Signals not able to find using MDF object by loading the MF4 file #1012

Hi Daniel,

I need your help to solve my issue when loading MF4 files using asammdf.

I have an MF4 file that contains a large number of CAN-FD signals. I am able to read all the signals using CANoe, but when I try to use asammdf to read the file, I find that there are very few signals in the groups. Many signals not able to find in the groups or channels. Could you please provide some guidance on what I should do next? Thank you very much.

BR,

Without the file I can only suspect that it contains bus logging data that is not supported (FlexRay, MOST, Eth ...)

Hi Daniel,

Thank you very much for your prompt response. As you know, it is difficult for me to share internal MF4 files. My MF4 file only contains CAN-FD signals and does not include data recorded from other bus systems like FlexRay, MOST, Ethernet, etc.

I have sent you an email. I've included excerpts from the groups information read from the current MF4 file and sent it to your email. Please check if it's useful. There are some groups' information that I'm indeed not sure if they contain signals that I cannot read.

Also, I have another idea. Should we also use the ARXML file to read the signal content?

For me, this is indeed a challenge.

Thanks again.
