I have put a tutorial about coding bare metal on the R-PI, it using a basic like language, that users fasm macros called DexBasic (a cross between DexOS and FBasic).
But you could just as easy use fasmarm and call the functions.

I suspect the gooseberry is nothing other than a reference design which ARM provides to white box cellphone manufacturers in China and India

An interview with a founder and principal in the Raspberry Pi project.

Eben Upton

http://twit.tv/show/triangulation/61

Get the video version to see some of the user generated cases.

Why the name?

Why are there no version A's available?

Version 60 of this series was with Nolan Bushnell of Atari.

I have uploaded a new tutorial (3) using DexBasic in bare metal on the Pi.
http://www.dex-os.com/DexBasic/Lesson3.htm

This tutorial is on using the GPIO's.
I will update the language part of the site tomorrow with the new functions.

Note: I have implement the functions to be the same as the equivalent Arduino commands, so anyone who as programmed the arduino or tut available for the arduino, will be easy to convert.

Now they are claiming that Raspian OS runs 40% faster than Debian

Linux: Jack of all trades, master of none. I definitely respect the Linux project on their flexibility and the amount of resources they've brought to open source software. Without extensive optimization (as is the case with Raspian OS), however, Linux usually is a lackluster stopgap sort of operating system, rarely the most efficient use of any particular hardware. I'm glad to see they're working on optimizing Linux for their particular hardware, it will definitly result in a much more functional device.

I glanced at your webpage and it seems I've been looking for something like DexBasic. Cool, I'll check it out.

Let me know how you get on, i have done many more tuts, but have not uploaded them yet.
Also working on a add-on board for OS dev's, that adds keyboard and mouse support to the pi, without the need to write usb stack.

Great job, Dex! That give me the idea to restart osdeving again Smile

I'm curious to see the source code of the OS... just to know how it is made... Wink

Thank you for the link, Dex. This website contains all the things I needed to start coding for the RasPi.

http://www.cl.cam.ac.uk/freshers/raspberrypi/tutorials/os/

University of Cambridge is offering a 12-step online course on Ras-Pi

The course, Baking Pi - Operating Systems Development, is aimed at students of 16 and over with some prior programming experience, "although younger readers may still find some of it accessible, particularly with assistance"
