最新的AMD PetaLinux 2022.1，不支持IMAGE_CLASSES_remove、IMAGE_FSTYPES_DEBUGFS_remove、PREMIRRORS_prepend。如果有上述关键词，会报告类似下面的错误。

代码语言：javascript复制You can now run 'bitbake <target>'
Common targets are:
core-image-minimal
core-image-full-cmdline
core-image-sato
core-image-weston
meta-toolchain
meta-ide-support
You can also run generated qemu images with a command like 'runqemu qemux86-64'.
Other commonly useful commands are:
- 'devtool' and 'recipetool' handle common recipe tasks
- 'bitbake-layers' handles common layer tasks
- 'oe-pkgdata-util' handles common target package tasks

下面是2022.1之前的设置，去掉一些不用的文件系统映像。
代码语言：javascript复制IMAGE_FSTYPES_remove = " .bin tar.gz tar.bz2 ext4 ext4.gx ext4.gz ext3 ext3.bz2 jffs2 cpio.bz2 cpio.xz cpio.lzma cpio.lz4"
IMAGE_FSTYPES_DEBUGFS_remove = " .bin tar.gz tar.bz2 ext4 ext4.gx ext4.gz ext3 ext3.bz2 jffs2 cpio.bz2 cpio.xz cpio.lzma cpio.lz4"上述设置，在PetaLinux 2022.1中，可以更改为如下：
代码语言：javascript复制IMAGE_FSTYPES:remove = " .bin tar.gz tar.bz2 ext4 ext4.gx ext4.gz ext3 ext3.bz2 jffs2 cpio.bz2 cpio.xz cpio.lzma cpio.lz4"
IMAGE_FSTYPES_DEBUGFS:remove = " .bin tar.gz tar.bz2 ext4 ext4.gx ext4.gz ext3 ext3.bz2 jffs2 cpio.bz2 cpio.xz cpio.lzma cpio.lz4"对于AR71198中推荐的额外下载链接设置PREMIRRORS_prepend，也不能再使用。
代码语言：javascript复制PREMIRRORS_prepend = "
