有没有APM32F107RC以太网问题

xiaoqilo2025-04-13

开发板用的的是PD8、PD9、PD10复用引脚，我板子上用的是PA7、PC4、PC5不管怎么调就是不好使，确认PHY正常运行通过MDIO可以读取到PHY状态，以下是初始化代码：void Ethernet_GPIOConfig(void)
{
GPIO_Config_T configStruct;
/*

* ETH_INT                            PB14
* ETH_MDIO                         PA2
* ETH_MDC                            PC1
* ETH_MCO                            PA8
