IWR1642: IWR1642的CANFD 可以注册几个接收CAN ID?

你好，我使用IWR1642的CAN FD发现，当我只注册了4个及以下的接收CAN ID时，程序可以运行。但我注册了第五个CAN ID后程序就不能执行了~~

注册CAN ID的代码如下，麻烦帮看看有什么问题~~

CANFD_MsgObjHandle          rxMsgObjHandle[5];

/* Setup the receive message object */
{
CANFD_MCANMsgObjCfgParams rxMsgObjectParams;
int32_t errCode = 0;
rxMsgObjectParams.direction = CANFD_Direction_RX;
rxMsgObjectParams.msgIdType = CANFD_MCANXidType_11_BIT;
rxMsgObjectParams.msgIdentifier = 0x100;
rxMsgObjHandle[0] = CANFD_createMsgObject (canHandle, &rxMsgObjectParams, &errCode);
if (rxMsgObjHandle[0] == NULL)
{
System_printf ("Error: CANFD create Rx message object failed [Error code %d]\n", errCode);
return -1;
}
}
{
CANFD_MCANMsgObjCfgParams rxMsgObjectParams;
int32_t errCode = 0;
rxMsgObjectParams.direction = CANFD_Direction_RX;
rxMsgObjectParams.msgIdType = CANFD_MCANXidType_11_BIT;
rxMsgObjectParams.msgIdentifier = 0x200;
rxMsgObjHandle[1] = CANFD_createMsgObject (canHandle, &rxMsgObjectParams, &errCode);
if (rxMsgObjHandle[1] == NULL)
{
System_printf ("Error: CANFD create Rx message object failed [Error code %d]\n", errCode);
return -1;
}
}
{
CANFD_MCANMsgObjCfgParams rxMsgObjectParams;
int32_t errCode = 0;
rxMsgObjectParams.direction = CANFD_Direction_RX;
rxMsgObjectParams.msgIdType = CANFD_MCANXidType_11_BIT;
rxMsgObjectParams.msgIdentifier = 0x300;
rxMsgObjHandle[2] = CANFD_createMsgObject (canHandle, &rxMsgObjectParams, &errCode);
if (rxMsgObjHandle[2] == NULL)
{
System_printf ("Error: CANFD create Rx message object failed [Error code %d]\n", errCode);
return -1;
}
}
{
CANFD_MCANMsgObjCfgParams rxMsgObjectParams;
int32_t errCode = 0;
rxMsgObjectParams.direction = CANFD_Direction_RX;
rxMsgObjectParams.msgIdType = CANFD_MCANXidType_11_BIT;
rxMsgObjectParams.msgIdentifier = 0x400;
rxMsgObjHandle[3] = CANFD_createMsgObject (canHandle, &rxMsgObjectParams, &errCode);
if (rxMsgObjHandle[3] == NULL)
{
System_printf ("Error: CANFD create Rx message object failed [Error code %d]\n", errCode);
return -1;
}
}
// {
