移植PXA255的一些问题

ssancel

在skyeye上移植linux-2.6.9(开发板配的，有改动过的）
文件系统使用jffs2.
出错如下：
Hit any key to stop autoboot:  0
$ cp 00040000 a0200000 00200000
$ go a0200000
## Starting application at 0xA0200000 ...

skyeye.conf如下：
cpu: xscale
mach: pxa_lubbock

mem_bank: map=F, type=RW, addr=0x00000000, size=0x00040000, file=./u-boot.bin, boot=yes
mem_bank: map=F, type=RW, addr=0x00040000, size=0x00200000, file=./zImage
mem_bank: map=F, type=RW, addr=0x00240000, size=0x01dc0000, file=./lubbock_rootfs.jffs2

#mem_bank: map=F, type=RW, addr=0x04000000, size=0x02000000

mem_bank: map=I, type=RW, addr=0x40000000, size=0x0c000000

mem_bank: map=M, type=RW, addr=0xa0000000, size=0x04000000

jffs2制作命令：./mkfs.jffs2 -r lubbock_rootfs/ -o lubbock_rootfs.jffs2 -e 0x40000 --pad=0x01dc0000

请问这个错误是什么原因产生的？是skyeye.conf 没写好吗？还是文件系统跟内核没有匹配呢？怎么改正呢？

近来想做LINUX移植，目标板是PXA255的LUBBOCK板上，所以先到网上下skyeye-binary-testutils-1.2.0这套工具下来。lubbock_with_flash这个目录下的东西跟我的目标板比较接近。按作者的README文件 的作法一点问题也没有，但把内核换成板子自带的就出现了上术的问题。

ksh

可以尝试一下使用RAMDISK做为文件系统
