Schematics reviewed and published!

We have known each other for several years now, working together with supporters who have backed us through the long process of creating notebook prototypes. Over the last eight months, we have focused on developing a desktop version largely redesigned to be immediately functional.

As promised, the sources for our desktop board have been reviewed by NXP. They suggested a few changes, which we have implemented. The review process cost us an additional โ‚ฌ850, but it was worth it: we have improved our schematics and PCB design just in time for the prototypes.

Great news: NXP confirmed we can publish the schematics with an Open Hardware License! We have already uploaded the PDF version to GitLab.

GitLab Repository Powerboard Tyche Desktop Schematics

However, before publishing the raw source files, we need to convert them from the proprietary OrCAD format to KiCad to ensure everyone can use them. We need collaborators to help us bridge this gap.

If you would like to reserve a production desktop board this summer, we need donations to cover โ‚ฌ6,100 for the remaining costs of the PCB design, as well as the expenses associated with prototypes and testing in the coming months. ACube Systems will handle the production because we are a nonprofit organization not allowed to sell physical products.

We are doing what is needed to reach production, despite the obstacles. The difficult part, the uncertainty, is behind us. Now we are missing a very simple ingredient: funds. We need to raise a few thousand euros in a window of 2-3 months. Simple, but not easy.

Join us on this journey!

Donate, tell your friends, and share our project. In order to enjoy the PowerPC motherboard later, we must all work together now by joining the donation campaign in large numbers.

Troubleshooting the T2080RDB DevKit: stuck in sleep

As many of you recall from our post on December 24th, 2025, we hit a significant roadblock with our hardware testing. During the last shipment of one of the DevKits at our disposal, the power supply (which we had already replaced) and the T2080 motherboard sustained damage.

Since then, we have spent quite a few hours on the workbench trying to revive the NXP T2080RDB DevKit, but the situation remains critical.

A photo of the NXP T2080RDB reference DevKit board.

The symptoms

The behavior is consistent but frustrating. We hooked up the serial console, hoping for some life, but unfortunately, no information came out of the serial port. It is complete silence.

As soon as we power up the board, a specific LED close to the CPU turns on. After checking the technical documentation, this indicator seems to signal that the CPU is being kept in a sleep state.

The investigation

So far, none of our attempts have led to a breakthrough or even a solid theory, so we are currently clueless.

To dig deeper, we had to get creative with our quite limited diagnostic tools. We decided to investigate the electronic components and connections on the DevKit board using a piece of classic equipment we had on hand: a very old Tektronix T935A oscilloscope.

Photograph showing a flat signal in the oscilloscope connected to components of the T2080RDB devkit.

For those interested in vintage test gear, the Tektronix T935 is a 35 MHz dual-channel analog scope with a delayed timebase from the T900 series. The specific model we are using, the T935A, is an upgraded version of the standard T935 (and the single-timebase T932).

The “A-series” adds some very useful features that came in handy during our probing:

  • Differential input (A-B)
  • X/Y mode in full sensitivity for both channels
  • DC trigger coupling and composite trigger
  • User-selectable CHOP/ALT mode (Non-A series select this automatically based on sweep rate)

You can read more about this workhorse on the Tektronix Wiki.

What We Tested

We painstakingly probed the board using the T935A. Although it cannot detect the high-frequency bus operation of the CPU or DDR lines, many components can be seen. High-impedance readings allow us to check the pins, and we can verify the power lines.

Beyond signal probing, we also attempted to force the board to boot from different media. We altered the DIP switches to try booting from the SD card, the NAND flash, and the SPI flash. The oscilloscope should show us chip selects of them to show read activity.

We tested the electric signals associated with:

  • The main power lines (fine)
  • The SD card interface (no activity)
  • The NOR and NAND flash interfaces (no activity)
  • The oscillators that provide clock sources for CPU and RAM (fine: 66 MHz and 133 MHz)
  • The reset lines of the T2080 CPU (one good, one shows no activity)
  • The CPU clock input line (dead?)

Photograph taken during the electrical track testing session of some components of the T2080RDB devkit.

Current status and next steps

Unfortunately, even with a detailed signal analysis and configuration changes, the CPU remains stuck in reset. The CPLD attempts to pull the CPU out of reset; however, the clock input is dead, and the HRESET line stays low.

The boot phase fails very early. Perhaps the CPLD did not complete the sequence, or maybe it is corrupted. There may also be a hardware issue. A visual inspection shows nothing apparent; we removed the CPU heatsink. The CPU remains cool, which proves that it is not running.

