TDA4VM: CPSW9G communication on A72 with QNX

TDA4VM: Query on CPSW9G communication on A72(QNX) with Static IP

Part Number: TDA4VM

Hello Team,

                   We are trying to communicate to QSGMII ports on TDA4VM Eval board through CPSW9G on A72(QNX). One of the QSGMII port is

connected to PC using a BAFO connector(Ethernet to USB) and we are trying to set a static IP.

We did the below modifications to 8.2 versions of RTOS(for ethernet firmware) and QNX SDK.

RTOS SDK(For enabling QSGMII and static IP),

1. ti-processor-sdk-rtos-j721e-evm-08_02_00_05\ethfw\apps\app_remoteswitchcfg_client\mcu_2_1\main.c

#define ENABLE_QSGMII_PORTS              // Enable QSGMII ports

#define ETHAPP_LWIP_USE_DHCP   (0)   // Disable DHCP

2. ti-processor-sdk-rtos-j721e-evm-08_02_00_05\pdk_jacinto_08_02_00_21\packages\ti\drv\enet\examples\utils\makefile


- ifeq ($(SOC),$(filter $(SOC), j721e))
- ENET_CFLAGS += -DENETAPPUTILS_BYPASS_QSGMII
- endif

3. ethfw/apps/app_remoteswitchcfg_server/mcu_2_0/ndk.cfg 

  enableStaticIP   = 1;

QNX SDK(For enabling QSGMII and static IP),

1. psdkqa/qnx/devnp/src/enetlld_if.c

static Enet_MacPort gRemoteAppMacPorts[] =
{
#if defined (SOC_J721E)
    /* configuration based on GESI board */
    // ENET_MAC_PORT_1,
    // ENET_MAC_PORT_3,
    //ENET_MAC_PORT_4,
    //ENET_MAC_PORT_8,
    /* configuration based on QSGMII board */
    ENET_MAC_PORT_2, /* QSGMII main */
    ENET_MAC_PORT_5, /* QSGMII sub */
    ENET_MAC_PORT_6, /* QSGMII sub */
    ENET_MAC_PORT_7, /* QSGMII sub */
#elif defined (SOC_J7200)
    /* configuration based on Quad-Port Eth Expansion board */
    ENET_MAC_PORT_1,
    ENET_MAC_PORT_2,
    ENET_MAC_PORT_3,
    ENET_MAC_PORT_4,
#endif
};

2. psdkqa\qnx\scripts\bsp\710_SVN948724_JBN57\images\j721e-evm-ti.build

ifconfig am0 169.254.1.2 //Static IP

We rebuild the ethfw, enet LLD and loaded the firmware on R5 core(MCU2_0).

Build commands are,

  • "make enet_clean"
  • "make enet"
  • "make ethfw_all_clean"
  • "make ethfw_all BUILD_SOC_LIST=J721E BUILD_QNX_A72=yes"

After loading the ethernet firmware from uboot the QSGMII PHY are detected and we got Link Up in MCU2_0 console.

Also got a static IP, 192.168.1.200

Then we loaded the QNX from uboot and got the below print in MCU2_0 console,

Function:CpswProxyServer_registerIpv4MacHandlerCb,HostId:0,Handle:a2a7e084,CoreKey:38acb7e6, MacAddress:70:ff:76:1d:92:c1 IPv4Addr:169.254.1.2

Then in the A72(QNX) console we tried, ifconfig -v and got inet as 169.254.1.2.

Then we tried,

1) A72 to PC

    ping  169.254.1.1    // 169.254.1.1  is the IP set on the PC side where QSGMII port is connected.

2) PC to A72(on PC command prompt)

    ping  169.254.1.2

Got the error like, ping: sendto: Host is down  

What could be the possible reason why ping is failing? Do we need to do any other changes in software(ETHFW/QNX) or any other settings needs to be changed?

Attaching our logs from both A72 and R5..

    Hi,

    Can you try to change the MCU2_1 static IP from 192.168.1.200 to 169.254.1.x so it is on the same subnet as A72 and PC?

    Regards,
    Stanley

    Hello Stanley,

                          Thanks for replying. I tried changing the MCU2_0(ETHFW) static IP from 192.168.1.200 to 169.254.1.3. Still I am not able to ping A72(QNX) from PC. Now the IP address are below,

    PC   : 169.254.1.1

    A72 : 169.254.1.2

    R5(MCU2_0)   : 169.254.1.3

     

    After loading the ethernet firmware if we try pinging R5 core from PC its working.

    ping 169.254.1.3   //working

    But after loading and running QNX on A72 the ping is not working for both A72 and R5.

    ping 169.254.1.3   //not working

    ping 169.254.1.2   //not working

     

    Do you have any idea why this is happening?

    Regards,

    Nideesh

    Hi,

    Sorry for delayed response.

    As per above observation, Issue could be configuration of SerDes at U-boot and QNX side but it is already configured from Ethernet Firmware.

    Can you please disable SerDes configuration from u-boot and QNX by referring to FAQ.

       (OR)

    You can try by setting u-boot environment variable and ignore all above/your changes.

    1. Stop booting at u-boot and follow as below.

    • printenv
    • setenv dorprocboot 1
    • saveenv
    • Power off & on

    Best Regards,

    Sudheer
