AM2432: Unable to ping with ICSSG0 when using ICSS-EMAC

Hi  Dupuit Cyril 

Thanks for your query,

I would need more info here:

1. Which phy are using, have you configured them in your application

2. Is your application building properly?

Hi,
We are using a DP83826E. I tested by using the loopback Far-End (Reverse) Loopback feature and I see packets.
The PHY used returns a link up.

My application builds correctly.

The configuration of the PHYs is made by using ETHPHY Device "CUSTOM"; Custom Device Name "DP83826E" in syscfg.
I checked PHYs IDS (and link status when cable is plugged or not).

Here is the generated .syscfg file

/**

Let me know if you need something else or if something is not clear.

Sorry, I forgotten to ask you the following question: EIP PRU firmware is compatible between ICSSG0 and ICSSG1 ?

It is loaded by using the following code:

static int32_t protocol_pru_fw(PRUICSS_Handle pruicssHandle)
{
    int32_t firmwareLoad_done = SystemP_FAILURE;

    /*Load the firmware*/
    PRUICSS_disableCore(pruicssHandle, ICSS_EMAC_PORT_1 - 1);
    PRUICSS_disableCore(pruicssHandle, ICSS_EMAC_PORT_2 - 1);

    if(PRUICSS_writeMemory(pruicssHandle, PRUICSS_IRAM_PRU(0) , 0, (uint32_t *) PRU0_FIRMWARE_NAME, sizeof(PRU0_FIRMWARE_NAME)))
    {
        if(PRUICSS_writeMemory(pruicssHandle, PRUICSS_IRAM_PRU(1) , 0, (uint32_t *) PRU1_FIRMWARE_NAME, sizeof(PRU1_FIRMWARE_NAME)))
        {
            firmwareLoad_done = SystemP_SUCCESS;
            PRUICSS_enableCore(pruicssHandle, ICSS_EMAC_PORT_1 - 1);
            PRUICSS_enableCore(pruicssHandle, ICSS_EMAC_PORT_2 - 1);
        }
    }

    return (firmwareLoad_done);
}

Yes, EIP firmware is compatible for both ICSSG0 and ICSSG1.

I see you have enabled mdio manual mode. SO could you please check if the emulated MDIO register detect the phy alive and link register. This you can check using memory browser at address 0x3009FF00

Hi,
I checked address (ICSSG1) 0x3009FF00 and it returns:

Is it possible that I misconfigured DMA accesses (RX interrupts are generated)?

Best regards,

Cyril

I discovered that unicast and broadcast are not received.

But, multicast packets are partially received (the first 4 bytes of the destination address are missing).

The remaining bytes are valid:

TX: 01 00 5E 7F FF FA C8 5A CF 0C 23 57 08 06 00 01 08 00 06 04 00 01 C8 5A CF 0C 23 57 C0 A8 01 CC 00 00 00 00 00 00 C0 A8 01 0A
RX:                     FF FA C8 5A CF 0C 23 57 08 06 00 01 08 00 06 04 00 01 C8 5A CF 0C 23 57 C0 A8 01 CC 00 00 00 00 00 00 C0 A8 01 0A

Good to know PHY is working properly.

No, HSR-PRP driver does not use DMA.

I only have one port plugged (pru0).

I disabled storm protection at initialization phase.

The strange thing is that version and version2 of PRUs are empty. Is it normal?

Versions and features are correctly set. But packets are not received or transmitted.

Best regards,

I changed the function used to load EIP firmware to be able to get PRU firmware version as follow:

static int32_t protocol_pru_fw(PRUICSS_Handle pruicssHandle)
{
    int32_t firmwareLoad_done = SystemP_FAILURE;
    int32_t status;

    status = PRUICSS_resetCore(pruicssHandle, PRUICSS_PRU0);
    DebugP_assert(SystemP_SUCCESS == status);
    status = PRUICSS_resetCore(pruicssHandle, PRUICSS_PRU1);
    DebugP_assert(SystemP_SUCCESS == status);

