start evaluation by simply connecting the bundled cable with your PC. This board includes rich functional ICs such as Gigabit Ethernet PHY, non-volatile memory and LPDDR4 memory, and you can evaluate various functions of RZ/N2H without an extension board.

In addition, by expanding the inverter board, it is also possible to realize multi-axis motor control.

  • On-board RZ/N2H MPU 576-pin (R9A09G087M44GBG)

  • Rich functional ICs such as Gigabit Ethernet PHY, non-volatile memory (QSPI flash, Octa flash, eMMC) and DDR are mounted, functions of target MPU can be fully evaluated

  • Micro SD card slot, SD card slot and PCIe connector

  • Generic interface such as Pmod/Grove/QWIIC/mikroBUS

  • The pin header enables users to freely combine with the user's hardware system and evaluate RZ/N2H

  • Emulator circuit is mounted, can start program debugging by simply connecting USB cables: three USB cables are bundled for power supply (Type C, 15V), on-board emulator connection (Micro B) and terminal debugging (Mini B).

    • Please prepare USB PD power supply (45W = 15V-3A or more) by yourself.

  • Renesas IDE e² studio and FSP for RZ/N2 are available

Supported Features

.. zephyr:board-supported-hw::

Connections and IOs

By default, the board is configured for use with:

  • UART0 connected to the USB serial port (CN27),
  • LEDs defined as led8, led9, led10 and led11,

The Zephyr console uses UART0.

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the rzn2h_evb board can be built, flashed, and debugged in the usual way. See :ref:build_an_application and :ref:application_run for more details on building and running.

To use J-Link OB,

  1. Open the jumper pin (JP40) for switching the debug connection.

  2. Connect the micro-USB type-B to J-Link OB USB connector (CN26), and then the LED12 is lighted.

Console

The UART port is accessed by USB-Serial port (CN27).

Debugging

Here is an example for building and debugging with the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: rzn2h_evb/r9a09g087m44gbg/cr52_0 :goals: build debug

Flashing

Before using flash command, the board must be set to xSPI boot mode.
