Build a Yocto Image

The process of building with the bitbake command needs to ensure that the network connection is normal. If it is a customer in inland China, you need to ensure that it can ping the external network.

Enter the directory <path/to/yocto/poky> and execute the following commands in sequence:

# Install the required environment packages
# sudo apt install zstd
source oe-init-build-env

# add layer
bitbake-layers add-layer ../../meta-openembedded/meta-oe
bitbake-layers add-layer ../../meta-openembedded/meta-python
bitbake-layers add-layer ../../meta-openembedded/meta-networking
bitbake-layers add-layer ../../meta-openembedded/meta-multimedia
bitbake-layers add-layer ../../meta-openembedded/meta-gnome
bitbake-layers add-layer ../../meta-openembedded/meta-xfce
bitbake-layers add-layer ../../meta-lts-mixins
bitbake-layers add-layer ../../meta-clang
bitbake-layers add-layer ../../meta-browser/meta-chromium
bitbake-layers add-layer ../../meta-rockchip

Choose one of the commands to compile the complete core-image recipes. The following is an X11-based core image:

MACHINE=aio-1126bjd4 bitbake core-image-minimal
MACHINE=aio-1126bjd4 bitbake core-image-minimal-xfce
MACHINE=aio-1126bjd4 bitbake core-image-x11
MACHINE=aio-1126bjd4 bitbake core-image-sato

The following is a core image based on Wayland. Modify DISPLAY_PLATFORM to wayland in /path/to/yocto/meta-rockchip/conf/machine/include/display.conf:

DISPLAY_PLATFORM ?= "wayland"
# DISPLAY_PLATFORM ?= "x11"

After completing the modification, compile core-image-weston:

MACHINE=aio-1126bjd4 bitbake core-image-weston

If you need to change the compiled core-image recipes after already compiling one, clean the currently compiled core image before compiling the new one.

For example, to change from core-image-minimal to core-image-sato:

MACHINE=aio-1126bjd4 bitbake core-image-minimal -c clean
MACHINE=aio-1126bjd4 bitbake core-image-sato

If you want to compile some recipes separately, use the following commands:

# kernel
MACHINE=aio-1126bjd4 bitbake linux-rockchip

# u-boot
MACHINE=aio-1126bjd4 bitbake u-boot-rockchip

# rkmpp
MACHINE=aio-1126bjd4 bitbake rockchip-mpp

# rockchip-librga
MACHINE=aio-1126bjd4 bitbake rockchip-librga

# See more compilation objects
MACHINE=aio-1126bjd4 bitbake -s
