OK3568 4.19.206 Buildroot Tailoring and Removal of QT-Related Elements in File System

Note: After the full compilation of the source code is complete, take a virtual machine snapshot to prevent subsequent operations from causing compilation failures.

1. Delete the following content from the filesystem configuration file Ok3568_defconfig:

BR2_PACKAGE_FORLINX_QT=y       // Forlinx Qt test demo  
BR2_PACKAGE_FORLINX_CMD=y      // Forlinx command-line test demo  
BR2_PACKAGE_QT5*=y             // Qt-related library support  
#include "qt.config"            // Qt-related library support

Operation command:

forlinx@DESKTOP-ARR08M4:~/3568.4.19/OK3568-linux-source$ cd buildroot/configs/
forlinx@DESKTOP-ARR08M4:~/3568.4.19/OK3568-linux-source/buildroot/configs$ vi OK3568_defconfig

Delete the following content.

2. Delete the stamp file, otherwise modifications to OK3568_defconfig will not take effect.

forlinx@DESKTOP-ARR08M4:~/3568.4.19/OK3568-linux-source/buildroot/output/OK3568/build$ rm -rf ./*/.stamp_target_installed

3. Delete the existing filesystem.

forlinx@DESKTOP-ARR08M4:~/3568.4.19/OK3568-linux-source/buildroot/output/OK3568/build$ cd ..
forlinx@DESKTOP-ARR08M4:~/3568.4.19/OK3568-linux-source/buildroot/output/OK3568$ rm -rf target/

4. Regenerate the filesystem.

forlinx@DESKTOP-ARR08M4:~/3568.4.19/OK3568-linux-source$ ./build.sh  buildroot

The newly generated filesystem will be located in the path:

OK3568-linux-source/buildroot/output/OK3568/images/

forlinx@DESKTOP-ARR08M4:~/3568.4.19/OK3568-linux-source/buildroot/output/OK3568/images$ pwd
/home/forlinx/3568.4.19/OK3568-linux-source/buildroot/output/OK3568/images		//The location is
forlinx@DESKTOP-ARR08M4:~/3568.4.19/OK3568-linux-source/buildroot/output/OK3568/images$ ls
rootfs.cpio  rootfs.cpio.gz  rootfs.ext2  rootfs.ext4  rootfs.squashfs  rootfs.tar

Flash the newly generated rootfs.ext2 using the single-step flashing method.

If you need to generate a new firmware update.img, execute the following command in the OK3568-linux-source/ directory: build.sh. is OK. The update.img file will be generated in the OK3568-linux-source/rockdev/ directory.

Tip: For other unnecessary features, follow this operation method to cancel the compilation configuration.
