66AK2H14: 5-port gigabit Ethernet switch problem

Hi Fabio,

Is the ARM application running on Linux? Are you working on top of PLSDK release? Can you please provide some insight on this? 

If you are looking for RTOS side, have you installed the Processor SDK RTOS and you can refer to NDK examples. You may be needed to tweak the NIMU code as this is your custom board, if you are working on RTOS.

So, please let us know if you are working on Linux or RTOS?

Thanks.

Hi Aravind,

The application is running on RTOS, pdk_k2hk_4_0_10, ndk_2_26_00_08, my code is based on  NIMU_emacExample_EVMK2H_armBiosExampleProject 

Should I modify  nimu_eth.c? 

Thanks

Fabio

Hi Fabio,

Thanks for providing the details.

Yes, you need to modify nimu_eth.c, which is currently setting one port.

There may be some more tweaks needed for you, but as a starting point, you can update below for nimu_eth.c

1. Init_cpsw() to initialize the SGMII for all of the eth ports
2. Init_Mac() for all the port numbers

Please note that I would be on vacation starting tomorrow and would be back on Jan 4th. So, please expect the response delayed for your next questions.

Happy holidays!

Thanks 

Hi

I've done the following modification to nimu_eth.c

- inside CSL_SgmiiDefSerdesSetup, change serdes_lane_enable_params.num_lanes = 2 ---> serdes_lane_enable_params.num_lanes = 4
- modify Init_SGMII and call for all 4 ports:

Init_SGMII(0);
Init_SGMII(1);
Init_SGMII(2);
Init_SGMII(3);

This is my Init_SGMII

void Init_SGMII (uint32_t macPortNum)
{
    CSL_SGMII_ADVABILITY    sgmiiCfg;
    CSL_SGMII_STATUS        sgmiiStatus;
    unsigned int timeout = 1000;

    /* Reset the port before configuring it */
    CSL_SGMII_doSoftReset (macPortNum);

    while (CSL_SGMII_getSoftResetStatus (macPortNum) != 0)
    {

    }


//    To connect with an external PHY, the PHY will be the master, and the SGMII module needs to be
//    configured in slave mode.

    
         if (macPortNum < 4) {
        /* Hold the port in soft reset and set up
         * the SGMII control register:
         *      (1) Disable Master Mode
         *      (2) Enable Auto-negotiation
         */
        CSL_SGMII_startRxTxSoftReset (macPortNum);
        CSL_SGMII_disableMasterMode (macPortNum);
        CSL_SGMII_enableAutoNegotiation (macPortNum);
        CSL_SGMII_endRxTxSoftReset (macPortNum);

        /* Setup the Advertised Ability register for this port:
         *      (1) Enable Full duplex mode
         *      (2) Enable Auto Negotiation
         *      (3) Enable the Link
         */
        sgmiiCfg.linkSpeed      =   CSL_SGMII_1000_MBPS;
        sgmiiCfg.duplexMode     =   CSL_SGMII_FULL_DUPLEX;
        CSL_SGMII_setAdvAbility (macPortNum, &sgmiiCfg);

        NIMU_drv_log1("Waiting SGMII-linkUp and negotiation....macPortNum:%d\n", macPortNum);
        do
        {
            CSL_SGMII_getStatus(macPortNum, &sgmiiStatus);
	    timeout--;
           
        } while ((sgmiiStatus.bIsLinkUp != 1) && (timeout>0));
     

        /* Wait for SGMII Autonegotiation to complete without error */
        timeout = 1000;
        do
        {
            CSL_SGMII_getStatus(macPortNum, &sgmiiStatus);
	    timeout--;
            if (sgmiiStatus.bIsAutoNegError != 0)
            {
                NIMU_drv_log1("ERRORE bIsAutoNegError  macPortNum:%d\n", macPortNum);
                return; /* This is an error condition */
            }
            
        } while ((sgmiiStatus.bIsAutoNegComplete != 1)&& (timeout>0));

       NIMU_drv_log1("SGMII-linkUp and negotiation succesfull macPortNum:%d\n", macPortNum);
        
    }

    
    /* All done with configuration. Return Now. */
    return;
}

Call Init_MAC for all the port numbers, but I dont have clear in mind what mac address use for each port.... I use different MAC for each port, is that right?

uint8_t cppiMac [6] = {0x00, 0x01, 0x02, 0x03, 0x04, 0x05};

Init_MAC (0, cppiMac, mtu);

cppiMac[0] = 0x01;
Init_MAC (1, cppiMac, mtu);

cppiMac[0] = 0x02;
Init_MAC (2, cppiMac, mtu);

cppiMac[0] = 0x03;
Init_MAC (3, cppiMac, mtu);

I put the following code at the end of the function Init_Switch()

int portNum;
CSL_CPSW_ALE_PORTCONTROL        alePortControlCfg;
for (portNum=0; portNum<4; portNum++)
{
    
    alePortControlCfg.portState             =   ALE_PORTSTATE_FORWARD;
    alePortControlCfg.dropUntaggedEnable    =   0;
    alePortControlCfg.vidIngressCheckEnable =   0;
    alePortControlCfg.noLearnModeEnable     =   0;
    alePortControlCfg.mcastLimit            =   0;
    alePortControlCfg.bcastLimit            =   0;

    CSL_CPSW_setAlePortControlReg (portNum, &alePortControlCfg);
}

Running the software i have the following results:

cable plugged into PORT_0: Board power on --> sgmiiStatus.bIsLinkUp = 1, gmiiStatus.bIsAutoNegComplete=1 --> ping ok!
cable plugged into PORT_1: Board power on --> sgmiiStatus.bIsLinkUp = 1, gmiiStatus.bIsAutoNegComplete=1 --> ping NOT ok!
cable plugged into PORT_2: Board power on --> sgmiiStatus.bIsLinkUp = 1, gmiiStatus.bIsAutoNegComplete=1 --> ping NOT ok!
cable plugged into PORT_3: Board power on --> sgmiiStatus.bIsLinkUp = 1, gmiiStatus.bIsAutoNegComplete=1 --> ping NOT ok!

I'm still not able to ping port 1,2,3

other tweak to do?

Thanks

Fabio

Hi Fabio,

I am comparing your changes with nimu_eth.c file. For K2H, the nimu_eth.c to be updated is under v2 folder "pdk<ver>\packages\ti\transport\ndk\nimu\src\v2". 

Are you modifying the correct version of nimu_eth.c?

Please let me know.

Thanks

Hi Aravind

Yes, I use nimu_eth.c  v2 as starting point

Fabio

Hi Fabio,

Another question.. Are you looking for concurrent usage on all eth ports OR any one port at a given time?

Below NDK user guide would be useful for you to refer to update the NIMU layer.

Hi

I want to use one port at a given time

For example:

1) Eth cable plugged into port0 --> board power on --> send/receive pkt to/from ARM  ----> board power off

2) Remove cable from port 0 and plug into port1  --> board power on --> send/receive pkt to/from ARM  ----> board power off

Fabio

Hi Aravind

Thank you, solved
