[ECOS] porting Web server in Ecos

[Aniket S Joshi]

Dear All,

I am tring to add Goahead Web server Functionality in my Ecos Application.
I am using Sh7729R Hitachi Processor eval board.
Has anyboady added Goahead Web server Functionality in Ecos successfully?
Till this point i am able to download Web Server (Goahead) library with My application on target.. but when i give the command http://<MY Board IP Address> in Internet explorer nothing is happening.

can anybody tell me what could be the problem? OR which area i have to look for?

Thanks in advance

Aniket

Thanks and regards,

Yes.  The demo worked fine for me, and we've since shipped a
lot of units of several different product models that have the
GoAhead web server in them.

Have you tried enabling the diagnostic messages in the web
server?

Have you tried telnetting to the port to see if the server is
listing?

Have you tried using tcpdump or Ethereal to watch the network
traffic.

Have you done any debugging at all?

Various versions of eCos (including 2.0) running on a
half-dozen slightly different ARM7 platforms.

Somewhere you have a defaultTraceHandler() function.  That
function is called by the webserver to log various events.
Change it so it does something useful.  By default, the eCos
demo port has an empty function:

    void defaultTraceHandler(int level, char_t *buf)
    {
    /*
     *      The following code would write all trace regardless of level
     *      to stdout.
     */
    #if 0
      if (buf) {
        write(1, buf, gstrlen(buf));
      }
    #endif
    }

Try changing that to something like this:

    void defaultTraceHandler(int level, char_t *buf)
    {
      diag_printf("%d: %s\n", level, buf);
    }


>>> Have you tried telnetting to the port to see if the server is

> Yes... But no response from the board

The diagnostic output from the trace handler should tell you
what's going on.

I am using ecos 2.0 + Hitachi 7729 Processor combination to port Goahead web server.
Can you pls tell me about your system combination on which Goahed web server is running ?

>>Have you tried enabling the diagnostic messages in the web
>>server?
No, How to enable this Diagnostic option for web server? Do i need to set some #DEFINE for this?
Currently I am using Diagnostic options on ecos configuration tool.

>> Have you tried telnetting to the port to see if the server is
>> listing?
Yes... But no response from the board
But Ping is working fine.
