CAN Failing sporadically during overnight Testing

[Bhuvaneshwaran_K]

I am facing a sporadic issue when I run the CAN for overnight testing. 

I am using xQueueSendToBack interface to transmit CAN messages. 

The Can_pal1_instance configuration is as follows :

const can_user_config_t can_pal1_Config0 = {

    .txBuffNum = 16UL,

    .rxBuffNum = 16UL,

    .mode = CAN_NORMAL_MODE,

    .peClkSrc = CAN_CLK_SOURCE_OSC,

    .enableFD = false,

    .payloadSize = CAN_PAYLOAD_SIZE_8,

    .nominalBitrate = {

        .propSeg = 7,

        .phaseSeg1 = 4,

        .phaseSeg2 = 1,

        .preDivider = 4,

        .rJumpwidth = 1

    },

    .dataBitrate = {

        .propSeg = 7,

        .phaseSeg1 = 4,

        .phaseSeg2 = 1,

        .preDivider = 4,

        .rJumpwidth = 1

    },

    .extension = NULL,

};

The MCU used is MPC5746C. The SDK version used here is 3.0.3 

The below error message is showcased after a period of time 

Example : 

359.003277 1 Statistic: D 4 R 0 XD 0 XR 0 E 0 O 0 B 0.09%
359.003277 CAN 1 Status:chip status error active

Hi,

not sure of the log you posted. Is it something you created/send in your code?
If the error active status points to FlexCAN module Fault Confinement State ESR1[FLTCONF], then error active could not point to significant issue. FlexCAN is starting from error active state, it is kept until error counters are below 128. If you detect any error you should read ECR/ESR1 register to know a source of error and react accordingly.

The log is something which we get in Vector CANoe

Hi,

I do not know CANoe, so what does that say?
What is an issue on MCU side?

Hi,

could you please specify an MCU you have and S32DS and SDK version you are using?
What does "failing" mean in fact? Can you described behavior in more detail?

BR, Petr

[Bhuvaneshwaran_K]

MCU used is MPC5746C. 

S32 Version : S32 Design Studio for Power Architecture; Version: 2.1

SDK version : S32_SDK_S32PA_RTM_3.0.3.

The CAN transmission is not happening after a period of time, say 4 hours during overnight testing.

Hi,

does it mean you cannot prepare TX MB using Send function or this is possible, TX MB is prepared for transmission but module does not send the message out?
