MHC/BSP的默认设置是什么？

我一直在拉我的头发在这一个，但现在有一些事情继续下去…我一直在使用UDP Bootloader的例子，（基础），发现，当我把它移植到我自己的硬件，它从来没有工作。我仔细地查看了各种不同的雕塑作品。我找不到任何有意义的东西…所以我开始研究“不明智”的事情。在我的设置中，IP是静态的。我添加了ICMP，所以我可以ping这个设备，它工作得很好，所以我们知道IP /以太网都是OK。我发现UDP套接字工作的唯一时间是IPIP地址和网关地址相同的地方。真奇怪。如果网关与IP地址不一样，套接字将返回无效。我花了一些时间调试这个，并且我发现代码没有传递IP地址，但是它通过网关（DATASERAMUDP.C的第159行），恰好在微芯片示例中，网关。Y和IP地址是相同的。哪一个可能是MHC/BSP的默认设置？现在我已经解决了我现在面临的问题，现在我至少可以采取一些行动，但这是一个尴尬的局面。

    I have been pulling my hair out on this one, but now have something to go on..

I've been using the UDP bootloader example, ( basic ) and found that when ever i ported it onto my own hardware it never worked.. I carefully looked through all the different congfigurations.. i coud'tn find anything that made any sense..   So i started looking at 'non sensible' things.    In my setup the IP is static.   i've added ICMP so, i can ping the device, and it works fine, so we knew that the IP / ethernet was all ok.


What I've found is that the only time that  a UDP socket would work is if the IP_Address and the gateway address where identical.    Truely odd.   If the gateway is not the same as the IP address the socket would return as invalid.

I spent some time debugging this, and i've found that the code is not passing the IP address, but its passing the gateway ( line 159 of datastream_udp.c )

udpsocket = TCPIP_UDP_ServerOpen(IP_ADDRESS_TYPE_IPV4,



                                 port,
                                (IP_MULTI_ADDRESS*) &laddr);

it just so happens that in the microchip examples, the gateway, and the ip address are the same. which might be the default setup from the mhc/bsp?

I have sorted out enough now to solve my immediate problem, and i can now at least move on somewhat, but this is bizzare.
