Yocto wic和fitImage的循环依赖性问题+；Initramfs

我试图建立sd卡形象使用wic在Yocto。发现如果我使用bundle initramfs启用fitImage会触发错误。如果我禁用INITRAMFS\u图像，它可以正常工作。如何解决此循环依赖关系问题

在initramfs图像配方（在

initramfs\u image

中指定的配方）中，将

wic

作为

image\u FSTYPE

删除。这应该只为initramfs映像删除它，并允许主映像仍然构建wic映像

IMAGE_FSTYPES_remove = " wic wic.gz"

我使用自定义映像类型bbclass来处理这种配置，我没有为此使用内核fitimage。这是一种方法，但我更喜欢使用尽可能多的标准yocto特性。
