Progress on PCB Design and on Software

Updates on Schematics are being transposed to the PCB design

In February the designer analyzed the Pericom PI7C9X2G608GP PCIe Packet Switch with the direct support of Pericom staff. Now, the Pericom PCIe Packet Switch is fully tested and all the needed setup is completed, so the designer has completed the inclusion of  all required information in the updated version of the schematics and is starting to unravel the PCB. 

The designer has updated the SerDes connections following our suggestions taking into account the notes we have provided, so a new version of the schematics is expected soon.

Arctic-Fox 27.10.1 PPC64 in our Repo

The main contributor to Arctic-Fox – Riccardo Mottola – member of our Power Progress Community association – has released the new version 27.10.1+b0 that we have compiled and packaged in our Debian PPC64 repo. Riccardo says: “Session Store, code greatly improved compared to past releases, performance improvements in both the html engine as well as a new build system imported from Firefox. This release is definitely a great improvement compared to 27.9.19 right at start”

Arctic-Fox 27.10.1 PPC64 running on our T2080-RDB, that has the same processor as our future notebook.

Repository moved to our Power Progress Community GitLab group.

We have created a Gitlab group called Power Progress Community and we moved all our gitlab repositories under https://gitlab.com/power-progress-community. What is important to know is that all URLs have changed and any cloned repository must be rebased. If you have cloned our repositories you should update git remote origin.

Working on Unreal Engine for PowerPC64 Big Endian

We are working on a port of UnrealEngine (UE) to PowerPC 64 Big Endian. We started by forking the PowerPC64 Little Endian (PPC64le) version and we are currently trying to compile the sources. The original PPC64le port for UE 4.23 was developed by Elvis Dowson and Raptor Engineering and can be found at https://github.com/edowson/UnrealEngine/tree/4.23-ppc64le. Access to the UE4 sources requires accepting the Epic Games EULA as described in https://www.unrealengine.com/en-US/ue4-on-github.

We have  modified the original scripts to compile for PPC64 Big Endian but so far, we still have to solve multiple errors leading before being able to generate a working binary. You can find our fork and ppc64 branch here https://github.com/robyinno/UnrealEngine/tree/4.23-ppc64 ( to access it you need to accept Epic Games EULA). We are building the source using both a Power9 virtual machine provided by Open OSU and OpenPower Foundation, as well as on our NXP T2080-RDB development kit using Debian PPC64 SID unstable. If you want to help us on fixing the compilation errors, you can start from our UnrealEnginePPC64 Wiki, please contact us.

PCB design updates and updated components list

As we stated in a previous article, we have already contracted ACube Systems and the PCB design work has started. This post is a first report about the work in progress in relation to the PCB design.

These days, the designer is analyzing the Pericom Switch with the direct support of Pericom personnel.

The Pericom PI7C9X2G608GP is a PCIE Gen 2 Switch that provides one upstream port supporting x4 or x1, and 4 or 5 downstream ports that support x1 operation. This chip has a Power Dissipation of 1.2 W.

In our mobo the PI7C9X2G608GP is essential as it allows to connect one 4x PCIe 2.0 controller of the NXP T2080 CPU with four 1x PCIe chips/cards: M.2 3G/LTE card , M.2 WiFi card, 1x Renesas USB3 Controller and 1x C-Media Audio chipset.

PCB Design Started! Carpe Diem!

Four months have passed since we started our donation campaign aimed at the PCB design and we are now at around €6500 (27%) of the goal €24000 for the entire phase 1 of the design, and we must admit that the rate of donations is slower than what we had hoped for.

Phase 1 is subdivided in two subtasks:

  • 1A) PCB Project € 19000
  • 1B) Fast SI bus simulations €5000

In other words, we reached an encouraging 34% of what is required for subtask 1A.

As we really want to speed up as much as possible the activity, we decided to formally split phase 1, and not to wait to reach €24000 to start the design of the PCB.

To do so, we signed a contract with ACube Systems (company we rely on for the design) just for subtask 1A. Doing so gives the chance to start right now the PCB design. At the time of signing the contract, we paid €6000, the amount required by the designer to start working.

Slimbook Eclipse Notebook

One of the reasons forcing us to speed up the planned activities, is linked to the availability of the Slimbook model “Eclipse” that will not last forever, very much like any other commercially available products such as the electronic components we selected during the electrical schematics design phase. In fact, the electrical schematics are customized for the pinouts of that specific Slimbook model, and the PCB design will be specifically shaped to fit in the Slimbook Eclipse chassis. Because of these constraints, we have to finish the PCB design (phase 1A), the fast SI bus simulations (phase 1B) and the prototypes (phase 2) around this summer.

We fixed the end of April 2020 as the time-limit for phase 1A, so we have 3 months left to raise the remaining €12500. As you may well understand this goal is quite ambitious, but it is necessary if we don’t want to risk to fail.

PCB for a Happy New Year!

Orcad Source Schematics Published

At the end of August of 2019 we published the first version of the schematics in pdf format. Then, in October we uploaded the second version and after that the 13th of November we released the Orcad source, accomplishing what we promised.

