If you just want to do programming using the Component Pascal language on a Raspberry Pi I would recommend that you start by seeing if the Java Virtual Machine (JVM) version of Gardens Point Component Pascal will run on it. You can download it, including all source code, from:

http://gpcp.codeplex.com/releases/view/91967

It is well supported by the author (John Gough - a long time Modula-2 / Oberon / Component Pascal compiler designer) on the GPCP Yahoo Groups Forum:

http://tech.groups.yahoo.com/group/GPCP/

I believe that he is currently working on an LLVM-targeted version. My understanding is that this could make a native ARM version of GPCP possible in the future.

I have been using GPCP almost daily for more than seven years (albeit the .NET version not the JVM version) and have found it to be *extremely* robust and reliable.

Alternatively, if you want to use the Oberon operating system on a Raspberry Pi the first step is to get an ARM Oberon compiler that targets the Raspberry Pi's ARM11 microcontroller to work. Most of the existing Linux Oberon implementations I am aware of require a hardware platform that uses an Intel-compatible microprocessor.

The Raspberry Pi uses an ARM microcontroller - there are many different flavours of ARM microcontrollers with varying degrees of (in)compatibility between their instruction sets:

http://en.wikipedia.org/wiki/List_of_ARM_microprocessor_cores

For example, our Astrobe Oberon ARM compiler targets both ARM7TDMI devices (ARMv4T architecture) and Cortex-M3 devices (ARMv7-M architecture). The Raspberry uses an ARM11 device (ARMv6-architecture).

Peter Mathias has already done some work on a port of ARM Oberon to Linux for the Raspberry Pi. However, the last I heard he had been stalled by problems with the dynamic linker:

There have been a few discussions on the Oberon mailing list e.g.
