Debugging Start (STM32)

[FerdinandEn]

``Type: Feature Request

OS and Version: Windows 11 VS Code Version: 1.88 CMSIS Solution 1.34.3

If I start debugging with the default settings (ARM debugger), no flash process is carried out. To start the flash process you have to execute Run. Can you give me a tip on how to adjust the entry in launch.json so that the device is flashed before the debugger is started.

launch.json

{ // 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": "Arm Debugger", "type": "arm-debugger", "request": "launch", "serialNumber": "${command:device-manager.getSerialNumber}", "program": "${command:arm-debugger.getApplicationFile}", // "cmsisPack": "${command:cmsis-csolution.getTargetPack}", // "deviceName": "${command:cmsis-csolution.getDeviceName}", "cmsisPack": "${command:device-manager.getDevicePack}", "deviceName": "${command:device-manager.getDeviceName}", "processorName": "${command:cmsis-csolution.getProcessorName}", "probe":"ST-Link", "programMode": "auto" } ] }

In VS Code you can chain tasks together or have a task run before a launch configuration.

In a task configuration the entry is:

"dependsOn": "some-pre-task"

and in launch configurations it's:

"preLaunchTask": "my-flash-task"

So you can create a flash/run task and set it to run before debug.

Hope this helps!

Thanks for your help. I have very little experience with the use of VSCode

I have modified my code

launch.json

{ // 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": "Arm Debugger", "type": "arm-debugger", "request": "launch", "serialNumber": "${command:device-manager.getSerialNumber}", "program": "${command:arm-debugger.getApplicationFile}", // "cmsisPack": "${command:cmsis-csolution.getTargetPack}", // "deviceName": "${command:cmsis-csolution.getDeviceName}", "cmsisPack": "${command:device-manager.getDevicePack}", "deviceName": "${command:device-manager.getDeviceName}", "processorName": "${command:cmsis-csolution.getProcessorName}", "preLaunchTask": "Flash Device", "probe":"ST-Link", "programMode": "auto" } ] ` }

and tasks.json

{ "version": "2.0.0", "tasks": [ { "type": "arm-debugger.flash", "serialNumber": "${command:device-manager.getSerialNumber}", "program": "${command:arm-debugger.getApplicationFile}", "cmsisPack": "${command:device-manager.getDevicePack}", "deviceName": "${command:cmsis-csolution.getDeviceName}", "processorName": "${command:cmsis-csolution.getProcessorName}", "problemMatcher": [], "label": "Flash Device", "probe": "ST-Link" } ] }

Now I got the following message

Addition:

I have just noticed that the problem only occurs when I start the debugger from the CMSIS view.

If you start the debugger from Run and Debug, everything works, including flashing.

@thegecko Thank you very much for your help

Yes, unfortunately there is a bug in VS Code which prevents these chains from running when executed programmatically:
