S3C6410(arm11核)的DM9000移植
第一步 配置内核 [*] Networking support ---> Networkingoptions ---> [*]TCP/IP networkingDevice Drivers ---> [*]Network device support ---> [*] Ethernet (10 or 100Mbit) ---> <*> DM9000 support 第二步 配置参数（1）#include <linux/dm9000.h>// ANW6410_PA_DM9000根据电路图中使用的片选决定#define ANW6410_PA_DM9000 (0x18000000)static struct resourceanw6410_dm9000_resource[] = { [0]= { .start= ANW6410_PA_DM9000, .end = ANW6410_PA_DM9000 + 3, .flags= IORESOURCE_MEM, }, [1]= { .start= ANW6410_PA_DM9000 + 4, .end = ANW6410_PA_DM9000 + 4 + 500, .flags= IORESOURCE_MEM, }, [2]= { .start= IRQ_EINT(7), .end = IRQ_EINT(7), .flags= IORESOURCE_IRQ | IRQF_TRIGGER_HIGH, },}; static struct dm9000_plat_dataanw6410_dm9000_pdata = { .flags =(DM9000_PLATF_16BITONLY | DM9000_PLATF_NO_EEPROM), /*dev_addr can be set to provide hwaddr. */}; static struct platform_deviceanw6410_device_eth = { .name = "dm9000", .id = -1, .num_resources = ARRAY_SIZE(anw6410_dm9000_resource), .resource = anw6410_dm9000_resource, .dev = { .platform_data = &anw6410_dm9000_pdata, },}; 在anw6410_machine_init中调用anw6410_dm9000_enable();（4）static struct platform_device*anw6410_devices[] __initdata = { &s3c_device_fb, &anw6410_lcd_powerdev, &anw6410_device_eth, &s3c_device_nand,}; 移植中遇到的问题：1.移植dm9000开发板ping电脑时，系统死掉，提示以下错误[root@FriendlyARM /]# ping 192.168.1.89PING 192.168.1.89 (192.168.1.89): 56 data bytes------------[ cut here ]------------WARNING: at net/sched/sch_generic.c:246 dev_watchdog+0x15c/0x244()NETDEV WATCHDOG: eth0 (dm9000): transmit queue 0 timed outModules linked in:[<c0025868>] (unwind_backtrace+0x0/0xd4) from [<c0036f40>] (warn_slowpath_common+0x48/0x60)[<c0036f40>] (warn_slowpath_common+0x48/0x60) from [<c0036f90>] (warn_slowpath_fmt+0x24/0x30)原因已找到是和其它设备配置起冲突导致出现这个问题
