Ubuntu will not support RISC-V CPUs without RVA23 support going further, so this is stuck on 24.04 forever. There is no official Debian image either, and the Ubuntu version uses fixed kernel 6.6.47 with no further updates (it is not even installed from a repo). I own one since a couple months ago but I already regret the purchase.

This is me with every single SBC

I don't like RISC-V unless it has a good GPU

Theoretically the vector extensions in a RISC-V could be scaled considerably, it seems to me, especially when combined with the extension proposed here: https://github.com/spacemit-com/riscv-ime-extension-spec

That said, the actual processor cores in this SBC seem to max out at 256 bit registers, which does not seem to be a lot.

Building Debian for this board is pretty easy nowadays. You can also find prebuilt images.

Want to share any links, particularly about building one's own Debian image? I'm especially curious about the bootloader.

I owned every generation of Raspberry Pi and I still use the 5, 4, 3, and even a 2 Model B. Their software/ecosystem support is unmatched by any other SBC line.

A good example. There is also a link to builscripts.

Absolutely smoked by rpi5, often by rpi4. To make matters worse, a radically unsupported core with no mainline support. https://www.phoronix.com/review/orange-pi-rv2-benchmarks/2

I can accept the performance issues for now- it's an emerging platform, and hasn't had the huge amounts of resources poured into it like ARM. There's a chicken-and-egg problem here, since those resources will be limited since people aren't buying RISC-V equipment, which limits the incentive to commit resources, etc.

But what I cannot accept is the truly awful documentation and software support from the vendors. This is where Raspberry Pi shines, and is IMO one of the most significant factors in its success. I'm excited that RPi is dipping their toes into the RISC-V pool with the Hazard3 cores in the RP2350- perhaps they will be able to release a Raspberry Pi RISC-V edition board some day.

But I'm hesitant to buy one of the current RV SBCs, so I guess I'm part of the problem.

I'm also surprised that there aren't any startups producing small, simple CPUs and SOCs outside of China (as least, none that I'm aware of). Is there no investment available in India, N. America, Japan, Europe, Israel (* not bringing the current situation into this, just noting they have chip fabs)? Fabricating chips is not cheap, but the first ones don't need to be the top-of-the-line TSMC 3nm process.

Don't buy an Orange Lie.

I used to occasionally buy a single board computer ~10 to ~5 years ago.

Then I waited until SBC's reached the 32GB RAM level. The first such affordable and performant board was an Orange Pi 5+ or 5B (I should double check, may add a comment later).

I believe I wanted the Orange Pi 5+ but it was sold out, so I ordered and paid for the Orange Pi 5B (the 2 ethernet port variant) which was a bit more expensive but was still for sale. Both had 32GB RAM, my main requirement. There were multiple "flavors", with power adapters or with case or with memory card or eMMC etc. I chose the memory/eMMC version.

I sent a message to ask them to give me heads-up when they are about to ship mine, and then I was patient.

Then I waited, and waited, and waited.

Too patient, after a long while I start looking up on forums if other people are also waiting. I discover I am not the only one. So I take up contact again and ask when the board will be shipped.

They inform me the SBC is no longer manufactured, and offer me inflation-devalued currency.

I check which single board computers they still sell, and indeed they no longer sell the 5B variant, but now the 5+ is back in stock.

I ask them if they can just ship me the 5+ instead of the 5B. They refuse.

OK, I ask them how much I can pay extra so they ship me the 5+ instead of their unilaterally discontinued 5B.

They refuse.

A few months pass by. I ask again if they intend to ship the 5B as agreed, or the 5+ as a substitute.

So here comes the orange Lie:

They claim they shipped it, and provide a DHL link.

I first name (same as my father's) is German, even though I live in Belgium.

Their DHL link, is a shipment to somewhere in Germany, with a weight far below the weight of a single board computer, and which was delivered just minutes before their sending this message claiming shipped delivery.

I confront them that the weight of the SBC is advertised on their own site, and their DHL delivery link lists a value far below it, that I live in Belgium and the shipping address was in Belgium (I have 0 links to Germany), and that the timing of the delivery and their response message is so close it suggests people at customer support (presumably without arbitrary access to deliveries outside of the case) asked colleagues to let them know if a case pops up with a German delivery, so they can manually copy and paste bluff delivery of product X to customer Y as if it was my order to me into the message.

I confront them and ask them to answer a numbered list of questions.

They refuse to answer the questions (they can't without incriminating themselves), instead they offer me my money back.

Don't buy into the orange lie.

If you work for Orange Pie, feel free to msg me with a way to contact you, if you positively resolve my case I will remove this message.

Are there any SBC with memory slot so that i can plug in 32GiB or more of RAM?

the only one i've seen in a comparably small form factor is the UDOO Bolt https://www.udoo.org/discover-the-udoo-bolt/

but it's an x86 system and pricey, and borderline not an SBC

memory is soldered in most of these smaller systems including the Orange Pi and it's the main price differentiator

RAM is by far the most expensive thing in those systems past the very lowest specs, this one goes from 2GiB to 8GiB AFAICS (amazon page: https://www.amazon.com/Orange-Pi-RV2-Development-Ubuntu24-04... )

the Orange Pi 5 plus comes with 16GiB but the price jumps to US$160+ or 32GiB for US$ 270+
