Aurix 2G MCMCAN can_write Bus off

[User22029]

Hello Support,

I'm using TriBoard TC397 V2.0 and MC-ISAR_AS422_TC3xx_BASIC_1.40.0
Follow the demo code for MCMCAN module, I write the code blew.

initial(){
    const Port_ConfigType * ConfigPtr = NULL_PTR;
    ConfigPtr = &Port_Config;
    Port_Init(ConfigPtr);
    IrqCan_Init();
    Can_17_McmCan_Init(&Can_17_McmCan_Config);
    Can_17_McmCan_SetControllerMode (Can_17_McmCanConf_CanController_CanController_0, CAN_T_START);
    Can_17_McmCan_SetControllerMode (Can_17_McmCanConf_CanController_CanController_1, CAN_T_START);
}

main()
{
    initial();
    while(1){

    Can_17_McmCan_Write(2, &PduInfo_1[0]) ;
    /* Delay */
    Counter = 0x5FFFF;
    while(Counter--)
    {}
    }
}

Here is my EB tresos config


Initial OK, but when run after Can_17_McmCan_Write -> Can_17_McmCan_lWriteMsgObj
code line 5840

NodeRegAddressPtr->TX.BAR.U = (Ifx_UReg_32Bit)BuffIndex;

It will occur bus off error, and then into bus off ISR



I cannot see any message in busmaster
And in next while loop it will always stuck at bus off.

It should be no problem after Can_write function execute,right?
Please give me some suggestion to solve this problem, thank you.

Best regards

Hi,

I am facing the same bus off while using two can nodes.

"INIT" and Busoff coming once the can transmit is called.

Is the issue resolved ?
could you support me for this ?
