CE mark certification financed! New campaign for the software part and heat pipes

Posted on by Communications Team

Once again we want to thank you all for the great support and great enthusiasm you demonstrated during the CE mark donation campaign. We ended the campaign with a total amount of 12500€ (https://en.wikipedia.org/wiki/CE_marking), this is a huge milestone for us all and we are so very grateful.

By financing the CE mark certification you have shown us that you believe in the project and our vision of creating a fully open hardware notebook motherboard based on the alternative PowerPC CPU architecture.

We closed the campaign with around € 4000 more than expected, and this extra money will cover some of the extra and unplanned costs we faced for the increased price of electronic components and the extra costs of the three MXM video cards (360 USD each).

The CE mark certification is a mandatory requirement for selling electronic products in the European Union. It ensures that our notebook motherboard meets the safety, health and environmental standards of the EU. Without it, ACube Systems would not be able to launch and sell our Notebook on the EU market. Getting the CE mark certification is not an easy nor a cheap process as it involves rigorous testing, documentation and quality controls.

Legacy Slimbook Eclipse cooling metal pipes to be redesigned

However, the CE certification process can be performed only when the product can be considered completely finished, and that means once the board works, the cooling metal pipes are in place and all is assembled into the selected slimbook eclipse chassis.

Current activities

The Tyche Motherboard has surpassed all the electrical checks, and now the the key activities being performed concentrate on the hardware initialization procedures.

The start-up ramp was carefully calibrated, programming a complex integrated circuit with some logic (i.e. ramps, voltage thresholds, internal ways of making the PWM regulator work, and so on).

The Complex Programmable Logic Device (CPLD) is a Lattice LCMXO640C-3TN100C FPGA is programmed to manage all external peripherals connected to it (see the block diagram and wiring diagram on page 15), manage the interrupts, data, boot reads, set resources according to the CPU and is able to reset all peripherals.

Working on U-Boot

Currently, a small team of volunteers are working on U-Boot . We are decided to buy a JTAG debugger, a quite useful tool indeed that will make the hardware debugging much easier.

We learnt how to configure and build U-Boot, and we set up a cross-development PowerPC toolchain and the related Device Tree Blob that is used to describe the physical configuration of each hardware component available on the motherboard. You may keep an eye on our attempts by looking at our GitLab pages. We started by re-compiling our old U-Boot binary dating back to 2019, the one that we are currently using on our NXP T2080RDB devkit and also trying to compile a newer U-Boot version from a the DENX mainline vanilla branch without our patches. We are now kindly assisted by Max Tretene, the same guy working at ACube Systems that compiles U-Boot for their motherboards such as the Sam440 or the Sam460ex. Max is currently available to introduce hardware support to AMD/ATI Radeon graphics cards in U-Boot, (ndr.: he recently told us that his spare times is not enough so we are proposing him to work under payment) stay tuned for more in-depth posts about it. In the hope of speeding up the development, we provided Max Tretene with our NXP T2080RDB devkit in early June.

We want to thank the dedicated small group of volunteers and especially Max Tretene for their precious spare time spent in trying to configure and compile U-Boot, we very much appreciate their availability and effort, even if a successful result is yet to comes. In addition, we greatly appreciated the offer made by a professional engineer – not to be disclosed yet- that is ready to work for us on U-Boot for a very reasonable amount of money.

Launch of a new fundraising campaign

After quite some internal discussion, we finally decided to launch a new fundraising campaign aimed at support and speeding up multiple actions:

  1. Buy a JTAG Debugger
  2. Design of the heat pipes for cooling down both the CPU and the video card;
  3. Prototype of a heat pipe fitting our Slimbook chassis, a requirement to proceed to the CE certification process;
  4. Development of an AMD/ATI Radeon driver for U-Boot;
  5. Development of the device thee to fully exploit each hardware component of the board;
  6. Compile a custom  U-Boot binary from up-to-date DENX sources;
  7. Provide the entire toolchain for cross compiling U-Boot and the device tree for PowerPC;
  8. Provide the documentation detailing all the technical aspects of both U-Boot and the device tree so that anybody will be able to understand how to rebuild it from scratch and how to customize it.

In carrying out these actions, we will try our best to optimize both the support of the involved volunteers (any additional help is more than welcome!) and the contracted software engineer(s).

At the moment we only have a rough idea of the amount of required hours of paid work required to complete U-Boot and its closely related device tree. After some internal investigation, a reasonable rough estimate could be at least 100 hours, but it may take more to reach the goal.