Schematics Source in EDIF published and ready to be converted to KiCad

Now we have exported it even to EDIF format, to make easier for new volunteers to convert it to Kicad Format. To convert from EDIF to Kicad we have found edif2kicad tools  https://github.com/svn2github/edif2kicad but we are sure you will find other tools or even you will be able to create a new one

European Presentations – Autumn 2019

25th October Valencia – Spain

Guillermo is updating about our project on 25h October 2019 at GNU/Linux Valencia Group

For the second time we were giving a talk to the GNU/Linux Valencia Group, a local Linux group located in the city of Valencia, Spain, which is doing a great job promoting Linux and open source in general. Guillermo gave a brief explanation of the project from the beginning to the present, the objectives, technical specifications, other related projects of the Power Progress Community association, FAQs about the project and so on.

In particular the group was updated about everything that has occurred in the project since the last time we visited them. One of the key points was the collaboration with Slimbook, this collaboration started just because of last year meeting with the group as this company is located at the same city and his CEO is one of the founders of this Valencian group. The company will provide the  laptop body and is supporting our team giving all specifications we need.

You can find an article covering this meeting in the GNU/Linux Valencia group page (in Spanish):

Donation Campaign for PCB design of the PowerPC Notebook motherboard

  1. render powerpc notebook

    Donation Campaign for PCB design of the PowerPC Notebook motherboard

    €9,106.16 donated of €19,000.00 goal

Open Hardware release of the Printed Circuit Board (PCB) design for the motherboard of the GNU/Linux PowerPC Notebook.

The initial 2,703 euro of donations of this campaign arrive most from recurring donations that continue to arrive from the old campaign after reached the old campaign goal.

In short:

Our hardware group identified in early 2017 a desirable list of components and a set of features of the laptop. In June 2017 we launched a first donation campaign that was aimed at paying ACube to design the electrical schematics and a year later, in June 2018 we reached the goal of collecting €12,600 and finally started finalizing the design. Here you may download the resulting schematics of the 1st donation campaign.

As of today, the notebook specifications are the following (subject to change):

    Donation Campaign for PCB design of the PowerPC Notebook motherboard

    €9,106.16 donated of €19,000.00 goal

Few days ago we announced that Slimbook will provide the enclosure we need for our Open Hardware PowerPC notebook. In addition to that, we have published in our repository the pdf containing the new version of the schematics. Further updates will arrive during the following days ( the Orcad source files will be available during October)

Slimbook to provide the notebook chassis

One of the main points when you are designing a laptop is the relationship between the motherboard and the enclosure. It is not a good idea to design the motherboard if you don’t have the chassis. At the same time, the enclosure has to take into account how the motherboard will be.

Now we are happy to announce that Slimbook will provide the enclosure we need for our Open Hardware PowerPC notebook. ACube and Slimbook are collaborating since the beginning of this year, exchanging information about components disposition and pinouts, thermal dissipation and so on. 

ACube is a well known company with experience in creating PowerPC computers including  Sam460ex and Sam460cr motherboards or the AmigaOne 500 desktop system.

Slimbook is having a great success selling their own Linux laptops (such as the ProX) and mini PCs world-wide.

Due to this collaboration we have almost everything we need to achieve our goal in terms of technology. 

Electrical Schematics final version

We want to update you that first days of October we will publish in our repository the pdf containing the final version of the schematics. After that, during October,  the Orca source will be available as well, tailored for the Slimbook chassis. This means that the design of the PCB will fit inside the Slimbook chassis.

In case you are able to convert Orca source to Kicad you are welcome to do it. If you have any issue when doing so, contact us and we will be happy to provide some help.

New ppc64 applications in our repo

Lastly, we have patched the following applications for ppc64 (Big Endian) : arcticfox, palemoon, mame, fs-uae, libx265, qemu, midori.  They run on PowerMac/ImacG5 ( Power4 processor) but also on more recent Big Endian ppc64 processors such as NXP T2xxx and T4xxx.

We are also working on many other complex applications like Blender that require the creation of dedicated groups for the distribution of the necessary effort.

We’re performing tests, reporting bugs and suggesting workarounds to complete the installation of Debian 10.0 using ISOs released by the maintainers of Debian ports for ppc64be.

If you want to join the software workgroup and help these software tasks feel free to contact us.

C-Media supports our Open Source PowerPC design

We announce the cooperation with C-Media. C-Media is a global leading audio IC/software solution provider.

https://www.flickr.com/photos/zenmama/13930451071/

In this post we want to explain one of our latest achievements. During the present year we have been looking for an audio chip to be included in our motherboard. We found that the CM8828 HD-Audio controller and CM9882A Codec family was a good candidate.  After some discussion with them explaining our project, they decided to support us. Furthermore, they have sent the Evaluation Board to Acube.

Maybe more important is the fact that C-Media will provide the needed chips for the production of our notebook. They know that their chips will be in our Open Source Hardware motherboard and will provide us with the needed information to write drivers as may be needed. In addition to this, we have ordered three pci sound cards based on CM8828/CM9882A to test with our T2080 Devkits and for Acube developments.

In the end, all these little steps are very interesting for our project, as this audio chip has high end specs but the most important point is that we have a direct and  good communication with the manufacturer. We want to thank C-Media for supporting our project and believe in Open Source Hardware.
