u-boot Compile
Preparation before compilation
- Create the compile working directory
=====> Input: mkdir ~/my-work/02_source/ -p
- Unzip the source package to the working directory
=====> Input: tar xf u-boot-2016.03-svn*.tar.bz2 -C ~/my-work/02_source/
Compile the u-boot target file
- Source directory
=====> Input: cd ~/my-work/02_source/u-boot-2016.03
- Generate the.config file for the target development board
=====> 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 #
- Perform compilation
=====> 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: if you are prompted with "cc1: error", the configuration of the cross-compilation tool is not in effect. You can follow the "source toolchain configuration file" in the previous "cross-compilation toolchain installation" before performing this step.* *
- Rename target file
=====> Input: cp u-boot.imx uboot-myimx6ek200-6q-1g.imx
Compile the u-boot environment variable script
=====> 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

Kernel compilation
Preparation before compilation
- Create the compile working directory
=====> Input: mkdir ~/my-work/02_source/ -p

- Source directory
=====> Input: cd ~/my-work/02_source/linux-3.0.35
- Generate the.config file for the target platform
=====> Input: make myimx6a9_defconfig =====> Output: HOSTCC scripts/basic/fixdep HOSTCC scripts/kconfig/conf.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 # # configuration written to .config #
Note: If there is an error in "Can't find default configuration "arch/x86/configs, because the configuration of the cross-compilation tool chain is not in effect, you Can perform this step after the" source tool chain configuration file "operation in the previous" cross-compilation tool chain installation "
- Compile the kernel target file
=====> 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 ...... AS arch/arm/boot/compressed/piggy.gzip.o LD arch/arm/boot/compressed/vmlinux OBJCOPY arch/arm/boot/zImage Kernel: arch/arm/boot/zImage is ready
- Kernel target file renamed
=====> Input: cp arch/arm/boot/zImage zImage-myimx6a9
Compile the kernel module package
- Compiling
=====> Input: make modules =====> Output: CHK include/linux/version.h CHK include/generated/utsrelease.h make[1]: “include/generated/mach-types.h” It's the latest. 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
- Create the save directory for the kernel module
=====> Input: mkdir modules
- Install the kernel module to the specified directory
=====> 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
- Package the kernel module file
=====> Input: tar cjf kernel-modules-myimx6a9.tar.bz2 -C modules lib
Object file
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