If anyone has experience with T2080RDB boards getting stuck in a reset state or has suggestions on what to probe next, please reach out!

First PCB Desktop Layout!

Today we publish here ( above) an export from PCB design of our PowerPC Desktop motherboard (based on processor NXP T2080) , you can see the motherboard top view with components and connectors, it reflect the progress on pcb design, that is going fast. Before the end of January will be completed !! In January should be defined the costs and timing for the production of the prototypes.

  • The dispositions of components on the board are not final.
  • As requested by our association members there are 4 holes 30-42-60-80 for the left M.2 connector.
  • The two Ethernet are one on top of the other.
  • There is even a digital audio output.
  • There are 3 PCIE connectors: 16x, 4x Open ( with space for 8x and 16x), 1x

In the mean time that is in progress the donation campaign for the schematics design we open now the donation campaign for the PCB design.

    Headline

    Donations are liberal and not refundable

    The Power Progress Community is a nonprofit organization established in Italy. The Italian law allow to collect liberal and not refundable donations meant to pursue the missions and projects of the association and not give back products.

    Restrictions for a nonprofit associations in Italy

    An organization like ours has to take into account the following constraints:

    A nonprofit association cannot make commercial products;The association can receive donations, but cannot refund them;The association must be coherent with its mission, and is allowed to ask for donations for their achieving the goals.

    So, what we can do to start our project is based on the points below:

    The association can have a particular goal to reach and ask donation to achieve it, but it cannot give back the money (no refunds).Donation must be altruist so, no one will receive something back for their donation.Italian law allows an association to finance an R&D for a project or activity.

    What happens if the campaign fails?

    As stated above, we will not be able to refund the donors in any case. Because of that, if the money collected is not enough to fund this research we will use it for another goal within the mission of the organization.

    Headline

    Will all the received money be used for the research?

    Almost, as any payment platform available, either PayPal, Stripe or the Bank account transfers, have a fee applied to each donation. As non-profit organization we have inside EU 1,8%+0,35euro of commission, outside EU 2,8%+0,35 euro ( from some country we see that could arrive to 4% of commission) for paypal. In case your bank transfer is from outside EU, for us bank commission cost is high: 6 euro, so we strongly suggest to use service like Transferwise to decrease the commission cost for both.

    Open Hardware Certificaion

    As a final remark, we will try to adhere to the Open Source Hardware requirements in the design of this laptop motherboard, therefore we are strongly committed in avoiding any hardware component requiring an NDA (Not Disclosure Agreement).

    For this purpose, we have contacted many chips vendors in order to verify their agreement to distribute as Open Source Hardware our electrical schematics and PCB design obtained in this second campaign.

    Among others, NXP which is the company producing the selected CPU, has answered positively for the Powerboard Tyche Notebook that had taken from T2080RDB Revision C design, now we are waiting the level and parts that they agreed for T2080RDB Revision F, that’s the new version that we have use for the new design of Powerboard Tyche Desktop,

    The process required to achieve a fully compliant Open Hardware motherboard, was carefully analyzed by students of the Law and Policy Clinic of New York University School of Law. Thanks to their work, are clear the practical implications of the requirements for the OSWHA Open Hardware certification, and cross-checked our approach and adopted solutions with OSWHA personnel.

    An important part of being considered Open Hardware compliant (OSHWA Open Hardware certification), require that everything that is under our control and that is used to produce our motherboard, should be publicly disclosed, such as schematics, PCB, Gerber-files and all their accompanying information.

    As a consequence, most of the datasheets of the chips used in our schematics are freely downloadable, as well as the schematics and the PCB design.

    In case some of the chip vendors will ask us to remove technical details that we were not supposed to disclose, we will comply to their requests by removing the published material, but that will do not impact on our compliance to OSHWA Open Hardware certification because we could demonstrate that we strived to be as open as we could.

    We are sure that you will be satisfied by the final PCB design, and you will be proud of being one of the contributors that could make materialize the first and only Open Hardware complaint PowerPC desktop motherboard designed around GNU/Linux!!โ€‹


Schematics Design

Before 31 December we should balance the payment for the schematics design plus 850 euro needed to fill the review questionnaire asked by NXP, So we have summed the 850 euro to the running campaign for the Schematics.

PCB Design

We need to pay at beginning of January the 50% of the cost for PCB design that is around 6100 euro, so we have created the PCB design campaign that is 12500 euro ( 10000+VAT+paypal/stripe fees) .


