# EK-RA8M1 BSP Instruction

中文|[English](README.md)

## Introduction

Prepare for an exhilarating journey into the realm of the EK-RA8M1 development board! This guide is your treasure map, leading you to a trove of knowledge about the Board Support Package (BSP). The Quick Start section is your launchpad, propelling developers into action with the BSP, and getting RT-Thread operational on the development board faster than a speeding bullet.

Here’s a sneak peek of the adventure that awaits:

• A captivating exploration of the development board

• A practical and user-friendly BSP Quick Start Guide

## Hardware

The EK-RA8M1 evaluation board, developed based on the Renesas RA8M1 MCU, is a handy tool that allows users to easily evaluate the features of the RA8 MCU group. With flexible software package and IDE configurations, it’s a breeze to develop embedded system applications.

Here’s a sneak peek of what the front of the development board looks like:

### Peripheral Condition

Each peripheral supporting condition for this BSP is as follows:

| **On-chip Peripheral Drivers** | **Support** | **Remark** |
| :----------------: | :----------------: | :------------- |
| UART               | Support        | UART9 is the default log output port. |
| GPIO               | Support        |                |

## Instructions for Use 

The instructions for use are divided into the following two sections:

• Quick Start

This section is a user guide for newcomers to RT-Thread. By following simple steps, you can run the RT-Thread operating system on this development board and see the experimental results. 

• Advanced Use

This section is for developers who want to enable more development board resources on the RT-Thread operating system. By using the ENV tool to configure the BSP, you can enable more on-board resources and achieve more advanced functions.

### Quick Start 

This BSP currently only provides an MDK5 project. The following tutorial takes the MDK5 development environment as an example to introduce how to run the system.

**Compile and Download**

• Compile: Double-click the **project.uvprojx** file to open the MDK5 project and compile the program. 

• Download: Click the Debug button in MDK to download and debug 

**Running results**

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

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

```bash
initialize rti_board_start:0 done

initialize rti_board_end:0 done
initialize finsh_system_init:0 done

Hello RT-Thread!
msh >
```

**Entry function**

The entry function of the application layer is in **bsp\renesas\ra8m1-ek\src\hal_entry.c** in `void hal_entry(void)`. Source files that you created can be placed directly in the src directory.

```c
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);
    }
}
```

**ENV Configuration**

• How to use the ENV tool: [RT-Thread env tool user manual](https://www.rt-thread.io/document/site/programming-manual/env/env/). 

This BSP only enables the function of UART9 by default. If you're looking for more advanced functions such as components and software packages, ENV tool for configuration is available.

The steps are as follows:

1. Open the env tool under bsp.
2. Enter the `menuconfig` command to configure the project, and save and exit after configuration.
3. Enter the `pkgs --update` command to update the software package.
4. Enter the `scons --target=mdk5` command to regenerate the project.
