MCB52233 - INicheLite - Server TCP mode - calloc1 failed

[Axboeg]

Hi,

I'm trying to make a very simpel program with the MCB52233 to act as a TCP socket listener and display the data coming in on the UART and then close the connection afterwards.

I've downloaded the latest version of the InterNiche TCP/IP Lite stack (Version 3.0) and the CW (Version 7.1).

When I do this simple task:

void emg_tcp_rx( void )

{

            static int length, i;
            unsigned long rate;

            // PARAM1: M_SOCK socket,
            // PARAM2: char * buffer
            // PARAM3: unsigned length
            //
            // RETURNS: number of bytes actually read, or -1 if error.
            // int m_recv(M_SOCK so, char * buf, unsigned buflen)
  // printf ("emg_tcp_rx Enter\n");
   
            length = m_recv( emg_tcp_communication_socket, (char *)buffer, RX_BUFFER_SIZE );
   
   
            if( length > 0)
            {
              buffer[length] = '\0';
                 if(buffer[0]== 0x0d)
                  printf("\n");
                 else
                 {
                  printf("%s",buffer);
                  if(buffer[length-1]==0x0d)
                  {
                   printf("\n");
                  }
                 }

                // m_send(emg_tcp_communication_socket,(char *)buffer,length); //FSL echo back data
            }
}

...my text comes out on the UART the first 25 times (using a .NET program to act as client to create a TCP socket and send "Hello World" and then close the connection) - after this I get this error:

"calloc1 failed: size: 124, failures: 1"

.....this will then make the program unable to communicate anymore!

What I'm I doing wrong here?

Best Regards

Found it!

The so socket is never closed, this line is missing in the freescale_tcp_cmdcb function:

 case M_CLOSED: 
      while( semaphore ){};
      semaphore = 1;
   emg_tcp_communication_socket = INVALID_SOCKET;
   m_close(so);   <----------------------------- ******* this line is missing in the Freescale_TCP_server.c
   semaphore = 0;
       break;
