Dear All,

Think firstly have to define compiler tool chain so then used export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu- and try again, compiled but now same as for uboot. So for uboot which croos compile tool chain must be used and what must be the ARCH?

The ARCH & CROSS_COMPILE should be taken care of in the build.sh.

What's your compiling environment? We pass all builds in  64bits Ubuntu 16.04,
using ext4 or xfs filesystem.
