1、vscode启动debug窗口

按Ctrl+Shift+D,打开Debug窗口

默认是“No configurations”, 点击“F5”,会提示你配置GDB参数(选择gcc build and debug active file),配置文件名称为launch.json(配置参考3)

配置完成后,再按F5, 会提示配置GCC,选择“Configure Task”, 选择“C/C++: build and debug active file”, 配置文件名称为task.json(配置参考2)

2、GCC配置

{    // See https://go.microsoft.com/fwlink/?LinkId=733558     // for the documentation about the tasks.json format    "version": "2.0.0",    "tasks": [        {            "type": "shell",            "label": "gcc build active file",            "command": "/usr/share/mips-gcc-4.6/staging_dir/bin/mips-linux-gcc",            "args": [                "-g",                "${file}",                "-o",                "${fileDirname}/${fileBasenameNoExtension}"            ],            "options": {                "cwd": "/usr/bin"            },            "problemMatcher": [                "$gcc"            ]        }    ]}

“command”: 编译链的地址

3、GDB配置

{    // Use IntelliSense to learn about possible attributes.    // Hover to view descriptions of existing attributes.    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387    "version": "0.2.0",    "configurations": [        {            "name": "gcc build and debug active file",            "type": "cppdbg",            "request": "launch",            "miDebuggerServerAddress": "192.168.0.1:10000",            "program": "/home/renyinshan/work/p53/apps/cmdlib/test",            "args": [],            "stopAtEntry": true,            "cwd": "/home/renyinshan/work/p53/apps/cmdlib/",            "environment": [],            "externalConsole": false,            "MIMode": "gdb",            "setupCommands": [                {                    "description": "Enable pretty-printing for gdb",                    "text": "-enable-pretty-printing",                    "ignoreFailures": true                }            ],            "preLaunchTask": "gcc build active file",            "miDebuggerPath": "/home/renyinshan/work/p53/apps/gdb/install/bin/mips-linux-gdb"        }    ]}

“program”: 要调试的程序名(包含路径,最好绝对路径,免得麻烦)

“miDebuggerServerAddress”: 服务器的地址和端口

“cwd”: 调试程度的路径

“miDebuggerPath”: gdb的路径

4、GDB server编译及运行

1)编译

P53编译时,请打开如下开关; P59需要从编译链目录拷贝一个。

scripts/tozedap-router_4g_industry/config.tozedap-router_4g_industry:564:export NO_CPP_LIB=0GDB运行需要libstdc++.so.6的库,所以需要把此开关打开。
./cool 3 gdb_build等待完成即可

编译完成后的文件如下:

renyinshan@renyinshan:~/work/p53/build$ ls ../apps/gdb/install/*../apps/gdb/install/bin:mips-linux-gdb  mips-linux-gdb-add-index  mips-linux-run../apps/gdb/install/include:gdb../apps/gdb/install/lib:libmips-linux-sim.a../apps/gdb/install/share:gdb  info  locale  manrenyinshan@renyinshan:~/work/p53/build$ ls ../apps/gdb/installgdbserver/bin/mips-linux-gdbserverrenyinshan@renyinshan:~/work/p53/build$

说明:

install/bin 目录的mips-linux-gdb为vscode中配置需要的;

installgdbserver/bin/ 目录中的mips-linux-gdbserver,需要拷贝到板子中;

2)ssh登录设备,下载gdbserver到/tmp目录中, 并增加+x权限

3)ssh登录设备,下载可执行程序到/tmp目录中, 并增加+x权限

4)运行

/tmp # ./mips-linux-gdbserver :10000 ./test调试输出:/tmp # ./mips-linux-gdbserver :10000 test Process /tmp/test created; pid = 22608Listening on port 10000Remote debugging from host 192.168.0.245APP is running!

备注说明:1) 下载的可执行程序,必须保证是设备所需编译链编译的;2) vscode中按F5调试时,GCC编译的配置和GDB参考1和2;

5、调试

准备完成, 在VSCode进行调试。