We are going faster as promised, to realize a working Open Hardware PowerPC motherboard in few months , that increase rhythms of design and production, costs and ask us to increase even the rhythm of donations…

Donation is a form of collaboration so apart your one shot or recurrent donation that are welcome, we even ask you to spread all over you can our project so more potential collaborators could join our project.

On 12th December NXP confirm us that the review of our source schematics was submitted, they don’t give us any estimation on how much time they take to do the revision and to give us the permission to publish as Open Hardware the schematics source. After we will have the agreement from NXP we will publish the sources as we do usually, as we have done for our Powerboard Tyche Notebook motherboard sources.

PCB Design Costs and Timing

PCB Design Costs and Timing

In our last post we have announced that we were reviewing the schematics of our Powerboard Tyche Desktop; this careful process involved ACube Systems and one hardware engineer from our team from mid-October to mid-November. So on 10th November we sent our schematics to the PCB design company for quote, that resulted to be around 12500 euros (VAT included). In the next ten days ACube Systems, our actual designer and the PCB design Company will meet to refine every detail like the ATX board dimensions, PCB layers, that should be ten layers.

Schematics Sources Publication

Our hardware designer completed to fill the NXP questionnaire to ease NXP review of Powerboard Tyche Desktop source, so we have forwarded to NXP everything they requested us to allow publishing the parts of our board derived from NXP T2080 RDB Revision F. We asked NXP how much time the review will take, but we don’t have an answer so far. Stay tuned!

After NXP green light we will publish the Powerboard Tyche Desktop schematics on GitLab as usual. Since designer and NXP use Cadence ORCAD, we will convert our motherboard sources to Altium and then KiCad.

Steps before Production

We expect that the PCB design will be completed beginning of February 2026, thus we strongly need donations to pay for the PCB design.

After that, prototypes production could be set up, so signing the manufacturing agreement depends on your donations and on your activity to spread the word about our project and donation campaigns to the world.

If donations keep steady, we then expect to have prototypes in a couple of months (April 2026) so that we can afterward perform hardware tests. If everything goes according to the plan, in June 2026 the hardware test will be successfully completed and we will see booting with Debian PowerPC64 and other GNU/Linux distribution as we are doing with our T2080RDB devkit converted in Desktop from 2016.

Linux Day Milano and SFSCON

As usual our volunteers were ambassadors at Free Software events as we have done in the past on Freeplanet event, FOSDEM 2020, Open Power Summit Open Source Summit, etc…. : this fall we participated at Linux Day Milano on October 25th and SFSCON on 6th-7th November, and as usual we got to involve some more people in our activities!

Sfscon – Bolzano – 7th November 2025 – speech Open Hardware PowerPC Powerboard Tyche Desktop

We want to underline the meaning of our open hardware projects

We have vehicles, appliances, phones that cannot be fixed, because their manuals are not available, they are locked behind DRM, or spare parts are either unavailable or prohibitively expensive. Even more worrisomely, perfectly fine connected devices become useless bricks just because the original manufacturer do not find them profitable anymore. This creates unbelievable amounts of unnecessary waste.

Nowadays, we see laptops with soldered RAM and GPU, absolutely closed design and mostly running closed OSs. Our design that started in 2017 has 2 RAM slots and a separated MXM video card.

Powerboard Tyche Notebook – MXM video card slot and 2 RAM slot

Our notebook motherboard design fits in an already produced notebook shell and uses a PowerPC processor that can keep up with modern mid-end boards, even though its production started in 2012: a true testament of a good design.

In 2006 we have seen that market of notebook and desktop switched completely to x86 (Apple had used PowerPC CPUs until then), but not because of a technical reason. Some of us were looking to a new PowerPC CPU, and since 2012 Freescale (now NXP) produced the second, more power efficient generation of their PowerPC processors, the QoriQ T-Series, we thought that the T2080 could be used in a notebook, being a good tradeoff between the T10xx lower power line and the T4xxx higher performance line. We then started this project website. It was only a faint idea inside someoneโ€™s head, then it was shared with some others on this website and then became something concrete, with hundreds of donors, a design made, prototypes produced and testedโ€ฆ In 2025 we havenโ€™t got yet a production-ready Open Hardware PowerPC notebook, but we have completed the second schematics design and thanks to YOU TRULY we will make production-ready prototypes real.

Our modern societies need to control and manage the technicalities in order to run: electronics and software is nowadays pervasive to every bit of our life, in our homes, in our workplaces, in our vehicles, in critical infrastructures like roads, bridges (yes!), railways, ports, utilities, healthcare…

Image by Tomasz Mikoล‚ajczyk from Pixabay

That’s why it is so important that every country, every community needs to have people capable of designing, producing and validating electronics and software powering every building, vehicle, hospital, medical devices, school, university, aqueduct, sewage treatment, power plant, every piece of the infrastructure we depend on for our lives.

