|
||
|
||
**English** | [中文](README_zh.md)
|
||
|
||
## 1 Introduction
|
||
|
||
CH32V307V-R1 is a RISC-V core-based development board with a maximum main frequency of 144Mhz. It delivers the best value for developers to try and get started with RISC-V architecture.
|
||
|
||
This document records the execution instruction of the BSP (board support package) provided by the RT-Thread community for the CH32V307V-R1 development board.
|
||
|
||
The document is covered in three parts:
|
||
|
||
- Board Resources Introduction
|
||
- Compiling
|
||
- Quickly Get Started
|
||
|
||
By reading the Quickly Get Started section developers can quickly get their hands on this BSP and run RT-Thread on the board.
|
||
|
||
|
||
|
||
**Features**
|
||
|
||
- MCU: CH32V307VCT6, main frequency 144MHz，FLASH and RAM are available for configuration.
|
||
- LED: 2, user LEDs, LED1(blue), LED2(blue).
|
||
- Button: 2, Reset, User.
|
||
- USB: 2, Tpye-C.
|
||
- Network Port: 1, 10M PHY inside.
|
||
- WCH-Link download debugging tools onboard.
|
||
|
||
For more details about this board, please refer to: [CH32V307](https://www.wch.cn/products/CH32V307.html) and [CH32V307 official document](https://github.com/openwch/ch32v307)
|
||
|
||
## 2 Compiling
|
||
|
||
The BSP supports the RISC-V GCC development environment, here's the specific version information:
|
||
|
||
| IDE/Compiler | Version Tested |
|
||
| ------------ | -------------------- |
|
||
| GCC | WCH RISC-V GCC 8.2.0 |
|
||
|
||
## 3 Quickly Get Started
|
||
|
||
### 3.1 Using [Env](https://www.rt-thread.io/download.html?download=Env) to compile BSP
|
||
|
||
This section is about to introduce how to use Env to compile the BSP.
|
||
|
||
#### 3.1.1 Compile BSP
|
||
|
||
1. [Download WCH Compile Toolchain](https://github.com/NanjingQinheng/sdk-toolchain-RISC-V-GCC-WCH/releases)
|
||
2. [Download the Env tool latest version](https://github.com/RT-Thread/env-windows/releases)
|
||
3. [Download the RT-Thread latest code](https://github.com/RT-Thread/rt-thread/archive/refs/heads/master.zip)
|
||
4. Open the Env tool in the current BSP root directory and execute the `scons -j12 --exec-path=D:\sdk-toolchain-RISC-V-GCC-WCH-1.0.0\bin` command, compile it directly while specifying the toolchain location.
|
||
5. After compilation, the **rtthread.bin** file will be generated
|
||
|
||
|
||
|
||
#### 3.1.2 Hardware Connection
|
||
|
||
Use a data cable to connect the onboard wch-link to the PC, and turn on the power switch.
|
||
|
||
#### 3.1.3 Download
|
||
|
||
Open the WCH RISC-V MCU ProgrammerTool, select the **rtthread.bin** file that we just generated, and download it.
|
||
|
||
|
||
|
||
> Note that Chip Mem here is set to 224K ROM + 96K RAM.
|
||
|
||
#### 3.1.4 Running Result
|
||
|
||
In the terminal tool, open the onboard wch-link serial port (WCHDapLink SERIAL, default 115200-8-1-N), and after resetting the device, you can see the output information of RT-Thread on the serial port:
|
||
|
||
|
||
|
||
#### 3.1.5 If no running result
|
||
|
||
Replace download tool with WCH-LinkUtility.
|
||

|
||
|
||
### 3.2 Use VSCode to edit and compile the project
|
||
|
||
In the Env terminal, type command `scons --target=vsc` to generate the VSCode project. Then, type command `code .` in the Env terminal to open the VSCode.
|
||
|
||
Use **VSCode terminal** to type command `scons -j12 --exec-path=D:\sdk-toolchain-RISC-V-GCC-WCH-1.0.0\bin` to compile the project in VSCode.
|
||
|
||
|
||
|
||
<!-- ### 3.3 Import RT-Thread Studio Project
|
||
|
||
**CH32V307V-R1 is pending upgrade in Studio. It's not encouraged now to use Studio to compile this BSP.**
|
||
|
||
#### 3.3.1 Import
|
||
|
||
Open RT-Thread Studio and click: File-> Import:
|
||
|
||
|
||
|
||
Select "RT-Thread BSP Project into Workspace":
|
||
|
||
|
||
|
||
填写项目信息，Bsp 根目录为 \rt-thread\bsp\wch\risc-v\ch32v307v-r1 目录：
|
||
|
||
Fill in the project info, the BSP root directory is \rt-thread\bsp\wch\risc-v\ch32v307v-r1：
|
||
|
||
|
||
|
||
|
||
#### 3.3.2 Compilation Environment
|
||
|
||
工程导入后进行编译环境的设置，首先点击“打开构建设置”进入设置界面：
|
||
|
||
After the project is imported, set the compilation environment, click "Open Build Settings" to enter the setting interface:
|
||
|
||
|
||
|
||
将编译链路径复制到 Toolchain path 中：
|
||
Copy the compilation chain path into the Toolchain path:
|
||
|
||
|
||
|
||
Change Prefix:
|
||
|
||
|
||
|
||
Set the tool:
|
||
|
||
