回复 #15 gbf0871 的帖子
thanks for your tips.the related content in the file is:
/* add for skyeye */
#include <asm-arm/arch-s3c2410/smdk2410.h>
#include "devs.h"
#include "cpu.h"
static struct map_desc smdk2410_iodesc[] __initdata = {
/* nothing here yet */
/* add for skyeye */
/* Map the ethernet controller CS8900A */
{vSMDK2410_ETH_IO,pSMDK2410_ETH_IO, SZ_1M, MT_DEVICE}
/* add for skyeye end */
};
I think it is the same with zbluecn's

This problem is solved, in /include/asm-arm/arch-s3c2410/memory.horiginal text is :
/*
* DRAM starts at 0x30000000 for S3C2410/S3C2440
* and at 0x0C000000 for S3C2400
*/
#ifdef CONFIG_CPU_S3C2400
#define PHYS_OFFSET (0x0C000000UL)
#else
#define PHYS_OFFSET (0x30000000UL)
#endif
At the first time, i modify it as:
#ifdef CONFIG_CPU_S3C2400
#define PHYS_OFFSET (0x0C000000UL)
#else
#define PHYS_OFFSET (0xC0000000UL)
#endif
so the error is occur.
The right modification is :
#ifdef CONFIG_CPU_S3C2400
#define PHYS_OFFSET (0xC0000000UL) /* notify here */
#else
#define PHYS_OFFSET (0xC0000000UL)
#endif

如果你要使用zImage就不要使用这个修改了不过 使用zImage,在skyeye上模拟, 解压的速度很慢~~ 不知道是不是我的机子的问题

10、配置、编译内核。在内核顶层目录当中键入：#make smdk2410_defconfig --------->modify as: #make s3c2410_defconfig
由于2.6的内核默认就支持了S3C2410，所以就有一个默认的内核配置文件。里面只是包
括了一个简单的配置，要使网卡编译进内核，还要进行手工配置。

你没有挂机根目录~~ skyeye-testsuite-2.3/linux/s3c2410/s3c2410x-2.6.14 的网卡是不能使用的需要自己加入cs8900的驱动啊 还有打skyeye 1.2.4 的补丁了吗
回复 #23 zbluecn 的帖子
i had patched the dev_net_cs8900.diff for skyeye, also involved cs8900 driver for linux.Now the target and host can communicate with each other, but i do nothing with it.
I guess skyeye's driver is not stable, sometimes it works, and sometimes it rests.
a little disappointing.
BTW: when install fedora, i select the English language. now i can not use any Chinese except copy and paste. any solution? 您好：我对第10步的
#make menuconfig
根目录文件使用skyeye-testsuite-2.3.tar.bz2 中s3c2410的镜像
设置内核启动参数mem=32M console=ttySAC0 root=/dev/ram initrd=0xc0800000,0x00800000 ramdisk_size=2048 rw
我的理解是把skyeye-testsuite-2.3/linux/s3c2410/s3c2410x-2.6.14/目录下的skyeye.conf文件拷贝到linux-2.6.14目录下，并接将lcd那行注释掉。
但是在运行skyeye -e vmlinux时，在图示部位停止执行
难道要用skyeye-testsuite-2.3/linux/s3c2410/s3c2410x-2.6.14/目录下的vmlinux覆盖make生成的vmlinux吗？谢谢！
（skyeye-testsuite-2.3/linux/s3c2410/s3c2410x-2.6.14/下的vmlinux测试过，好使） "根目录文件使用skyeye-testsuite-2.3.tar.bz2 中s3c2410的镜像
",应该是复制 initrd吧
回复 #26 lvcoffee 的帖子
对 我少说了 两个都复制了啊。。。 skyeye.conf和initrd.img文件上面的问题已经解决 谢谢高手们的指点！
现在执行到“Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)”又停止了。。。
看LZ发的图片 不是执行skyeye -e vmlinux之后再mkdir mnt；mount -o nolock 10.0.0.1:root/arm mnt的吗？
还有就是 “root/arm ”具体是指哪个目录，里面有什么？
谢谢！

您好，我遇到和您一样的错误，请问您是怎么挂载的啊？ 谢谢！求救！谢谢！
楼上各位兄弟，我按照楼主的步骤，编译出来了vmlinux, 我把它拷贝到拷贝到testsuit 2.3里边的s3c2410x-2.6.14目录里，skyeye -e vmlinux
启动内核的时候就定在那里了，不知道是啥原因，在楼主的文章里，有一个地方不是很明白：就是内核参数，我是修改的.config文件里的CONFIG_CMDLINE, 不知道对不对。
我看楼上有的兄弟没有运行起来，是缺了文件了，我把vmlinux复制到s3c2410x-2.6.14这个文件夹，应该不缺什么了呀，
是不是还有什么需要改动的地方，请大家说说呀，初学，头疼！

设置内核启动参数mem=32M console=ttySAC0 root=/dev/ram initrd=0xc0800000,0x00800000 ramdisk_size=2048 rw这个步骤具体怎么操作？？
