cp  httpd     cus531-16m/  -a

cp  net/httpd.c   cus531-16m/

cp  net/httpd.h   cus531-16m/

修改net.c

#ifdef CONFIG_STATUS_LED

#include <status_led.h>

#include <miiphy.h>

#endif

//add by panzidong

#include "httpd.h"

#include "../httpd/uipopt.h"

#include "../httpd/uip.h"

#include "../httpd/uip_arp.h"

#if (CONFIG_COMMANDS & CFG_CMD_SNTP)

#include "sntp.h"

#endif

#if (CONFIG_COMMANDS & CFG_CMD_NET)

#if 0

#define ET_DEBUG

#endif

// add by panzidong

unsigned char *webfailsafe_data_pointer = NULL;

int     webfailsafe_is_running = 0;

int     webfailsafe_ready_for_upgrade = 0;

int     webfailsafe_upgrade_type = WEBFAILSAFE_UPGRADE_TYPE_FIRMWARE;

void NetReceiveHttpd(volatile uchar * inpkt, int len);

extern int do_reset(cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]);

void

NetReceive(volatile uchar * inpkt, int len)

{

// add by panzidong

if(webfailsafe_is_running){

NetReceiveHttpd(inpkt, len);

return;

}

NetRxPkt = inpkt;

NetRxPktLen = len;

et = (Ethernet_t *)inpkt;

从蓝本的net/net.c中将后面三个函数粘贴到此。以#define BUF ((struct uip_eth_hdr *)&uip_buf[0])开头的那段代码。

增加httpd命令：

./include/net.h

/* Initialize the network adapter */

extern int      NetLoop(proto_t);

//add by panzidong

extern int      NetLoopHttpd(void);

extern void     NetSendHttpd(void);

static int netboot_common (proto_t, cmd_tbl_t *, int , char *[]);

// add by panzidong

int do_httpd(cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]){

return NetLoopHttpd();

}

U_BOOT_CMD(httpd, 1, 1, do_httpd, "start www server for firmware recovery\n", NULL);
