mkdir ~/my-work/02_source/ -p
  • Unpack source code to working directory 
=====> Input:
tar xf u-boot-2016.03-svn*.tar.bz2 -C ~/my-work/02_source/

Compile the u-boot target file

  • Enter source directory
=====> Input:
cd ~/my-work/02_source/u-boot-2016.03
  • Generate the target development board. config file
=====> Input:
make myimx6ek200-6q-1g_defconfig

Note: If there is a prompt “cc1: error”，usually the configuration of the cross-compilation tool does not work, you can perform this step after pressing the "source tool chain profile” operation in the previous "cross compile tool chain installation".

  • u-boot Target File u-boot.imx is the target file.

Compile U-boot environment variable scripts

=====> Input:
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "myzr bootscripts" -d board/myzr/bootscripts/myimx6a9_l3035_script.cmd my_environment.scr

=====> Output:

Created:      Wed Jan  2 09:39:38 2019
Image Type:   ARM Linux Script (uncompressed)
Data Size:    2090 Bytes = 2.04 kB = 0.00 MB
Load Address: 00000000
Entry Point:  00000000
Contents:
   Image 0: 2082 Bytes = 2.03 kB = 0.00 MB

Target File

"u-boot.imx " and " my_environment.scr" That is, the compiled target file, saving the two files


Kernel compilation

Preparation before compilation

  • Create a compile working directory 
=====> Input:
mkdir ~/my-work/02_source/ -p
  • Unzip the source package to the working directory 
=====> Input:
tar xf linux-3.0.35-svn*.tar.bz2 -C ~/my-work/02_source/

Compile the kernel target file

  • Enter source directory 
=====> Input:

#
# configuration written to .config
#

Note: If there is an error“Can't find default configuration "arch/x86/configs” ，because the configuration of the cross compilation tool chain did not work,You can do this step again after you have done it once in the "source toolchain configuration file" in "cross-compile toolchain installation earlier"

=====> Input:
mkdir modules
  • Install kernel module to 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/nls/nls_ascii.ko
  INSTALL fs/nls/nls_utf8.ko
  DEPMOD  3.0.35-myimx6a9-svn42
  • Package the kernel module files 
=====> Input:
tar cjf kernel-modules.tar.bz2 -C modules lib

Target File

"zImage" and "kernel-modules.tar.bz2" are the target files compiled and the two files are saved


Linux C program compilation

Prepare source code

　　Open the disk to 5_MY-Demo -> MY-Linux-C-Demo，Download hello.c file and copy to virtual machine.

Compile target file

=====> Input:
${CROSS_COMPILE}gcc hello.c -o hello.out

Note: If you have "no command found" information because the configuration of the cross-compilation tool chain is not effective, you can perform this step after pressing the "source tool chain profile" operation in the previous "cross compilation tool chain installation"

Run Linux C Target Program

  • Copy the compiled" hello.out" to the development board
  • Run the Linux C target program on the development board 
=====> Input:
chmod +x ./hello.out
./hello.out

=====> Output:
