esp-idf vscode debug command 'espIdf.getXtensaGdb' not found

esp32 idf vscode debug错误

vscode中配置文件采用的是正点原子的，调用gdb的时候，提示报错，找不到相应的命令
launch.json文件中gdb的配置如下

{
  "version": "0.2.0",
  "configurations": [ 
	{ 
		"name": "GDB", 
		"type": "cppdbg", 
		"request": "launch", 
		"MIMode": "gdb", 
		"miDebuggerPath": "${command:espIdf.getXtensaGdb}", 
		"program": "${workspaceFolder}/build/${command:espIdf.getProjectName}.elf", 
		"windows": { 
		"program": "${workspaceFolder}\\build\\${command:espIdf.getProjectName}.elf" 
		}, 
		"cwd": "${workspaceFolder}", 
		"environment": [{ "name": "PATH", "value": "${config:idf.customExtraPaths}" }], 
		"setupCommands": [ 
		{ "text": "target remote :3333" }, 
		{ "text": "set remote hardware-watchpoint-limit 2"}, 
		{ "text": "mon reset halt" }, 
		{ "text": "thb app_main" }, 
		{ "text": "flushregs" } ], 
		"externalConsole": false, 
		"logging": { 
		"engineLogging": true 
		} 
	} 
	]
}

主要问题出现在这句配置"miDebuggerPath": "${command:espIdf.getXtensaGdb}", 错误提示如下

原因应该是路径不对或者命令不对

手动配置绝对路径也不无法正常debug

查看esp-idf 文档中
发现官方是这样配置如下

{
  "configurations": [
    {
      "type": "gdbtarget",
      "request": "attach",
      "name": "Eclipse CDT Remote",
      "program": "${workspaceFolder}/build/${command:espIdf.getProjectName}.elf",
      "initCommands": [
        "set remote hardware-watchpoint-limit {IDF_TARGET_CPU_WATCHPOINT_NUM}",
        "mon reset halt",
        "maintenance flush register-cache"
      ],
      "gdb": "${command:espIdf.getToolchainGdb}",
      "target": {
        "connectCommands": [
          "set remotetimeout 20",
          "-target-select extended-remote localhost:3333"
        ]
      }
    }
  ]
}

gdb配置如下，就可以正常debug了

"gdb": "${command:espIdf.getToolchainGdb}",

完整配置launch.json

{
  "version": "0.2.0",
  "configurations": [ 
	{ 
		"name": "GDB", 
		"type": "cppdbg", 
		"request": "launch", 
		"MIMode": "gdb", 
		"miDebuggerPath": "${command:espIdf.getToolchainGdb}",
		"program": "${workspaceFolder}/build/${command:espIdf.getProjectName}.elf", 
		"windows": { 
		"program": "${workspaceFolder}\\build\\${command:espIdf.getProjectName}.elf" 
		}, 
		"cwd": "${workspaceFolder}", 
		"environment": [{ "name": "PATH", "value": "${config:idf.customExtraPaths}" }], 
		"setupCommands": [ 
		{ "text": "target remote :3333" }, 
		{ "text": "set remote hardware-watchpoint-limit 2"}, 
		{ "text": "mon reset halt" }, 
		{ "text": "thb app_main" }, 
		{ "text": "flushregs" } ], 
		"externalConsole": false, 
		"logging": { 
		"engineLogging": true 
		} 
	} 
	]
}
