将DM9000编译进u-boot，在Makefile (u-boot-2016.05\drivers\net) 中添加
obj-$(CONFIG_DRIVER_DM9000) += dm9000x.o
同时，在Smdk2440.h (u-boot-2016.05\include\configs)中定义CONFIG_DRIVER_DM9000，同时屏蔽掉CS8900相关信息。
/* * Hardware drivers */ #define CONFIG_DRIVER_DM9000 //#define CONFIG_CS8900 /* we have a CS8900 on-board */ //#define CONFIG_CS8900_BASE 0x19000300 //#define CONFIG_CS8900_BUS16 /* the Linux driver does accesses as shorts */
编译，出现BUG“DM9000_DATA ” is not define，仿照At91sam9260ek.h (u-boot-2016.05\include\configs)DM9000的相关配置，在Smdk2440.h (u-boot-2016.05\include\configs)配置
/* * Hardware drivers */ #define CONFIG_DRIVER_DM9000 #define CONFIG_DM9000_BASE 0x20000000 #define DM9000_IO CONFIG_DM9000_BASE #define DM9000_DATA (CONFIG_DM9000_BASE + 0x4)
