TMDX654IDKEVM: Promiscuous Mode on AM65xx

Stef

Part Number: TMDX654IDKEVM

Hi,

while testing the TI-RTOS based ICSS EMAC loopback application (without DDR) I also tested the promiscuous mode. The test passed and everything seems to be ok.

But, if I have a look at the received messages, broadcast, multicast and a MAC-matched (48:93:fe:fa:18:44) telegram are being received, so the promiscuous mode is not used at all.

If a add a further telegram with a different destination MAC-address 48:93:fe:fa:18:45, I expect to receive this telegram in promiscuous mode. But it doesn't.

Receiver timeout. Is there any issue with promiscuous mode on AM65xx?

Here are the extended parts of test_utils_k3.c. Why does the test message:

app_test_uc_no_match_pkt
 
is not being received in app_test_promiscous_mode ?


... adding:

static uint8_t app_test_uc_no_match_pkt[APP_TEST_PKT_SIZE] = {
    0x48, 0x93, 0xfe, 0xfa, 0x18, 0x45,
    0x48, 0x93, 0xfe, 0xfa, 0x18, 0x4a,
    0x08, 0x06, 0x00, 0x01,
    0x08, 0x00, 0x06, 0x04,
    0x00,0x01,0x01, 0xbb,
    0xcc, 0xdd, 0xee, 0xff,
    0xc0, 0xa8, 0x01, 0x16,
    0x00, 0x00, 0x00, 0x00,
    0xc0, 0xa8,0x01, 0x02,
    0x01,0x02,0x03,0x04,
    0x01,0x02,0x03,0x04,
    0x01,0x02,0x03,0x04,
    0x01,0x02,0x03,0x04,
    0x01,0x02,0x03,0x04,
    0xfe,0xfe, 0x00, 0x00
};

...

void  app_test_promiscous_mode(void)
{
    ... adding:

    pTestPkt = (uint8_t*)(&app_test_uc_no_match_pkt[0]);
    app_test_send_receive(portNum, endPort, 0);
    UART_printf("app_test_promiscous_mode with no match UC  pkt success\n");

     ...
    
}

Hi Stef,

Sorry for the delay in reply.

I am checking internally and will revert to you shortly.

Hi Stef,

Can you try with the attached function for configuring promiscous mode ?

Fullscreen promiscous_enable.txt Download

void app_test_config_promiscous_mode(uint32_t enable)
{
    uint32_t pNum;
    EMAC_IOCTL_PARAMS params;

    for (pNum =portNum; pNum  <= endPort; pNum++)
    {
        if ((!port_en[pNum]) || (pNum == 6))
            continue;
        params.seqNumber = gAppTestSequenceNumber++;

        if(enable)
        {
            params.subCommand =  EMAC_IOCTL_PORT_MC_FLOODING_ENABLE;
        }
        else
        {
            params.subCommand =  EMAC_IOCTL_PORT_MC_FLOODING_DISABLE;
        }

        emac_ioctl(pNum, EMAC_IOCTL_MC_FLOODING_CTRL, (void *)(&params));
        app_test_wait_mgmt_resp(100);

        params.seqNumber = gAppTestSequenceNumber++;

        if(enable)
        {
            params.subCommand =  EMAC_IOCTL_PORT_UC_FLOODING_ENABLE;
        }
        else
        {
            params.subCommand =  EMAC_IOCTL_PORT_UC_FLOODING_DISABLE;
        }

        emac_ioctl(pNum, EMAC_IOCTL_UC_FLOODING_CTRL, (void *)(&params));
        app_test_wait_mgmt_resp(100);
    }
}
