Some initramfs bundled code exist in wr-kernel but not compatible with upstream.
1 configure a project 2 check the wr-kernel/recipes-kernel/linux/linux-windriver.inc for: ...... INITRAMFS_BASE_NAME = "${KERNEL_IMAGETYPE}-initramfs-${PV}-${PR}-${MACHINE}-${DATETIME}" INITRAMFS_BASE_NAME[vardepsexclude] = "DATETIME" do_bundle_initramfs[depends] += "virtual/kernel:do_install" ...... the exact same code exist in oe-core layer already.
