Pocket Chip Debian 10 Upgrade Guide

The purpose of this tutorial is to walk through the required steps to upgrade NXT chip (or pocketchip) from debian jessie to debian buster.

If you would like to start your Chip from scratch, follow the steps in the Preparation section.

Preparation (Optional)

A linux host machine, recommended Ubuntu 18.04. However I managed to do it with 20.10 with some tweak.

Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

• Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
• Microsoft Windows 7 SP1 as the host OS
• A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

SDCC - Interfacing with Z80 assembler code

The basics

When writing code to be compiled with SDCC targetting Z80, assembler code fragments can be inserted in the C functions by enclosing them between the __asm and __endasm; tags:

void DoNotDisturb()
{
  __asm

DX7

Note: One of the algorithms is incorrect due to a missing operator. Need to update the image. Will have to get on that soon.

These are the original 32 algorithms as used in Yamaha DX7.

The later Yamaha FS1R and Yamaha SY77 may have compatibility with these algorithms, but that's beyond the current scope. The FS1R contains 88 algorithms, while the SY77 contains 45 algorithms.
