Waring occurs every time using PCAN-UDS to send request

Francredy · Post by **Francredy** » Tue 19. Nov 2019, 02:32

Hello together,

I'm using PCAN-UDS to test the ECU UDS stack, but sometimes ECU does not response when request with multiple frame, like 2E F1 90 XX .. XX; then the trace was checked, it is found Waring occurs every time using PCAN-UDS to send request, no matter request with single frame or multiple frame, how can i solve this issue?

I'm looking forward for your help

following is the trace:

Hello,

Those error-messages indicate that there seems to be an issue with the CAN bus itself.

Please make sure your CAN bus is properly terminated and that you use the correct configuration to communicate with your ECU.

Best Regards

Marvin

thank you for your reply

Here is my code , Could you help me check it?

Code: Select all

	UDS_Channel = PUDS_USBBUS1;

	// Initializing of the UDS Communication session 
    UDS_Initialize(UDS_Channel, PUDS_BAUD_500K, PCAN_TYPE_ISA, 0x0100, 3);

	// Define Address
	UDS_iBuffer = 0x01;
	UDS_SetValue(UDS_Channel, PUDS_PARAM_SERVER_ADDRESS, &UDS_iBuffer, 1);

	UDS_ulBuffer = 2000;
	UDS_SetValue(UDS_Channel, PUDS_PARAM_TIMEOUT_REQUEST, &UDS_ulBuffer, sizeof(UDS_ulBuffer));
	UDS_SetValue(UDS_Channel, PUDS_PARAM_TIMEOUT_RESPONSE, &UDS_ulBuffer, sizeof(UDS_ulBuffer));

    // Note: Channel is properly initialized with UDS_Initialize(..)

    UDS_SetValue(UDS_Channel,PUDS_PARAM_MAPPING_ADD,&UDS_Message,sizeof(UDS_Message));

Hello,

As Marvin said, the errors are triggered due to a physical problem (wrong bit rate, wrong electrical resistance a.k.a. termination, etc).
You are trying to define already existing mappings, without removing them. Mappings with Source 0xF1 (test equipment) and ECU1 (0x01) are already configured in UDS. See help file chapter 4.3
You are changing the default node address for "test equipment" (your application) to 0x1,
Francredy wrote: // Define Address
UDS_iBuffer = 0x01;
UDS_SetValue(UDS_Channel, PUDS_PARAM_SERVER_ADDRESS, &UDS_iBuffer, 1);
and later down you still use "0xF1"
Francredy wrote: // Note: Channel is properly initialized with UDS_Initialize(..)
UDS_Message.NETADDRINFO.SA=0xF1;
UDS_Message.NETADDRINFO.TA=0x01;

Please be sure you are using the right termination of 120 ohm, and that the bitrate being used by your ECU is the same as in your application.

Please read the mentioned chapter, 4.3. "UDS and ISO-TP Network Addressing Information". Here you will find information about already defined Mappings, how to configure the API in a non-standard context, for example, removing/changing standard mappings, changing the SA (source address), and even an example demonstrating this (chapter 4.3.3, page 343).

By the way, the initialization of the channel

Francredy wrote: // Initializing of the UDS Communication session
UDS_Channel = PUDS_USBBUS1;
UDS_Initialize(UDS_Channel, PUDS_BAUD_500K, PCAN_TYPE_ISA, 0x0100, 3);

the last 3 parameters are only needed when using non plug&play hardware. Since you are using an USB adapter, you just need to call this function with the channel number and the desired bit rate, like this

Code: Select all

UDS_Initialize(UDS_Channel, PUDS_BAUD_500K);
