mii命令是操作mii接口的命令,mii接口用来连接soc中的MAC控制器和外部的PHY芯片。 MAC与PHY参考链接:https://www.cnblogs.com/try-again/p/9179103.html mii命令主要是通过mii接口中的MDIO来读写phy芯片的寄存器 针对DP83867芯片 mii info //查看mii信息 mii write 0x0c 0x00 0x2100 //设置phy芯片为百兆,0x0...

但是当进入u-boot控制台并执行mdio read时，示波器在MDIO引脚上没有信号。附上日志和eth.c。请帮助找到...

第1条命令相当于make distclean,目的是清除工程,一般在第一次编译的时候最好清理一下工程。 第2条指令相当于make mx6ull_14x14_evk_emmc_defconfig,用于配置 uboot,配置文件为 mx6ull_14x14_evk_emmc_defconfig。 第3条指令相当于make -j8,也就是使用8核来编译uboot。
