在SkyEye模拟Lubbock开发板的过程

goldenarms

楼主能不能告诉我在那里可以下SkyEye的LCD和触摸屏补丁（for lubbock）？多谢。

新版本的SkyEye应该支持LCD和触摸屏了，问问chyyu版主吧。

呵呵,是编译工具的库不行,俺换了个3.2.3的(原来是3.3.2),就可以了.

谢谢你!

bucketxp,你在SKYEYE上insmod过PXA255的驱动模块吗?是自己后加的设备,不是lubbock自己的设备,我在insmod的时候总是提示no valid format,无法加载,郁闷!

自己编译个文件
// hello.c
#define MODULE
#include <module.h>

int init_module( void )
{ printk("1\n"); return 0; }

void cleanup_module( void )
{ printk("2\n"); }

/usr/local/arm/3.2.3/bin/arm-linux-gcc -c hello.c -DMODULE -D__KERNEL__ -I/usr/local/arm/arm-linux/sys-include/asm-arm/

编译是通过了,但是加载就不行.bucketxp帮帮忙吧.

是啊，我也遇到这个问题了。我觉得可能与内核版本有关吧。
SkyEye模拟的Lubbock运行的是2.6.7的内核，而你在编译的模块的的时候所用的工具链相应的内核版本应该不是2.6.7的吧。
我觉得编译应用程序用那个工具都没有问题，只要有相应的动态库就行了。不过要编译动态加载的内核模块，工具链是不是应该和内核配套呢？这部分我也不是很清楚。

模块的问题你解决了吗？

在x86下写过一个这种简单的模块，2.6.x内核的驱动程序好像没这么简单，按照以前老的写法（2.4内核的写法）加载的时候就是这个错误。我记得编译的时候还要有个特殊的步骤，现在想不起来了，哪位清楚地说说看

zengnan

2.6.x的内核编译模块是先用gcc编出.o
然后
(1)scripts/modpost -o /usr/src/linux-2.6.5-1.358/Module.symvers vmlinux sound/oss/btaudio.o sound/soundcore.o
(2)ld -m elf_i386 -r -o sound/soundcore.ko sound/soundcore.o sound/soundcore.mod.o
最后生成的这个ko文件是用来insmod的模块
如果把modpost用arm-linux-gcc编译, 再把ld换成arm-linux-ld行不行

[quote:0c0db958dc="cuinantrue"]johmson80说的是!我按照楼主说的写了,但是无法执行那些脚本,不知是何缘故?[/quote]

是你的脚本没有加可执行权限吧

bucketxp兄弟,知道怎么能把KERNEL2.4.5移植到LUBBOCK上吗?
