Re: [oshug] OSHCamp 2019 (31st Aug & 1st Sept), call for Talks & Workshops.
by Andrew Back 28 Mar '19

28 Mar '19

Hi All, Just to note that the call deadline has been extended to Monday 29th April at 17:00. However, if you are thinking of giving a talk or hosting a workshop, it would be appreciated if you could submit details or get in touch sooner, where possible. Also appears as though my previous message to oshug@ didn't make it into the archives, so I'm not sure if it was received? Although the post to oshug-announce@ did. Will look into this.

OSHUG #72 — Open Source FPGA Hardware and Tooling Past, Present and Future, Thurs 21st March.
by Andrew Back 12 Mar '19

12 Mar '19

Hi All, Registration is now open for the 72nd meeting, which is being held in partnership with the BCS OSSG. Details below. Also a reminder that the OSHCamp 2019 call closes in a little under a month, on Monday 8th April! Still plenty of opportunity to submit talk and workshop proposals and there is an online form at: https://docs.google.com/forms/d/1Bd2FHzkjehF-7zD386xbJ1ujrVcWWPoe_As1WOYnrQ… Any questions don't hesitate to get in touch. Cheers, Andrew // Event #72 — Open Source FPGA Hardware and Tooling Past, Present and Future. On 21 March 2019, 18:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/72 Once upon a time we could only use proprietary tools and development boards supplied by FPGA vendors. This all changed in 2016 with the advent of the IceStorm open source toolchain, combined with open hardware like the myStorm board. With the 2nd generation of tools and hardware, sophisticated FPGA features are opening exciting avenues for 'open source all the way down'. We hope to provide an update and crystal ball on where some of this could be leading to. — Tools: past to present David Shah looks at where we have come from with the IceStorm toochain, and looks at how this has developed recently and expanded Lattice iCE40 support to include new lower power, lower cost, reduced pin count FPGAs to include their Ultra & Ultra Plus range. — Hardware: past to present Alan Wood talks about the journey through the early history of open source FPGA open hardware from IcoBoard through myStorm too recent UltraPlus offerings recently made available. — Tools: present to future IceStorm was aimed at a narrow family of iCE40 FPGAS, the new SymbiFlow family of tools expands the open source tooling exponentially. David Shah takes a look at NextPNR, which lies at the heart of the toolset and deals with specific FPGA family functionality, in particular he concentrates on the Lattice ECP5 family support he has developed with Project Trellis as part of NextPNR and the recent 1.0 version supporting this new family and high end FPGA features. — Hardware: present to future What comes next for open source FPGA hardware, after the success of tinyFPGA and myStorm we are beginning to see ECP5 open source hardware emerging, first with Radiona's ULX3S and being followed up by offerings from both tinyFPGA and myStorm dev board stables. With new hardware comes new features building on NextPNRs tooling, like DSP, SerDES I/O gearing and DDR memory etc. Alan plots the course for these new powerful opesource development boards. — Demos Time permitting we can show some of what's possible with the new tools in a brave new 'open source all the way down' world. * David Shah is a engineer at Symbiotic EDA and a Electronic and Information Engineering student at Imperial College London. He entered the world of open source FPGAs by extending Project Icestorm, the iCE40 bitstream documentation project, to include the newer iCE40 UltraPlus FPGAs. As well developing Project Trellis, he has been involved in the development of a new open source FPGA place-and-route tool, nextpnr. * Alan Wood has been working with parallel distributed programming for several decades. His recent work includes smart grids, 3D printers, robotics, automation, biotec diagnostics and designing FPGA dev boards. His current research is focused on machine learning for embedded automation using FPGAs. He is a long term advocate of open source communities, a moderator (aka Folknology) for xCORE, the co-founder of myStorm open hardware FPGA community, as well as a co-founder of Surrey and Hampshire Makerspace. Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt. -- Andrew Back http://abopen.com