We do not have yet a formal quotation of the design of the heat pipes for cooling down both the CPU and the MXM video card. During an informal discussion with electronic engineers that have experience in the design and production of these heat pipes, we estimated approximately 10000 euros.

To sum up, the title of next campaign is “Development of software components and heat pipes for the Powerboard Tyche” and its breakdown costs are the following:

  • Around 100 hours of work of a software engineer(s) for the customized U-Boot, the device tree and the AMD/ATI Radeon video driver: 5000 euros
  • JTAG debugger 1000 euro
  • design of the heat pipes and production of 3 of them for the three prototypes: 10000 euro

The estimated amount to collect with the next campaign is 16000 euros.

We really hope that you will assist us once again during this final journey. We are that close to making it happen: a 64 bit, multi core, PowerPC based notebook fully open hardware with up to today’s standards devices and interfaces!

Prototypes testing results

The laptop prototypes testing is progressing great. We tested the primary power supply stage of the CPU, one the most power hungry components in the board, and it is being fine-tuned thanks to a programming apparatus. The chip in charge to power up the CPU NXP T2080 is the Texas Instruments TPS544B20RVFT (Switching Voltage Regulators 4.5-18V 20A SWIFT) as explained at page 37 in our electrical schematics.

The start-up ramp needs to be carefully calibrated, a complex integrated circuit with a some logic that needs to be programmed to make it work properly (i.e. ramps, voltage thresholds, internal ways of making the PWM regulator work, and so on).

The other power supplies are a half a dozen voltage regulators and are meant to power elements such as the PCIe, the RAM, the internal peripheral buses, the connected devices, the Non-Volatile Memory Express (NVMe) and the clock generators the are essential to make the board work properly. The Eclipse Legacy Battery was tested and is recharging properly.

The Complex Programmable Logic Device (CPLD) is a Lattice LCMXO640C-3TN100C FPGA and has to be programmed to manage all those external peripherals connected to it (see the block diagram and wiring diagram on page 15 ), manage interrupts, data, boot reads, set resources according to the CPU and reset all peripherals.

So far so good, the electronic design seems to work correctly, at the moment we are only fine-tuning each electronic component. If all checks continues like this, we might end all electronic debugging in the next few weeks and we can consider this very delicate phase successfully completed. After that, we plan to place the first code in the CPLD, and right after that we should be ready to load U-Boot, the first-stage and second-stage bootloader. We are trying to re-patch a recent version of U-Boot, quite some time has passed since we patched it to make it recognizing the graphic board we mounted on the PCIe port on the NXP T2080RDB board. Not just that, we must carefully customize the device tree to correctly map all peripherals available on the motherboard.

If for it concern the electronical components we can safely rely on the (paid) support of an expert engineer, for setting up U-Boot it’s up to us to make it work properly, and more importantly, to make it correctly recognize all peripherals, especially the SD card, the FLASH and, even more importantly, the two DDR3L RAM slots.

We would like to thank everyone for the continuous flow of donations, and please, continue to do so.

At the moment we still need funding to cover the extra costs we faced for the simply crazy prices we paid for the electronical components mounted on the prototypes motherboards and especially for getting our hands on two MXM graphic boards based on AMD chips.

For two MXM AMD E9174 video cards with 4GB RAM we have spent 780 dollars ( 360 each) and 185 euro of import Tax around 965 euro .Considering all chips, the cost of each prototype resulted 1200 euros higher than what was initially planned 4392 euros more (1200 x 3 + 22% VAT). So we need to collect around 5357 euro more than the goal of the last donation campaign.

Donations and professional for u-boot

In addition, after an initial round of experiments, we are still struggling to successfully customize U-Boot and to properly setup the device tree. Most of us already spent quite some time on the task during our spare time (remember, we are all volunteers with a proper day job and a personal life ;), so we are seriously evaluating to assign the job to a professional to get the job done in a reasonable amount of time, and to do that we need your financial support!

Prototypes ready, let’s proceed to test them.

Finally, the three prototypes are ready as you can clearly see from the pictures below.

The resulting cost of each prototype resulted in 1200 euros (without VAT) higher than what was initially planned due to the global shortages of electronic components that have skyrocketed prices of some important chips. So, more donations are needed to fund these 4392 euros more (1200 x 3 + 22% VAT).

Now the Hardware Tests stage has started, but prior to that we still need to solder the HDMI connector that has arrived too late to be included during the production phase.

Soon, our Open Hardware motherboard called “Powerboard Tyche” will be inserted in its notebook body chassis for starting the multiple hardware tests.
Below, you can see a picture of the old dummy PCB used for testing how to fit in the notebook.

