At the Octave conference in Geneva the presentation Support of free software in public institutions: the KiCad case will be given by Javier Serrano and Tomasz Wlostowski from CERN.
KiCad is a tool to help electronics designers develop Printed Circuit Boards (PCB). CERN's BE-CO-HT section has been contributing to its development since 2011. These efforts are framed in the context of CERN's activities regarding Open Source Hardware (OSHW), and are meant to provide an environment where design files for electronics can be shared in an efficient way, without the hurdles imposed by the use of proprietary formats.
The talk will start by providing some context about OSHW and the importance of using Free Software tools for sharing design files. We will then move on to a short KiCad tutorial, and finish with some considerations about the role public institutions can play in developing and fostering the use of Free Software, and whether some of the KiCad experience can apply in other contexts.
We have just released v4.0 of the WR PTP Core. You can find all the links to download the reference designs binaries and user manual on our release wiki pageThe main features and fixes you will find in this release include:
- Re-written, debugged and simplified Mini-NIC
- Improved synthesis time with RAM initialization
- New platform and board HDL support packages
- SNMP and Syslog for remote diagnostics
- VLAN support
- fixed 64-bit printouts for long WR links
- option to use P2P PTP mode
- bugfixes and documentation expanded to describe also the HDL ports and generics
Thank you for all the bug reports and contributions. As always, we encourage you to try this fresh release on your boards.

Furthermore another, more general HDL developer job is opened:
A poster of the GEFE project has been displayed during the RADiation Effects on Components & Systems (RADECS) 2016 conference, held at Bremen from 19/09/16 to 23/09/16.
The poster can be downloaded from the "DOCUMENTS" section of this site.
The results of the radiation test performed to the GEFE v2 at the CHARM facility at CERN have been presented during the Radiation Working Group (RadWG) meeting on the 07/07/16 at CERN
The slides of the presentation can be downloaded from the "DOCUMENTS" section of this site.
The new stable release v5.0 of the WR Switch firmware comes this year as a Christmas present. As always, you can find all the links to download the firmware binaries and manuals on our release wiki page
Main features and fixes include:
- Updated Buildroot 2016.02
- Updated Linux kernel 3.16.38
- Fixes to the SNMP support preventing it from crashing or not updating objects
- Changing WR interfaces enumeration in Linux (wri1..18 instead of wr0..17) to match the ports enumeration on the front panel
- 64-bit Tx/Rx frame counters
- Verification of firmware checksum before updating
- VLANs configuration in the central dot-config file
- make menuconfig on the switch to facilitate modification of a local dot-config file
- New timing role none to disable PTP on selected ports
- More verbose Syslog messages in case of errors
- new wr_mon tool - with improvements for reporting VLANs and synchronization peer
- User-defined boot script execution for all exotic setups currently not possible with standard configuration mechanisms
- Tools for reading and writing SFP EEPROMs
- Advanced RTU configurations in dot-config
- Re-written, more efficient multiport linked list in the switching core
- Added bandwidth throttling HDL module to prevent CPU from being flooded with traffic from WR ports
- Additional frames counter for traffic originated from Linux to WR ports
- Improved RTU forwarding decisions to save resources and not forward Ethernet frames to ports that are down
- White Rabbit Switch: Failures and Diagnostics - document that lists various errors that the switch may report and tries to propose possible problems that caused the Error and actions that should be taken.
Thank you for all the bug reports and contributions. As always, we encourage you to try this fresh release on your switches.

Andrea Borga from NIKHEF has presented High Energy Physics and Open Source engineering, accelerate shared knowledge at OSSHC 2016, the first edition of the yearly Open Source Software en Hardware Congres for the Benelux countries.
All the presentations (some in Dutch) can be found under the Tab Downloads.
Javier Serrano will give a Keynote presentation at the PCaPAC conference.
Open Source Hardware (OSHW) follows the lead of Free and Open Source Software (FOSS) and has similar goals: ensuring developers can share their work without artificial hurdles, improving quality through peer review, avoiding vendor lock-in and providing for a fair playground in which projects can thrive and accommodate contributions without compromising their long-term future. The talk will introduce OSHW and then attempt to answer a number of questions:
•What are the perceived benefits and issues of OSHW, in general and in the context of public research facilities?
•What is new with respect to FOSS?
•What makes OSHW projects succeed or fail?
The talk will use real examples of OSHW projects throughout, and will conclude with some thoughts about what the future holds in this domain.
The 11th International Workshop Personal Computers and Particle Accelerator Controls 2016 (PCaPAC) will be held by LNLS, in Campinas, Brazil. PCaPAC traditionally focuses on low-cost control systems using PC technology for control & data acquisition systems and emerging technologies.
In his message KiCad: A commitment to freedom, Javier Serrano thanks the KiCad supporters for their generous donations through the CERN & Society Foundation.
DCES will be presented in at CHEP 2016 in San Francisco during the poster session.
