AM2432: icssg enet_lwip example for Profinet communication

Hi

The ticket is assigned to expert.

Please expect some delay in response as expert is out of office.

Hi Jie,

I have started looking into the issue. Let me get back by Friday on this.

Thank you. Is there any solution?

Hi  jie ming

1. The forwarding rules are programmed using FDB table. The forwarding and tagging information has to set using an IOCTL. ICSSG_PER_IOCTL_VLAN_SET_ENTRY is the IOCTL used to set an entry. Use this ENET_IOCTL() API and pass ICSSG_PER_IOCTL_VLAN_SET_ENTRY command with valid params.
2. I assume you are trying switch mode. Do you want to know the receive frame port number?
3. You can send it as an directed packet with specifying the port number (this will push packets to ring buffers of specified port).

Hi,

1. Would you please show me an example?

2. Yes, ICSSG in switch mode. I want to  know the receive frame port number from LWIP interface.

3. Would you please show me an example?

Hi  jie ming 

1. please refer to https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/EXAMPLES_ENET_VLAN_ICSSG.html

2. I am not sure if LwiP provides any such APIs, I will have to check it, mean while it will be helpful if you can also check on your end on lwip forums.

) Specify egress port via netif->linkoutput

If I want to send a LLDP multicast package to port 1, how to achieve this?

This can be again done using VLAN tagging using FDB. Please refer same example as mentioned above.

Hi,

Thank you for the support! I add FDB as following code:

int32_t add_mac_fdb_entry()
{
    uint32_t instId;
    int32_t retVal = RET_FAILURE;
    Enet_Type enetType;
    bool semStatus;
    Enet_IoctlPrms prms;
    Icssg_FdbEntry params;
    SemaphoreP_Object ayncIoctlSemObj;
    int32_t status = ENET_SOK;
    EnetApp_HandleInfo handleInfo;
    uint32_t coreId = EnetSoc_getCoreId();
    EnetApp_getEnetInstInfo(&enetType, &instId);
    EnetApp_acquireHandleInfo(enetType, instId, &handleInfo);
    if(ENET_ICSSG_SWITCH != enetType) return retVal;

    status = SemaphoreP_constructBinary(&ayncIoctlSemObj, 0);
    DebugP_assert(SystemP_SUCCESS == status);

    Enet_registerEventCb(handleInfo.hEnet,
                        ENET_EVT_ASYNC_CMD_RESP,
                        0U,
                        asyncIoctlCb,
                        (void *)&ayncIoctlSemObj);
    int i = 0;
    //Now make an entry in FDB for the HOST MAC address using Asynchronous IOCTL
    for (i = 0; i < ENET_MAC_ADDR_LEN; i++)
    {
        params.macAddr[i] = lldp_mac[i];
    }
    params.vlanId = 0;
    params.fdbEntry[0] = ICSSG_FDB_ENTRY_P0_MEMBERSHIP|ICSSG_FDB_ENTRY_VALID;
    params.fdbEntry[1] = ICSSG_FDB_ENTRY_P0_MEMBERSHIP|ICSSG_FDB_ENTRY_VALID;

    EnetAppUtils_print("LLDP entry in FDB \n\r");

    ENET_IOCTL_SET_IN_ARGS(&prms, &params);
    ENET_IOCTL(handleInfo.hEnet, coreId, ICSSG_FDB_IOCTL_ADD_ENTRY, &prms, retVal);
    if (retVal == ENET_SINPROGRESS)
    {
        EnetAppUtils_print("Success: IOCTL command sent for making MAC entry in FDB \n\r");
        /* Wait for asyc ioctl to complete */
        do
        {
            Enet_poll(handleInfo.hEnet, ENET_EVT_ASYNC_CMD_RESP, NULL, 0U);
            semStatus = SemaphoreP_pend(&ayncIoctlSemObj, SystemP_WAIT_FOREVER);
        } while (semStatus != SystemP_SUCCESS);

        retVal = ENET_SOK;
    }
    else
    {
        EnetAppUtils_print("ERROR: IOCTL command sent for making MAC entry in FDB failed\n\r");
    }

    EnetAppUtils_print("DCP entry in FDB \n\r");
    for (i = 0; i < ENET_MAC_ADDR_LEN; i++)
    {
        params.macAddr[i] = dcp_mac[i];
    }
    params.vlanId = 0;
    params.fdbEntry[0] = ICSSG_FDB_ENTRY_P0_MEMBERSHIP|ICSSG_FDB_ENTRY_P1_MEMBERSHIP|ICSSG_FDB_ENTRY_P2_MEMBERSHIP|ICSSG_FDB_ENTRY_VALID;
    params.fdbEntry[1] = ICSSG_FDB_ENTRY_P0_MEMBERSHIP|ICSSG_FDB_ENTRY_P1_MEMBERSHIP|ICSSG_FDB_ENTRY_P2_MEMBERSHIP|ICSSG_FDB_ENTRY_VALID;

    ENET_IOCTL_SET_IN_ARGS(&prms, &params);
    ENET_IOCTL(handleInfo.hEnet, coreId, ICSSG_FDB_IOCTL_ADD_ENTRY, &prms, retVal);
    if (retVal == ENET_SINPROGRESS)
    {
        EnetAppUtils_print("Success: IOCTL command sent for making MAC entry in FDB \n\r");
        /* Wait for asyc ioctl to complete */
        do
        {
            Enet_poll(handleInfo.hEnet, ENET_EVT_ASYNC_CMD_RESP, NULL, 0U);
            semStatus = SemaphoreP_pend(&ayncIoctlSemObj, SystemP_WAIT_FOREVER);
        } while (semStatus != SystemP_SUCCESS);

        retVal = ENET_SOK;
    }
    else
    {
        EnetAppUtils_print("ERROR: IOCTL command sent for making MAC entry in FDB failed\n\r");
    }

    SemaphoreP_destruct(&ayncIoctlSemObj);
    Enet_unregisterEventCb(handleInfo.hEnet, ENET_EVT_ASYNC_CMD_RESP, 0U);
    return retVal;
}

and add call back to handle multicast packet:

err_t eth_unknow_type_hook(struct pbuf *pbuf, struct netif *netif)
{
    uint8_t portNum = 2;
    if(pbuf->flags != 0) portNum = 1;
    uint8_t* data = (uint8_t*) pbuf->payload;
    uint8_t type = getMcType(data);
    printf("P%02X", portNum);
    switch(type)
    {
    case MC_LLDP: printf(" LLDP ");break;
    case MC_DCP: printf(" DCP ");break;
    default: printf(" UNKNOWN ");break;
    }
    printf("%02X%02X%02X%02X%02X%02X\r\n",
           data[6], data[7], data[8],data[9], data[10], data[11]);
    return ERR_OK;
}

At beginning the code works OK. After host port cecieve a mount of multicast packets, it stop recieve any multicast from two ports.

Would you please help me solve this problem?

With best regards

Hi,

Can you please tell me if cpu load is still getting printed or not. If not then example might have crashed.

CPU load is still printed as normal. Seems like the fdb entry for Mcast was automatically removed after ~20-30 packets recieved.  

Hi Jie,

We will try to reproduce the issue on our end and come back on it by early next week.
