U-boot2016.05移植TQ2440之網卡移植

原創 句号君DoubleLee 2020-02-23 16:04

將DM9000編譯進u-boot，在Makefile (u-boot-2016.05\drivers\net) 中添加


obj-$(CONFIG_DRIVER_DM9000) += dm9000x.o








同時，在Smdk2440.h (u-boot-2016.05\include\configs)中定義CONFIG_DRIVER_DM9000，同時屏蔽掉CS8900相關信息。






/*
 * 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 */





編譯，出現BUG“DM9000_DATA ” is not define，仿照At91sam9260ek.h (u-boot-2016.05\include\configs)DM9000的相關配置，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)
