skyeye+ucos+lwip

wanh17

我在SKYEYE下实现LWIP的时，
启动SKYEYE并load lwip_on_ucos_test.elf后，一切正常；（main_entry.c）程序运行在
void usr_task(void * pParam)
{
  PRINT("\nusr_task:hello!\n");
  while(1){
    sleep(5);     <----------程序运行在这里
   }
}

现在遇到一个问题：我打开另外一个SHELL，$ telnet 10.0.0.1 7后运行画面没有任何反应。(SKYEYE.CONF文件中HOSTIP=10.0.0.1)

i forget to run tun driver module:
  #ismod /lib/modules/2.4.x/kernel/drivers/net/tun.o
then it's ok!

But there have other problem:I normally run it once!

我还有个问题：如果已经实现了UCOSII在某个ARM芯片上运行(LWIP也成功移植到UCOSII上)，现在想把LWIP＋UCOS移植到该芯片上，是否现在所要做的就是写该芯片的网络设备驱动程序？
