Lately I’ve been really liking the idea of having something hosted on a RISC-V
machine. RISC-V is a non-proprietary instruction set that is a competitor to
ARM. The idea of having a something running on an open source operating system,
running on an open standard CPU, served from my house, gives me a warm fuzzy
feeling. I was under the impression that most Linux distributions were unstable
on RISC-V. Turns out, I’m wrong about that. From a quick search, the following
have official Debian images: * Beagleboard Beagle-V Ahead
[https://www.beagleboard.org/boards/beaglev-ahead] * Starfive Visionfive 2
[https://ameridroid.com/products/visionfive-2] * Milk-V Mars
[https://milkv.io/mars] and the Pine64 Star64
[https://pine64.com/product-category/star64/] has a community-maintained Armbian
image. Does anyone here have a RISC-V single-board computer doing anything
practical for you?
RISC-V is a non-proprietary instruction set that is an alternative to ARM. I had thought that we were still waiting for a stable Linux distribution on RISC-V devices, but it turns out many RISC-V machines can run Debian already.
Does anyone have a RISC-V device that they use regularly? How has it been working?
Definitely interested - is the mainline situation any better than with ARM?
I’ve been bitten before with a device that “supports” a major distribution, but only if you install our custom pre-built image (good luck auditing what we’ve tweaked) and only with our special pre-built kernel that isn’t even an LTS version, and has a bunch of patches applied to support whatever weird peripherals we decided to throw on the board, and will get exactly 0 updates after the initial release.
Raspberry Pi gets around this by being big enough to get buy in from vendors (Ubuntu distributes a special kernel + firmware bundle), but support for all the other smaller knock offs seem shaky at best

Unfortunately, sounds like “no” currently. The ones that let you install Debian usually provide some kind of custom Debian image for that specific SBC. Like you, I’m not really a fan of that. But apparently there are some desktop motherboards with RISC-V CPUs coming out. Hopefully that will increase the chance of things getting supported in mainline distros.
