This is a mini-tutorial of sorts for getting started with gdb on the Switch, with the target audience being people who want to mod and/or reverse games, with no prerequisite knowledge of gdb. The goal will be to walk you through some of the basic workflows needed to use a debugger on the Switch, while being brief enough for skimming for when you forget things.

If some part is unclear, your OS doesn't have install instructions, or you feel part of your workflow should be added here, feel free to comment any additions.

Installing GDB

First off you'll need a version of GDB compatible with aarch64. This can be obtained via either a distribution of

iUltimateLP

// DynamicTexture

#include "DynamicTexture.h"

// UTextures have a BPP of 4 (Red, Green, Blue, Alpha)
#define DYNAMIC_TEXTURE_BYTES_PER_PIXEL 4

void UDynamicTexture::Initialize(int32 InWidth, int32 InHeight, FLinearColor InClearColor, TextureFilter FilterMethod/* = TextureFilter::TF_Nearest*/)
{
	// Store the parameters

This will only work in cooked builds with Event Driven Loader enabled (enabled by default). Currently this only shows the specified packages loading progress, but not dependant packages, which is an annoying issue since that is where most of the loading time is for maps.

TPM2 Protocol Implementation

Introduction

Frame data is transferred inside packets (similar to DMX, for example). A frame is an image representing a matrix or a light scene.

The packets start and end with one-byte characters. In between are a few control bytes followed by the payload. There is no set size for a payload; it is transmitted with each packet. This makes the protocol quite flexible. There are enough bytes in a single packet for an RGB matrix with 21,845 pixels, but if you just want to control an RGBW lamp, that only requires 9 bytes. The variable frame size means there is no overhead, allowing for maximum transfer speed.
