Renesas RSK-RZT2M Development Board BSP Guide

English | 中文

Introduction

This document provides the Board Support Package (BSP) guide for the Renesas RSK-RZT2M development board. By reading the quick start section, developers can quickly get started with this BSP and run RT-Thread on the development board.

The main contents are as follows:

• Board introduction
• BSP quick start guide

Board Introduction

The RSK-RZT2M MCU evaluation board, based on the Renesas RZ/T2M development, is designed to assist users in evaluating the features of the RA6M4 MCU group and developing embedded system applications through flexible configuration of software packages and IDEs.

The front appearance of the development board is as follows:

The commonly used on-board resources of this development board are as follows:

• MCU: R9A07G075M24GBG, with a maximum operating frequency of 800MHz, dual Arm Cortex®-R52 cores, tightly coupled memory 576KB (with ECC), internal RAM 2 MB (with ECC)
• Debug interface: On-board J-Link interface
• Expansion interface: Two PMOD connectors

Usage Guide

The usage guide is divided into the following two sections:

• Quick Start

  This section is prepared for beginners who are new to RT-Thread. Follow simple steps to run the RT-Thread operating system on this development board and see experimental results.

• Advanced Usage

  This section is prepared for developers who need to utilize more development board resources on the RT-Thread operating system. By using the ENV tool to configure the BSP, more on-board resources can be enabled to achieve more advanced functionalities.

Quick Start

Currently, this BSP only provides an IAR project. Below is an example of how to get the system up and running using IAR Embedded Workbench for Arm development environment.

Hardware Connection

Connect the development board to the PC using a USB data cable and use the J-link interface for downloading and debugging programs.

Compilation and Download

• Navigate to the bsp directory, open ENV, and use the command scons --target=iar to generate an IAR project.
• Compilation: Double-click the project.eww file to open the IAR project and compile the program.
• Debugging: Click Project->Download and Debug on the top-left navigation bar of IAR to download and start debugging.

Viewing Execution Results

After successfully downloading the program, the system will automatically run and print system information.

Connect the corresponding serial port of the development board to the PC, open the terminal tool, and select the corresponding serial port (115200-8-1-N). After resetting the device, you can see the output information from RT-Thread. Enter the help command to view the supported commands in the system.

Application Entry Function

The entry function of the application layer is in src\hal_entry.c under void hal_entry(void). User-written source files can be directly placed in the src directory.

void hal_entry(void)
{
    rt_kprintf("\nHello RT-Thread!\n");
    rt_kprintf("==================================================\n");
    rt_kprintf("This is a iar project which mode is ram execution!\n");
    rt_kprintf("==================================================\n");

    while (1)
    {
        rt_pin_write(LED_PIN, PIN_HIGH);
        rt_thread_mdelay(500);
        rt_pin_write(LED_PIN, PIN_LOW);
        rt_thread_mdelay(500);
    }
}

FSP Configuration

To modify Renesas BSP peripheral configurations or add new peripheral ports, the Renesas Flexible Software Package (FSP) configuration tool is required. Please follow the steps below for configuration. For any configuration issues, feel free to ask in the RT-Thread Community Forum.

1. Download Flexible Software Package (FSP) | Renesas, please use FSP version 1.3.0.

2. Refer to the document How to import the board support package on how to add the "RSK-RZT2M board support package" to FSP.

3. Refer to the document: RA Series Using FSP to Configure Peripheral Drivers.

ENV Configuration

• How to use the ENV tool: RT-Thread env tool user manual

This BSP only enables the UART1 function by default. If you need to use more advanced features such as components, software packages, etc., you need to configure it using the ENV tool.

The steps are as follows:

1. Open the env tool under bsp.
2. Enter the menuconfig command to configure the project, save and exit after configuration.
3. Enter the pkgs --update command to update the software packages.
4. Enter the scons --target=iar command to regenerate the project.