    /*Load the firmware*/
    status = PRUICSS_disableCore(pruicssHandle, PRUICSS_PRU0);
    DebugP_assert(SystemP_SUCCESS == status);
    status = PRUICSS_disableCore(pruicssHandle, PRUICSS_PRU1);
    DebugP_assert(SystemP_SUCCESS == status);

    if(PRUICSS_writeMemory(pruicssHandle, PRUICSS_IRAM_PRU(0) , 0, (uint32_t *) PRU0_FIRMWARE_NAME, sizeof(PRU0_FIRMWARE_NAME)))
    {
        if(PRUICSS_writeMemory(pruicssHandle, PRUICSS_IRAM_PRU(1) , 0, (uint32_t *) PRU1_FIRMWARE_NAME, sizeof(PRU1_FIRMWARE_NAME)))
        {
            firmwareLoad_done = SystemP_SUCCESS;
            status = PRUICSS_enableCore(pruicssHandle, PRUICSS_PRU0);
            DebugP_assert(SystemP_SUCCESS == status);
            status = PRUICSS_enableCore(pruicssHandle, PRUICSS_PRU1);
            DebugP_assert(SystemP_SUCCESS == status);
        }
    }

    return (firmwareLoad_done);
}

Now, I always have a filled version/version2.

Unfortunately, packets are still not sent/received correctly...

Cyril

Hi Cyril,

Couple of question on this

1) Do you see the Rx interrupt is getting hit? - From the previous replies it looks like this is happening, could you confirm this anyways?

2) Could you share ICSS Memory dump between ICSSG0 and ICSSG1 once the application is loaded (Without connecting the Link on any ports)

3) pru.txBcast 6
    pru.txOctets 384

    Looks like firmware sends out some packet on wire. Did you capture from the interface to verify the packet is on the wire or not?

Regards,
Prajith

Hi Jayarajan,

1) Yes, Rx interrupt is generated. The received frames are coming from the receive callback.

3) Yes, firmware is trying to send packets (arp broadcast/unicast packets) when link comes.

2)DRAM0.datDRAM1.dat

Here is the dump asked.

Hope it helps. Let me know if you need something else.

Best regards,

Cyril

HI Prajith Jayarajan,

Do you have an update about the file shared by Cyril last week ? 

Thanks

Christophe.

Hi,
Did you have time to investigate this issue?

Best regards,
Cyril

The changes that were implemented to support the custom board were: 

• ICSS instance (from 1 to 0)
• PHY addresses changed to [0; 2]
• EDC_LATCH_IN0 disabled
• EDC_SYNC_OUT0 disabled
• Changed CONFIG_ETHPHY0 to CUSTOM (Custom Device Name set to DP83826E)
• Changed CONFIG_ETHPHY1 to CUSTOM (Custom Device Name set to DP83826E)
• Enable “CONFIG_ICSS_EMAC0 Learning Enable”

Disable unnecessary components from “.syscfg” file:

• I2C
• GPIO
• EEPROM

File modification:

• hsr_prp_soc.c:
  • hsrprp_rgmii_init()
    • Surround this function with #ifdef HSR_PRP_RGMII/ #endif
• \source\board\makefile.am243x.r5f.ti-arm-clang:
  • Add “ethphy_dp83826e.c”
  • Compile sdk by using the following command:
    • gmake libs PROFILE=debug

#hsr_prp_soc.c 
#ifdef HSR_PRP_RGMII
void hsrprp_rgmii_init()
{
    ETHPHY_DP83869_LedSourceConfig ledConfig;

    …


    hsrprp_configure_rat();

Hi,
Here is the requested dump asked by Daviel.

Hope it helps,

Cyril

Hi,

I modified today's sample code by adding multicast filtering configuration.

icssEmacParams.pruicssIntcInitData = &pruss_intc_initdata;
icssEmacParams.fwStaticMMap = &(icss_emacFwStaticCfgLocal[1]);
icssEmacParams.fwDynamicMMap = &icss_emacFwDynamicCfgLocal;
icssEmacParams.fwVlanFilterParams = &icss_emacFwVlanFilterCfg;
icssEmacParams.fwMulticastFilterParams = &icss_emacFwMulticastFilterCfg;
icssEmacParams.pruicssHandle = prusshandle;

With this new line, I can see rx interrupt (I mean, the same behavior we have with the POC)
Cyril
