Kernel compilation

Preparation before compilation

  • Create a compile working directory 
=====> Input:
mkdir ~/my-work/02_source/ -p
  • Unpack source code to working directory
=====> Input:

Target File

zImage、myimx6ek*.dtb 和 kernel-modules.tar.bz2 is the target file compiled and the three 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 the target file

=====> Input:
$CC 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:

Linux QT5 program compilation

Prepare source code

　　Open the disk to 5_MY-Demo，Download MY-Linux-QT5-Demo-AboutUs-svn*.tar.bz2 file and copy to virtual machine.

  • Unzip the source package to the working directory
=====> Input:
tar xf MY-Linux-QT5-Demo-AboutUs-svn*.tar.bz2 -C ~/my-work/02_source/

QT Program compilation

  • Enter source directory 
=====> Input:
cd ~/my-work/02_source/AboutUs/
  • Generate Makefile file
=====> Input:
qmake

【Note】: If there is information that the 'qamke' command is not found because the configuration of the cross-compilation tool chain is not effective, you can perform this step after pressing the "source tool chain configuration file" operation in the previous "cross compilation tool chain installation"

  • Compile the target file
 
=====> Input:
make

=====> Output:

Run on MI-IMX6-A9 device

  • Copy the compiled AboutUs to the development board
  • Run QT5 target program on development board 
=====> Input:
chmod +x ./AboutUs
./AboutUs -platform eglfs

Run on the my-imx6-a7 device

  • Copy the compiled AboutUs to the development board
  • Run QT5 target program on development board 
=====> Input:
export DISPLAY=:0.0
chmod +x AboutUs
./AboutUs

Running results

You can see that the MYZR logo and some information are output on the development board display.
