「Android」ZTE V880(Blade)内核编译过程实录

 

由于之前手机是双卡的，不好研究，现在弄到一台中兴V880，今天早上来编译内核一下～

-1. Blade Kernel 2.6.35.7 Download page

Github ：https://github.com/TomGiordano/kernel_zte_blade

官方网站：http://support.zte.com.cn/support/news/NewsDetail.aspx?newsId=1001722

0. 前边的步骤略过一下先，不过也写有在U8825D内核编译过程实录当中有记录，最主要的是export变量的配置上

1. 查找官方内核中的配置文件

scue@Link:~/Source/kernel/v880$ find ./arch/arm/configs/ | grep blade

./arch/arm/configs/msm7627_blade_defconfig

scue@Link:~/Source/kernel/v880$ 

　可以确定为配置文件为./arch/arm/configs/msm7627_blade_defconfig

2. 开始make 配置文件 

scue@Link:~/Source/kernel/v880$ make msm7627_blade_defconfig

  HOSTCC  scripts/basic/fixdep

  HOSTCC  scripts/basic/docproc

  HOSTCC  scripts/basic/hash

  HOSTCC  scripts/kconfig/conf.o

scripts/kconfig/conf.c: 在函数‘conf_sym’中:

scripts/kconfig/conf.c:159:6: 警告： 变量‘type’被设定但未被使用 [-Wunused-but-set-variable]

scripts/kconfig/conf.c: 在函数‘conf_choice’中:

scripts/kconfig/conf.c:231:6: 警告： 变量‘type’被设定但未被使用 [-Wunused-but-set-variable]

scripts/kconfig/conf.c:307:9: 警告： 忽略声明有 warn_unused_result 属性的‘fgets’的返回值 [-Wunused-result]

scripts/kconfig/conf.c: 在函数‘conf_askvalue’中:

scripts/kconfig/conf.c:105:8: 警告： 忽略声明有 warn_unused_result 属性的‘fgets’的返回值 [-Wunused-result]

  HOSTCC  scripts/kconfig/kxgettext.o

  SHIPPED scripts/kconfig/zconf.tab.c

  SHIPPED scripts/kconfig/lex.zconf.c

  SHIPPED scripts/kconfig/zconf.hash.c

  HOSTCC  scripts/kconfig/zconf.tab.o

  HOSTLD  scripts/kconfig/conf

drivers/usb/gadget/Kconfig:849:warning: defaults for choice values not supported

drivers/usb/gadget/Kconfig:1053:warning: defaults for choice values not supported

arch/arm/configs/msm7627_blade_defconfig:1484:warning: override: reassigning to symbol OV5642

#

# configuration written to .config

#

scue@Link:~/Source/kernel/v880$ 

　make完毕，有一些警告，但不是错误，可以不理会它（暂时也没空去分析、要上课了）

3. 开始编译V880手机内核

scue@Link:~/Source/kernel/v880$ make -j8

    ...   

    OBJCOPY arch/arm/boot/zImage

    Kernel: arch/arm/boot/zImage is ready

scue@Link:/media/scue/Source/kernel/zte-kernel-blade$ cp arch/arm/boot/zImage http://www.cnblogs.com/v880-bootimg/zImagescue

4. 解包现有的手机内核

scue@Link:/media/scue/Source/v880-bootimg$ bootimg --unpack-bootimg v880_boot.img

arguments: [bootimg file]

bootimg file: v880_boot.img

output: kernel[.gz] ramdisk[.gz] second[.gz]

base=0x2600000

page_size=2048

name=""

cmdline="androidboot.hardware=blade console=null"

padding_size=2048

5. 打包V880手机内核

　(方法一，mkbootimg打包)

scue@Link:/media/scue/Source/v880-bootimg$ ls -l

注：不过有一点遗憾就是，替换了内核之后，手机没有能够识别SIM卡，准备要家教去了，这个事情以后再处理～
　　不过现在这个问题已经解决了，解决时间：2012年 11月 12日 星期一 18:44:42 HKT
