但是如果基于Kria SOM starter kits板卡生成lwip echo server application并生成“BOOT.BIN”,将“BOOT.BIN”更新到qspi flash之后启动,会发现lwip echo server application 无法link,ping测试也失败。 这是因为Kria SOM starter kits的基板上有ethernet PHY芯片,而PHY address pin和一些数据信号复用,这些管脚通过板上pul...
ST官方例程文件包含了中断引脚的相关配置,主要用于指示接收到以太网帧,我们这里不需要使用,采用无限轮询方法检测接收状态。stm32f4x7_phy.h文件存放相关宏定义,包含RMII和SMI引脚信息等宏定义,其中要特别说明的有一个宏,定义了PHY地址:ETHERNET_PHY_ADDRESS,这里根据硬件设计设置为0x00,这在SMI通信是非常重要的。
