Support for ECUC ARXMLs

[andraflandra]

Hi, I am using an internal .arxml file I cannot show you but also a public one available here:
https://raw.githubusercontent.com/nikidimitrow/Learning-AUTOSAR-fundamental/master/BasicsOfAUTOSAR/MyECU.ecuc.arxml

I get this readout in cmd (win10):
`
C:\Python27\Scripts>canconvert -vv D:\user\ECUexample.arxml D:\user\ECUexampleAAA.xlsx
INFO - convert - Importing D:\user\ECUexample.arxml ...
DEBUG - arxml - Read arxml ...
DEBUG - arxml - Done

Hi @andraflandra
this is an ECUC-ARXML.

Conversion will only work with an SYSTEM-DESCRIPTION-ARXML

[andraflandra]

How might I get this to work with ECUC-ARXML? Could your code be modified slightly or is a completely new solution needed?

edit:

Also, I found a System-ARXML file online and when trying to convert to .xlsx I get this:
DEBUG - arxml - Read arxml ...
DEBUG - arxml - Done

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

DEBUG - arxml - DEBUG 0 frames in arxml...
DEBUG - arxml - DEBUG 0 can-frame-triggering in arxml...
DEBUG - arxml - DEBUG 0 SIGNAL-TO-PDU-MAPPINGS in arxml...
DEBUG - arxml - DEBUG 12 I-SIGNAL-TO-I-PDU-MAPPING in arxml...

And when trying to compare two .arxml files this happens:
Traceback (most recent call last):
File "c:\python27\lib\runpy.py", line 174, in _run_module_as_main
"main", fname, loader, pkg_name)
File "c:\python27\lib\runpy.py", line 72, in run_code

File "c:\python27\lib\site-packages\canmatrix\compare.py", line 549, in main
db1 = next(iter(canmatrix.formats.loadp(matrix1).values()))
StopIteration

please try branch

pip install git+https://github.com/ebroecker/canmatrix@iss281#egg=canmatrix

[andraflandra]

First of all, thank you very much for your effort!

I can now convert the files but from the 1.329KB file all I get is a 6KB .xlsx table with only the first line of data as far as I can tell.

This is the readout in cmd:
INFO - arxml - seems to be a ECUC arxml. Very limited support for extracting canmatrix.
DEBUG - xls - DEBUG: Length of db.frames is 2

(this is the .arxml file I linked in the issue converted to .xlsx)
ECUexampleCONVERTED.xlsx

Also, the actual, non-example .arxml files I need to convert are still getting the line of "DEBUG 0 frames".
If there is any more info I can give you to make this work please let me know!,

edit: I also get this when trying to compare .arxml files:
Traceback (most recent call last):

Thanks again.

@andraflandra
what is the output of
canconvert -vv your_non_example.arxml some_test.dbc

Is there actual a Can-Bus defined in the ARXML?

[andraflandra]

This is the output of said command in cmd:

C:\Users\user1>canconvert -vv D:\file.arxml D:\some_test.dbc
INFO - convert - Importing D:\file.arxml ...
DEBUG - arxml - Read arxml ...
DEBUG - arxml -  Done

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

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

INFO - convert - Exporting D:\some_test.dbc ...
INFO - convert - done

However, this does not actually output/create any .dbc file.
(but doing the line on the example code gets me the same 2 frame file but in .dbc)

As for your question, these are the opening lines of the file:

REDACTED

Hi @andraflandra ,

Thanks.
what kind of ARXML is this? In what context did you get this file?

The debug output looks like there is no CAN communication defined in this ARXML:

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

[andraflandra]

It's from a model input, basically a database of host architecture for automotive. I do have a separate .dbc file that has CAN signals database on them.

I'm new to this so please excuse my ignorance.

[ebroecker]

If the ARXMLs describe a SWC (Software component) it will mostely certain not be any CAN information in it.

[andraflandra]

There are SWC components included so I would assume you are correct. Does this make it impossible to use canmatrix to port my kind of arxml to xlsx or can it be enhanced perhaps?

[ebroecker]

Sorry - this is a really complete other use case.
Something like extracting sender/receiver ports or/and exporting client/server ports from SWC-ARXML is a complete other work than exporting CAN communication information

[andraflandra]

Thank you for all the help in any case. I will try to find a different solution or build my own.
