Renesas Starter Kit+ for RZ/N2L

Overview

Renesas Starter Kit+ for RZ/N2L is for evaluation or development using the RZ/N2L MPU. With the on-board emulator, you can start evaluation by simply connecting the bundled cable with your PC. This product has rich functional ICs such as Gigabit Ethernet PHY and Octal Flash, you can fully evaluate functions without an extension board.

  • On-board RZ/N2L MPU 225-pin (R9A07G084M04GBG)

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

  • Generic interfaces such as Pmod/Grove/Qwiic/mikroBUS

  • Pin headers for external extension enable you to evaluate many use cases

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

  • On-board memory components:

    • SDRAM (256MBit)

    • NOR Flash (256MBit)

    • Octa Flash (512MBit)

    • HyperRAM (64Mbit)

    • 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

Connections and IOs

By default, the board is configured for use with:

  • UART0 connected to the USB serial port (pins H15, G11),

  • UART3 connected to the PMOD Header (J25, pins E14, E15),

  • LEDs defined as led0, led1, led2 and led3,

The Zephyr console uses UART0.

Programming and Debugging

Applications for the rzn2l_rsk board can be built, flashed, and debugged in the usual way. See Building an Application and Run an Application for more details on building and running.

To use J-Link OB on RSK+RZN2L,

  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 Hello World application.

# From the root of the zephyr repository
west build -b rzn2l_rsk samples/hello_world
west debug

Flashing

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

# From the root of the zephyr repository
west build -b rzn2l_rsk samples/hello_world
west flash
