hi,i want boot my linux kernel on my banana pi M2u board,and i build uboot like follow on my debian 8

  1. export ARCH=arm
  2. export CROSS_COMPILE=arm-linux-gnueabihf-
  3. make Bananapi_M2_Ultra_defconfig O=out
  4. cd out
  5. make -j then i burn uboot and kernel by fel as follow sudo sunxi-tools/sunxi-fel uboot u-boot-sunxi-with-spl.bin write 0x43000000 uImage write 0x44000000 sun8iw11p1-sata.dtb and when uboot start ,i run 'bootm 43000000 - 44000000' in uboot and it say '

    Booting kernel from Legacy Image at 43000000 ...

    Image Name: Linux-3.10.65 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 3149960 Bytes = 3 MiB Load Address: 40008000 Entry Point: 40008000 Verifying Checksum ... OK

    Flattened Device Tree blob at 44000000

    Booting using the fdt blob at 0x44000000 Loading Kernel Image ... OK reserving fdt memory region: addr=78000000 size=8000000 reserving fdt memory region: addr=43000000 size=800 Loading Device Tree to 49fec000, end 49fffa92 ... OK

Starting kernel ... ' and then nothing print, i check uboot code and find that dev die on u-boot-sunxi/arch/arm/lib/bootm.c -> announce_and_cleanup -> dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);

i disable non-secure support on run 'make menuconfig' ARM architecture ---> Enable support for booting in non-secure mode and boot linux OK, i don't know why,can't anyone talk to me? sorry for my poor english

Booting non-secure with mainline U-boot is only supported for mainline Linux.

If you want to use Allwinner's kernel and boot non-secure, I suggest you use their bootloaders as well.
