ARM Ltd. FPEmulator sources published

Posted by Steve Revill Wed, 26 May 2010 17:25:00 GMT

RISC OS Open (ROOL) are pleased to announce the immediate release of source code supplied by ARM Ltd. (ARM). This source code has been published as Open Source software under the New BSD licence and it comprises the FPA support code (FPASC) and emulator (FPE).

The FPE is a key part of the RISC OS operating system and as such the availability of these components in source form is a key step towards completing the publishing of the full sources to RISC OS. You can find the new FPASC source code within the ROOL CVS repository as part of the FPEmulator module.

Until now, the FPASC and FPE have only been available to the public in binary form. This is equally true for other operating systems, such as the BSD derivatives. ROOL will be contacting the maintainers of various ARM BSD projects in due course.

Note to editors: this press release does not constitute an endorsement of RISC OS or of the FPE by ARM.

Updates on the ROOL website

Posted by Steve Revill Fri, 02 Oct 2009 13:51:00 GMT

In advance of the London Show this weekend, RISC OS Open have updated a large number of the downloads to the latest and greatest versions.

All of the source code archives are automatically updated each night but prebuilt items, such as ROM images and applications, are only updated when we perform builds.

To assist with the on-going work on the Beagleboard, all of our pre-built components are now ARMv7 safe and the OMAP ROM build is up to date. We’ve updated the RISC OS 5.15 ROM build (for IYONIX softload) to use the latest sources in CVS, too.
