The B35APO Computer Architectures course based on #riscv and our #qtrvsim simulator reached new (re)usability level, updated slides in the LaTeX Beamer format for lecture 1 to 10 are translated to English, PDF, CC-BY-SA Slide Sources at #cvut FEE GitLab and on GitHub. The feedback, corrections, suggestion, reuse and cooperation are welcomed. The lectures recording are available on community driven PeerTube server https://vhsky.cz/w/p/8Ejstt3Tfh8mWGcjQcEL2S and CTU FEE B35APO YouTube List. The online site with links to more related courses and on-line QtRvSim https://comparch.edu.cvut.cz/ WASM application allows even online evaluation of simple #riscv assembly and C exercises.
A new RISC-V SBC. 
Here is the desktop set up on the Mango Pi Pro #RISCV #SBC. As mentioned earlier it is running minimal #LXDE on top of a vanilla install of #Ubuntu server 24.10.
I have peeled back a few things, such as audio since the basic Ubuntu install does not have the stuff to run #HDMI #audio (I could do look into this more but eh). I will do some more tinkering with the ISO from the official Mango Pi website. Lets see how that goes

The #EclipseFdn is hiring an HW Verification Engineer for its OpenHW Foundation. Working as a member of the Eclipse Research Team, the candidate will work to verify industrial-grade #opensource IPs based on #RISCV.

Yay, finally all the pieces have come together and I have finally been able to compile Qt 6.9 and @kde Plasma development version (what is to be released as 6.4 in June) for my @bananapi BPI-F3, a RISC-V single-board (mini) computer. Plasma does start and run, but looks like QML/QtQuick applications (which includes the desktop itself) have rendering problems 
Qt Widget apps render/run just fine. Now to figure out where the problem is…
"Kaleidoscopico", a RISC-V demo from #LFT written in assembly, running on a Raspberry Pi Pico 2 microcontroller.
This is the first release where we have our Fedora RISC-V images available at the same time as the general release! Get your Fedora 42 RISC-V images and join the momentum behind this open architecture.

A team of researchers from Fudan University in Shanghai developed a 2D chip with 5,931 molybdenum disulfide transistors, making it the most complex 2D logic circuit to date. The chip is built using #RISCV architecture.
Despite the lab-level fabrication capabilities, they achieved a manufacturing yield of 99.77 percent. RV32-WUJI consumes only 0.43 mw of power and is a significant step towards the development of higher-density chips in the future.

The more I learn about Apple Silicon Macs, the less appealing they are to me.
Let's go #RISCV!
Is #RISCV any fun to write assembly language in? #asm #assemblylanguage #programming

Never underestimate the impact of open source on long-term development in innovation in hardware and software.
I remember discussions claiming that RISC-V would never compete with other processors, and so on. It reminds me of the discussions in the late nineties where people said Linux was nice but would never compete with SunOS, AIX, or HP/UX.
People should focus on RISC-V, not just ARM or other proprietary architecture.
Looking at recent changes and RISC-V evolutions:
A RISC-V 32-bit microprocessor based on two-dimensional semiconductors -https://archive.org/details/s41586-025-08759-9
2D 32-bit RISC-V processor https://www.electronicsweekly.com/news/business/2d-32-bit-risc-v-processor-2025-04/
The original open source design is based on https://github.com/olofk/serv SERV - The SErial RISC-V CPU made by Olof Kindgren
When Prof. Krste Asanović and graduate student Yunsup Lee started the open-source project 10 years ago, I suppose they didn’t expect such an impact today. And it seems to be just the beginning.
Now it is done: At #OpenPrinting we have now full #RISCV support by our 6 Snaps in the Snap Store:
https://snapcraft.io/publisher/openprinting
- CUPS: Full printing stack
- ipp-usb: IPP-over-USB daemon for driverless USB printing
- 4 Printer Applications: All printer drivers which typically come with Linux distros, ~10000 legacy printers supported
These Snaps can be used on the the #DeepComputing Risc-V board for @frameworkcomputer laptops, also with #Ubuntu Core and #UbuntuCoreDesktop.
@frameworkcomputer @zygoon Also the IPP-over-USB daemon ipp-usb is now available for #RISCV in the #Snap Store.
For everyone who wants to build #Snap packages on the #DeepComputing #RISCV board for #Framework laptops:
You need to install DeepComputing's #Ubuntu 24.04 image, but its kernel does not support bridge networking, needed by the LXD which #snapcraft uses, so snapping does not work.
A fixed kernel is already available:
Just install all *.deb files and reboot.
Thanks, Heinrich Schuchardt (xypron), RISC-V expert at #Canonical!
The #OpenPrinting #CUPS #Snap is now available for #RISCV in the Snap Store!
To build it it just needed to add #riscv64 as supported architecture in the snapcraft.yaml file.
I has taken 2:30 hours (!) to build on my #DeepComputing / #Framework RISC-V board, and the build servers of the Snap Store need the same time to build it.
Thanks to Heinrich Schuchardt (xypron), RISC-V expert at #Canonical, for providing me a kernel which does bridge networking.
