Hi,

For this MQX version there is a bug in the PPP driver. We found that PPP RX Task was not finishing correctly after PPP_shutdown. To correct we added in PPP_CFG a flag that finalize for RX Task to exit graceful instead destroy task using RTCS_task_destroy in PPP_shutdown.

We modified  the _iopcb_ppphdlc_read and removed some "dead locks" that could occurs during read from pcb device. After this modification the application should connect and disconnect with no problems.

I strongly suggest switch to the latest version of MQX, you can download it from the following link:

Have a great day,
Sol

Hi sol,

Thanks for your reply,

I have upgraded mqx version 3.5 to 3.8.

I am able to have PPP connection but unable to ping PPP server IP or even start telnet or ftp .

I have pasted the code that i have written :-

    uint_32           error;

    _ip_address       peer_address=0; //address will be assigned by remote host

    IPCP_DATA_STRUCT  ipcp_data;

    _PPP_PAP_LSECRET = &lsecret;

    _PPP_PAP_RSECRETS  = NULL; /* rsecrets  */

    _PPP_CHAP_LNAME    = NULL; /* localname */

    _PPP_CHAP_LSECRETS = NULL; /* lsecrets  */

    _PPP_CHAP_RSECRETS = NULL; /* rsecrets  */

    /* Install a route for a default gateway */

    RTCS_gate_add(GATE_ADDR, INADDR_ANY, INADDR_ANY);

    pio = _iopcb_ppphdlc_init(ppp_handler);

    _PPP_ACCM = 0;

    error = PPP_initialize(pio, &phandle);

    if (error)

    {

       printf("\nPPP initialize: %lx", error);

       _task_block();

    } /* Endif */

    _iopcb_open(pio, PPP_lowerup, PPP_lowerdown, phandle);

    error = RTCS_if_add(phandle, RTCS_IF_PPP, &ihandle);

    if (error)

    {

       printf("\nIF add failed, error = %lx", error);

       _task_block();

    } /* Endif */

    _lwsem_create(&ppp_sem, 0);

    _mem_zero(&ipcp_data, sizeof(ipcp_data));

    ipcp_data.IP_UP              = PPP_linkup;

    ipcp_data.IP_DOWN            = PPP_linkdown;

    ipcp_data.IP_PARAM           = &ppp_sem;

    ipcp_data.ACCEPT_LOCAL_ADDR  =  FALSE ;

    ipcp_data.ACCEPT_REMOTE_ADDR = FALSE ;

    ipcp_data.DEFAULT_ROUTE      = TRUE;

    _time_delay(1500);

    error = RTCS_if_bind_IPCP(ihandle, &ipcp_data);

    if (error)

#if PPP_DEVICE_RAS

    error = 0; /* 10 attempts to connect */

    while (error < 10)

    {

        if (PPP_link == FALSE)

        {

          _time_delay(1000);

          printf("time = %d\n",error);   

        }

        else

        {

            printf("\nPPP_link = %d, time = %d\n",PPP_link,error);

            break;

        }

        error ++;

    }

    if (PPP_link == TRUE)

    {

        local_address = IPCP_get_local_addr(ihandle);

        peer_address = IPCP_get_peer_addr(ihandle);

        printf(" Now PPP connection is established on %d.%d.%d.%d\n", IPBYTES(peer_address));

    }

    else

    {

        _lwsem_post(&ppp_sem);       

    }

#endif /* PPP_DEVICE_RAS */

    _lwsem_wait(&ppp_sem);

    if (PPP_link == TRUE)

    {

        return (phandle);

    }

    else

    {

        return(phandle);

    }
