添加rtl8019驱动后的问题
按照http://skyeye.wiki.sourceforge.net/uClinux#tocuClinux4中所述添加网卡驱动，在uClinux-dist/linux-2.4.x/driver/net中加入了Rtl8019.c和Rtl8019.h两个文件之后，修改uClinux-dist/linux-2.4.x/driver/net下的Makefile，修改为ifeq ($(CONFIG_ARCH_ACORN),y)
mod-subdirs += ../acorn/net
subdir-y += ../acorn/net
obj-y += ../acorn/net/acorn-net.o
obj-y += rtl8019.o（加入的内容）
endif
然后直接make menuconfig,make dep,make

Makefile修改后，是不是要在编译时选一些选项？
在uClinux下 ifconfig eth0 10.0.0.2和ifconfig eth0 up 10.0.0.2的输出结果不一样（结果如上） 提示的两个错误是什么呢？
我用的是uClinux-dist-20040408.tar和arm-elf-tools-20011219.tar
skyeye版本为1.2.6 从你的输出来看,没有 rt8019驱动加载的相关输出信息.所有有可能你的驱动没有被编译到内核中,你可以自己看一下内核的符号表中有没有rtl8019的相关函数,来确定是否编译rtl8019驱动到内核中。 顺便请教下ksh，
skyeye版本0.9.2
s3c44b0＋rtl8019＋ucos＋lwip的情况下，配置文件如下：
cpu: arm7tdmi
mach: s3c44b0

mem_bank: map=M, type=RW, addr=0x0c000000, size=0x00800000

mem_bank: map=I, type=RW, addr=0x08000000, size=0x00800000
mem_bank: map=I, type=RW, addr=0x0e000000, size=0x00800000
mem_bank: map=I, type=RW, addr=0x01c00000, size=0x00400000
net: state=on, mac=0:4:3:2:1:f, ethmod=tuntap, hostip=10.0.0.1
网卡的基址和中断号是多少?
uclinux驱动文件里有三种情况：
#ifdef CONFIG_ARCH_S3C44B0X
#ifdef RTL8019_OP_16
#define BaseAddr 0x6000000
#elif defined(RTL8019_OP_8_EXTRA)
#define BaseAddr 0x3000000
#else /* RTL8019_OP_8 */
#define BaseAddr 0x8000000
#endif
#define IRQ_NUM 22
#else /* for AT91 or others */
#define BaseAddr 0xfffa0000
#define IRQ_NUM 16
#endif
我尝试在初始化网卡的函数ne2k_init里打印mac地址，结果不是预期的0:4:3:2:1:f。另外也尝试在初始化网卡后do_irq函数里打印中断号，结果没有来自网卡的中断。。。
我是用ucosii4skyeye里适合at91的ucos+lwip的代码，再加上s3c44b0的启动代码，ucos能够运行。添加lwip的代码之后，只是修改了网卡的基址。
回复 2# ksh 的帖子
和obj-y += rtl8019.o（加入的内容）这一句添加的位置有没有关系呢？？