Open Source Infrastructure Conference
by Danny Abukalam 13 Feb '19

13 Feb '19

Hello, I've recently discovered OSHUG after I was pointed at it by a colleague. I am aware of the Hardware Camps at Wuthering Bytes, but didn't realise this was their home! I hope it's OK to post such a message to this list... I thought I'd send a message to let you guys know about a non-profit community-driven event that we're running in Central London on April 1 & 2 2019. The focus is all things open source infrastructure, and is an evolution of OpenStack Days, opening out to a lot more topics and tracks including open hardware. The Open Compute Project is a backing foundation of the event, and we're going to have a track on Open Hardware in the datacentre. You can find more information on the conference and workshops here - https://openinfradays.co.uk/. We're accepting talk proposals up until Feb 28th, so if you'd like to submit something it would be more than welcome! Thanks, Danny

OSHUG #71 — Machines and systems of past, present, future, Thurs 17th January.
by Andrew Back 16 Jan '19

16 Jan '19

Hi All, Registration is now open for the 71st meeting, held in partnership with the BCS OSSG. Details below. Cheers, Andrew // Event #71 — Machines and systems of past, present, future On the 17 January 2019, 18:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. http://oshug.org/event/71 To start off the year, we have a series of talks around the theme of Acorn computers, RISC OS, RISC-V toolchain. This is a joint meeting with the British Computer Society Open Source Specialist Group. — Brief history of Unix-like operating systems on Acorn hardware Stephen Borrill first encountered Unix while working for a PhD in Psychoacoustics and as a long-term Acorn user, his Acorn RiscPC was his hardware of choice to run it on. While finishing his PhD, Stephen started a part-time job at Acorn Computers working in technical support. This led to full-time employment at Acorn and Xemplar (an Acorn and Apple joint venture focussed on UK education) during which he developed products based on BSD Unix on Acorn hardware which were sold nationally. In 1999 Stephen founded Precedence Technologies who took over support and development of the products he worked on at Acorn and Xemplar. He continues to with the products 20 years later. — RISC OS : What's Next As of 2018, RISC OS is an open source operating system. This talk will cover the heritage of RISC OS, direction it would like to go, the response since it was open sourced as well as a demo of the latest computers that run RISC OS. * Richard Brown is a co-founder and director of RISC OS Developments Ltd. Since its inception in April 2017, Richard has been a driving force in making RISC OS truly open source; this was achieved with significant funding and community support in November 2018. Richard is also the sole director of GeneSys Developments Ltd, an IT company, which additionally incorporates Orpheus Internet, an ISP company. Despite not having a 'techie' background, Richard would end up assisting or implementing IT solutions for the companies he worked for. Taking the opportunity to further his technical knowledge and experience, Richard went on to work in the IT industry and set up his own business in 1995. In the early 80's, Richard spent some time in Canada. Here, he worked in the camera industry where he acquired advanced skills in photography, a love of which had been instilled in Richard as a young person by his father and continues to be a key skill in his career to date. — Embedded FreeBSD on a five-core RISC-V processor using LLVM We were tasked with bringing up and testing embedded FreeBSD on a custom five-core 32/64-bit RISC-V processor using LLVM. Given FreeBSD has already been ported to RISC-V and LLVM is the standard BSD C/C++ compiler surely this should be easy. But it wasn't. LLVM for RISC-V is still relatively immature, particularly for 64-bit. FreeBSD runs on symmetric multi-core 64-bit QEMU RISC-V, but not on embedded systems and not on heterogeneous multicore systems. In this talk we'll go through the steps needed to bring up a functioning embedded FreeBSD system on multi-core heterogeneous RISC-V system. Our target hardware was not available at the start of the project, so we used the generally available HiFive Freedom Unleashed board. The result is a reference embedded FreeBSD implementation for RISC-V, freely available to the community. This is not a talk about the deep internals of FreeBSD, but about the practical engineering steps needed to bring up an embedded operating system where many of the key components are not yet fully mature. * Jeremy Bennett is Chief Executive of Embecosm, a company developing open source compiler tool chains and porting embedded operating systems for new architectures. He is author of the standard text book "Introduction to Compiling Techniques" (McGraw-Hill 1990, 1995, 2003) and is an active member of the RISC-V Compliance Task Group. — Buildroot for RISC-V (Using Buildroot to create embedded Linux systems for 64-bit RISC-V) Buildroot is an embedded Linux build system that generates complete system images from source for a wide range of boards and processors. I have recently added support for 64-bit RISC-V to the official Buildroot distribution which make it a viable alternative to other build systems for RISC-V such as Yocto. During this presentation I will give a brief overview of Buildroot and how it compares to Yocto for those in the audience who are unfamiliar with these systems. In the main part of the talk I will look at the issues relating to the implementation of RISC-V support, based on my experiences. This will include a look at the status of the RISC-V software ecosystem with regard to the selection of a suitable toolchain, C library, kernel and bootloader. I will then run through how to configure and build a minimal system for booting under QEMU. Finally I will consider any further work required to improve Buildroot for RISC-V including the status of 32-bit support. * Mark Corbin is Embedded Operating Systems Lead at Embecosm. He has an extensive background in embedded systems development and has worked with Linux since 1996. He specialises in building embedded Linux distributions and is currently the RISC-V maintainer for the Buildroot project. Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt. -- Andrew Back http://abopen.com

