## 板级资源介绍
|
|||
|
|
|
|||
|
|
HPM6800EVK 是由先楫半导体推出的一款基于RISCV内核的开发板，带有丰富的片上资源和板上资源，可用于显示、音频和电机控制等应用。

## 使用说明
|
|||
|
|
|
|||
|
|
### 快速开始
|
|||
|
|
|
|||
|
|
本BSP支持通过`scons`命令来完成编译，在开始之前，需要先准备好开发所需的环境。
|
|||
|
|
|
|||
|
|
#### 准备环境
|
|||
|
|
- 步骤 1: 准备 [RT-Thread ENV](https://www.rt-thread.org/download.html#download-rt-thread-env-tool)
|
|||
|
|
- 步骤 2: 准备 [toolcahin](https://github.com/helloeagleyang/riscv32-gnu-toolchain-win/archive/2022.04.12.zip)
|
|||
|
|
- 下载并解压到指定的目录，如: `C:\DevTools\riscv32-gnu-toolchain`
|
|||
|
|
- 步骤 3: 设置环境变量： `RTT_RISCV_TOOLCHAIN` 为 `<TOOLCHAIN_DIR>\bin`， 如: `C:\DevTools\riscv32-gnu-toolchain\bin`
|
|||
|
|
- 步骤 4: 准备 [OpenOCD](https://github.com/hpmicro/rtt-debugger-support-package/archive/v0.4.0.zip)
|
|||
|
|
- 下载并解压到指定目录，如: `C:\DevTools\openocd-hpmicro`
|
|||
|
|
- 将 `OPENOCD_HPMICRO`环境变量设置为 `<OPENOCD_HPMICRO_DIR>\bin`，如： `C:\DevTools\openocd-hpmicro\bin`
|
|||
|
|
|
|||
|
|
#### 配置和构建工程
|
|||
|
|
|
|||
|
|
通过 RT-Thread ENV 命令行切换目录到当前BSP所在目录后，用户可以:
|
|||
|
|
|
|||
|
|
- 通过 `menuconfig` 命令 配置RT-Thread BSP的功能
|
|||
|
|
- 通过 `scons -jN` 命令完成构建, 其中`N` 最大值可以指定为CP拥有的物理内核数
|
|||
|
|
- 通过 `scons -c` 命令清除构建
|
|||
|
|
|
|||
|
|
#### 硬件连接
|
|||
|
|
|
|||
|
|
- 将BOOT 引脚拨到2'b00
|
|||
|
|
- 通过 TYPE-C线将板上的 `PWR_DEBUG` 连接到电脑
|
|||
|
|
|
|||
|
|
#### 下载 和 调试
|
|||
|
|
|
|||
|
|
- 通过如下命令完成下载:
|
|||
|
|
```console
|
|||
|
|
%OPENOCD_HPMICRO%\openocd.exe -f boards\debug_scripts\probes\ft2232.cfg -f boards\debug_scripts\soc\hpm6880.cfg -f boards\debug_scripts\boards\hpm6800evk.cfg -c "init; halt; flash write_image erase rtthread.elf; reset; shutdown"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
- 通过如下命令实现调试:
|
|||
|
|
|
|||
|
|
- 通过 `OpenOCD` 来连接开发板:
|
|||
|
|
```console
|
|||
|
|
%OPENOCD_HPMICRO%\openocd.exe -f boards\debug_scripts\probes\ft2232.cfg -f boards\debug_scripts\soc\hpm6880.cfg -f boards\debug_scripts\boards\hpm6800evk.cfg
|
|||
|
|
```
|
|||
|
|
- 通过 `GDB` 实现调试:
|
|||
|
|
```console
|
|||
|
|
%RTT_EXEC_PATH%\riscv32-unknown-elf-gdb.exe rtthread.elf
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
- 在`GDB Shell`中使用如下命令来加载和运行:
|
|||
|
|
|
|||
|
|
```console
|
|||
|
|
load
|
|||
|
|
c
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### **运行结果**
|
|||
|
|
|
|||
|
|
一旦成功下载，程序会自动运行并打印如下结果，板载LED灯会周期性闪烁。
|
|||
|
|
|
|||
|
|
配置好串口终端(串口配置为115200, 8-N-1),按复位键后，串口终端会打印如下日志：
