PROCESSOR-SDK-AM335X: HSR PRP Integration

Hi Vipul Kole,

Sorry for the delayed response,

HSR uses Switch application and PRP uses Dual mac application, so if your using HSR you need to configure it to switch mode , for PRP you need to configure it to dual mac mode.

Basic needs of HSRPRP are HSR-PRP-DAN and PDK.

No need to integrate SNMP to work with HSR-PRP.

Thank you Roopak.

So as per the suggestion we changed the mode to switch, loaded and enabled both PRU (icss_emac_switch.bin)

AS of now we not integrated the hsr code. just checking with the SWITCH mode configuration. 

for that we found that if we do the ping request it is not successful. It is getting stuck at some point of code. while debugging, we found that it stuck in ICSS_EMAC_osalPendLock(((ICSS_EmacObject*)emachandle->object)->txSemaphoreHandle, SemaphoreP_WAIT_FOREVER);

Code Changes:

DUAL_MAC (Working)

switchEmacCfg->phyAddr[0] = BOARD_ICSS_EMAC_PORT0_PHY_ADDR;
switchEmacCfg->portMask = ICSS_EMAC_MODE_MAC1;
switchEmacCfg->ethPrioQueue = ICSS_EMAC_QUEUE1;
switchEmacCfg->halfDuplexEnable = 1;
switchEmacCfg->enableIntrPacing = ICSS_EMAC_ENABLE_PACING;
switchEmacCfg->ICSS_EmacIntrPacingMode = ICSS_EMAC_INTR_PACING_MODE1;
switchEmacCfg->pacingThreshold = 100;
switchEmacCfg->learningEn = 0;
switchEmacCfg->rxIntNum = 20;
switchEmacCfg->linkIntNum = 26;
SOCCtrlGetPortMacAddr1(1, lclMac);
switchEmacCfg->macId = lclMac;
ICSS_EmacInit(emachandle, &pruss_intc_initdata,ICSS_EMAC_MODE_MAC1 | ICSS_EMAC_MODE_DUALMAC);

SWITCH MODE (Not Working)

switchEmacCfg->phyAddr[0] = BOARD_ICSS_EMAC_PORT0_PHY_ADDR;
switchEmacCfg->phyAddr[1] = BOARD_ICSS_EMAC_PORT1_PHY_ADDR;
switchEmacCfg->portMask = ICSS_EMAC_MODE_SWITCH;
switchEmacCfg->ethPrioQueue[ICSS_EMAC_QUEUE1] = 1 ;
switchEmacCfg->ethPrioQueue[ICSS_EMAC_QUEUE2] = 0 ;
switchEmacCfg->ethPrioQueue[ICSS_EMAC_QUEUE3] = 1 ;
switchEmacCfg->ethPrioQueue[ICSS_EMAC_QUEUE4] = 0 ;
switchEmacCfg->halfDuplexEnable = 1;
switchEmacCfg->enableIntrPacing = ICSS_EMAC_ENABLE_PACING;
switchEmacCfg->pacingThreshold = 100;
switchEmacCfg->learningEn = 1;
switchEmacCfg->rxIntNum = 20;
switchEmacCfg->linkIntNum = 26;
ICSS_EmacInit(emachandle, &pruss_intc_initdata, ICSS_EMAC_MODE_SWITCH);

PRU Enable Code

  uint8_t firmwareLoad_done = 0;
    /*Initialize the PCP 2 Q map*/
    initializePCPtoQueueMap(emachandle);

    PRUICSS_pruDisable(pruIcssHandle, ICSS_EMAC_PORT_1 - 1);
    PRUICSS_pruDisable(pruIcssHandle, ICSS_EMAC_PORT_2 - 1);

    if(PRUICSS_pruWriteMemory(pruIcssHandle, PRU_ICSS_IRAM(0) , 0,(uint32_t *) &pru_imem0_rev1_start, &pru_imem0_rev1_end - &pru_imem0_rev1_start))
    {
        if(PRUICSS_pruWriteMemory(pruIcssHandle, PRU_ICSS_IRAM(1) , 0,(uint32_t *)&pru_imem1_rev1_start,&pru_imem1_rev1_end - &pru_imem1_rev1_start))
        {
            rtxc_printf("\nPRU Firmware Load done\n\n\r");
            firmwareLoad_done = TRUE;
        }
    }
     if(firmwareLoad_done)
    {
        int32_t ret_val = PRUICSS_RETURN_SUCCESS;
        ret_val = PRUICSS_pruEnable(pruIcssHandle, ICSS_EMAC_PORT_1 - 1);
        if(ret_val != PRUICSS_RETURN_SUCCESS) {
            rtxc_printf("\r\nPRU0 Failed to enable");
        }
        ret_val = PRUICSS_pruEnable(pruIcssHandle, ICSS_EMAC_PORT_2 - 1);
        if(ret_val != PRUICSS_RETURN_SUCCESS) {
            rtxc_printf("\r\nPRU1 Failed to enable");
        }
    }

Please let us know if any other change is required to work with switch mode

Hi Vipul kole,

The Switch firmware from PDK ($PDK_INSTALL_PATH\ti\drv\icss_emac\firmware) should be used along with the icss_emac as is. But incase of HSR PRP firmware (PRU-ICSS-HSR-PRP-DAN_01.00.05.01 package), the icss-emac should be patched with the patch file provided (PRU-ICSS-HSR-PRP-DAN_01.00.05.01\protocols\pdk_patches).

Based on above details which you have provided it seems you are using switch firmware with patched icss_emac. Can you please confirm this?
This combination of icss emac and firmware is not supported.

Roopak
