Getting started with ARM using OpenOCD and the BusPirate

This repository documents my progress with learning about ARM microcontrollers, the arm-none-eabi toolchain, OpenOCD and the Bus Pirate. I created it as a reference for others who try to learn the bare-metal basics.

I am using a STM32F103C8 microcontroller (the "bluepill") with a Bus Pirate v3.

TODO

• Installing OpenOCD from source
• Using the Standard Library (in progress)

Some useful pieces of documentation which helped me get started

• This was the most informive website on ARM I could find. Read this before doing anything else.
• This website and especially this page are a great manual on ARM assembly
• You should of course read the OpenOCD manual
• OpenOCD commands and Flash commands
• A great blog post on how to use and connect the BusPirate
• This StackOverlow question had some good information (especially the part with the Makefile)
• This Article is very informative
• STM32F103x8 datasheet
• RM0008 Reference manual
• STM32F10x standard peripheral library
