Hello,
When I configured as standart ID's, I received CAN messages.
But When I set CAN ID as extended, I do not received CAN messages.
Do I miss a any configuration that I need?
Here is CAN2_init function:
void CAN2_Init(void)
{
GPIO_PinInit(GPIO10, 1U, &pinConfig); // CAN2 STANDBY PIN INIT
GPIO_PinInit(GPIO4, 6U, &pinConfig); // CAN2 ENABLE PIN INIT
GPIO_PinWrite(GPIO10, 1U, 1U); // CAN2 STANDBY HIGH
GPIO_PinWrite(GPIO4, 6U, 1U); // CAN2 ENABLE HIGH
flexcan_config_t flexcanConfig;
flexcan_rx_mb_config_t mbConfig;
flexcan_rx_mb_config_t mbConfig1;
flexcan_rx_mb_config_t mbConfig2;
flexcan_rx_mb_config_t mbConfig3;
clock_root_config_t rootCfg = {0};
rootCfg.mux = FLEXCAN_CLOCK_SOURCE_SELECT;
rootCfg.div = FLEXCAN_CLOCK_SOURCE_DIVIDER;
CLOCK_SetRootClock(kCLOCK_Root_Can2, &rootCfg);
FLEXCAN_GetDefaultConfig(&flexcanConfig);
flexcan_timing_config_t timing_config;
memset(&timing_config, 0, sizeof(flexcan_timing_config_t));
if (FLEXCAN_CalculateImprovedTimingValues(CAN2, flexcanConfig.bitRate, EXAMPLE_CAN_CLK_FREQ, &timing_config))
{
/* Update the improved timing configuration*/
memcpy(&(flexcanConfig.timingConfig), &timing_config, sizeof(flexcan_timing_config_t));
}
else
{
// LOG_INFO("No found Improved Timing Configuration. Just used default configuration\r\n\r\n");
}
FLEXCAN_Init(CAN2, &flexcanConfig, EXAMPLE_CAN_CLK_FREQ);
/* Create FlexCAN handle structure and set call back function. */
FLEXCAN_TransferCreateHandle(CAN2, &flexcanHandle, flexcan_callback, NULL);
/* Set Rx Masking mechanism. */
FLEXCAN_SetRxMbGlobalMask(CAN2, FLEXCAN_RX_MB_EXT_MASK(0x1FFFFFFF, 0, 0)); //0x18DAFFF9 0x625
/* Setup Rx Message Buffer. */
mbConfig3.format = kFLEXCAN_FrameFormatExtend;
mbConfig3.type = kFLEXCAN_FrameTypeData;
mbConfig3.id = FLEXCAN_ID_EXT(0x18DAFFF9);
FLEXCAN_SetRxMbConfig(CAN2, RX_MESSAGE_BUFFER_NUM3, &mbConfig3, true);
/* Setup Tx Message Buffer. */
FLEXCAN_SetTxMbConfig(CAN2, TX_MESSAGE_BUFFER_NUM3, true);
/* Start receive data through Rx Message Buffer. */
rxXfer.mbIdx = (uint8_t)RX_MESSAGE_BUFFER_NUM;
rxXfer.frame = &rxFrame1;
(void)FLEXCAN_TransferReceiveNonBlocking(CAN2, &flexcanHandle, &rxXfer);
rxXfer1.mbIdx = (uint8_t)RX_MESSAGE_BUFFER_NUM1;

(void)FLEXCAN_TransferReceiveNonBlocking(CAN2, &flexcanHandle, &rxXfer2);
rxXfer3.mbIdx = (uint8_t)RX_MESSAGE_BUFFER_NUM3;
rxXfer3.frame = &rxFrame4;
(void)FLEXCAN_TransferReceiveNonBlocking(CAN2, &flexcanHandle, &rxXfer3);
CAN2_BSI4_frame.length = (8U);
CAN2_BSI4_frame.format = kFLEXCAN_FrameFormatExtend;
CAN2_BSI4_frame.type = kFLEXCAN_FrameTypeData;
/* Start receive data through Tx Message Buffer. */
