TDA4VM: TDA4VM Rtos 0902: Ethfw AUTOnegotition and master ?

Tool/software:

Hi ,
    TDA4VM RTOS 0902

    when I test mac 2 mac , only 
close all option to Board A and Board B , that mac 2 mac can be work well.

Are there other combinations?

//CSL_SGMII_enableMasterMode(sgmiiRegs, portNum);
//CSL_SGMII_disableMasterMode(sgmiiRegs, portNum);
//CSL_SGMII_disableAutoNegotiation(sgmiiRegs, portNum);
//CSL_SGMII_enableAutoNegotiation(sgmiiRegs, portNum);

    

    else if (sgmiiMode == ENET_MAC_SGMIIMODE_SGMII_FORCEDLINK)
    {
        ENETTRACE_DBG("MAC %u: Configure SGMII in SGMII_FORCEDLINK mode", portId);

        CpswMacPort_mapSgmiiLinkCfg(&sgmiiAdvAbility, linkCfg);
        sgmiiAdvAbility.bLinkUp   = 1U;
        sgmiiAdvAbility.sgmiiMode = CSL_SGMII_MODE_SGMII;

        CSL_SGMII_setAdvAbility(sgmiiRegs, portNum, &sgmiiAdvAbility);
        //CSL_SGMII_enableMasterMode(sgmiiRegs, portNum);
        //CSL_SGMII_disableMasterMode(sgmiiRegs, portNum);
        //CSL_SGMII_disableAutoNegotiation(sgmiiRegs, portNum);
        //CSL_SGMII_enableAutoNegotiation(sgmiiRegs, portNum);

        /* Wait for SGMII link */
        if (linkCfg->speed != ENET_SPEED_10GBIT)
        {
            do
            {
                CSL_SGMII_getStatus(sgmiiRegs, portNum, &sgmiiStatus);
            }
            while (sgmiiStatus.bIsLinkUp != 1U);
        }

        status = ENET_SOK;
    }

thanks

    If it was MAC2MAC it would work on below as well.

    One side master and other slave. 

    Both master also would work

    Hi,

    From above register dump I could you are checking SerDes0.

    Can you please dump the SerDes registers in working scenario? Also, can you please confirm is there switch/PHY connected to CPSW Port or It's TI Board 2 TI Board?

    We have tested TI Board to TI Board. We haven't tested with any other PHY/Switch.

    Best Regards,
    Sudheer

    ******

    update:

    when  //CSL_SGMII_setAdvAbility(sgmiiRegs, portNum, &sgmiiAdvAbility); 
    then mac 2 mac the master 2 master work well......

    and 

    when 
        open CSL_SGMII_enableAutoNegotiation(sgmiiRegs, portNum);

    then  all can't pinged.

    //CSL_SGMII_setAdvAbility(sgmiiRegs, portNum, &sgmiiAdvAbility); 

    //CSL_SGMII_enableAutoNegotiation(sgmiiRegs, portNum);

    then Master and slave is ok.

    Are there any other options?

    So. by my test, 

    thanks

    Hi,

    In RTOS test, we are not enabling Auto negotiation, but we set advertise ability with speed & duplexity and keep SGMII in master mode.

    I am not sure whether such long wires to use for MAC2MAC connection. We internally have Bridge Board to connect one to one very closely and use it for test purpose.

    So, we are expecting it should work in your setup as well with minimal length cables.

    Best Regards,
    Sudheer
