Bus signal extraction not working

[Seaeo]

Hello,

I come to you after several exchange with CSS electronic support who promotes your SW and from who I know it.

The main description of my problem is the following: when I open an MDF raw file and try to Extract bus signal with an appropriate DBC, there is no file created (windows explorer sees an activity but with a file of 0bit)

I am using the following version of asammdf:
version 8.2.5.dev5
PySide6 6.8.2.1
CPython 3.12.9 x64

Up to know, we did the following test with the help of CSS support:
Laptop "A" (HP Probook 450 G10 Win11 25H2)

• Laptop "A":The initial configuration is with asammdf files on windows desk and MF4/ dbc files on a folder which is synced with a NAS (with Qsync from Qnap). You can see what happen on the video here: https://drive.google.com/file/d/11hjQTeYUdK5krVLCqso4ZJlAYytpiepK/view?usp=sharing

• Laptop "A": I was advised to try after reloading the dbc file: same problem

• Laptop "A":After this we tried the same test on my side and on CSS support side with exactly the same files. the files are available here https://drive.google.com/drive/folders/1sdW_Ye6rsdgAHDmXlD0Bgt1qUGkIGGIu?usp=sharing
  The result is there is the problem on my laptop and not on CSS support side

• Laptop "A":After a discussion concerning the file system and potential problems on synced folders, I tried with asammdf / MF4 / dbc files in c:/temp: same problem

• Laptop "A": We tried another time with asammdf / MF4 / dbc files in MyDocs/temp: same problem

• Laptop "B" To have another view, I tried on another laptop let's call it "B" (HP Probook 450 G5 Win11 25H2): it works

• Precision concerning laptops differences:

  • I am admin of both laptops and I launch asammdf as admin
  • on a file system / drive / sync point of view, both laptops have the same configuration. The main difference on that point is that on Laptop A my first attempt was using the synchronised folders while on Laptop B , my first attempt was on a not synchronised folder. "I didn't tried on a synchronised folder on laptop B
  • the main differences between laptops are:
    • Age / Version:
      • HP Probook 450G10 2023 (the one with the problem)
      • HP Probook 450G5 2018 (the one on which it works)
    • SW installed: The main points that I could see a link (I am not a specialist, may it have an impact ?) are
      • Microsoft Visual Studio Code and some python libraries
      • Python 3.13.7
      • Python launcher
      • Thonny 4.1.7
      • Vector Candb++ ??

• Laptop "A". After this, I came back on Laptop A and tried different functions saving a file on the PC:

  • I tried to save the configuration through asmmdf in the same folder (mydocument/temp) and it works.
  • I tried to export through the "Bus Logging" Tab and it doesnot work (not "Bus Extract Signals" but "export to CSV")
  • I tried to export through the "modify and export" tab and it works

I have one thing in mind: How to completely remove preferences and history from asammdf. I saw that even changing the asammdf files from one folder to another and even redownloading new files, my former openned folders or dbc database are reminded. So I guess some preferences or history are remtained. Is there a mean to completely erase folder or registry used by asammdf ?

I am know quite stuck and would really appreciate your help. Using the Laptop B is only a temporary work around for me. I am able to make some tests for you if required.

regards

As a precision, I used up to now the download available on CSS doc website so without install

Right now, I just installed the latest version from python pip installs -I asammdf[gui]
Build information:
version 8.7.2
PySide6 6.10.0
CPython 3.13.7 x64

And I have the same problem using this on Laptop A

I can add some more information after investigation. I think I found the root cause on an user point of view. I don't have the knowledge to explain it on a programmer point of view:

When using the installed version described in my last comment, I noticed the following message while trying the export.

What is interesting to notice is that the file that is not found:

• is on a synchronised folder but has been deleted for several weeks
• is not requested either in the database manager nor the bus logging window

Another important point is that I uninstalled asammdf AND all the python tools and then reinstalled them and the problem is still here (asammdf tries to reach this file)

If I create again the path and the file, all is working well
If I remove the file the problem reappears
I tried to add several files in the "Bus Loggin" tab and in the "database manager", to quit and reopen asammdf, hoping it will make asammdf "forget" this file but it didn't work.

So, I have a workaround by only letting this folder and file.

I hope this can help you fix this bug for a next version.

Thanks for summarizing your findings.

@danielhrisca I wonder if the original driver of the initial issue could be related to the DBC having "spaces" in the file path name? And then this maybe being combined with the fact that it seems like this previous DBC is 'cached' in a way that is not possible for the end user to clear? Any suggestions are welcome.

Same problem here as well

with the latest development branch code you can reset the settings by starting the applciation with the following command

asammdf.exe --reset
