Bear Metal's repositories

PDP-11

This project contains scripts to build a PDP-11 bare metal GCC version 13 cross compiler, and a simple bare metal shell for a PDP-11.

Language:CNOASSERTION1 10

bmomp

Bare Metal OpenMP: running OpenMP on bare metal microprocessors with no operating system. (This project is slightly stale, see H503 instead).

Language:C++BSD-3-Clause010

Crosstool-ng .config files to build bare metal GCC cross compilers for various hosts and targets. These compilers are built using a modified crosstool-ng which enables OpenMP for bare metal (see https://github.com/jrengdahl/crosstool-ng-openmp).

crosstool-ng-openmp

Minor modifications to crosstool-ng which enable OpenMP in bare metal GCC compilers.

Language:ShellNOASSERTION010

H503

Test firmware and OSHPark board for STM32H503RB, including USB VCP console. Working toward bare metal OpenMP.

Language:CNOASSERTION000

HowTo

This is a collection of README files that help me remember how to do various tasks that occur so infrequently that I need help remembering how to do them.

000

lisp

A simple Lisp interpreter, originally written in 68000 assembly code and released for the Amiga in 1987 on BIX. I'm working on translating it to C++.

MSCP

This project includes a KiCAD board design and firmware intended to become an MSCP SSD for Qbus PDP-11 computers.

Language:CNOASSERTION000

u-boot

A fork of "Das U-Boot" which runs from ARM Cortex-M7 (STM32H743) on-chip flash and RAM
