Problem in receiving multiple frames

pankajprasad100 — Tue, 08 Mar 2022 07:18:16 GMT

I am working on LIN diagnostics in which I have used ld_receive_message and got the data which is of single frame.

But when I sent the MULTIPLE FRAMES for SID-0x34 then I can see the data on the LIN bus but the receiving buffer is not updated.

While debugging I got to know data is coming in the descriptor but due to LD_NO_DATA in rx_msg_status the buffers are not updating.

Any suggestions to receive the data would be highly appreciated.

Hello,

After received diagnostic request, the slave node responded with a negative response. That mean the slave dose not support this request(SID=0x34) and the data will be not updated in data buffer. So, please recheck the configuration to make sure that the SID has been supported.

Regarding using the UDS service, I have an example to implement the UDS frame base on SDK LIN stack release 4.0.2. Hope it can help to you.

On S32DS:

On S32DS:

Tick on Use Transport Layer and Support Diagnostic Service.
Choose diagnostic class 3
Set the max message length corresponding.
Tick to use and configured UDS

The configuration files is generated

lin_cfg.c

Lin_cfg.h

Best Regards,

Nam
