VSCode + QEMU-gdb

###### tags: `6.1810`

# 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
