Qt Root Filesystem

The X6818 Linux manual covers Qt filesystem setup, Buildroot configuration, Qt5.4 default example testing, Qt Creator installation, and default example compilation.

Download Buildroot​

Enter the source directory and download or extract Buildroot. Directory structure may differ by SDK version.

Configure Buildroot​

make menuconfig

Key items:

  • Target architecture and cross-toolchain.
  • Root filesystem type.
  • Qt5 / Qt5.4 components.
  • Touch, fonts, input method, network, audio, and library dependencies.
  • Example applications and debug tools.

Build Buildroot​

make

After the build, obtain the rootfs image, cross-toolchain, and target libraries from the output directory.

Test Qt5.4 Default Examples​

After flashing the Qt filesystem, run the default examples to verify display, touch, keys, audio, UART, network, and storage mounting.

Install Qt Creator​

On the PC, configure:

  • C/C++ compiler.
  • qmake.
  • sysroot.
  • Target device or remote debug settings.
  • Qt version and Kit.

Compile Qt Creator Default Example​

Create a Qt example project, select the cross-build Kit, build the target program, copy it to X6818, and run it.
