标题: 以太网无法使用
原理图使用RGMII Crystal 25M for PHY, RGMII_CLK input 125M for TX_CLK连接方式：连接方式和DEMO板一样；硬件连接的GMAC0；
软件按照文档已经配置了；

开机后没有eth0网络；原因就是
rk_gmac-dwmac fe2a0000.ethernet eth0: Could not attach to PHY；开机过程中量不到PHY送给GMAC的125MCLK；原因可能是什么呀？

有大佬帮忙看看吗？

问题根源就是识别不到phy，时钟问题，供电问题，焊接问题，硬件连线错误问题等等一堆都有可能，所以需要你自己排查，什么可能都有，