Powerboard Tyche PCB source

This work was made using Mentor Expedition and it is ready and uploaded into our repository with all reported issues fixed, including issue number 5, the last one corrected . Thanks to our collaborators we are able to export this work using Altium form so the next days we will publish it and we will try to convert it to Open Source Kicad format ( and probably loosing something in the conversion process) . In our older post we have give more details regarding the PCB sources.

Prototypes in production despite heavy chip shortages

Posted on by Communications Team

We were supposed to start the production of the laptop prototypes at the end of last September but we stumble upon skyrocketing prices, especially regarding four fundamental chips. We had no other choice but to pay those incredible much higher prices, the only alternative would have been to stop all our activities.

We are glad to inform you that this week the prototypes production has started and – finger crossed – we are expecting them to be ready in the beginning of November. The following are the four fundamental chips and their actual cost:

  • Marvell Sata 3 controller 88SE9235A1-NAA2C000, around 130 euro per piece + VAT, 1 per PCB, total 3 pieces
  • TPS544B20RVFT 4.5-V to 18-V, 20-A synchronous SWIFT™ buck converter with PMBus programmability and monitoring around 550 euro per piece + VAT, 1 per PCB, total 3 pieces
  • 6-port, 12-lane, PCIe 2.0 Packet Switch PI7C9X2G612GP – Diodes around 250 euro per piece + VAT, 1 per PCB, total 3 pieces
  • Surge Suppressors 100V OV, UV, OC and Reverse Supply Protection Controller with -50mV Reverse Threshold LTC4368IDD-1#PBF around 100 euro per piece + VAT, 1 per PCB, total 3 pieces

The HDMI connectors (2041481-1) were completely impossible to find on the market in a reasonable amount of time. After long research, we could finally solve the problem thanks once again to the kind support of Slimbook, they will soon send us three connectors, one for each prototype.

Considering all chips, the cost of each prototype resulted 1200 euros higher than what was initially planned, 3600 euros more ( + 22% VAT) considering all three prototypes currently in production. You may find more information about these three prototypes in the post of July 2022 and May 2022.

As already stated in our post back in July, we are still asking you to continue donating as to help us supporting the dramatic increase in the actual costs we personally anticipated to proceed with the production. You may continue use the current campaign to donate.

Our presence for October-November in Free Software and IT events

We have planned our next speech at the LinuxDay in Milan (Italy) on the 22nd of October.

We are at NXP Technology Days in Milano on 27th October with our exposition, we are very glad for this opportunity that NXP has given us.

We hope to first show at least one prototype at the SFScon – Free Software Conference – on the 11th of November in Bolzano (Italy) in the occasion of our next speech.

Ready for Prototypes production with reworked PCB design with all available components

AMD MXM video cards in our hands!

As we have already published in July’s post, our AMD retailer informed us that the new MXM video cards will not be available. We have selected a manufacturer that still produce and sell affordable MXM AMD based video cards (Type A – size 82mm x 70mm) .

At the moment, AMD open source drivers are better than NVIDIA ones, so in our opinion it is the best option for GNU/Linux and the unique solution to support Amiga OS derivates. Then, even if it is easier to find NVIDIA MXM Video Cards ( Type A) we are still preferring to use AMD MXM video cards.

As a consequence, we have ordered and received two MXM AMD E9174 video cards with 4GB RAM, actually is the only option available as the 2GB version is not available anymore.

Main Features
AMD Embedded Radeon E9174
Supports DirectX 12, Vulkan, OpenGL 4.5, Open CL 2.0
MXM 3.0 Type A
Support for 5 outputs
128-bit width, 4GB, GDDR5 Memory

They are ready to be tested with our prototypes. We have spent 780 dollars ( 360 each) and 185 euro of import Tax. It was possible to buy them thanks to the last donations that surpassed the goal of the dedicated CE Certification donation campaign so, thanks again to all donors

Published Powerboard Tyche PCB reworked source

Finally, the reworked PCB design source of Powerboard Tyche with the updated available components is ready ( in older posts you can go more deep about “our” electronic components shortage issues). This work was made using Mentor Expedition and it is ready and uploaded into our repository with all reported issues fixed, including issue number 5, the last one corrected . Thanks to our collaborators we are able to export this work using Altium form so the next days we will publish it and we will try to convert it to Open Source Kicad format ( and probably loosing something in the conversion process) . In our older post we have give more details regarding the PCB sources.

Inside Output folder you can find many interesting files easy simple viewable like the “the plot separate sheet” CAM350/DFMSTREAM and the Motherboard Assembly TOP and BUTTOM.

As a conclusion now we have everything to produce and make the hardware tests in September.
