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.
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 .
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 .
