We don't want to do "make modules" again, as this will change the root filesystem (surely by reinstalling the same thing, but still), while we are exactly in the process of adding the filesystem to the kernel image. > > I think I would prefer to have: > > > > $(call LINUX_INSTALL_IMAGE,$(BINARIES_DIR)) > > Ok, just wondering, why?

And in general, I don't like too much seeing the _CMDS variables called from other variables. Thomas

In your commit 055e6162bba7 ("linux: don't build appended DTB image in place and support multiple images") you indicated: ----- <snip> Some of the tested configuration: - Normal uImage with several DTBs BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7" BR2_LINUX_KERNEL_UIMAGE=y BR2_LINUX_KERNEL_UIMAGE_LOADADDR="0x200000" BR2_LINUX_KERNEL_DTS_SUPPORT=y BR2_LINUX_KERNEL_INTREE_DTS_NAME="armada-xp-matrix armada-xp-gp armada-370-mirabox" Contents of output/images/: armada-370-mirabox.dtb armada-xp-gp.dtb armada-xp-matrix.dtb uImage <snip> ----- Hence, the DTB images are intended to be copied to output/images/ under some circumstances, right? How would that work? I mean, there's no call to LINUX_INSTALL_DTB on "$(LINUX_DIR)/.stamp_initramfs_rebuilt". Or does that happens through LINUX_INSTALL_TARGET_CMDS and package/pkg-generic.mk's "$(BUILD_DIR)/%/.stamp_target_installed" target? In that case I think I don't understand why we enter in "$(LINUX_DIR)/.stamp_initramfs_rebuilt" target, given there's a target $(BUILD_DIR)/%/.stamp_images_installed that calls LINUX_INSTALL_IMAGES_CMDS. Best regards, Sebastian

The target "$(LINUX_DIR)/.stamp_initramfs_rebuilt" uses its own 'cp' command, instead of LINUX_INSTALL_IMAGE/LINUX_INSTALL_IMAGES_CMDS provided by (or updated with) 055e6162bba7 ("linux: don't build appended DTB image in place and support multiple images") and thus is not operating properly when APPENDED_DTB is used. Indeed, it copies a single image, and does not copy the one with the DTB appended. This patch replaces the 'cp' command with $(LINUX_INSTALL_IMAGES_CMDS) which handles APPENDED_DTB. It also makes the copy verbose so that the user can see how many images were copied.
