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

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);

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 ?

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

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
