UDS on LIN #49

Open Abor88 opened 6 months ago

Abor88 commented 6 months ago

Hello, Is UDS on LIN supported? I tried sending UDS Default session and I see that Master Request is properly sent with ID = 60 (0x3C) but then I see Slave Response header sent with ID = 125 (0x7D) which is the PID and not the ID of Slave Response frame (I am expecting a frame sent with ID = 61 (0x3D)). So in my case I see a timeout in Slave response but I have verified with CANoe that my slave is working in Slave response.

Please setup correct NAD， Over LIN is support, EcuBus as LIN master, will send 0x3c+ data, and 0x3d (header only)

Abor88 commented 6 months ago

Thank you for you response and your support. My slave is responding on NAD = 6 so in ECU BUS tool I setup NAD with Send NAD = 6 Receive NAD = 0 (since it is not supported to set Send NAD = Receive NAD). STmin and P2 set as default. Am I missing something?

make CAN-OE work as diagnostic only mode.

Abor88 commented 6 months ago

I have tested my slave with CANoe separately. Now in my setup I have only ECU BUS connected with a Peak PLIN device. No other tools are opened.

frankie-zeng commented 6 months ago

sorry, I mean, you sould config CAN-OE LIN LDF schedule config as diagnostic only mode

Abor88 commented 6 months ago

Sorry, maybe I am not properly understanding. I am using only ECU BUS now and no LDF is loaded. I just opened the tool, configured Response NAD, create 1 UDS project and try to send default session. What is missing in my setup?

No ok, I can use CANoe. The question is why should I use CANoe since I am using ECU Bus only? Is it no possible to use only ECU BUS?

try to capture the raw log from PLIN-View, image

frankie-zeng commented 6 months ago

you slave doesn't response, check your slave code.

Abor88 commented 6 months ago

I can send also the screen of ECU BUS log in debug image

The point is this: it seems that the slave is not responding but if I detach it from ECU Bus and on another PC I use CANoe, the slave is always responding

frankie-zeng commented 6 months ago

anyway, you need check it in your slave side, why the slave doesn't response...,
