安装 JLINK
下载安装后找到安装路径下的可执行文件
将此路径添加到环境变量的 Path 中。
创建 JFlash 项目
打开 JFlash，选择新建项目
选择单片机型号
在弹出的窗口中搜索单片机
其他参数根据实际情况填写
新建完成：
接下来设置一下项目
把 Start Application 勾上，复位方式选择通过复位引脚复位。如果没有这个硬件条件则使用软件复位。
最后保存工程
编写 powershell 脚本
新建一个脚本叫 jlink-release-download.ps1
powershell
# 项目参数
$project_name = "test"
$cmake_config = "gcc-release"
$project_path = Split-Path -Path $MyInvocation.MyCommand.Definition -Parent
$workspace_path = Split-Path $project_path -Parent
$build_path = "$workspace_path/out/build/$cmake_config"
$install_path = "$workspace_path/out/install/$cmake_config"
# 开始操作
New-Item -Path $build_path -ItemType Directory -Force
Push-Location $build_path
try
{
cmake -G "Ninja" $workspace_path `
--preset "$cmake_config"
if ($LASTEXITCODE)
{
throw "配置失败"
}
ninja -j12
if ($LASTEXITCODE)
{
throw "编译失败"
}
ninja install
}
finally
{
Pop-Location
}
Push-Location $install_path
try
{
arm-none-eabi-objcopy -O binary `
"$install_path/bin/${project_name}.elf" `
"$install_path/bin/${project_name}.bin"
$jflash_arg_array = @(
"-openprj${workspace_path}/jflash-project.jflash",
"-open${install_path}/bin/${project_name}.bin,0x8000000",
"-auto",
"-startapp",
"-exit"
)
$jflash_arg = $jflash_arg_array -join " "
$jflash_arg = $jflash_arg.Trim()
Write-Host $jflash_arg
Start-Process -FilePath "JFlash.exe" `
-ArgumentList $jflash_arg `
-WindowStyle Normal `
-Wait
if ($LASTEXITCODE)
{
throw "将 ${project_name}.bin 下载到单片机失败。"
}
Write-Host "将 ${project_name}.bin 下载到单片机成功。"
}
finally
{
Pop-Location
}项目参数部分根据实际情况修改。
为 DEBUG 配置也创建一个 powershell 脚本，叫作 jlink-debug-download.ps1
powershell
# 项目参数
$project_name = "test"
$cmake_config = "gcc-debug"
$project_path = Split-Path -Path $MyInvocation.MyCommand.Definition -Parent
$workspace_path = Split-Path $project_path -Parent
$build_path = "$workspace_path/out/build/$cmake_config"
$install_path = "$workspace_path/out/install/$cmake_config"
# 开始操作
New-Item -Path $build_path -ItemType Directory -Force
Push-Location $build_path
try
{
cmake -G "Ninja" $workspace_path `
--preset "$cmake_config"
if ($LASTEXITCODE)
{
throw "配置失败"
}
ninja -j12
if ($LASTEXITCODE)
{
throw "编译失败"
}
ninja install
}
finally
{
Pop-Location
}
Push-Location $install_path
try
{
arm-none-eabi-objcopy -O binary `
"$install_path/bin/${project_name}.elf" `
"$install_path/bin/${project_name}.bin"
$jflash_arg_array = @(
"-openprj${workspace_path}/jflash-project.jflash",
"-open${install_path}/bin/${project_name}.bin,0x8000000",
"-auto",
"-startapp",
"-exit"
)
$jflash_arg = $jflash_arg_array -join " "
$jflash_arg = $jflash_arg.Trim()
Write-Host $jflash_arg
Start-Process -FilePath "JFlash.exe" `
-ArgumentList $jflash_arg `
-WindowStyle Normal `
-Wait
if ($LASTEXITCODE)
{
throw "将 ${project_name}.bin 下载到单片机失败。"
}
Write-Host "将 ${project_name}.bin 下载到单片机成功。"
}
finally
{
Pop-Location
}创建 task.json
在 vscode 项目根目录下的 .vscode 目录创建 task.json 文件
填入以下内容：
json
{
"version": "2.0.0",
"tasks": [
{
"label": "stflash-release-download",
"type": "shell",
"command": "pwsh",
"args": [
"./stflash-release-download.ps1"
],
"options": {
"cwd": "${workspaceFolder}/test"
},
"problemMatcher": []
},
{
"label": "stflash-debug-download",
"type": "shell",
"command": "pwsh",
"args": [
"./stflash-debug-download.ps1"
],
"options": {
"cwd": "${workspaceFolder}/test"
},
"problemMatcher": []
},
{
"label": "jlink-debug-download",
"type": "shell",
"command": "pwsh",
"args": [
"./jlink-debug-download.ps1"
],
"options": {
"cwd": "${workspaceFolder}/test"
},
"problemMatcher": []
},
{
"label": "jlink-release-download",
"type": "shell",
"command": "pwsh",
"args": [
"./jlink-release-download.ps1"
],
"options": {
"cwd": "${workspaceFolder}/test"
},
"problemMatcher": []
},
],
}args是传递给 pwsh 进程的参数，向它传递 ps1 文件。cwd是启动 pwsh 进程时赋予它的当前路径，将它改成刚刚创建的 ps1 文件所在的目录。
创建 launch.json
在 vscode 项目根目录的 .vscode 目录创建 launch.json 文件
填入以下内容
json

}CMakePresets.json
附上我的 CMakePresets.json 文件的内容。这不是本文要讲述的。本文只讲述如何在已经配置好 cmake 和 GNU 工具链的情况下配置 JLINK
