Hmm. As a fairly non-experienced person with a strong interest in experimenting with RISC-V, I read the comments here, and the article, and still feel, maybe this isn't the thing to get me started. Maybe the ecosystem still isn't there for a beginner to jump in. Is there such a thing as a (cheap) SBC that runs RISC-V, which has good documentation (books, forums, whatever) on getting started programming on it? I'd lik…

You don't need new hardware for that, you can just use qemu.

And what will Qemu emulate ? A nonexisting processor ? /s

Yes? How is that a problem? If you're interested in learning the RISC-V ISA, which is what I gathered from OP's post, the specific CPU doesn't matter much.

I am moreso looking for an actual board, maybe a few flashy lights, ya know, all that. I've played with QEMU a bit for a few little things, it's fun enough, but I'd like to play with some RISC-V hardware - again, if possible, if there were something appropriate for a relative beginner to get going.

As per the article: "The biggest difference between the two boars is that the Orange Pi RV has a 1.5 GHz StarFive JH7110 quad-core processor, while the new Orange Pi RV2 has a an octa-core Ky X1 chip with a 2 TOPS AI accelerator." The link you posted goes to the exact same board as in the article.

It's not about the article, but the comment from u/12101111: > It's a cheaper Spacemit K1. > The CPU spec from dtb: > compatible = "ky,x60", "riscv"; model = "Ky(R) X60"; riscv,isa = "rv64imafdcv"; riscv,isa-extensions = "i", "m", "a", "f", "d", "c", "v", "zicbom", "zicboz", "zicntr", "zicond", "zicsr", "zifencei", "zihintpause", "zihpm", "zfh", "zfhmin", "zba", "zbb", "zbc", "zbs", "zkt", "zvfh", "zvfhmin", "zvkt",…

From memory, the SpacemiT K1 doesn't support extensions like Zvkt?

EDIT: okay, looks like the official documentation lists it, but many places I looked didn't. Maybe it wasn't being detected in cpuinfo?

Why is that unacceptable?

If I have an SD card for extra storage and tuck it away somewhere, any interruption in power would mean it needs to be manually reset. I actually wanted something with SD storage that I could turn on and off remotely.

I think the SD card is thought of as the worst tier of storage, so if you're not wanting to boot from the SD card, then the idea is to use something like a USB disk etc. Presumably, it causes more problems (bricked devices) if they don't always boot from the SD card preferentially.

One solution would be to always boot from the SD card and either have it partitioned to provide the SD storage that you want, or use the eMMC etc to provide the storage.

I can not find infos about the Vector-extensions ? Is this cpu/board suitable to test the RISC-V Vector extensions ? thx for any insights..

I have one.

Yes, I'm currently using it to successfully test vector instructions. A blog post is being written, but may take a week or so.

Keep an eye on blog.habets.se, or ping me here on HN in about a week.

Seems I can't add another reply, nor edit the one I created. But [here's more info about the Orange Pi RV2 and RVV](https://blog.habets.se/2025/03/Exploring-RISC-V-vector-instr...).
