请支持: skyeye-1.2.4 + linux-2.6.14 simulate S3C2410
跟据论坛及其他地方上的资料, 我在编译kernel 2.6.14时总不能得到可以运行的vmlinux.编译相关软件:
cross-compile: arm-linux-gcc-3.4.1.tar.bz2
skyeye: skyeye-1.2.4_Rel.tar.gz + skyeye-testsuite-2.3.tar.bz2
kernel: linux-2.6.14.tar.bz2
simulate cpu: S3C2410
步骤:
1. modify "Makefile"
ARCH= arm
CROSS_COMPILE= /usr/local/arm/3.4.1/bin/arm-linux-
2. modify "linux-2.6.14/include/asm-arm/arch-s3c2410/map.h" line 175
#define S3C2410_CS6 (0x30000000)
to
#define S3C2410_CS6 (0xC0000000)
3. modify "linux-2.6.14/include/asm-arm/arch-s3c2410/memory.h" line 33
#define PHYS_OFFSET (0x30000000UL)
to
#define PHYS_OFFSET (0xC0000000UL)
4. run "make s3c2410_defconfig"
5. run "make menuconfig"
check off
--> --> --> "8250/16550 and compatible serial support"
6. make
get file vmlinux
7. 使用testsuite的 linux/s3c2410/s3c2410x-2.6.14 文件 initrd.imgskyeye.conf
skyeye -e vmlinux
+++++++++++++++
编译过程没有出错， 但在skyeye里总不能启动起来。
请问, 我使用的过程中那个步骤有错, 或是缺少什么操作, 请大家帮忙, 谢谢! 补充一下：
编译平台为: (Fedora) 2.6.23.1-42.fc8 参考http://www.linuxfans.org/bbs/thread-182384-1-2.html 的内核配置
估计是你内核配置问题。
skyeye启动不起来，是什么意思？现象是什么？
至少把出错信息给出来啊！！ error message
--------------------
NET: Registered protocol family 1
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
---------------------
I found reason:
#make menuconfig
--> --> "[] Initial RAM disk (initrd) support" check it on
insmod 失败
前些日子在 skyeye 上 porting 了 arm-linux，于是迫不及待的写了一个 module 试试，可很不幸，没有成功。小弟最近才搞 linux 的 module 技术，很多地方不是很懂，现将问题贴出，希望大家不吝赐教。skyeye(version 1.2.4) 的配置文件 skyeye.conf:
