u-boot编译
编译前的准备
- 创建编译工作目录
=====> Input: mkdir ~/my-work/02_source/ -p
- 解压源码包到工作目录
=====> Input: tar xf u-boot-2016.03-svn*.tar.bz2 -C ~/my-work/02_source/
编译u-boot目标文件
- 进入源码目录
=====> Input: cd ~/my-work/02_source/u-boot-2016.03
- 生成目标开发板的 .config 文件
=====> Input: make myimx6ek200-6q-1g_defconfig =====> Output: HOSTCC scripts/basic/fixdep HOSTCC scripts/kconfig/conf.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/zconf.lex.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf # # configuration written to .config #
- 执行编译
=====> Input: make =====> Output: scripts/kconfig/conf --silentoldconfig Kconfig CHK include/config.h UPD include/config.h GEN include/autoconf.mk GEN include/autoconf.mk.dep CHK include/config/uboot.release UPD include/config/uboot.release CHK include/generated/version_autogenerated.h ...... LD u-boot OBJCOPY u-boot-nodtb.bin OBJCOPY u-boot.srec SYM u-boot.sym COPY u-boot.bin CFGS board/myzr/myimx6/myimx6a9-6q-ddr3.cfg.cfgtmp MKIMAGE u-boot.imx
Note: 如果有提示 “cc1: error”，基本是交叉编译工具的配置没生效，可以按前面 “交叉编译工具链安装” 中的 “source 工具链配置文件” 操作一次后再执行此步骤。
- 目标文件改名
=====> Input: cp u-boot.imx uboot-myimx6ek200-6q-1g.imx
编译u-boot环境变量脚本
=====> Input: ./tools/mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "MYZR script" -d my_env_src/myimx6a9_3035_script.cmd my_env_script.scr =====> Output: Image Name: MYZR script Created: Tue Nov 6 17:24:27 2018 Image Type: ARM Linux Script (uncompressed) Data Size: 1900 Bytes = 1.86 kB = 0.00 MB Load Address: 00000000 Entry Point: 00000000 Contents: Image 0: 1892 Bytes = 1.85 kB = 0.00 MB
目标文件
uboot-myimx6ek200-6q-1g.imx 和 my_env_script.scr 即编译得到的目标文件，保存这两个文件
内核编译
编译前的准备
- 创建编译工作目录
=====> Input: mkdir ~/my-work/02_source/ -p

Note: 如果有“Can't find default configuration "arch/x86/configs” 的错误，是因为交叉编译工具链的配置没有生效，可以按前面 “交叉编译工具链安装” 中的 “source 工具链配置文件” 操作一次后再执行此步骤
- 编译内核目标文件
=====> Input: make zImage =====> Output: scripts/kconfig/conf --silentoldconfig Kconfig CHK include/linux/version.h UPD include/linux/version.h CHK include/generated/utsrelease.h UPD include/generated/utsrelease.h Generating include/generated/mach-types.h CC kernel/bounds.s ......

编译内核模块包
- 执行编译
=====> Input: make modules =====> Output: CHK include/linux/version.h CHK include/generated/utsrelease.h make[1]: “include/generated/mach-types.h”是最新的。 CALL scripts/checksyscalls.sh CC [M] fs/autofs4/init.o ...... LD [M] drivers/usb/gadget/g_serial.ko LD [M] fs/nls/nls_ascii.ko LD [M] fs/autofs4/autofs4.ko LD [M] fs/nls/nls_utf8.ko
- 创建内核模块的保存目录
=====> Input: mkdir modules
- 安装内核模块到指定目录
=====> Input: make modules_install INSTALL_MOD_PATH=./modules =====> Output: INSTALL crypto/tcrypt.ko INSTALL drivers/gpu/drm/drm.ko INSTALL drivers/gpu/drm/vivante/vivante.ko ...... INSTALL fs/autofs4/autofs4.ko INSTALL fs/nls/nls_ascii.ko INSTALL fs/nls/nls_utf8.ko DEPMOD 3.0.35-myimx6a9
- 打包内核模块文件
=====> Input: tar cjf kernel-modules-myimx6a9.tar.bz2 -C modules lib
目标文件
zImage-myimx6a9 和 kernel-modules-myimx6a9.tar.bz2 即编译得到的目标文件，保存这两个文件
