Another success: PCB completely financed! It’s time for the prototypes campaign!

Thanks to the kind contribution of the donors, we just reached the goal of the campaign for financing Phase 1B “Fast simulation bus”.

The PCB (Printed Circuit Board) design is currently being finalized, as soon as we have reviewed it, we will publish it in our GitLab repository. This last phase was of fundamental importance as we could test the correctness of the design, paving the way for the next campaign.

We got through the hardest parts with regards to the Research and Development choices. We past the uncertain ground with its many open challenges and many solutions have been explored. We also past the economical goal of previous campaigns that were quite heavy, and thanks to many people we have managed to get this far, again, thank you all!

We are now ready to launch Phase 2 “Production and delivery of five working prototypes” with a goal of 10500 Euros (around 12720 USD).

  1. Slimbook Eclipse Notebook

    Donation Campaign for Production of five working Prototypes

    €1,777.00 donated of €10,500.00 goal

Our target is to complete this new campaign by Spring 2021, and we are working again with the patient guys at ACube Systems that will assist us in making the five prototypes.

These prototypes will be very important as they will be used to

  • put the PCB design to the test
  • learn how to correctly initialize the hardware
  • fine-tune the configuration of U-Boot
  • fit the motherboard in the Eclipse Slimbook body

So far, we worked with U-Boot on the NXP T2080 RDB Devkit but that is quite different to our motherboard, which is quite more complex. We have to fine-tune U-Boot directly on the final hardware, and the prototypes will be essential for this. In addition, work on U-Uoot is still required even with the Devkit in order to correctly set up the framebuffer. Right now we can access the U-Boot console in serial mode only. ACube Systems will assist us on this task.

The motherboard is designed (screw and ports positions) to fit inside the Eclipse Notebook body that the prototypes should be mounted on.

Moreover, we need to redesign the dissipation heat pipes that will be slightly different from what was originally in place for the Eclipse Notebook.

Maybe some of you didn’t even think it was possible but we are progressing. The journey is still not finished. We need you to tell about this project all around you as we need more interested people, more donations.

2021 is our year! Let’s make this project a reality!

PCB Design nearly complete, preparing for the next campaign aimed at working prototypes

The campaign aimed at the “Fast simulations bus” is nearly complete, and we will receive the resulting PCB design before the end of 2020. As soon as we have reviewed it, we will publish it in our GitLab repository. Here a screenshot with the PCB design currently being finalized.

Similarly to what we did for the current campaign, the next donation campaign for financing the “Production of five working prototypes” will start as soon as the current campaign will reach its end. In coordination with ACube Systems, we fixed the cost of the five prototypes to 10.500 euros, and we aim at delivering them during late Spring 2021.

Freedesktop-sdk for PPC64 Big Endian Compiled!

We have patched freedeskop-sdk to compile perfectly on PPC64 so now we are preparing, according with Freedesktop-sdk teams, the merge requests to send to the mainline repository.

So we have successfully compiled 432 packages that it involves even the last version of go lang.

We thanks OSU Open Source Lab and OpenPower Foundation to provide us a Power9 VM with 8 cores and 16GB of RAM that permit us to compile Freedesktop-sdk for PPC64.

Now thanks to [email protected] we have a Power8 VM to recompile freedesktop-sdk for PPC64 in Continuous Integration for gitlab freedesktop-sdk pipeline.

As Flatpak binary is running on Debian 10 PPC64 Big Endian and need the Freedesktop-dsk layer to prepare the flatpak packages starting from hundreds of manifests, now we are a step closer to see flatpak packages prepared for PPC64 .

PPC64 Open ISA and A2I Core along with the PPC64 Open Hardware Notebook PCB and Libre-Soc project.

This year IBM released the A2I POWER processor core design and associated FPGA environment. In 2019 IBM opened the POWER Instruction Set Architecture (ISA). The Power Progress Community released the PCB of the Notebook Motherboard based on Power Architecture with Cern Open Hardware License. Libre-SOC is a software-hardware project that aims to deliver a physical POWER compliant SOC that comes complete with a CPU, GPU, VPU, and DDR controller. We will discover these concrete projects

Video: our Speak at OpenPOWER Summit NA 15 Sept 2020

On 15th September 2020 at OpenPOWER Summit NA, there was many interesting speaks and projects, our speak

Around 6 years back, we started as a group of FOSS, PowerPC and Open Hardware enthusiasts, with beginning to work on PowerPC Notebook project which was designed around GNU/Linux using Open Hardware. We had very limited funding with limited skills to work. But our enthusiasm and motivation led us to reach fabrication stage for the motherboard. Finally this year we could successfully design its PCB with the help of collaborators and limited funding from donors. There were many challenges faced in this process. Since PowerPC processors have been around for more than 2 decades, but the current implementation on Notebook was difficult to take in the market. Coming to the performance in Big Endian mode is maximized in this with many software need to be patched. In future we plan to upgrade our PCB design to the more recent packaging technology for the processor. Also, with increasing collaborators, it would be possible to design more smaller and cheaper PowerPC board.

