AM2732: How to configure the code to receive the non-zero priority VLAN message?

Shine
Genius 13655 points
Part Number: AM2732

Hello Champs,

SW: mcu_plus_sdk_am273x_08_01_00_34

Customer ran C:\ti\mcu_plus_sdk_am273x_08_03_00_18\examples\networking\enet_loopback example, he can receive the message of VLAN with priority=0. But he can't receive the message of VLAN with non-zero priority. 

How to configure the code to receive the non-zero priority VLAN message?

Thanks
Rgds

    Hi Shine,

    For receiving the non-zero priority VLAN, you need to add a policer entry with required priority using CPSW_ALE_IOCTL_SET_POLICER  IOCTL.

    AM273x MCU+ SDK: Enet LLD IOCTL interface (ti.com)

    AM273x MCU+ SDK: CpswAle_PolicerMatchParams Struct Reference (ti.com)

    AM273x MCU+ SDK: CPSW Address Lookup Engine (ALE) (ti.com)

    For using the Enet IOCTLs, you can refer to existing examples in mcu_plus_sdk_am273x_08_03_00_18\examples\networking.

    Regards,

    Prasad

    Hello Shine,

    Please ignore my previous response. I assumed you made changed to loopback code to enable specific priority handling.

    Regarding your issue, can you please share how you send non-zero priority messages? Did you modify loopback example to create new VLAN packets?

    Can you please share log and CPSW statistics (you can print stats using below)?

    Hi Nilabh,

    Thanks for your great support. 

    Update some information. 

    Customer found that ALE_STATUS is always zero which may cause the POLICER match issue. 

    How to make POLCNTDIV8 is non zero?

    Hi Shine,

    To debug this issue further I would need the below info here. As the example by default does not uses sample vlan packets and its configured for vlan unaware mode. And the example is configured for 0 vlan id UNICAST packets reception.

    Prasad Jondhale said:
    Regarding your issue, can you please share how you send non-zero priority messages? Did you modify loopback example to create new VLAN packets?

    For speeding up debug process, Can you please share example project(modified for vlan handling) by customer.

    Customer defined the structures for the protocol header including the vlan, then added these structures to ethernet buf, and used send() API to send it.

    Hi Nilabh,

    Thanks for your help.

    Sorry that customer's     project is under NDA, so he can't send his code. He suggested us to do below test: configure the lwip demo, use xcap to send vlan priority-4 message to the board, then the board receive the message and send to PC.

    Hi Shine,

    For VLAN Support in LWIP example following changes are to be made for enabling vlan id 4U packets:

    1. Enable macro 

    #define ETHARP_SUPPORT_VLAN             1

    in file mcu_plus_sdk\source\networking\lwip\lwip-stack\src\include\lwip\opt.h

    2. In the same above file add below two lines:

    +#define ETHARP_VLAN_CHECK 4

     +#define LWIP_HOOK_VLAN_SET(netif, p, src, dst, eth_type) (4U)

    3. Rebuild lwip stack and lwip contrib and enet_cpsw libraries.

    4. Rebuild the example and run.

    Let me know if this works for you.

    BR

    Hi Nilabh,

    Thanks for your help.

    Customer configured his code as you mentioned. Below is his configuration.

    #define ETHARP_SUPPORT_VLAN 1
    #define VLAN_VID 104
    #define VLAN_PRI 4
    #define VLAN_CFI 0
    #define LWIP_HOOK_VLAN_SET(netif, p, src, dst, eth_type) ((VLAN_PRI << 13) | (VLAN_CFI << 12) | VLAN_VID)

    He wanted to receive Priority 4 VLAN message instead of VLAN ID 4 message. There is no problem with the configuration of LWIP. 

    BTW, he migrated to the newest SDK, he still failed. 

    He wanted to know to change the VLAN priority by using Policer. He failed because reading the ALE_STATUS register is 0. 

    Thanks.

    Hi Shine,

    Please refer below:

    1. Please follow example: mcu_plus_sdk\examples\networking\enet_layer2_multi_channel example to setup ALE and vlan priority filtering.

    2.Use below code as a sample to configure the ALE:

     

    void EnetApp_setCpswPolicer(EnetApp_PerCtxt *perCtxt)
{
    int32_t status;
    Enet_IoctlPrms prms;
    CpswAle_SetPolicerEntryOutArgs setPolicerOutArgs;
    CpswAle_SetPolicerEntryInArgs setPolicerInArgs;

    /* Set the Policer configuration */
    memset(&setPolicerInArgs, 0, sizeof(setPolicerInArgs));
    setPolicerInArgs.policerMatch.policerMatchEnMask = CPSW_ALE_POLICER_MATCH_MACSRC |
                                                       CPSW_ALE_POLICER_MATCH_ETHERTYPE |
                                                       CPSW_ALE_POLICER_MATCH_PORT | 
                                                       CPSW_ALE_POLICER_MATCH_PRIORITY;
    setPolicerInArgs.policerMatch.etherType = 0x8100;
    setPolicerInArgs.policerMatch.priority = 4U;
    setPolicerInArgs.policerMatch.portNum = CPSW_ALE_MACPORT_TO_ALEPORT(ENET_TEST_POLICER_INGRESS_PORT);
    memcpy(&setPolicerInArgs.policerMatch.srcMacAddrInfo.addr.addr[0U], testSrcAddr, sizeof(setPolicerInArgs.policerMatch.srcMacAddrInfo.addr.addr));
    setPolicerInArgs.policerMatch.srcMacAddrInfo.addr.vlanId = 0;
    setPolicerInArgs.policerMatch.srcMacAddrInfo.portNum = CPSW_ALE_MACPORT_TO_ALEPORT(ENET_TEST_POLICER_INGRESS_PORT);

    ENET_IOCTL_SET_INOUT_ARGS(&prms, &setPolicerInArgs, &setPolicerOutArgs);
    ENET_IOCTL(perCtxt->hEnet, gEnetApp.coreId, CPSW_ALE_IOCTL_SET_POLICER, &prms, status);
    if (status != ENET_SOK)
    {
        EnetAppUtils_print("\nEnetApp_setCpswPolicer() failed CPSW_ALE_IOCTL_SET_POLICER: %d\n", status);
    }
    else
    {
        EnetAppUtils_print("\nRate limiting Enabled port %d on Src MAC " , CPSW_ALE_MACPORT_TO_ALEPORT(ENET_TEST_POLICER_INGRESS_PORT));
        EnetAppUtils_printMacAddr(testSrcAddr);
    }
}

    3. Rebuild the example.

    Please let me know if you need any help with this.

    Thanks four help and give us the refer link,  our test can recv pri=1 ptp message in ptp recv task.

    Our project cancel the vlan use.

    No,  we still can't recv the  priority=4 echo packets in the echo recv task, but the host stat tx packets num is increasing.

    Hi Jeff,

    The am273 device does not have the channel over ride feature, i.e. The dma channel ID1 can support only priority 1 packets. You cannot override it to allow priority4 packets. If you want to use vlan priority 4 you need to create a channel with channel ID 4. 

    You can see that PTP channel has channel ID as 1 i.e why it is able to receive priority 1 packets.

    Jeff,

    In 8.4 SDK, Go to syscfg and add DMA channels as below, make sure you pass the channel4 parameters in open dma function in mcu_plus_sdk\examples\networking\enet_layer2_multi_channel\V1\multi_channel_dataflow.c.
