的驱动.
可是在make的时候有如下错误:

难道,在head.S里没有正确跳转到start_kernel还是 printk()函数没有作用?????

请问为arm编译2.6内核大家都用什么版本的gcc编译器?为什么我用arm-linux-gcc.3.4.1时会出现cc1: error: invalid option `short-load-bytes'的错误,有网友建议这样改:
CFLAGS +=-mapcs-32 $(arch-y) $(tune-y) –mshort-load-bytes –msoft-float –Wa,-mno-fpu -Uarm
AFLAGS +=-mapcs-32 $(arch-y) $(tune-y) -msoft-float -Wa,-mno-fpu
        替换为:
                CFLAGS +=-mapcs-32 $(arch-y) $(tune-y) -malignment-traps -msoft-float
                  AFLAGS +=-mapcs-32 $(arch-y) $(tune-y) -msoft-float
这样改过之后编译确实通过了;但这样会不会造成什么功能损失?
也有网友说要用更高版本的gcc编译器,那么现在有什么版本的编译器可以解决这个问题?
期待各位高手教教小弟,感激不尽呀!

那时在printk函数中调用console_drivers->write失败。
我还在研究中。

粗体的使我添加的。但是串口没有打印我插入的打印文字.......
难道,在head.S里没有正确跳转到start_kernel还是 printk()函数没有作用?????

内核2.6.19,toolchain arm-linux-gcc-3.3.2, 使用ARM中的edb7211_defconfig这个默认的配制,我没有改动其中的设置。
结果出现了如下的错误,(按字面说好像是语法分析错误)请问怎么修正???

当用3.4.1来编译,就算加了括号,还是会有如下错误:
In file included from fs/jffs2/compr.h:26,
                 from fs/jffs2/compr.c:16:

'>'明明已经有左操作数的,怎么会报错呢?搞不懂。

现在手头只有s3c4510B的开发板,也不知道有没有这个板子的patch,
要移植的话要做不少工作吧?

uda1341驱动问题:

请教:
       我用surperlp的uda1341程序在linux2.6.14.1上运行,为什么最后linux的内核启动信息里面没有uda初始化成功的信息输出,使用命令查找sound设备:ls -al /dev/sound/* ,显示信息:no that file or directory,好像是设备还是驱动根本没有挂上pci总线,哪里出了问题阿?各位高手,给小菜鸟一点提示阿,急!
       谢谢!

U-BOOT可以使用setenv命令更改命令参数
setenv bootargs console=ttySAC0,115200

u-boot go命令不能传递命令行参数给内核,因此会在运行HEAD.S中检测CPU类型时错误而终止运行
另外,在U-BOOT配制文件(INCLUDE\CONFIGS\XXX.H)中需要定义下面宏,使能U-BOOT传递命令参数给内核
#define CONFIG_SETUP_MEMORY_TAGS
#define CONFIG_INITRD_TAG
#define CONFIG_CMDLINE_TAG

U-BOOT的BOOTM命令只能引导附加U-BOOT信息的内核,U-BOOT会在内核前加64个字节信息.
在U-BOOT目录下的TOOLS目录中有MKIMAGE工具制作U-BOOT能够引导内核
在U-BOOT README文件中有描述如下
引用:
Configuring the Linux kernel:
-----------------------------

No specific requirements for U-Boot. Make sure you have some root
device (initial ramdisk, NFS) for your target system.


Building a Linux Image:
-----------------------
...............
U-BOOT目录/tools/mkimage -A arm-O linux -T kernel -C none\
-a 30008000 -e 30008000  -n "Linux Kernel Image" -d zImage uImage
zImage 为LINUX压缩内核,这个在LINUX目录arch/arm/boot/makefile有介绍
引用:
quiet_cmd_uimage = UIMAGE  $@
      cmd_uimage = $(CONFIG_SHELL) $(MKIMAGE) -A arm -O linux -T kernel \
                   -C none -a $(ZRELADDR) -e $(ZRELADDR) \
                   -n 'Linux-$(KERNELRELEASE)' -d $< $@
由于U-BOOT在内核前添加64个字节,所以引导时应该考虑这个64个字节
