Is the description in Chinese ok? This is more accurate, if you need English, we will translate it for you。

 1.使用16M的外部SDRAM作为emwin缓存时,(1366*768*3*2)作为LTDC显示空间,(8192*1024)作为GUI_NUMBYTES分�?给GUI内存。使用当打开�?�缓冲时(RGB565颜色格�?),显示图�?会有定时�?�顿,关闭�?�缓冲正常,但是切�?�图�?时会产生拉窗帘现象。

2.�?�考官方例程移�?LWIP 1.41 LwlP_TCP_Echo_Client,�?使用netconn_connect()函数连接�?务器时,返回结果为ERR_RTE,此时查看网�?��?�侧橙�?�常�?,左侧绿�?�闪�?。使用抓包工具和使用命令行ping机器无法获�?�任何信�?�,如何判断此时的lwip是�?�正常�?始化?

3.LWIP�?�用时,应如何�?置MPU�?护?

4.LWIP使用的内存空间是�?�为AXI RAM?

5.  在调试的时候USB�?�以正常工作,�?�以识别U盘,导出数�?�。断电�?新开机U盘就无法识别,麻烦分�?一下是什么原因。
