skyeye xscale 仿真错误 (again)
之前，已经有一篇关于xscale的运行贴子http://www.linuxfans.org/nuke/modules.php?name=Forums&file=viewtopic&t=70084&start=0&postdays=0&postorder=asc&highlight=
但这里再次问一下，不同之处：
（1）错误现象不同
（2）上篇chyyuu的解决方法还不太理解：
前言：
（1）我安装的是skyeye-0.7.4
（2）基于linux-2.4.19, patch-2.4.19-rm7, diff-2.4.19-rm7-pxa2编译内核（cd /usr/src/linux-2.4.19/; make lubbock_config; make dep zImage，一切都很顺利 ）
(Add-on: cross-tool is gcc-3.2.1 + binutils-2.13.90)
（3）skyeye.conf, initrd4M.img (来源：skyeye-binary-testsuit-1.0.7/xscale/linux-2.4.x), zImage (来源：/usr/src/linux-2.4.19/arch/arm/boot/zImage)
运行：
# skyeye

问题：
是否需要按上篇文章那样，修改config文件？ 你内核编译的时候，选了IDE了吧，skyeye还没有仿真IDE，你重新编译内核，去掉IDE的选项，在试一下。 谢谢，我试一下。
帮忙“诊断”一下！
依照上篇回复的提示，我开始做一个内核没有IDE设备搜索的。但做了几次都失败了，
$make config （很多选项不知道应该怎样设，这样反复了很多次）
$make
常见的情况是：
Uncompressing Linux.............................. done, booting the kernel.
然后就HALT了。
最后一次是这样做的（虽然也失败了）
$cd /usr/src/linux-2.4.19
$make lubbock_config
===========================(make modifications)================================
------(1) remove the IDE/SCSI/USB/SoundCard etc.
------(2) set Kernel cmd_line : mem=64M root=/dev/ram ramdisk=8192 ramdisk_start=0xc1000000 console=ttyS0,115200
$make
(about 20 min.s later)
# cp /usr/src/linux-2.4.19/arch/arm/boot/zImage .
cp：是否覆盖‘./zImage’? y

比较以前有进步：
（1）原先解压缩完之后，就HALT了；
（2）但root fs mount失败？？
（我用的initrd4M是从网上的skyeye-testutils-1.0.7/xscale/linux-2.4.x拷贝来的） 现在解决这个问题了吗？ 没有解决。这个实验暂停了。准备仔细做一遍armlinux的编译。另外，initrd4M.img的相关信息从那里能获得？（如有关目录/文件，文件系统类型、大小的） initrd4M.img是自己做的，你也可以仿照initrd4M.img的内容自己做一个文件系统。 谢谢，试验通过了。原因是：内核编译没有配ext2支持，二是选了FAT。
我也试验了img的制作（修改），明白了。
# cd xscale/
# cd linux-2.4.x/
# ls
initrd4M.imgskyeye.confzImagezImage.newzImage.orig
# mkdir /mnt/test
# mount -loop initrd4M.img /mnt/test
mount: initrd4M.img is not a block device (maybe try `-o loop'?)
# mount -o loop initrd4M.img /mnt/test
# cd /mnt/test
# ls
bindevetchomeliblost+foundmntproctmpusrvar
然后添加了交叉编译出来的执行程序放入/mnt/test/bin目录，然后umount，通了。谢谢
