Debugging not starts

Hi
I have struggled “a bit” with debug RP2040
Now i hav install VS code and PlatformIO on a new installation of WIN 10
and tried first with a BluePill “stm”
i can Download firmware to the chip use J-LINK EDU
but when Debugging the terminal ends with
Linking .pio\build\bluepill_f103c8\firmware.elf
Checking size .pio\build\bluepill_f103c8\firmware.elf
Advanced Memory Usage is available via “PlatformIO Home > Project Inspect”

Building .pio\build\bluepill_f103c8\firmware.bin
======================================== [SUCCESS] Took 18.68 seconds ========================================
and does not start Debug Consule the “icon” Debug close (cant put in picture)

and nothing in debug console (not starting debugger) can some come up with an input :wink:


platformio.ini
[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
build_type = debug
upload_protocol = jlink
debug_tool = jlink
debug_init_break = tbreak setup

Open a CLI and execute

pio debug --interface=gdb -x .pioinit

What is the output?

Yeah so it flashes it and starts, so that’s working.

This is now the third topic about debugging in which it works from the commandline but not via the VSCode GUI.

Hi and thanks for you reply
On my old WIN7 PC with an old Platformio and upgraded after install VS code 2022 (had VD code 2015 upgraded to 2022) it works
the problem with this came after I removed all VS code and Platformio because I had weird things in debug RP2040 then I could not debug so I thought format C: and completely fresh WIN10 and VS code and Platformio
maybe I should try with a VS code 2015?
can well see I’m not the only one

I’ve opened https://github.com/platformio/platformio-vscode-ide/issues/2925 about this but I cannot get a reproduction of the issue. I’m already at the lastest VSCode 1.64.0 version and have the newest PlatformIO extension and switched around the Microsoft C/C++ extension but it is still working.

Can you copy the VScode Help → About information and show a screenshot of your installed VSCode extensions with their exact versions?

I will when home and thanks for you time

It currently looks like it’s a problem with fresh PlatformIO installations and those using the builtin Python interpreter. Best to wait for an official solution as linked above.

In the meantime, I’ve modified my PlatformIO extension settings to not use the builtin Core and not use the portable Python interpreter, did a pip install platformio in my PC-global Python 3.8.6 installation, added the Scripts folder of my Python3 installation to my PATH and restarted VSCode; The PlatformIO extension will pick up this global PIO installation now and debugging works properly.

Thanks Max
I will see if a fix come

Please update the PlatformIO IDE extension to the latest version. Does it work now?

Hi Ivan
i think i have the newest (i have not used platformio for 2 years and just startet again)
the only old is i testet PY 3.9 and same problem with 3.10
Please tell me wath to upgrade you can see my extension list above

KR Henrik

You need to update the PlatformIO IDE extension in VSCode. This one PlatformIO IDE - Visual Studio Marketplace

Hi Ivan
Thanks it is now working on the STM 10 * to you for fast support
now I can try with RP2040 which was the one that started my uninstallation :wink:
because it behaved strangely with unknown stack.
Tests tomorrow and creates a new thread if teasing otherwise I write an ok here :wink:
