Hi @namnguyenviet ,
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
