It's gotten a little quiet around SBCs for hobbyists like myself and since the unfortunate death of my VF2 I haven't had any new board in mind to buy to go back to tinkering with RISC-V. But I regularily check in to this sub to see if there are new chips or boards being released - which doesn't seem to be the case.
My main usecase is a homelab; little server things and just trying to see how much I can run on them compared to my arm64 fleet. :) The VF2 was super close actually; aside from k3s' build being a little wonky and some containers missing back then, it actually compiled and ran...somewhat. Recent new releases also introduced RISC-V images, so I would love to use a few of them.
So what are some boards for this use? I have a plain rack shelf where some SBCs just live, cluttered in a 2U space. There's still room.
Any places aside from here where I could look out for RISC-V news perhaps?
Thanks!

Recommendations for M.2 to PCIE X16 adapters?
I'd like to add a Radeon 7350 to my OrangePi RV2 so I can see if the driver package others are using on the BananaPi BPI-F3 will work. I'm using the 2280 on the bottom for my hard drive, so I'll be plugging it in to the 2230 M.2 socket on top. What are you using for your adapter if you're running external video?
An Amazon link would be great (I would do Aliexpress but... yeah).

Benchmark with vulkan
Hi, I’m trying to run some Vulkan-based GPU benchmarks — specifically vkmark and vkpeak — on my Orange Pi RISC-V board.
• vkmark doesn’t run because it “failed to find a connected DRM connector.” I assume that’s because the board doesn’t have a proper user-space graphics setup.
• vkpeak runs, but some tests return a score of 0. I discovered that’s likely because vkpeak doesn’t recognize the GPU, so it ends up running on the CPU via software rendering.

Basic dual-NIC board
Hello all! I'm hoping to set up a router using RISC-V hardware. This means I don't need the 4 or 8gb a lot of boards offer. All I do need is more than 1 rj45 port. The compute power only needs to pass packets and do other routerly things. No switching, no WiFi, that'll all be handled by other devices. Just internet in one hole, internet out the other. Can the brain trust assist me in finding affordable hardware?
PS we can skip the 2.5gb conversation as I'm Australian, and our download speeds won't surpass gigabit in my lifetime lol

Would you say RISC-V has been successful in killing some of the other lesser known chip ISAs?
Of course it's nowhere near how x64 and ARM displaced everyone, but a lot of companies like Andes Technology, Espressif, and even NVIDIA are beginning to phase out proprietary licensed ISAs in small microcontroller units in favour of RISC-V, obviously because it eases expenses.

Hardware most similar to QEMU's virt machine.
What's the closest real thing similar to QEMU's virt rv32i, 1 hart machine?
Would love to see my OS running on real hardware, not just qemu, but what should I purchase that would need least amount of rewriting?

Milk-V Jupiter GPU support, any current updates/documentation?
Hi, a while back I purchased a Milk-V Jupiter, and I'm curious about getting a GPU running on it. I've seen previous work on getting GPUs working including some of Opvolger's work on getting cards like the R9 290 working. However, I unfortunately didn't have a compatible GPU on hand to test with. What sparked my curiosity in GPU support again was that in a more recent video from Jeff Geerling (Here around the 7:48 mark) he mentioned having an R5 230 sent to him for testing on the Jupiter, despite this I can't find any further mention on Milk-V working on GPU support for the Jupiter with the R5 230. Is there any available documentation on how to replicate this?

My 1602 LCD is only showing white boxes in the upper row.
Hi, I am a beginner in embedded programming and I'm trying to code in C a program that will display a 'hello world' message on the lcd display. But the lcd display is only showing white boxes even without downloading any code onto the mcu. I am using the GD32VF103 mcu. Does anyone know what is wrong with it?
This is how I have connected the wires
