These lines are failing: https://github.com/ARMmbed/DAPLink/blob/master/tools/pre_build_script.py#L62

Can you run it again with some checks for lines 65 and 66 - what exceptions are you getting?

This is the result of running in vscode

I've noticed there might be an issue with paths , why are you executing the script from the exported files

C:\Users\User\Desktop\DAPLink-master\projectfiles\uvision\stm32f103xb_stm32f103rb_if>python ..\..\..\tools\pre_build_script.py

? Same for the second command. where are you located when you execute pre_build_script ? seems like where ever you are , its not valid for a script as it tries to get 3 folders up and there's no version_git.h file

@Aakrin Any update?

The solution is to disable the python file from running in MDK

Thanks for sharing. Considering this as resolved.

I have found this question too

I have found this question too

just run this 2line in pre_build_script.bat by your hand:
python %TOOLS%\pre_build_script.py
copy %DIR%\version_git_tmpl.txt %DIR%\version_git.h
and then delete it.
have not found better methond.

Use git clone to download this project, instead of downloading the ZIP file.
For me, this error was due to the execution failure of "git rev-parse --verify HEAD" in pre_build_script.py, line 68, which needs the .git folder.

I am the same, but I don’t know how to disable python. Please solve this problem. It has been bothering me for a long time.

@LONG300002 I assume this is again about git not python, clone the repo instead of downloading zip (you can verify it by running git command like git status to check if the repo is in correct state).
