I am trying to run the sample code for tftp server. I get no complaints when synthesizing my hardware or compiling the code. However, when I add the lwip_init() statement, it seems to stop working (it doesn't output any of the print statements). This is very frustrating and I have no idea what is causing it. Any ideas? Thanks
#include <stdio.h>
#include "xenv_standalone.h"
#include "xparameters.h"
#include "platform.h"
#include "netif/xadapter.h"
#include "lwip/init.h"
#define EMAC_BASEADDR XPAR_LLTEMAC_0_BASEADDR
int main()
{
print("-- Starting main() -- \r\n");
struct netif *netif, server_netif;
struct ip_addr ipaddr, netmask, gw;
/* the mac address of the board. this should be unique per board */
unsigned char mac_ethernet_address[] = { 0x00, 0x0a, 0x35, 0x00, 0x01, 0x02 };
netif = &server_netif;
microblaze_init_icache_range(0, XPAR_MICROBLAZE_0_CACHE_BYTE_SIZE);
microblaze_init_dcache_range(0, XPAR_MICROBLAZE_0_DCACHE_BYTE_SIZE);
/* enable caches */
XCACHE_ENABLE_ICACHE();
XCACHE_ENABLE_DCACHE();
platform_setup_interrupts();
/* initliaze IP addresses to be used */
IP4_ADDR(&ipaddr, 192, 168, 1, 10);
IP4_ADDR(&netmask, 255, 255, 255, 0);
IP4_ADDR(&gw, 192, 168, 1, 1);
print_app_header();
print_ip_settings(&ipaddr, &netmask, &gw);
lwip_init();
...
}
EDIT in response to vicky:
maybe you can explain something cause you might be right. When i compile it without lwip_init(), i get:
text data bss dec hex
7214 356 1104 8674 21e2
and with lwip_init() i get:
text data bss dec hex
9726 356 559080 569162 8af4a
which is ALOT bigger. too bad it can't give a warning about this
