Ищу информацию про Risc-V(чисто для саморазвития).
Нашёл вот такой репозиторий на Github. Может кому-то будет полезно :blobfoxnerd:

Okay, I know... I am way too late to the party... But recent #ESP32 cores are #RISC_V? That's pretty fascinating!

Wow, this is actually insanely cool :ablobfoxbongohyper: I've loved the prospect of a totally open, patent unencumbered chipset that Intel or ARM don't have dictatorial powers over. RISC-V seems like it's early days in the consumer sphere, but it's awesome to see it coming to laptops from more established brands.

The Verge: The Framework Laptop 13 is about to become one of the world’s first RISC-V laptops

I'm a bit surprised that Niklaus Wirth et al would use Verillog instead of VHDL to implement Oberon RISC5.

Is anyone well-versed enough to try to bring some light on this topic?

I don't have a preference, but with VHDL being so closely related, at least in style, to the Wirth family of languages, it seems at least somewhat interesting that he would choose the language that is less similar to his own.

Braucht jemand eine #risc5 Spielekonsole mit #debian?

Ja, ich habe auch gelacht… und dabei bin ich schon ein Spinner dessen einziger "Spielerechner" ein altes NUC mit Randgruppen-Linux (Debian Sid) ist.

Some further hardware notes on the VisionFive 2:

First, there are DIP switches to select the boot device—microSD, m.2, or eMMC. But if a bootable microSD is present, it will boot off of that even if the switches are set for the SSD.

Second, I tried watching a YouTube video, and the 3.5 mm audio jack's output was terrible. I don't know if it's a missing codec, cheap part, or just a defect on my board, but my perennial Linux joke still applies:

#RISC5 #Starfive

So; what we have here is a StarFive VisionFive 2 Risc-5 SBC and running #OctoPrint

It's running the `debian69` build from December, latest firmware and Uboot, And.. a custom kernel that I compiled myself with CONFIG_USB_SERIAL* enabled. I compiled this on the VF2 itself; An hour or so with -j4 and the root disk on an NVMe.

It's connected via USB to my Duet3D powered 3D delta printer, and to an elderly Logitech USB webcam.

I'm running OctoPrint and MJPEG-streamer-experimental on it, both are working (and working well).

Installation of both OctoPrint and MJ-streamer was flawless, exactly the same steps that I'd do on a Pi, both worked first time. I imported a backup from the Pi that normally controls this machine into Octoprint, disabled the PSU control plugin since that is Pi-GPIO specific, and was printing this 10 mins later....

I am rather impressed at how far along Linux/Risc-V is getting.

Thinking about poking a bit at some bare-metal RISC-V and wondering how hard it will actually be. The bootstrapping I've done at all has been ATMega and friends and it'd be interesting to poke around a bit I guess.

There are definitely boards aimed at the kind of RasPi or Arduino crowd but is it really just the same in the end?

Book for the ISA is on the way, anyone have links for the kind of stuff I'm trying to poke at?

#rustlang resources is a major plus, even if it's more complicated.
