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);