And that’s why is so important that we complete an Open Hardware Desktop designed around free software, involving students, and young, and previously young people, to be able to build the bricks of our society.

Thanks to your support, this Open Hardware Desktop first, and then the Notebook, will demonstrate in practice that a group of common people could create computers that respect our freedom.

Schematics of the Powerboard Tyche Desktop version Completed! Soon starting the PCB design

We now have the complete electronic source design for our new desktop design in our hands!

This week, ACube Systems and some volunteers from our association will review the design. We expect the manufacturer to start setting up the PCB layout for the new Powerboard Tyche Desktop on October 20th. This is part of our strategy to focus on creating a stable, functional desktop version of the core computing platform by the end of 2025.

The PCB design phase (Phase 2) will begin shortly after the schematics and Bill of Materials (BOM) are sent to the manufacturer. We anticipate that this step will allow the manufacturer to provide us with an estimate of the cost and timeline for the PCB layout design. This cost and timing estimate will then be shared with the community “just in time.”

Technical Components and NXP Review

We have verified that the availability of SATA2/3 controllers is poor, and the chip Lattice Silicon Image SiI3132 chip that we selected is no exception. We decided to include it in our desktop board to ensure backward compatibility with SATA devices, such as DVD and HDD.

We do not use the on-chip T2080 SATA2 controller because we prefer to use the T2080’s three x4 PCIe Gen3 configuration to optimize the speed of video cards and storage controllers. This configuration cannot coexist with the on-chip SATA2. In any case, the best performance is possible thanks to our M2 motherboard interfaces.

In our board design, we have an SPI connection for an external LCD, which can be used as a secondary screen or for debugging and diagnostics. It is also useful when setting up u-boot and when no video card is connected to the board.

Our board design includes GPIO connectors that can be used to connect other devices that don’t use USB, SPI, or PCIe buses.

Our desktop design is derived from our old notebook design and the original NXP T2080 RDB (Release F) design. We are integrating many components specified in the reference board, including critical monitoring hardware.

This includes the OnSemi ADT7481ARMZ thermal monitor, which has been upgraded to the OnSemi NCT72. The ADT7481 is used as the thermal monitor or temperature sensor on the original NXP T2080 reference design board. On that board, the ADT7481 (designated U34) is usually connected via the I2C_1 bus with the address 0x40. The T2080 processor itself contains a temperature diode designed to be used with system temperature monitoring devices, such as the Analog Devices ADT7461A. This similar part is mentioned in the documentation for the T1042 chip, which highlights the standard use of such monitoring.

Designers have changed other components from the original T2080 RDB design and our notebook design due to the availability of new compatible models, such as the N25Q512A13 FLASH SPI, which is substituted for the EvKit Micron MT25QL512A due to its limited availability.

Due to the changes in components, we will need to modify the VHDL code of the CPLD chip when we have the prototypes in our hands. Therefore, we must take into account the additional cost of this task.

To ensure full compliance and open-source publication readiness,

  1. The designer will fill out the NXP review questionnaire [draft post 2025-10-12] simultaneously.
  2. The questionnaire and the Cadence schematic source will then be sent to NXP.
  3. The main goal is to receive a full or partial agreement to publish the parts of our design derived from the original NXP T2080 RDB (Release F) as open hardware.

We anticipate a robust boot-up because the components and firmware are similar to those of the stable T2080 RDB. The specific CPLD is programmed using the original CPLD source code of the T2080 RDB. Once NXP grants the necessary agreement, we plan to publish the source schematics and evaluate the use of a recent CERN Open Hardware License version.

Upcoming Project Phases

The next anticipated milestones, pending finalization of cost estimation:

  • Phase 2: PCB design. (tentatively scheduled two months after the completion of the schematics).
  • Phase 3: Prototype production (tentatively scheduled one month after PCB design).
  • Phase 4: Prototype testing (tentatively scheduled one month after prototype production).

We continue to rely on the community’s support. Recurring donations are dedicated to the campaign aimed at recovering costs already incurred for notebook testing and CPLD firmware fixing.

We are searching volunteers to test Debian PPC64 and fix packages

Finally, we need more volunteers to support the necessary software efforts, including Debian PPC64 testing, as we cannot ask for additional donations for this purpose.

Below is an updated list of specs for the desktop board being designed.
