show your step of compile.

Author: jaganteki Time: 8/3/2017 13:05
ARCH=arm make rockchip_defconfig
or
ARCH=arm make rk3036_defconfig

ARCH=arm make LOADADDR=0x02000000 uImage dtbs -j 4

why 3036?

Author: jaganteki Time: 8/4/2017 18:40
I mean I tried these two defconfigs, and build issue came for both.
