I'm trying to debug an STM32 but when i try to launch the debugger, it comes up with the error in the image attached.

The following results are attempts with no local board.txt defined.

Here is the output when uploading using the STLink External 2.1 with OpenOCD method

Thanks for the report.

Can you confirm you are not using any entries in a local board.txt? (as the image shows that there are overrides present)

Please set the additional options as shown at the top of the page, and perform a full clean build and attach the output, so we can understand your environment in full.

Hi, email has been sent, the board.txt has been deleted. It was not present for the 2 compile outputs in the original post too

Cheers!

Thanks for the logs, and confirmation.

If you add the below property to the local board.txt file, it should allow the debugging to work as expected for this toolchain:
[code]runtime.tools.arm-none-eabi-gcc.path={runtime.tools.xpack-arm-none-eabi-gcc.path}[/code]

It's all working now, but i did have to put this back into the new boards.txt for it to work: [code] tools.stlinkv2.server.initCmd=-c "init"

Strangely there are now intellisense errors in the IDE, see attached the built in arduino F() and other classes are not being found too.

It seems like it has broken the arduino libraries somehow, see this in the built in delay() function

---

Can you try replacing the previous board.txt entry with the below:
[code]
# Comment this out --> runtime.tools.arm-none-eabi-gcc.path={runtime.tools.xpack-arm-none-eabi-gcc.path}
tools.stlinkv2.path={runtime.tools.xpack-arm-none-eabi-gcc.path}/bin
[/code]

This should more accurately override the debug command without affecting intellisense.

The Optimization option may need changing to debug the core functionality more accurately (on the vMicro > Debugger Menu)

Also if you Click vMicro > Show / Hide Hidden Files, this may improve the debugging experience.
