u-boot-2014.10移植识别dm9000

Posted 2021-01-17 hulig7

在smdk2440.h里面注释掉CS8900相关的

#if 0
        #define CONFIG_DRIVER_CS8900    1    /* we have a CS8900 on-board */
        #define CS8900_BASE        0x19000300
        #define CS8900_BUS16        1 /* the Linux driver does accesses as shorts */
        #endif
        
        #if !defined(CONFIG_DRIVER_CS8900)
        #define CONFIG_DRIVER_DM9000        1
        #define CONFIG_DM9000_USE_16BIT     1
        #define CONFIG_DM9000_BASE            0x20000000
        #define DM9000_IO                    0x20000000  
        #define DM9000_DATA                    0x20000004
        #endif

并修改默认IP配置

在什么smdk2440.c board_eth_init函数里面添加

#ifdef CONFIG_DRIVER_DM9000
    rc = dm9000_initialize(bis);
#endif

再次烧写，可以识别

Net:   dm9000

 

设置ip

#define CONFIG_NETMASK          255.255.255.0
#define CONFIG_IPADDR           192.168.1.111
#define CONFIG_SERVERIP         192.168.1.113
#define CONFIG_ETHADDR          00:0c:29:45:c4:c3 

后面可以使用nfs和tftp来下载u-boot， kernel 和rootfs
