开发板:OK6410-A uboot版本:uboot1.16
一、修改include/configs/smdk6410.h里配置网卡的相应代码
原来:// #define CONFIG_DRIVER_SMC911X1 /* we have a SMC9115 on-board */
//#define CONFIG_CH7033
#ifdef CONFIG_DRIVER_SMC911X
#undef CONFIG_DRIVER_CS8900
#define CONFIG_DRIVER_SMC911X_BASE 0x18800300
#else
#define CONFIG_DRIVER_CS89000 /* we have a CS8900 on-board */
#define CS8900_BASE 0x18800300
#define CS8900_BUS16 1 /* the Linux driver does accesses as shorts */
#endif替换为:
#define CONFIG_DRIVER_DM9000AE1
#ifdef CONFIG_DRIVER_DM9000AE
#define CONFIG_DRIVER_DM90001
#define CONFIG_DM9000_BASE(0x18000000) /*XM0CSN1*/
#define DM9000_IO(CONFIG_DM9000_BASE)
#define DM9000_DATA(CONFIG_DM9000_BASE+0x4) /*ADDR2*/
#define CONFIG_DM9000_USE_16BIT 1
//#define CONFIG_DM9000_DEBUG 1
#else
#ifdef CONFIG_DRIVER_SMC911X
#undef CONFIG_DRIVER_CS8900
#define CONFIG_DRIVER_SMC911X_BASE 0x18800300
#else
#define CONFIG_DRIVER_CS89000 /* we have a CS8900 on-board */
#define CS8900_BASE0x18800300
#define CS8900_BUS161 /* the Linux driver does accesses as shorts */
#endif //end of #ifdef CONFIG_DRIVER_SMC911X
#endif //end of #ifdef CONFIG_DRIVER_DM9000AE
另外按实际修改或添加网络配置信息:
#define CONFIG_ETHADDR00:40:5c:26:0a:5b
#define CONFIG_NETMASK255.255.255.0
#define CONFIG_IPADDR192.168.0.110
#define CONFIG_SERVERIP192.168.0.101
#define CONFIG_GATEWAYIP192.168.0.1
二、修改 uboot1.16/board/samsung/smdk6410/smdk6410.c (可选做)
将 SC8900 替换为 DM9000 。
将 sc8900 替换为 dm9000 。
三、修改 drivers/dm9000x.c
int eth_init(bd_t * bd)函数:
1)
/* GPIO0 on pre-activate PHY */
DM9000_iow(DM9000_GPR, 0x00); /*REG_1F bit0 activate phyxcer */
//==============添加以下===============//
#if CONFIG_DRIVER_DM9000AE
udelay(100*1000); /* wait >2 ms (2~60 ms normal) for PHY power-up ready */
/* software-RESET NIC */
DM9000_iow(0x00,0x3); /* NCR REG. 00 RST Bit[0]=1 RESET on, LBK=1 MAC loopback on */
udelay(1000); /* wait >10us for software-RESET ok, then let it auto-clear */
#endif
//==============添加以上=============//
/* Set PHY */
set_PHY_mode();
2)
DM9000_iow(DM9000_ISR, 0x0f); /* Clear interrupt status */
/* Set Node address */
//==============添加以下===============//
if (is_zero_ether_addr(bd->bi_enetaddr) ||
is_multicast_ether_addr(bd->bi_enetaddr))
{
/* try reading from environment */
u8 i;
char *s, *e;
s = getenv ("ethaddr");
for (i = 0; i < 6; ++i)
{
bd->bi_enetaddr[i] = s ? simple_strtoul (s, &e, 16) : 0;
if (s)
s = (*e) ? e + 1 : e;
}
}
//==============添加以上=============//
3)
for (i = 0, oft = 0x16; i < 8; i++, oft++)
//修改MAR寄存器(Multicast Address Register)的值,修正第一次收不到数据的错误
//DM9000_iow(oft, 0xff); //替换
DM9000_iow(oft, 0x00) ;
void eth_halt(void)函数: (可选做)
注释掉下面两行,修正一直无法收到数据的错误
phy_write(0, 0x8000); /* PHY RESET */
DM9000_iow(DM9000_GPR, 0x01);/* Power-Down PHY */
