Renesas Starter Kit+ for RZ/T2L

Overview

Renesas Starter Kit+ for RZ/T2L is an evaluation and development kit for the RZ/T2L MPU. By simply connecting the bundled cable to your PC, you can immediately start evaluation through an on-board emulator. This product contains rich functional ICs such as Gigabit Ethernet PHY and Octal Flash so you can evaluate various functions of the RZ/T2L without an extension board.

  • On-board RZ/T2L MPU 196-pin (R9A07G074M04GBG)

  • Rich functional ICs such as Gigabit Ethernet PHY and Octal Flash so you can evaluate various functions of the RZ/T2L without an extension board

  • 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:

    • Octa Flash (512MBit)

    • HyperRAM (64Mbit)

    • QSPI Serial Flash (128Mbit)

    • I2C EEPROM (16Kbit)

  • Communication interfaces include:

    • Debug interfaces (J-Link OB, MIPI-10, MIPI-20, Mictor-38)

    • 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 G12, G11),

  • UART2 connected to the PMOD Header (J25, pins M1, L2),

  • LEDs defined as led1 and led3,

The Zephyr console uses UART0.

Programming and Debugging

Applications for the rzt2l_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+RZT2L,

  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 LED6 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 rzt2l_rsk samples/hello_world
west debug

Flashing

Before using flash command, the board must be set to xSPI1 boot mode.

# From the root of the zephyr repository
west build -b rzt2l_rsk samples/hello_world
west flash
