@Lexus that is created from the device tree, the .dts gets compiled and linked to the .img file

          	echo "ttyFIQ0" >> $ROOTFS_TEMP/etc/securetty
          
          	if [ "$LINUX" != "mainline" ]; then
          		execute_in_chroot "systemctl --no-reload enable bluetooth-khadas.service fan.service edge2-station.service"
          	fi
          
          	# Create boot links
          	if [ "$INSTALL_TYPE" == "EMMC" ]; then
          		execute_in_chroot "ln -fs /boot/Image Image"
          		execute_in_chroot "ln -fs /boot/initrd.img initrd.img"
          		execute_in_chroot "ln -fs /boot/dtb/rockchip/rk3588s-khadas-edge2.dtb dtb.img"
          		execute_in_chroot "ln -fs /boot/dtb dtb"
          	else
          		if [ "$LINUX" != "mainline" ]; then
          			execute_in_chroot "ln -fs dtb/rockchip/rk3588s-khadas-edge2.dtb /boot/dtb.img"
          		fi
          	fi
          
          	if [ "$DISTRIB_RELEASE" == "noble" ]; then

@Electr1 nice , You solved my headache and confusion！！ in addition，In khadas edge2 uboot, compared to Armbian, the uboot source code will also use this: “VNet ROCKCHIP_EARLY-DISTRO-DTB-PATH=”/dtb. img "??

@Lexus I have shared the linkage of dtb only in context of the fenix firmware, uboot has it’s own dts instance
