Configure UART

Network setup

echo "auto eth0" > /etc/network/interfaces.d/eth0
echo "iface eth0 inet dhcp" >> /etc/network/interfaces.d/eth0
echo "nameserver 8.8.8.8" >> /etc/resolv.conf
echo "nameserver 8.8.4.4" >> /etc/resolv.conf

Exit FileSystem

exit
./ch-mount.sh -u root/

packaged FileSystem

cd root
tar -cjf rootfs.tar.bz2 ./*

Deploy FileSystem to SD Card

Prepare a SD card with ext4 partition: Learning/Linux#Partitioning and Formatting an SD Card

extract ubuntu .bz2 package to SD card

sudo tar -xvf rootfs.tar.gz -C /media/xxx/rootfs

Install Wayland, Wayland-Protocols and Weston

Environment Setup

Compile and install Wayland

Copy the Wayland 1.18.0 source code from VLP Yocto build folder to SD card.

i.e. build/tmp/work/aarch64-poky-linux/wayland/1.18.0-r0/wayland-1.18.0/

Compile and install Wayland-protocol

Copy the wayland-protocol1.20.0 source code from VLP Yocto build folder to SD card.

i.e. build/tmp/work/aarch64-poky-linux/wayland-protocols/1.20-r0/wayland-protocols-1.20/

Compile and install Weston

Copy the weston8.0.0 source code from VLP Yocto build folder to SD card.

i.e. build/tmp/work/aarch64-poky-linux/weston/8.0.0-r0/weston-8.0.0/

If the configuration is correct, it will display below messages

User defined options
    libdir : /usr/lib/aarch64-linux-gnu
    prefix : /usr
    sysconfdir : /etc
    backend-drm-screencast-vaapi : false
    color-management-colord : false
    remoting : false
    xwayland : false

Port GPU Libraries

Please refer to the StartupGuide.txt document in meta-rz-features/recipes-graphics/mali/files/mali_pkg_eval_vx.x.tar.gz

Migrate GPU drivers

Copy the driver mali_kbase..ko from VLP Yocto build folder to SD card.

i.e. build/tmp/work/smarc_rzg2l-poky-linux/kernel-modulemali/r35-p0/image/lib/modules/5.10.83-cip1-yocto-standard/extra

Migrate GPU Libraries

Copy the library files to SD card.

i.e.  meta-rz-features/recipesgraphics/mali/files/mali_pkg_eval_vx.x.tar.gz

Testing

Install testing tool

sudo apt install glmark2-es2-wayland

Start Weston desktop

Only root user can launch weston service, please switch to root user in advance

insmod mali_kbase.ko

export XDG_RUNTIME_DIR=/usr/lib/
export RUNLEVEL=3

weston --tty 1 &

Run glmark2 test

glmark2-es2-wayland --fullscreen

glmark2 version	glmark2 result

Port codec Librasries

In this section, we will copy codec related files from original VLP Yocto build.

i.e. core-image-qt-smarc-rzg2l.tar.bz2 or core-image-weston-smarc-rzg2l.tar.bz2

Pleaes copy this .bz2 file to Ubuntu SD card and run below instruction on reference board

unzip core-image-qt-smarc-rzg2l.tar.bz2 or core-image-weston-smarc-rzg2l.tar.bz2 to folder "yocto"

Test gstreamer

Port Qt

You can port Qt by following 3 methods

• Port from VLP
• Compile & Install Qt from source
• Install Qt by apt-get

Port from VLP

In this section, we will copy Qt5.6.3 related files from original VLP Yocto build.

i.e. core-image-qt-smarc-rzg2l.tar.bz2

Pleaes copy this .bz2 file to Ubuntu SD card and run below instruction on reference board

unzip core-image-qt-smarc-rzg2l.tar.bz2 to folder "yocto"

(For other version of Qt, you can modify Yocto meta-qt5\recipes-qt\qt5, please inqury Qt company for higher version QT integration)

Start Weston RZ-G/RZ-G2 BSP Porting Ubuntu#Start Weston desktop

Then run the Qt example in /usr/share/qt5/examples

Compile from source

You can download qt5 source to reference board and compile on board.

Or cross compile qt5 on PC

Or compile qt5 in PC QEMU

Here we compile qt5 on board

We suggest to compile the qt5 with scrips

Notes: About the flags parameter in configure of Qt5. -qpa should be set as wayland or wayland-egl. We didn't support xcomposite-egl option

Install Qt by apt-get

apt-get install qt5-default qtwayland5

Notes: The above installation commands can only run part of Qt functions. If you need more functions, you need to continue installing Qt related packages.

Qt APPs development and testing

This section introduce how to develop Qt application on PC.

SDK build and installation

bitbake core-image-qt -c populate_sdk

The generated installation file is located at:

build/tmp/deploy/sdk/poky-glibc-x86_64-core-image-qtaarch64-smarc-rzg2l-toolchain-3.1.14.sh

Install this SDK to PC, default folder is /opt/poky/3.1.14

setup SDK runtime environment

source /opt/poky/3.1.14/environment-setup-aarch64-poky-linux
