pxa250 linux

snowman2008

请问为什么uClinux内核里没有pxa250啊?
是不是不能用uClinux?

ksh

use linux in kernel.org

谢谢了,我知道了,编译内核下载到skyeye中时总是出现这样的错误,
start addr is set to oxooo8000 by exec file

这是怎么回事那?

ksh

Refer to http://skyeye.wiki.sourceforge.net/Linux#tocLinux0

谢谢提醒，我就是按照上面做的，用的testsuit里的文件，只是增加了自己的vmlinux文件，但是运行testsuit就可以成功，但是运行自己的就不行了？不知道在编译内核的时候要注意什么？还有能不能详细的介绍一下你们pxa255的内核制作过程，不胜 感激！！

ksh

I had successfully run pxa255 on SkyEye according that document.So I think probably you missed something. You can describe your whole procedure more detailed include linux version and build procedure.

There  is  a  error  like the following,
Why?
and
What should I do to correct it?
When I use the vmlinux in testsuit, it is OK,
but when I run the linux compiled by me
there is a error.
I think it may be in the linux config,but I don't know
where I should change.
Would you like to tell me?

I use
Redhat Linux 2.4 environment,
arm-linux-tools-20061213.tar.gz
Linux 2.6.23 and Linux 2.6.20 kernel

Then
1 export ARCH=arm
2 export CROSSCOMPILE=arm-linux-
3 modify [include/asm-arm/arch-pxa/memory.h:42]
> #define PHYS_OFFSET UL(0xa0000000)
> to
> #define PHYS_OFFSET UL(0xc0000000)
4 make lubbock_defconfig
5 make menuconfig
modify:root/dev/ram  rw  initrd＝0x08000000,0x00800000 console=ttyS0 mem=64M

--->修改
[ ]RamDisk support
为

RamDisk support
--->修改
(4096) Default Ram disk size(kbytes)
为
(8192) Default Ram disk size(kbytes)
--->修改
[ ] Initial Ram disk (initrd) support
为

Initial Ram disk (initrd) support

Then make zImage

There is no error in compile.

Then
use init.img and skyeye.conf in testsuit
then

skyeye -e vmlinux
