Yocto 4/4.1（Kirkstone/Langdale）树莓派启动失败求助

我尝试在树莓派4上部署Yocto 4或4.1（对应Kirkstone/Langdale分支）版本，编译生成镜像并烧录到SD卡后，设备启动2-3秒就崩溃，无法正常进入系统。已确认SD卡和电源均无故障——Yocto 3.1版本可以正常启动运行。

我的bblayers.conf配置 #

# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
  /local/home/my_user/rpi_builds/langdale/poky/meta \
  /local/home/my_user/rpi_builds/langdale/poky/meta-poky \
  /local/home/my_user/rpi_builds/langdale/poky/meta-yocto-bsp \
 /local/home/my_user/rpi_builds/langdale/poky/meta-raspberrypi \
 "

local.conf配置片段 #

...
    MACHINE ?= "raspberrypi4-64"
    IMAGE_FSTYPES = "tar.xz ext3 rpi-sdimg"
...

烧录命令 #

sudo dd if=core-image-minimal-dev-raspberrypi4-64.rpi-sdimg of=/dev/disk4 

想请教大家，Yocto 4.0及以上版本是否确实支持树莓派运行？我目前能找到的教程都基于Dunfell版本。启动崩溃前1秒的屏幕截图显示系统刚输出少量启动日志就突然终止，无后续正常启动流程。
