【感芯科技64线程MC3172开发板免费试用体验】Fedora Linux 搭环境
这里我所用的环境是 Fedora Linux 36,KDE Plasma 桌面
MC3172介绍
厦门感芯科技多线程处理器 MC3172开发板,64线程同步并行运行,各个线程速度可按需配置,硬件级实时响应,无需中断服务程序,无需实时操作系统。RISC-V RV32IMC 指令集,100%单周期指令,133至200MHz主频,3.37coremark/MHz。极其适合高实时多并发应用场景。
下载交叉编译工具链
感芯科技官网上有开发资料
http://www.gxchip.cn/down/show-70.html
http://www.mounriver.com/download
选择 Linux,下载 MRS_Toolchain_Linux_x64_V1.50.tar.xz
解压到/home/nihui/osd/MRS_Toolchain_Linux_x64_V1.50
下载和编译 MC3172-CMake 例子
dreamcmi 已经配好了可以编译的 MC3172-CMake 工程
git clone https://github.com/dreamcmi/MC3172-CMake
修改 CMakeLists.txt 中的工具链设置
set(TOOLPATH "/home/nihui/osd/MRS_Toolchain_Linux_x64_V1.50/RISC-V Embedded GCC/bin/riscv-none-embed-")
cmake 常规的步骤编译
cd MC3172-CMake
mkdir build
cd build
cmake ..
make -j4
使用 wine 启动 MC3172 线程配置工具
fedora 安装 wine
su
dnf install wine
wine 启动线程配置工具,用法和 Windows 环境一致
cd MC3172-CMake/MC3172
wine 线程配置工具_V1.exe
下载和编译GX芯片下载工具 GX_ISPTool
https://gitee.com/gxchip/GX_ISPTool
生成makefile,编译报错找不到 hidapi
qmake-qt5 -makefile GX_ISPTool.pro
make -j4
fedora 安装依赖包 hidapi-devel
su
dnf install hidapi-devel
修改工程配置,链接库改为 hidapi-libusb,重新生成makefile编译通过
unix:!macx {
LIBS += -L$$_PRO_FILE_PWD_/hidapi/linux -lhidapi
}
unix:!macx {
LIBS += -L$$_PRO_FILE_PWD_/hidapi/linux -lhidapi-libusb
}
烧录固件,串口连接和测试
普通用户启动 GX-ISPTool,找不到 MC3172 设备,用 root 启动解决
su
./GX-ISPTool

root用户启动tio串口通讯,GX-ISPTool 中点击单次运行
su
tio /dev/ttyUSB0
至此已完全可以在纯Linux环境下开发应用了~
