NUCLEO - H743ZI 网络问题 Niche Stack ucos ii Freertos
最近在移植 niche stack 网络协议栈，用的操作系统是 ucos ii ,硬件平台是 NUCLEO H743ZI遇到了一些问题请教一下各位。现象：用ATKKPING 做PING测试。按下复位键单片机开始运行,PING时间<1ms,过了一会就会PING不通，或者PING延时非常高。以上是在我去掉 FTP 、TELNET、 PINGAPP 等一些无关任务后做的测试。附件是我用 SYSTEM VIEW 抓到的数据。
我也移植到了FREERTOS下但是也遇到了相似问题，所以回到Ucos 下。
下面是我的的 时钟、 MPU、 ETHDSC、接收 发送、 关键代码。

怎么去掉附件 下载扣金币。。。 普通的ping包是64字节的reply，你截图上看到的是1472字节，可以用hub抓包看下实际的包内容和长度。 学习了
