uClinux-dist-20040408 skyeye 模擬

02-28

一、環境信息

宿主機 ：Ubuntu 16.04

源碼：uClinux-dist-20040408.tar.gz

交叉編譯工具：arm-elf-tools-20040427.sh

skyeye ：skyeye-1.2.5

二、編譯配置 uClinux

解壓 uClinux-dist-20040408.tar.gz 並進入 uClinux-dist 目錄，命令行下輸入

make xconfig

vendor/product selection 選擇 GDB ARMulator

kernel/library/defaults delection 選擇 linux-2.4.x uClibc 其它默認

輸入

make depmake

彈出錯誤，錯誤信息如下

Makefile:251: *** mixed implicit and normal rules: deprecated syntaxmake ARCH=armnommu CROSS_COMPILE=arm-elf- -C linux-2.4.x || exit 1make[1]: Entering directory /home/song/workspace/uClinux-dist/linux-2.4.xmake[1]: arm-elf-gcc：命令未找到unset GCC_EXEC_PREFIX; gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -o scripts/split-include scripts/split-include.cscripts/split-include.c: In function 『main』:scripts/split-include.c:133:6: warning: ignoring return value of 『fgets』, declared with attribute warn_unused_result [-Wunused-result] fgets(old_line, buffer_size, fp_target); ^scripts/split-include include/linux/autoconf.h include/configarm-elf-gcc -D__KERNEL__ -I/home/song/workspace/uClinux-dist/linux-2.4.x/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fno-common -pipe -fno-builtin -D__linux__ -g -DNO_MM -mapcs-32 -march=armv4 -mtune=arm7tdmi -mshort-load-bytes -msoft-float -DKBUILD_BASENAME=main -c -o init/main.o init/main.cmake[1]: arm-elf-gcc：命令未找到Makefile:420: recipe for target init/main.o failedmake[1]: *** [init/main.o] Error 127make[1]: Leaving directory /home/song/workspace/uClinux-dist/linux-2.4.xMakefile:252: recipe for target linux failedmake: *** [linux] Error 1

打開 uClinux-dist 目錄下的 makefile 找到 251 行，原來是舊版本的make 規則，新版本不支持，

這是原來的

linux linux%_only: @if [ $(LINUXDIR) != linux-2.5.x -a $(LINUXDIR) != linux-2.6.x -a ! -f $(LINUXDIR)/.depend ] ; then echo "ERROR: you need to do a make dep first" ; exit 1 ; fi $(MAKEARCH_KERNEL) -C $(LINUXDIR) $(LINUXTARGET) || exit 1 if [ -f $(LINUXDIR)/vmlinux ]; then ln -f $(LINUXDIR)/vmlinux $(LINUXDIR)/linux ; fi

這是更改之後的

linux: @if [ $(LINUXDIR) != linux-2.5.x -a $(LINUXDIR) != linux-2.6.x -a ! -f $(LINUXDIR)/.depend ] ; then echo "ERROR: you need to do a make dep first" ; exit 1 ; fi $(MAKEARCH_KERNEL) -C $(LINUXDIR) $(LINUXTARGET) || exit 1 if [ -f $(LINUXDIR)/vmlinux ]; then ln -f $(LINUXDIR)/vmlinux $(LINUXDIR)/linux ; fi%_only: @if [ $(LINUXDIR) != linux-2.5.x -a $(LINUXDIR) != linux-2.6.x -a ! -f $(LINUXDIR)/.depend ] ; then echo "ERROR: you need to do a make dep first" ; exit 1 ; fi $(MAKEARCH_KERNEL) -C $(LINUXDIR) $(LINUXTARGET) || exit 1 if [ -f $(LINUXDIR)/vmlinux ]; then ln -f $(LINUXDIR)/vmlinux $(LINUXDIR)/linux ; fi

再次輸入 make ，又出現錯誤

make ARCH=armnommu CROSS_COMPILE=arm-elf- -C linux-2.4.x || exit 1make[1]: Entering directory /home/song/workspace/uClinux-dist/linux-2.4.xmake[1]: arm-elf-gcc：命令未找到arm-elf-gcc -D__KERNEL__ -I/home/song/workspace/uClinux-dist/linux-2.4.x/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fno-common -pipe -fno-builtin -D__linux__ -g -DNO_MM -mapcs-32 -march=armv4 -mtune=arm7tdmi -mshort-load-bytes -msoft-float -DKBUILD_BASENAME=main -c -o init/main.o init/main.cmake[1]: arm-elf-gcc：命令未找到Makefile:420: recipe for target init/main.o failedmake[1]: *** [init/main.o] Error 127make[1]: Leaving directory /home/song/workspace/uClinux-dist/linux-2.4.xMakefile:253: recipe for target linux failedmake: *** [linux] Error 1

但是我們確實已經裝上 arm-elf- 交叉編譯工具了啊，為什麼提示找不到？

這次是一個八竿子打不著的原因，經常在ubuntu 64位下運行 ./xxx 會跳出來說沒有這個文件或者目錄，但是ls看又有這個文件，很是奇怪。

其實原因很簡單，是因為他沒有32位的運行庫

輸入 apt-get install lib32ncurses5 lib32z1 安裝上就好了

在輸入 arm-elf-gcc -v

song@song:~/workspace$ arm-elf-gcc -vReading specs from /usr/local/lib/gcc-lib/arm-elf/2.95.3/specsgcc version 2.95.3 20010315 (release)(ColdFire patches - 20010318 from http://fiddes.net/coldfire/)(uClinux XIP and shared lib patches from http://www.snapgear.com/)

出現正確信息

再次，輸入 make，等待一會，又出現一個錯誤，唉問題就是這麼多，慢慢找，

原來是沒有清理

試著輸入

make clean make distclean

就好了成功信息是，

uClinux-dist/images 目錄下是生成的文件.

三、skyeye模擬

下面開始安裝 skyeye 命令行下輸入，

sudo apt-get install skyeye

不用配置和編譯，一個完整的skyeye就能用了，在uClinux-dist目錄下新建一個skyeye的配置文件 skyeye.conf，輸入以下內容。

cpu:arm7tdmimach:at91mem_bank:map=M, type=RW, addr=0x00000000, size=0x00004000mem_bank:map=M, type=RW, addr=0x01000000, size=0x00400000mem_bank:map=M, type=R, addr=0x01400000 , size=0x00400000, file=images/romfs.imgmem_bank:map=M, type=RW, addr=0x02000000, size=0x00400000mem_bank:map=M, type=RW, addr=0x02400000, size=0x00008000mem_bank:map=M, type=RW, addr=0x04000000, size=0x00400000mem_bank:map=I, type=RW, addr=0xf0000000, size=0x10000000

保存後在命令行輸入

skyeye -e linux-2.4.x/linux

按下回車，uclinux就開始運行了。

四、添加屬於自己的程序

下面介紹如何添加自己的用戶程序。

新建一個 hello.c

輸入

#include <stdio.h> int main() { printf("songwenshuai uclinux! "); return(0);}

命令行下輸入

arm-elf-gcc -Wall -elf2flt -o hello hello.c

此時會在目錄下生成名為 hello的二進位文件，把它複製到 romfs/bin 下

在命令行下輸入

genromfs -v -V "ROMdisk" -f ./images/romfs.img -d ./romfsmake imagemake

這樣我們的用戶程序就加進文件系統了，輸入

skyeye -e linux-2.4.x/linux

開機後輸入hello 就會列印自己程序的信息了。

songwenshuai uclinux! 就是我們自己添加的程序。
