ARMNN compiled for Raspberry Pi 2 Model B V1.1 (Cortex-A7)

Description

While trying this, I needed to setup Arm NN for Raspberry Pi.

There are 2 introduced ways + 1 additional way to do this.

1. ARM reference guide which isn't managed properly
2. ARM official build script which generates 'armnn-devenv', not tarball file
3. ARM officiai github guide which is based on arm64

Mostly, these guides assume AArch64(or ARMv8 ISA), while Raspberry Pi 2 has 32-bit processor(ARMv7 ISA). Moreover, some of them doesn't even work and are wrong!

So I made my way out of it.

Tested Environment

macOS 10.15.7 (19H2)

vmware fusion player version 12.0.0 (16880131)

ubuntu 18.04.5

File description

• armnn-dist.tar.gz

compiled and compressed tarball, result of instruction.sh

copy this file to /home/pi of Raspberry Pi and follow instruction of ARM reference guide's "Extract the libraries, binaries, and directories to your Raspberry Pi" section to move along & test

• instruction.sh

source instruction script

took about 2 hours on my machine (allocated 4GB of RAM on VM)
