arxml to dbc/csv has no output at all with python 3.8.3 (anaconda)

[daemonPainter]

I have an Anaconda install. Via the Anaconda Prompt I pip install the program just fine, I can run the help without issues. I have an arxml file (around 10MB) that I'd like to convert into a DBC or CSV file.

I run canconvert IN.arxml OUT.dbc, get the following input, but no dbc file is created. When provided an empty dbc file, nothing changes.

INFO - convert - Importing IN.arxml ...
INFO - convert - done

INFO - convert - Exporting OUT.dbc
INFO - convert - done

Am I doing something wrong?

Hi @daemonPainter

Well, what you do looks good.
Do you have CAN-Clusters in your ARXML?

Could you also try canconvert -vv IN.arxml OUT.arxml ?

I guess you can't provide your ARXML anyhow?

[daemonPainter]

Hi @ebroecker , thanks for the quick response!

Yeah, the arxml itself can't be shared for IP reasons 😢
I've tried that and got this:

DEBUG - arxml - Read arxml ...
DEBUG - arxml -  Done

DEBUG - arxml - Build arTree ...
DEBUG - arxml -  Done

DEBUG - arxml - 0 frames in arxml...
DEBUG - arxml - 0 can-frame-triggering in arxml...
DEBUG - arxml - 0 SIGNAL-TO-PDU-MAPPINGS in arxml...
DEBUG - arxml - 1057 I-SIGNAL-TO-I-PDU-MAPPING in arxml...
INFO - convert - done

dunno if it helps, it should be mostly ethernet communication going on in this ECU. How can I check for CAN-Clusters?

EDIT: I suppose the output should be in the same folder I'm calling the script from, right? I cd'd into the arxml folder, and I'm calling there the script.

EDIT 2: I have a strange feeling that I might be misusing the tool: from the docs I got the impression that I can get arxml to dbc conversion regardless of the bus type (CAN / ETH), but I fear this might not be the case?

[ebroecker]

Well yes. Canmatrix ist CAN only, nur you can try sameip branch.
There ist some more Bus Support...
