uImage is not a valid target for aarch64/arm64 in the kernel (like it is for arm). This is because "uImage" is actually shorthand for u-boot wrapped zImage. And arm64 does not have support for zImage, thus also does not have a uImage target. (arm targets) https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/Makefile?id=refs/tags/v4.8#n365 (arm64 targets) https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/Makefile?id=refs/tags/v4.8#n135 --- A good question is why do you want to use uImage? If you are not aware it is possible to boot a linux "Image" with the U-Boot "booti" command. However it is possible to wrap the kernel image with mkimage (or a FIT blob if you are prepared to configure the image tree). For wrapping with mkimage the command you will need is similar to: mkimage -A arm64 -O linux -T kernel -C none -a 0x80000 -e 0x80000 -d Image Image.ub Also if you need mkimage, run the command using the mkimage built by OE from the sysroot relative to the tmp/deploy/images/<machine>/ directory of your build (assuming you are on a x86_64 host): ../../../sysroots/x86_64-linux/usr/bin/mkimage ... >> >> >> Could you tell me how to build uImage rather than Image > > > Just setting KERNEL_IMAGETYPE="uImage" in the kernel recipe or machine > config would do that. > > I think you can even specify multiple types in there.
