02-Buildroot_System_Customization

  1. Mount /dev/mmcblk0p1.

  2. Replace the bootlogo.bmp file.

Startup Programs

Disable Default QT Program Autostart:

# On the board:  
mv etc/init.d/S90deviceTest_QT etc/init.d/D90deviceTest_QT  

# SDK path:  
buildroot/config/buildroot/allwinner/system/busybox-init-base-files/etc/init.d/S90deviceTest_QT

Add Custom Startup Program:

  1. Create a script in /etc/init.d/ on the board.

  2. SDK reference path:

buildroot/config/buildroot/allwinner/system/busybox-init-base-files/etc/init.d/

Adding Applications

Buildroot does not support apt. Modify the SDK configuration to add or remove tools.

Add/Remove Tools via Buildroot:

  1. Open the graphical configuration:

./build.sh buildroot_menuconfig

  1. Save changes:

./build.sh buildroot_saveconfig

  1. Recompile:

./build.sh && ./build.sh pack

Common Issues: If changes do not take effect, run:

rm -rf out/t113/evb1_auto/buildroot/buildroot/target  
find out/t113/evb1_auto/buildroot/buildroot -name ".stamp_target_installed" | xargs rm -rf  
./build.sh lunch  
./build.sh && ./build.sh pack

Add User Applications or Tools:

Method 1: After a full SDK compilation, modify:

t113-linux/out/t113/evb1_auto/buildroot/buildroot/target

Repack and recompile.

Method 2: Modify the skeleton directory before compilation:

t113-linux/buildroot/buildroot-201902/system/skeleton

If ineffective, use the cleanup commands above and recompile.
