NDK 2.0 CFGDEMO 无法连接 无法PING通

NDK 2.0有个bug, 不能和100M网口连, 具体请参考下面的FAQ.

processors.wiki.ti.com/.../Network_Developers_Kit_FAQ

我确认板子是工作在  1000M 模式下    ，  

追踪程序  发现 CFGDEMO.c  文件中

static void GetIP( uint IfIdx )  

   while(1)

   {

       // Receive ICMP packet data

       fromlen = sizeof(from);

       cc = (int)recvfrom( s, pBuf, MAXPACKET, 0, (PSA)&from, &fromlen );

       if( cc < 0 )

           goto abort;

recvfrom  无法运行下去  老是在接收？

请问打过补丁了吗?

software-dl.ti.com/.../index_FDS.html

设置的最大packet length是多少?

打过补丁了

#define MAXPACKET 1500 // max packet size

static void GetIP( uint IfIdx )

fromlen = sizeof(from);  

fromlen = 16？ 才16个？

请试试将ISR中的printf() 去掉或者用LOG_printf()替代

汗  ISR 在哪个文件 路径？

ISR是中断服务子程序的缩写(Interrupt Service Routine)

根据我自己的经验，C6455网络启动后，用PC机确实是PING不通的，即使C6455和PC机之间网络连接确实正常。我理解这有可能是因为C6455的网络缓冲区设置问题  还请大牛点拨

NDK 2.0  跟1.92 版本相比  底层函数 根本性不同  有些封在 STACK 库里  ，  没法调 ，  只能放弃 NDK

你好，

你的问题解决了吗？

我也碰到了同样的问题，

1000M全双工能协商成功，但是ping不通。

能否指点一二？

同样ping不通，请教一下怎么解决的？谢谢！
