Problem about compiling Kernel for NanoPi-NEO

I want to compile kernel for my own use. So, I tried making kernel by loading config-4.9-sun8i in linux-4.9 and got zImage.
But, after moved into boot dir and booted, on serial, the kernel was loaded and uncompressed is okay, then stuck.
So, I got the armbian for nanopi-neo to be tested (config-4.9.4-sun8i in linux-4.9.4) and result is the same.

What am I missing?
