This README file contains information on the contents of the meta-openharmony layer.

Please see the corresponding sections below for details.

This layer depends on the following Yocto meta-layers:

URI: poky/meta
branch: kirkstone

URI: poky/meta-poky
branch: kirkstone

URI: poky/meta-yocto-bsp
branch: kirkstone

URI: meta-openembedded/meta-oe
branch: kirkstone

URI: meta-openembedded/meta-filesystems
branch: kirkstone

URI: meta-openembedded/meta-python
branch: kirkstone

URI: meta-openembedded/meta-networking
branch: kirkstone

URI: meta-openharmony
branch: kirkstone

URI: meta-virtualization
branch: kirkstone

To add the meta-openharmony layer to your Yocto build, run the following command:

bitbake-layers add-layer meta-openharmony

You must define the OHOS_DIR environment variable, either in your local.conf file or as an environment variable in your shell.

OHOS_DIR should point to the root directory of your OpenHarmony build environment.

Example (in local.conf):

OHOS_DIR = "/path/to/openharmony"

This layer includes:

• Patches for the Linux kernel to support OpenHarmony.
• LXC container configuration files to launch the OpenHarmony system.
• A recipe to package the OpenHarmony root filesystem (rootfs) into a deployable image.

Before building the Yocto image, you need to generate the OpenHarmony rootfs tarball using the OpenHarmony build system.

Run the following command from within the OpenHarmony source directory:

./build.sh --product-name qemu --build-target rootfs_pkg

This will create a tarball containing the OpenHarmony rootfs, which is used by this meta-layer during the Yocto build process.

To build the OpenHarmony Yocto image, run the following command:

DISTRO=openharmony MACHINE=qemuarm64 bitbake openharmony-standard-image

This will generate the OpenHarmony image for the specified machine and distribution.

After building the OpenHarmony Yocto image, you can run it using QEMU with the following command:

DISTRO=openharmony MACHINE=qemuarm64 runqemu openharmony-standard-image serialstdio

This will launch the OpenHarmony image in QEMU with serial I/O redirected to the terminal.

This layer enables integration of OpenHarmony as a guest containerized system in a Yocto-based environment, suitable for embedded and virtualization use cases.

Make sure all dependencies are properly added and OHOS_DIR is correctly configured before starting the build process.
