使用 VSCode 搭配 xv6 qemu-gdb

VSCode launch.json

首先在 VSCode 新增一個 launch.json

​​​​"configurations": [
​​​​    {
​​​​        "name": "(lldb) Attach",
​​​​        "type": "cppdbg",
​​​​        "request": "launch",
​​​​        "MIMode": "gdb",
​​​​        "program": "${workspaceFolder}/kernel/kernel",
​​​​        "args": [],
​​​​        "miDebuggerServerAddress": "127.0.0.1:25501",
​​​​        "stopAtEntry": false,
​​​​        "cwd": "${workspaceFolder}",
​​​​        "miDebuggerPath": "/opt/homebrew/bin/riscv64-unknown-elf-gdb",
​​​​    },
​​​​]

program 填入 kernel 路徑
MIMode 選擇 gdb
miDebuggerServerAddress 根據 .gdbinit.tmpl-riscv 填入地址
miDebuggerPath 填入 riscv 版本 gdb 路徑，可用 whereis 尋找

Modify .gdbinit.tmpl-riscv

接著刪除

​​​​target remote 127.0.0.1:1234

否則會重複連線兩次
