And you are applying also a fixup script. These patches should be applied on top of linux mainline. fixup script: Applying kernel provided DT fixup script (sun6i-a31s-fixup.scr) Linux versions: 4.15.0-00003-g1bbe5edde691 vs 4.15.0-sunxi-dirty In addition to that you are also booting into fb/hdmi. If you use my branch (uImage and dtb) and replace the current boot.cmd with this (to get the boot.scr you need to use mkimage) it should work: setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait panic=10 load mmc 0:1 0x43000000 ${fdtfile} || load mmc 0:1 0x43000000 boot/${fdtfile} load mmc 0:1 0x42000000 uImage || load mmc 0:1 0x42000000 boot/uImage bootm 0x42000000 - 0x43000000
