在drivers/net/ethernet/allwinner/sunxi-gmac.c 中 geth_phy_init函数中 phy_connect_direct 之前加入phy_write(phydev, 0x0, 0x2100)。以上是我们在A40i开发过程中常见网卡设计问题，有些可能是因为大家在参考方案时出现了配置问题，或者是因为芯片输出的信号不正常导致。大家在参考飞凌A40i的双网口方案时，可以...

我正尝试在我的定制板上运行marvellphylinux驱动程序。驱动程序使用的是mdio接口,但我的主板上有i2c。我将marvell.c文件中的phy_read()/phy_write()替换为i2c读/写函数。它不起作用。未调用探测函数,phy子系统使用mdio检测marvell,无法检测。如何在phylinuxsysbsystem中使用i2c?
