The nand-sata-install script is indeed quite old and not very actively maintained anymore. A common modern replacement on Odroid XU4 (and similar boards) is to use the Armbian installer built into armbian-config. You can run: Bash sudo armbian-config Then go to System → Install (or Install to SATA/USB/NVMe depending on your setup). Many people find it more reliable than the old nand-sata-install. Alternatively, you can do it manually with dd for U-Boot + rsync for the rootfs, but armbian-config is usually the easiest route these days. If you run into any issues with it, feel free to share the output and I can help walk you through it.

That error with mkimage during nand-sata-install is fairly common on XU4 and usually harmless if the system boots fine afterwards. The tool is a bit outdated and often throws this warning even when U-Boot is written correctly. Since it’s working after reboot, I wouldn’t worry about it.

Same situation here. The Orange Pi CM4 is not officially supported by Armbian and it doesn't look like it will be anytime soon. The Banana Pi CM4 image works best as a base (same SoC), but expect some missing features like NPU/video acceleration depending on the kernel. Official Orange Pi images are easier but come with all the usual vendor kernel issues.
