Convert arxml file to dbc file wrong

[MaggieLxj]

when i convert the arxml file, I found signals in the file, but no dbc file output. Maybe it's because the size of the arxml file is 9M? Please help me solve this problem, thank you.

└─[0] canconvert -vv 'H37_Project_SOMEIP_Service_Table_V7.0.1_TDA4_Acore-20231031023628.arxml' H37.dbc
INFO - convert - Importing H37_Project_SOMEIP_Service_Table_V7.0.1_TDA4_Acore-20231031023628.arxml ...

Then nothing happened.

Hi @MaggieLxj ,

first off all it seems you are converting a SOME/IP-ARXML to dbc which does not make much sense.

But - if you want to, you have to use either " --arxmlIgnoreClusterInfo" or "--arxmlEthernet" command line switch else the ethernet-part of arxml is ignored.

After that you should see at least the signals in the dbc.

Thank you for your answer. I've already get the signals I want by adding "--arxmlEthernet" command line switch.
The next question is how to get the dbc file in python script? Don't use the style of 'os.system(command line)', just use canmatrix API.
By the way, do you know how to use arxml file to decode pcap file by any python tools?

hi @MaggieLxj
canmatrix.formats.loadp() and friends should solve your issue

[MaggieLxj]

The converted dbc file has illegal segmentation description. So I couldn't use them.

Hi @MaggieLxj

what ist the "segmentation description" ?
Do you have some screenshot of the error?

[MaggieLxj]

Just pop-up window said that when I open the dbc file use canoe. No more information. Later I can take a screen shot and show you
