不能打开TCP客户端或服务器

使用MHC配置TCP/IP协议栈吗？发送StysCyFig .h设置。您为项目分配了哪些堆？

    Do you configure the TCP/IP stack using MHC?
Send the system_config.h settings.
What heap do you have allocated for your project?

你的项目有多大？试着把它和TCP/IP堆增加10 KB，看看会发生什么。如果你有一个附加的系统，你可以试试“HeAPFipe”和“Mac”命令。



      以下为原文

    What heap do you have for your project?
Try increasing it and the TCP/IP heap too by 10 KB, just to see what  happens.
If you have a serial console attached to your system, please try the "heapinfo" and "macinfo" commands.
 

嘿，雷诺德，我去上班了。我的堆分配问题是因为我执行TCPIPPTCP连接方式太快和频繁。我所需要做的就是等待10-15秒，直到堆栈在调用TCPIPPUTCPUnLink之前完全运行并运行，在这种情况下，它成功了，并且套接字开始连接。我的程序不是很干净，我只是设置一个计数器以达到一个特定的值，但它似乎是上升和运行。谢谢你的帮助。

    Hey rainad, so I got it to  work.  My heap allocation problem was because I was performing TCPIP_TCP_Connect WAY too quickly and frequently.  All I needed to do was wait 10-15 seconds until the stack was fully up and running before calling TCPIP_TCP_Connect in which case it was successful and the sockets became connected.  My procedure is not very clean, I just set a counter to reach a specific value, but it seems to be up and running.  Thanks for your help.

很高兴听到它现在起作用。你可以使用TecPIPStaskNeTraseRead（）调用而不是计数器。

    Good to hear it works now.
You can use the TCPIP_STACK_NetIsReady() call rather than a counter.
