@szlin can you please check this?

Hi @jarun @optio50

I have tested nnn 2.2-1 package in native armhf device - Cortex A15 (kernel 4.14.44) and qemu armhf environment (kernel 4.18.6).

Both of them work well.

Currently, the Debian armhf port requires at least an Armv7 CPU. However, Rasppberry pi Zero uses Armv6 CPU. That means you should use armel instead of armhf with nnn or use custom kernel [1].
