httpd application

[saida]

hi i.mx6 community

i am trying to run httpd application from i,mx6_platform_sdk

i made following changes to main routine

1. i commented getting ip by dhcp and auto

2. i enabled getting ip by static

3. i changed ip address 172.22.20.61 and my host is 172.22.20.11

after compilation, when i browse http:172.22.20.61 its not working (no connection error)

plz any one can reply

thanks and regards

First please make sure that httpd accepts the connection.

I mean you should get something like this:

# telnet 172.22.20.61 80

Trying 172.22.20.61...

Connected to woland.iae.nsk.su.

Escape character is '^]'.

running telnet on PC.

If you get no responce you can run telnet on the board itself to make sure that it is not a routing issue.

Then you can perform some simple http request:

# curl http://172.22.20.61/

and see what exactly the httpd returns.

Have a great day,

Victor

what happen if you "telnet" from PC on port 80 ?  Can you try a cross cable ? On netstat -ant, is the http process listening on port 80 ?

hi

i pinged from ubuntu when u-boot is running on target board,

its working and also i tried tftp loading is also working with direct cable but not with cross over cable.

from this i confirmed that it works with direct cable

hi saida,

what code / app are you modifing ?

If you "ip addr show" can you see the correct ip set for the interface ?

What gives "netstat -ant" ?

hi angelo dureghello

thanks for your reply

i am modifying in http_main.c file init_lwip() function .

just give the procedure what i am doing

void init_lwip(void)

{

    lwip_init();

    ip_addr_t addr;

    ip_addr_t netmask;

    ip_addr_t gw;

    IP4_ADDR(&addr, 10, 81, 4, 142);

    IP4_ADDR(&netmask, 255, 255, 255, 0);

    IP4_ADDR(&gw, 10, 81, 7, 254);

#if LWIP_NETIF_HOSTNAME

    g_netif.hostname = "lwip";

#endif

    // Set the MAC address.

    enet_set_mac(kMACAddress);

    // Create the netif.

    netif_add(&g_netif, &addr, &netmask, &gw, NULL, enet_init, ethernet_input);

    netif_set_status_callback(&g_netif, netif_status_callback);

    netif_set_link_callback(&g_netif, netif_link_status_callback);

    netif_set_default(&g_netif);

    dns_init();

    // Wait for link to come up.

    printf("Waiting for link...\n");

    while (true)

    {

#if CHIP_MX6DQ || CHIP_MX6SDL

        uint32_t status = imx_enet_get_phy_status(g_en0);

        if (status & ENET_STATUS_LINK_ON)

#elif CHIP_MX6SL

        uint32_t status = imx_fec_get_phy_status(g_en0);

        if (status & FEC_STATUS_LINK_ON)

#endif

        {

            printf("Ethernet link is up!\n");

            break;

        }

        hal_delay_us(100000); // 100 ms

    }

    // DHCP

    if (1)

    {

        dhcp_start(&g_netif);

    }

    // Auto IP

    else if (0)

    {

        autoip_start(&g_netif);

    }

    // Static IP address

    else

    {

        netif_set_up(&g_netif);

    }

    httpd_init();

    printf("TCP/IP initialized.\n");

}

in this function i am disabling DHCP and Auto IP mode and enabling Static IP way getting IP address

changes

IP4_ADDR(&addr, 172, 22, 20, 61);

IP4_ADDR(&netmask, 255, 255, 255, 0);

IP4_ADDR(&gw, 172, 22,20, 254);
