Hi,

 

 I wrote a simple TCP-server program base on Rowley webserver demo (from FreeRTOS website) using lwip for ARM7. To test my server, I use Telnet from Windows.

 

But I have a problem with this part of my code :

 

-----------------------------------------------------------------

portCHAR *pcRxString;

char * command;

 

for(;;)

{

    pxRxBuffer = netconn_recv( pxNetCon );

 

    if( pxRxBuffer != NULL )
    {

        netbuf_data( pxRxBuffer, ( void * ) &pcRxString, &usLength );

        strcat(command, pcRxString);

 

        /* Do something special */

 

        netbuf_delete( pxRxBuffer );

    }

}

-----------------------------------------------------------------

 

In Telnet, when I hit a caracter, the server receive the data, copy it in the command array and wait the next caracter. When I hit a second caracter, the server freeze in netbuf_data function, precisely at buf->ptr->payload.

 

Did someone know why ? How can I correct this ?

 

Regards
