One advantage of using a virtual machine is that you can allocate a separate virtual disk file and mount it on the Linux system, and save the /home directory, installed software, SDK, and self-written code separately to this virtual disk file. This way, it will not be mixed with the original Linux system and other software, making it easier to manage and migrate.
(Follow-up: downgrade from Ubuntu-22.04.1 to Ubuntu-18.04.6 to experience this convenience.)
Compilation was performed according to the document compilation process. During the compilation, insufficient disk space occurred, and finally the disk expansion function of VMware was used to solve the problem.

ERROR: OE-core's config sanity checker detected a potential misconfiguration.
Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
Following is the list of potential problems / advisories:
Fetcher failure for URL: 'https://www.example.com/'. URL https://www.example.com/ doesn't work.
Please ensure your host's network is configured correctly.
If your ISP or network is blocking the above URL,
try with another domain name, for example by setting:
CONNECTIVITY_CHECK_URIS = "https://www.yoctoproject.org/" You could also set BB_NO_NETWORK = "1" to disable network
access if all required sources are on local disk.
bitbake -c populate_sdk myir-image-core

WARNING: Host distribution "ubuntu-22.04" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution.

2.2.3. Incompatibility with Windows shared file systems
The downloads directory is unzipped to a data disk (NTFS file system format) under Windows, and then in the Ubuntu system, a symbolic link "downloads" is created in the myd-jx8mma7-yocto/directory to point to the downloads directory under Windows (through the shared directory mechanism of the virtual machine). As a result, the following error is found:
fatal: detected dubious ownership in repository at '/mnt/hgfs/Repo0/Downloads/Yocto-download-5.10/downloads/git2/git.savannah.gnu.org.config.git'
To add an exception for this directory, call:
git config --global --add safe.directory /mnt/hgfs/Repo0/Downloads/Yocto-download-5.10/downloads/git2/git.savannah.gnu.org.config.git
Solution:
Re-extract to the Linux file system.
2.2.4. Incompatible Python versions lead to script errors
ImportError: cannot import name ‘Mapping’ from ‘collections’ (D:Program FilesPythonlibcollections__init__.py)
Cannot import name 'mapping' from 'collections' because Python 3.10 and later versions have adjusted the requests library, and methods Mapping and MutableMapping cannot be called directly in collections.
The solution is to find the __init__.py file that references the collections module and adjust the import from abc:
There are too many files affected to modify them one by one. Install Python-3.9

I don't want to mess with Ubuntu-22.04.1 anymore, so I'll just follow the documentation and proceed step by step.
2.3. Compile Yocto on Ubuntu-22.04.1
After installing Ubuntu-18.04.6, basically everything went smoothly and peacefully. . . .
DISTRO=fsl-imx-xwayland MACHINE=myd-jx8mma7 source myir-setup-release.sh -b build-vdisk1
You can now run 'bitbake <target>'
Common targets are:
core-image-minimal
meta-toolchain
meta-toolchain-sdk
adt-installer
meta-ide-support
After setup, the files in the build directory are as follows:

Summary: There was 1 ERROR message shown, returning a non-zero exit code.
Cause Analysis:
During the build process, git was updated but failed due to network problems.
Solution: (TODO)
It's troublesome to climb over the wall and put up a ladder.
Disable network updates and just use locally downloaded code.
