Hi,I have encountered several problems and I don't know if it's due to lwIP but
I never encountered any problems whenever I used the function xil_printf.At
some locations in my code, if I use this function, the server is behaving in a
weird way. I'm using OPB Uartlite and whenever I try to display the content of
avariable, it crashes the server or my echo function is not responding at all.
If I do a text only xil_printf, everything works fine.#include "config.h" //
DEFAULT_PORT#include "global.h" // server_accept()#include "lwip/tcp.h" //
tcp_new(), tcp_bind(), tcp_listen(), tcp_accept()#include <stdlib.h>#include
<stdio.h>#include <string.h> #include "lwip/debug.h"#include
"lwip/stats.h"#include "xparameters.h"err_t server_accept(void *arg, struct
tcp_pcb *pcb, err_t err){ struct connection_state *cs; /* Allocate memory
for the structure that holds the state of the connection. */ cs =
mem_malloc(sizeof(struct connection_state)); if(cs == NULL) {
xil_printf("could not malloc memory for server_state\r\n"); return ERR_MEM;
} /* Initialize the structure. */ cs->data = NULL; cs->left = 0; /* Tell
TCP that this is the structure we wish to be passed for our callbacks. */
tcp_arg(pcb, cs); /* Tell TCP that we wish to be informed of incoming data by
a call to the http_recv() function. */ tcp_recv(pcb, server_recv);
tcp_err(pcb, server_err); tcp_poll(pcb, server_poll, 1);
xil_printf("Connection established with client %s on port %d.\r\n",
getRemoteHostAddress(pcb->remote_ip), (int)(pcb->local_port)); return
ERR_OK;}The getRemoteHostAddress is char*. Thanks for your help,Antoine.
