XuanTie - R920 Series
一 简介
1. 内核
暂无。
2.特点
暂无。
3.BSP支持情况
-
当前BSP支持下述内核：
r920 -
当前BSP默认设置的内核是r920，该架构支持[F][D][V]扩展。
-
当需要使用SMP多核时，请使用
scons --menuconfig使能SMP功能并配置CPU个数。
4.运行QEMU
-
BSP根目录下存在
qemu.bat脚本，生成可执行文件后可点击该脚本直接启动QEMU. -
Linux用户可以直接使用
qemu-system-riscv64命令启动QEMU.
qemu-system-riscv64 -machine xiaohui -smp cpus=2 -nographic -kernel rtthread.elf -cpu r920
二 工具
- 编译器： https://www.xrvm.cn/community/download?id=4433353576298909696
- 模拟器： https://www.xrvm.cn/community/download?id=4397435198627713024
注：若上述链接中的编译器与模拟器不能使用，可以使用下述CDK中的编译器与模拟器
三 调试方法
下述调试方法以E906举例，本BSP操作方式一致，搭建完成RT-Thread开发环境，在BSP根目录使用env工具在当前目录打开env。
使用前执行一次menuconfig命令，更新rtconfig.h配置，然后在当前目录执行scons -j12命令编译生成可可执行文件。
下述是使用vscode调试的展示。
一起为RISC-V加油！
