## Introduction
|
|||
|
|
|
|||
|
|
This document provides brief introduction of the BSP (board support package) for the HPM6750EVKMINI development board.
|
|||
|
|
|
|||
|
|
The document consists of the following parts:

- Quickly Getting Started
|
|||
|
|
- Refreences
|
|||
|
|
|
|||
|
|
By reading the Quickly Get Started section developers can quickly get their hands on this BSP and run RT-Thread on the board. More advanced features will be introduced in the Advanced Features section to help developers take advantage of RT-Thread to drive more on-board resources.

|
## Board Resources Introduction
|
|||
|
|
|
|||
|
|
HPM6750EVKMINI is a development board based on the RISC-V core launched by HPMicro, with rich on-board resources and on-chip resources for Display, Audio， motor control，etc.

## Execution Instruction
|
|||
|
|
|
|||
|
|
### Quickly Getting Started
|
|||
|
|
|
|||
|
|
The BSP support being build via the 'scons' command, below is the steps of compiling the example via the 'scons' command
|
|||
|
|
|
|||
|
|
#### Parpare Environment
|
|||
|
|
- Step 1: Prepare [RT-Thread ENV](https://www.rt-thread.org/download.html#download-rt-thread-env-tool)
|
|||
|
|
- Step 2: Prepare [toolcahin](https://github.com/helloeagleyang/riscv32-gnu-toolchain-win/archive/2022.04.12.zip)
|
|||
|
|
- Download the package and extract it into a specified directory, for example: `C:\DevTools\riscv32-gnu-toolchain`
|
|||
|
|
- Step 3: Set environment variable `RTT_RISCV_TOOLCHAIN` to `<TOOLCHAIN_DIR>\bin`
|
|||
|
|
- For example: `C:\DevTools\riscv32-gnu-toolchain\bin`
|
|||
|
|
- Step 4: Prepare [OpenOCD](https://github.com/hpmicro/rtt-debugger-support-package/archive/v0.3.0.zip)
|
|||
|
|
- Download and extract it to specified directory, for example: `C:\DevTools\openocd-hpmicro`
|
|||
|
|
- Add `OpenOCD` environment variable `OPENOCD_HPMICRO` to `<OPENOCD_HPMICRO_DIR>\bin`
|
|||
|
|
- For example: `C:\DevTools\openocd-hpmicro\bin`
|
|||
|
|
|
|||
|
|
#### Configure and Build project
|
|||
|
|
|
|||
|
|
Open RT-Thread ENV command-line, and change directory to this BSP directory, then users can:
|
|||
|
|
|
|||
|
|
- Configure the project via `menuconfig` in `RT-Thread ENV`
|
|||
|
|
- Build the project using `scons -jN`, `N` equals to the number of CPU cores
|
|||
|
|
- Clean the project using `scons -c`
|
|||
|
|
|
|||
|
|
#### Hardware Connection
|
|||
|
|
|
|||
|
|
- Switch BOOT pin to 2'b00
|
|||
|
|
- Connect the `PWR_DEBUG` port to PC via TYPE-C cable
|
|||
|
|
|
|||
|
|
|
|||
|
|
#### Dowload / Debug
|
|||
|
|
|
|||
|
|
- Users can download the project via the below command:
|
|||
|
|
```console
|
|||
|
|
%OPENOCD_HPMICRO%\openocd.exe -f boards\debug_scripts\probes\ft2232.cfg -f boards\debug_scripts\soc\hpm6750-single-core.cfg -f boards\debug_scripts\boards\hpm6750evkmini.cfg -c "init; halt; flash write_image erase rtthread.elf; reset; shutdown"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
- Users can debug the project via the below command:
|
|||
|
|
|
|||
|
|
- Connect debugger via `OpenOCD`:
|
|||
|
|
|
|||
|
|
```console
|
|||
|
|
%OPENOCD_HPMICRO%\openocd.exe -f boards\debug_scripts\probes\ft2232.cfg -f boards\debug_scripts\soc\hpm6750-single-core.cfg -f boards\debug_scripts\boards\hpm6750evkmini.cfg
|
|||
|
|
```
|
|||
|
|
- Start Debugger via `GDB`:
|
|||
|
|
|
|||
|
|
```console
|
|||
|
|
%RTT_EXEC_PATH%\riscv32-unknown-elf-gdb.exe rtthread.elf
|
|||
|
|
```
|
|||
|
|
- In the `gdb shell`, type the following commands:
|
|||
|
|
|
|||
|
|
```console
|
|||
|
|
load
|
|||
|
|
c
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### **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:

|||
|
|
|
|||
