the exact image version, TV box model, detailed steps that were performed for DTB settings, My TV box is Phicomm N1, and I tried the "Armbian_20.10_Arm-64_bullseye_current_5.9.0_desktop.img.xz" image, followed the instraction, edited extlinux.conf to LABEL Armbian LINUX /zImage INITRD /uInitrd FDT /dtb/amlogic/meson-gxl-s905d-phicomm-n1.dtb APPEND root=LABEL=ROOTFS rootflags=data=writeback rw console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 and renamed u-boot-s905x-s922 to u-boot.ext, the TV box can boot, but cannot bootfrom the u-key, what should I do? Look forward to your favourable reply.
