With a 100+MB rootfs, you might want to consider using SD card or NFS for the
rootfs. Would save a lot of time...

Hi,
How to config yocto to include CRC information?
You are mis-reading the error, the CRC check is informing you that the
ramdisk is corrupt (aka it doesn't match the CRC). This is because
your ramdisk is 102MB, which will not fit between the memory range
0x6000000 to 0x7000000 (a 16MB segment). And when you load the dtb at
0x7000000 it will overwrite part of your rootfs image.
Just swap the addresses you are using for the dtb and rootfs, this
will make sure the rootfs has more than enough space to load into
memory.

Hi Nathan
I am not aware of that uImage is obsoleted for arm64, could you tell
me how to use booti command to boot linux?
What address and how to set dtb and rootfs?
Ah, now we're getting to the real question.
Just looking at the u-boot source code reveils how it's done:
https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_Xilinx
_u-2Dboot-2Dxlnx_blob_master_include_configs_xilinx-5Fzynqmp.h-23L189&

booti $kernel_addr - $fdt_addr
Yep, works the same as the other boot* style commands. The following addresses
should work for zynqmp:
tftpboot 0x80000 Image
tftpboot 0x6000000 core-image-minimal-ep108-zynqmp.cpio.gz.u-boot
tftpboot 0x7000000 Image-zynqmp-ep108.dtb booti 0x80000 0x6000000 0x7000000

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.

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.
You can, KERNEL_IMAGETYPES += "<extra ones>"