What happened to RepRap?; TFMS looking to buy Huxley Duos
by J. R. Haigh 13 Jan '19

13 Jan '19

Hi, We at the Telford Makerspace (https://TelfordMaker.space ) are looking to get 2 or 3 RepRaps (https://RepRap.org ) with which to run workshops. We decided on getting a couple of RepRap Huxley Duos (https://web.Archive.org/web/20160620213955/http://RepRapPro.com/documentati… ), and materials and parts to build at least another Huxley Duo. Features of the Huxley Duo which appeal to us are: > • OSH and well-documented; > • Cartesian-style filament printer; > • dual-filament; > • small and portable with a very sturdy frame; > • cheap – 750£ will buy at least 3 of them; > • repairable; interchangeable; modifyable; upgradable. However, Andy D'Arcy Jewell and I could not find finer details such as nozzle diameter or print resolution, and when we were looking to buy one, we found that all of the links that we tried are dead or discontinued, i.e. we could not find /any/ live link to a current retailer of the Huxley Duo. The RepRap Project somewhat feels like a ghost town. We'd like to know: • Why did RepRap Ltd. close? • What happened to the RepRap Project and its community? • Where we can get RepRap Huxley Duos and their parts from? I notice that there's a fairly recent email to the list, the one announcing the 68th OSHUG meeting, that suggests that RepRap is still current without any hint of demise: At 2018-07-10Tue21:58:59+01, Andrew Back sent: > […] > Yet engineering hasn't worked with the power of self replication much, if at all, until now. This talk will be about the RepRap Project - an open-source project that has created humanity's first general-purpose self-replicating manufacturing machine. It will examine the likely social and economic impacts of self-replicating technology, and draw parallels with a twelve-thousand-year-old industry that uses natural self-replicating machines, the industry without which we would all starve: farming. > > * Adrian Bowyer holds a first degree and a PhD in engineering from Imperial College. He was an academic engineer and mathematician at the University of Bath for 35 years, from where he retired in 2012 to become a director of RepRap Ltd., a company that sells RepRap machines and components, and that undertakes research and consultancy in RepRap-related projects. RepRap Ltd is an entirely open-source company, and all its designs, software and documentation are freely available to everyone. […] The present tense implies that RepRap is still current. I sincerely hope so. Best regards, James R. Haigh. -- Wealth doesn't bring happiness, but poverty brings sadness. https://wiki.FSFE.org/Fellows/JRHaigh Sent from NixOS with Claws Mail, using email subaddressing as an alternative to error-prone heuristical spam filtering.
