hexdump，thank you for reply my question.I bought another X96Airbox,and installed Armbian in sdcard ,but I could not install Armbian in emmc ,this forum said this box is too new to support it,so I thougt of running Armbian in h96max to have a try.

@hexdump，I have a h96max Rk3318 box 4+32GB,as you say, this tvbox could not boot from usb,I flash usb and sdcard from image of Armbian_20.02.0-rc1.038_Rk3328-tv_bionic_current_5.5.0-rc6_20200205.img,dd my as follows , dd if=./uboot-rk3318-h96max.img of=/dev/sdb seek=16384 conv=sync,fsync dd if=./trust.img of=/dev/sdb seek=24576 conv=sync,fsync rename uboot.sd to uboot.ext, and edit config in uEnv.txt # rk-3328 FDT=/dtb/rockchip/rk3318-h96max.dtb #FDT=/dtb/rockchip/rk3328-box.dtb #APPEND=root=LABEL=ROOTFS rootflags=data=writeback rw console=uart8250,mmio32,0xff130000 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 then insert sdcard and usb in box,turn on power with toothstick in AV hole,but no hdmi appears,as if my box have not boot yet. @hexdump,could you explain if I made some mistake from using your uboot-rk3318-h96max.img and rk3318-h96max.dtb,why your box booting normally. thanks - chess12
