In the x86 world (Intel/AMD), an ISO file contains a generic kernel that detects your hardware at boot via ACPI and UEFI. ARM hardware does not work this way. On ARM, the Device Tree Blob (DTB) tells the kernel exactly what hardware exists. A DTB for a Rockchip RK3588 will simply not boot on an Allwinner H6. armbian iso
