[cpk-ra6m4 development board environment construction based on RT thread studio]

1. CPK-RA6M4 Development board features

Based on Reza RA6M4 MCU Developed CPK-RA6M4 MCU Evaluation board , adopt Flexible configuration of software packages and IDE, It can help users to RA6M4 MCU The characteristics of the group can be easily evaluated , And develop the embedded system application .

This article will use Renesas's CPK-RA6M4 The development board describes how to RA series MCU Up let RT-Thread Run up . The construction of the development environment will be divided into the following parts ：

• RA Development environment construction
• be based on RT-Thread Studio Development environment construction

2. RA Development environment construction

2.1 Essential tools

2.1.1 Flexible configuration software package (FSP) ：

It can quickly configure the peripheral functions of the development board , Please use v3.5.0 edition , It's available at github Upload and download 3.5.0 edition （ Download address ：https://github.com/renesas/fsp/releases/tag/v3.5.0 , Note that the file name is ：setup_fsp_v3_5_0_rasc_v2021-10.exe）

< Note that the official website is 3.8.0 edition , Not forward compatible , Use 3.8.0 Version will make the project unavailable >

2.1.2 CPK-RA6M4 Board level support package ：

coordination FSP Use it together , It is the graphical configuration support package of the development board , Please use v3.5.0 edition

Can be found in Renesas Download from the official website ：

Online disk download link ：https://cowtransfer.com/s/b9eddec169d544
Included Above FSP Software and FSP Board level support package , Download from this link in one step .

2.2 Environment building

Flexible configuration software package (FSP)

1、 Open the link to download FSP, Please confirm the downloaded 3.5.0 edition , This download step can be ignored when downloading from the network disk .

at present RT-Thread in CPK-RA6M4 Of BSP The supported versions are 3.5.0. Can be in BSP Of README Confirm the currently supported FSP edition .
2、 Find the downloaded file and open （ Note that the file name contains rasc）：setup_fsp_v3_5_0_rasc_v2021-10.exe

3、 Configure the installation path , Find this path after installation , Then add CPK-RA6M4 Board level support package You will use

4、 Check Licenese

5、 Click on install Wait for installation to complete .

6、 function rasc.exe, Verify that the installation was successful . route ：\eclipse\rasc.exe

7、 After successful startup, it can be closed , Continue with the next operation

2.3 CPK-RA6M4 Board level support package

1、 This part , You can refer to Renesas Official document 《 towards FSP Add CPK Evaluation Board BSP 》
download 3.5.0 Version support package . This download step can be ignored when downloading from the network disk .

2、 The following three files can be found in the downloaded support package

3、 Now find FSP Installation path for , Get into \internal\projectgen\ra\ , Copy the file to the corresponding folder .

4、 Open again rasc.exe, See if it is added successfully . Click on next Enter project creation

5、 Confirm whether there are added CPK-RA6M4 Development board support package , This step is only to verify whether the addition is successful , There is no need to continue creating the project , Can be closed .

6、 So far, the environment related to the Reza development board has been basically set up . The debugger J-link Installation , In the following steps .

3. RT-Thread Development environment construction

3.1 be based on RT-Thread studio

Download and install the prerequisite software environment

• Download and install RT-Thread studio
• open RT-Thread studio, Enter the package manager , download RT-Thread Of bsp Support package and related tools .

download BSP Support package , Check the latest version .

PS:BSP The support package will automatically download the dependent resource package ：

• RT-Thread System source code package
• GCC Tool chain ： edition 10.2.1
• The debugger J-link： edition 7.50a

3.2 Create engineering test results

1、 open RT-Thread studio, newly build RT-Thread project —> Based on the development board , establish CPK-RA6M4 The engineering of

2、 Open the created project , double-click RA Smart Configurator You can open the just installed FSP Configuration tool picture

3、 The first time you open it, you need to configure FSP route , Select the installation path . Confirm to open FSP You can shut down , Do not make any changes to continue with the subsequent operations .

4、 Compiler Engineering , Confirm that the tool chain is configured correctly

5、 connection ： Connect serial port tools 、USB-Jlink ( Jump cap back to normal operation as well as device mode)

6、 Connect UART7 （TX:P613; RX:P614）, Baud rate 115200. This serial port is used for RT-Thread System command line interaction .

7、 Download the program to the development board , Note that the download is HEX file .

• View the run results

After downloading the program successfully , The system will automatically run and print system information . Connect the corresponding serial port of the development board to PC , Open the corresponding serial port in the terminal tool （115200-8-1-N）, After resetting the device , You can see RT-Thread Output information of . Input help Command to view the commands supported in the system .
On board LED3 Will 1Hz Frequency flicker

• Turn on the oscilloscope
  
• On board reset, View relevant built-in information
  
• The results are as follows

8、 Application entry function

• The entry function of the application layer is in bsp\ra6m4-cpk\src\hal_emtry.c in Of void hal_entry(void) . The source file written by the user can be directly placed in src Under the table of contents .

void hal_entry(void)
{
    
    rt_kprintf("\nHello RT-Thread!\n");    while (1)
    {
    
        rt_pin_write(LED3_PIN, PIN_HIGH);
        rt_thread_mdelay(500);
        rt_pin_write(LED3_PIN, PIN_LOW);
        rt_thread_mdelay(500);
    }
}

• main.c In the project folder re_ge Next
  

/* generated main source file - do not edit */
#include "hal_data.h"
            int main(void) {
    
              hal_entry();
              return 0;
            }
