Adding support for STM32F303 #213

Closed minexew closed 6 years ago

minexew commented 7 years ago

Hi, I'm interested in adding support for the STM32F303 line of microcontrollers. I would appreciate any guidance on where to start.

What I'm particularly confused about is the relation between Ada_Drivers_Library and AdaCore/embedded-runtimes. To support the line of MCUs, would both projects need to be updated?

Also, embedded-runtimes vs bb-runtimes?

Hi @minexew,

I'm interested in adding support for the STM32F103 line of microcontrollers. I would appreciate any guidance on where to start.

That's great! We will do our best to help you.

The first thing to do is to have a working run-time. I know there are some discussion about STM32F103 support in the IRC #ada channel, we also have a porting guide on the blog however it was published one and half year ago so part of it is not relevant anymore.

What I'm particularly confused about is the relation between Ada_Drivers_Library and AdaCore/embedded-runtimes. To support the line of MCUs, would both projects need to be updated?

About Ada_Drivers_library vs bb-runtimes, I wrote a small explanation text that I want to get reviewed before publishing it. I will keep you updated. The short answer is that you will first need a run-time (in the repo bb-runtimes) then you will be able to work on drivers (in the repo Ada_Drivers_Library).

About bb-runtimes vs embedded-runtimes, embedded-runtimes is deprecated. It is an intermediate representation between the sources (now in bb-runtimes) and the installation that you get in the compiler. Now that we published the bb-runtime repository, there's no need to use embedded-runtimes anymore. New contributions should be made to bb-runtime directly and we will add a notice in the embedded-runtimes repo.

Sorry for the mistake, I meant F303 which is based on the Cortex M4F..

That means it will be easier for you to port the run-time, it will mostly be a BSP work. You can start from here AdaCore/bb-runtimes/tree/gpl-2017/arm/stm32, copy the stm32f40x directory into a new stm32f30x and change what is needed for the 303.

Yeah... I didn't get far.
