NetBSD/acorn32 is a port to ARM- and StrongARM-powered Acorn RiscPC
compatible machines and is maintained by
Reinoud Zandijk (
The first formal release of NetBSD/acorn32 is 1.6.
In earlier releases of NetBSD, these machines are supported by
The port first saw light as RiscBSD in 1994 and was later transformed
into NetBSD/arm32. In 2001,
the arm32 port was split into separate ports for the various supported
hardware types. NetBSD/acorn32 was one of these.
NetBSD/acorn32's booter manpage submitted
Reinoud has finally added the manpage boot(8)
for the bootloader. The current bootloader version is v3.10 in CVS.
Substantial rewrite of vidcaudio driver
Ben Harris has largely rewritten the vidcaudio driver, adding support
for 16-bit audio on the ARM7500/ARM7500FE and generally making it work
arm port Xscale optimizations
Steve Woodford announced that he has committed various Xscale
micro-optimizations to the NetBSD/arm ports.
Please see his message
to the port-arm Mailing List for details.
The FAQ has been updated and been actualised.
Added is the question how to boot an NC into NetBSD using the new boot32
Bootloader v3.01 has been released for testing
The acorn32 portmaster Reinoud Zandijk has released version 3.01 of
the bootloader. This new bootloader is a complete rewrite and comes as a
NetBSD compileable single RISC OS relocatable module and is capable of
booting all supported machines including NC's. It's still in development
but ought to work fine for all users. You can download the latest released
version of the module boot32
and give it a try. Please report problems to the mailing list or to the
Archive of NetBSD/acorn32 news items
Supported Computer Systems
These are systems made by various computer manufacturers for which
support as a whole exists.
Earlier ARM-based Acorn machines are supported by
Core processor support was written by Mark Brinicombe (most of
it) and Neil Carson (some of libkern and pmap, floating point
emulators and libraries).
Support for Acorn platforms was written by Mark Brinicombe (most
of it) with help from Scott Stevens (various device drivers),
Melvin Tang Richardson (VIDC console), Mike Pumford (EtherH driver)
and Andrew McMurry (Acorn FileCore filing system).
