LP-MSPM0G3507: I cant see nothing on CANTx pin with default example single_tx project

Tool/software:

Hi, 

I am using LP-MSPM0G3507 development kit. And i create a new example project name of mcan_single_message_tx_LP_MSPM0G3507_nortos_gss. 

This project doing basicly write a can message in every while loop. I did debug and i saw the code working on while loop so i think it should be send message.

After that, i decided to use osiloscope. I connected the PA12 MCAN0 Tx pin and i saw this;

I am also using SN65HVD230 canbus transceiver. And there is CANH meas;

This is my currently code i am using. I closed the FD mode. 

#include "ti_msp_dl_config.h"

int main(void)
{
    DL_MCAN_TxBufElement txMsg;

    SYSCFG_DL_init();

    txMsg.id  = ((uint32_t)(0x4)) << 18U;
    txMsg.rtr = 0U;
    txMsg.xtd = 0U;
    txMsg.esi = 0U;
    txMsg.dlc = 1U;
    txMsg.brs = 0U;
    txMsg.fdf = 0U;
    txMsg.efc = 1U;
    txMsg.mm  = 0xAAU;
    txMsg.data[0] = LED_STATUS_ON;

    while (DL_MCAN_OPERATION_MODE_NORMAL != DL_MCAN_getOpMode(MCAN0_INST));

    while (1) {
        DL_MCAN_writeMsgRam(MCAN0_INST, DL_MCAN_MEM_TYPE_BUF, 0U, &txMsg);
        DL_MCAN_TXBufAddReq(MCAN0_INST, 0U);

        for (volatile int i = 0; i < 100000; i++); // gecikme döngüsü
    }
}

If anyone could help I would be very happy. 

Best regards.
