Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

Run the following in your terminal

## To download the OpenNMT library
git clone https://github.com/OpenNMT/OpenNMT-py
cd OpenNMT-py

## Installing the requiremnets
pip install -r requirements.txt

## Downloading the data (if wget not avilable, then download using a browser by going to the link)

If you get an "Invalid name" error when you run npm init -y, rename the project folder to only contain lowercase ASCII letters or hyphens (e.g. my-project), and try again.

	MinGW doesn't provide a linux-like environment, that is MSYS(2) and/or Cygwin

	Cygwin is an attempt to create a complete UNIX/POSIX environment on Windows.
	MinGW is a C/C++ compiler suite which allows you to create Windows executables - you only
	need the normal MSVC runtimes, which are part of any normal Microsoft Windows installation.

	MinGW provides headers and libraries so that GCC (a compiler suite,
	not just a "unix/linux compiler") can be built and used against the Windows C runtime.
