Introduction
This document provides an overview of the HPMicro BSPs (Board Support Package) available in the RT-Thread repository. Each BSP is tailored for specific HPMicro development boards, offering necessary drivers and configurations to run RT-Thread seamlessly on RISC-V based HPMicro microcontrollers.
The document consists of the following parts:
- HPMicro BSP Overview
- Available BSPs
- Quick Start Guide
- Common Development Environment Setup

Quick Start Guide
Prerequisites
Before getting started with any HPMicro BSP, you need to prepare the following development environment:
1. RT-Thread ENV
- Download and install RT-Thread ENV
2. RISC-V Toolchain
- Download the RISC-V toolchain: riscv32-gnu-toolchain
- Extract it to a specified directory, for example:
C:\DevTools\riscv32-gnu-toolchain - Set environment variable
RTT_RISCV_TOOLCHAINto<TOOLCHAIN_DIR>\bin- For example:
C:\DevTools\riscv32-gnu-toolchain\bin
- For example:
3. OpenOCD for HPMicro
- Download OpenOCD: rtt-debugger-support-package
- Extract it to a specified directory, for example:
C:\DevTools\openocd-hpmicro - Set environment variable
OPENOCD_HPMICROto<OPENOCD_HPMICRO_DIR>\bin- For example:
C:\DevTools\openocd-hpmicro\bin
- For example:
Getting Started with a Specific BSP
-
Navigate to the desired BSP directory:
cd rt-thread/bsp/hpmicro/<bsp_name> -
Configure the project:
- Open RT-Thread ENV command-line
- Change directory to the BSP directory
- Run
menuconfigto configure the project
-
Build the project:
scons -jN # N equals to the number of CPU cores -
Hardware Connection:
- Switch BOOT pin to 2'b00
- Connect the
PWR_DEBUGport to PC via TYPE-C cable
-
Download and Debug:
- Use the provided OpenOCD scripts for downloading and debugging
- Refer to individual BSP README files for specific commands
Running Results
Once the project is successfully downloaded, the system runs automatically. The LED on the board will flash periodically.
Connect the serial port of the board to the PC, communicate with it via a serial terminal tool (115200-8-1-N). Reset the board and the startup information of RT-Thread will be observed:
