标题: firefly3568核心板双网口问题，ETH1可用，ETH0不通
如论坛上类似的问题，核心板插到自制的底板上， eth1能ping通，eth0 attach 失败，自制底板对于双网口相关管脚与开发版底板使用管脚相同
9610.132836] rk_gmac-dwmac fe010000.ethernet eth0: Could not attach to PHY
[ 9610.132871] rk_gmac-dwmac fe010000.ethernet eth0: stmmac_open: Cannot attach to PHY (error: -19)

查到eth0所连的GMAC1, 其中 MDIO 和 MCD 都没有信号时序， reset信号是有的，PHY芯片电源正常。

cat /sys/kernel/debug/pinctrl/pinctrl-rockchip-pinctrl/pinmux-pins查看管脚复用情况看起来是正常的：

pin 145 (gpio4-17): fe010000.ethernet (GPIO UNCLAIMED) function gmac1 group gmac1m1-clkinout

请处理过同样问题的朋友指点一下，谢谢。