Our Speech at Open Source Summit. 15 days to donate 2600 euro left.

Our PPC64 Motherboard Board Design

The tentative deadline for Phase1B is 18th November so there are two weeks left to donate the remaining 2600 euros. If we will reach the goal, the PCB with SI bus simulation should be ready by the middle of December.

In this case in before the end of 2020 we start working on production of the Prototypes together with the Prototypes Donation Campaign.

We have to give a name to the motherboard, suggestions still remain open few days more on our forum.

Our Open Hardware license and endianness suggestions at OSS 2020

We have talked about Cern Open Hardware License and Endianness at Open Source Summit + Embedded Linux Conference on Europe 27 Oct 2020

Cern Open Hardware License

Why not a software license such as GPL?
Hardware licenses are specific for hardware so they are written using the appropriate words: manufacturer, devices, CAD tool…

Why we choose the CERN Open Hardware Licence v1.2?
We think it offers a better protection for the licensor compared to other hw licenses such as TAPR Open Hardware License

So, who are the licensor and the licensee?
– In our project we (Power Progress Community) are the licensor and the licensee is the hardware producer.
The Licensee may manufacture or distribute Products
– Licensee could modify our work but the modification must be available under the same or equivalent license.
Licensor is protected
– Quality and responsabilities of the hardware belong to the licensee.

Other important notes
– Firmware, drivers and any other software would require their own license.
– Intellectual property belongs to the licensor.
– Documentation must be provided in the right format to be modified (using a CAD tool).

Eureka! Here we have the Board layout! 15 days to donate 3660 euro left.

We are happy to share to all the donors and followers the Board Layout of our PPC64 Notebook Motherboard!!!

The design of our board layout is meant to fit inside the Slimbook Eclipse body. The PCB Design which is currently being worked on using Mentor Xpedition.

In September 2020 we have published on our gitlab repository the Orcad source file with the latest version (v0.6) of the Electrical Schematics, you can go more deep on these board layout starting from the Orcad source.

The tentative deadline for Phase1B is 2th November so there are two weeks left to donate the remaining 3660 euros. If we will reach the goal, the PCB with SI bus simulation should be ready by the end of November.

In this case in December 2020 we will work on production of the Prototypes together with the Prototypes Donation Campaign.

Orcad source of Electrical Schematic v0.6 published and other news

Finally we have published on our gitlab repository the Orcad source file with the latest version (v0.6) of the Electrical Schematics.

This file is at base of the PCB Design which is currently being worked on using Mentor Xpedition. The previous version of the schematics required some updates in order to accommodate minor changes to match the Slimbook chassis internal spaces. In addition, the schematics are now compatible with the I/O expansion board and the position of the external ports found on the “Elipse” chassis model, that was kindly provided by Slimbook.

After achieving the goal of Phase 1A (thank you all!!), we have just started Phase 1B of the donation campaign targeting the “Fast SI bus simulations”, in other words, an in-depth analysis of the integrity of signals of the PCB that came out from the previous campaign.

After discussing with the engineers currently working on the PCB, we were told that publishing an incomplete and potentially buggy PCB does not have much sense, as there might be major problems that will be solved after carrying out the SI bus simulations. At the end of these long discussions, we agreed on publishing the PCB only after reaching the end of Phase 1B, when all checks will be done.

At this point we cannot fix a deadline for publishing the PCB, as the end of the work on the PCB largely depends on when we will reach the goal of Phase 1B donation campaign and when the SI simulation will help solve all electrical problems that may come up.

The tentative deadline for Phase1B is 16th October so there are two weeks left to donate the remaining 4000 euros (around 4700 USD). If we will reach the goal, the PCB with SI bus simulation should be ready by the end of November .

This new campaign (Phase 1B) aims at the “Fast SI bus simulations”, in other words, it will pay for an in-depth analysis of the integrity of signals of the PCB that came out from the previous campaign. We have started the collection of donations right after reaching the 100% of the previous campaign.

The PCB Design , designed with Mentor Xpedition that came out from the previous campaign will be published here soon, a first public draft should be ready by the end of September.

After the in-depth analysis of the integrity of signals of the PCB will be performed, thanks to the current Donation Campaign, an updated version of the PCB will be published.
