Overview

The Renesas Starter Kit+ for RZ/T2M is an evaluation and development kit for the RZ/T2M MPU. The board is powered through a 5V input via a DC Power Jack or USB Type-C Connector.

  • On-board RZ/T2M MPU 320-pin (R9A07G075M24GBG)

  • Rich functional ICs such as Gigabit Ethernet PHY and Octal Flash are mounted, functions of target MPU can be fully evaluated

  • 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/T2M

  • Emulator circuit is mounted, can start program debugging by simply connecting USB cable to PC (two USB cables are bundled: one for emulator, and the other for power supply)

  • On-board memory components:

    • SDRAM (256MBit)
    • NOR Flash (256MBit)
    • Octa Flash (512MBit)
    • HyperRAM (512Mbit)
    • QSPI Serial Flash (512Mbit)
    • I2C EEPROM (32Kbit)

  • Communication interfaces include:

    • Debug interfaces (J-Link OB, MIPI-10, MIPI-20)
    • Ethernet
    • CAN
    • USB
    • RS485
    • UART
    • I2C
    • SPI

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 (pins K18, K19),
  • UART3 connected to the PMOD Header (J25, pins H16, G20),
  • LEDs defined as led0, led1, led2 and led3,

The Zephyr console uses UART0.

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the rzt2m_rsk board can be built in the usual way as documented in :ref:build_an_application.

To use J-Link OB on RSK+RZT2M,

  1. Open the jumper pin (J9) for switching the debug connection.

  2. Connect the micro-USB type-B to J-Link OB USB connector (J10), and then the LED4 is lighted.

Console

The UART port is accessed by USB-Serial port (CN16).

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: rzt2m_rsk/r9a07g075m24gbg/cr520 :goals: build debug

Flashing

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