    1. git clone the repo (https://github.com/StaticRocket/lightweight-offscreen)
    2. in the SDK directory source environment-setup-aarch64-oe-linux
    3. create the crossfile and place it in /home/user/ti-processor-sdk-linux-adas-j721s2-evm-09_02_00_05/linux-devkit/sysroots/x86_64-arago-linux/usr/share/meson/aarch64-oe-linux-meson.cross as shown here:
      [binaries]
c = '/home/user/tisdk_releases/j7aep/902/ti-processor-sdk-linux-adas-j721s2-evm-09_02_00_05/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-gcc'
cpp = '/home/user/tisdk_releases/j7aep/902/ti-processor-sdk-linux-adas-j721s2-evm-09_02_00_05/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-g++'
ar = '/home/user/tisdk_releases/j7aep/902/ti-processor-sdk-linux-adas-j721s2-evm-09_02_00_05/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-ar'

pkgconfig = 'pkg-config'

[built-in options]
c_args = ['--sysroot=/home/user/tisdk_releases/j7aep/902/ti-processor-sdk-linux-adas-j721s2-evm-09_02_00_05/linux-devkit/sysroots/aarch64-oe-linux', '-mbranch-protection=standard']

[host_machine]
system = 'linux'
cpu_family = 'aarch64'
cpu = 'armv8-a'
endian = 'little'
    4. Now inside the repo configure the build by running meson setup build --buildtype=release
    5. Build the demo with ninja -C build
    6. Copy the executable in the build directory of the repo onto the target and run the demo.

    Attaching the crossfile to download here:

    aarch64-oe-linux-meson.cross

    The demo is built against the 9.2 SDK's sysroots but can be built against any SDK's sysroots. Just follow the respective steps and change the file locations in the crossfile.
