Milk-V Jupiter2 is mini PC with a SpacemiT K3 RISC-V processor

The Milk-V Jupiter2 is a compact computer powered by a SpacemiT K3 processor with an eight-core RVA23 compliant RISC-V processor, Imagination BXM-4-64-MC1 graphics, and support for up to 60 TOPS of AI performance.

Compared with the original Milk-V Jupiter, the new model should bring big CPU, GPU, and AI performance boosts. It also supports faster wired networking. But it also features a […]

linux kernel question regarding #copyfail CVE-2026-31431 I just tested a c version of the exploit (https://github.com/tgies/copy-fail-c) on a riscv64 linux 5.10.4 (milkv-duo) and get
```
[+] target: /bin/su
[+] payload: 2064 bytes (516 iterations)
socket(AF_ALG): Address family not supported by protocol
patch_chunk failed at offset 0
```

I tested it on another risc64 SBC with a newer kernel which gained root but it seems like the exploit doesn't work on this kernel.

I'll do some more digging #riscv #milkv

This took me quite a bit of time, but I managed to boot postmarketOS on a currently unsupported devboard (commonly available for €25-30 where I live).

Little bit proud, but it's not a proper port yet, I ripped the kernel and other parts of the pre-init bootchain (fip.bin, u-boot, ...) from a pre-made Debian image for that device. I have a (mostly working) APKBUILD for that device's userland though. :)

#postmarketos #linux #milkv #riscv64

For those that have been following my #SBC shenanigans for awhile, here is the current status:
1) #Pine64 RockPi Pro is still running strong as a file server
2) Both #MangoPi (quad and pro) have been recycled
3) #RPi zero has been set up to be a CLI sandbox to play around with
4) #OrangePi Zero2w & #MilkV mars both have #Debian installed but are currently collecting dust. I need to find something to do with them.

Unless something really neat comes out WITH robust support, I think my little foray into SBC will come to end; or more likely be way more sporadic.

Milk-V Titan now available for pre-order for $279 (RISC-V Mini ITX motherboard)

The MILK-V Titan is a mini ITX motherboard that measures 170 x 170mm (6.7″ x 6.7″) and should fit in a wide range of PC cases and work with a variety of PC components thanks its PCIe 4.0 x16 connector, support for up to 64GB of DDR4 memory, and M.2 connector for a PCIe 4.0 x4 NVMe SSD.

But while most motherboards with those kinds of features are powered by Intel or AMD processors, the Milk-V […]

Milk-V Titan is a mini ITX RISC-V board with support for DDR4-3200 and PCIe 4.0

The Milk-V Titan is an upcoming mini ITX motherboard with support for up to 64GB of DDR4-3200 memory, an M.2 connector for a PCIe 4.0 x4 SSD, and  a PCIe 4.0 x16 slot for a graphics card or other add-ons.

What makes the Titan unlike most motherboards though, is that it’s powered by an UltraRISC UR-DP1000 processor. The Milk-V Titan should be available soon for $279, although customers who […]

I suppose the #Nvidia #Jetson form factor is a kind of standard interface for #systemOnModule #SBC

There's already a #RiscV #SoM called the #MilkV Jupiter that's supposedly compatible with a #NvidiaJetson #carrierBoard, and now the #radxaN150 with an #x86 chip.

I'd be interested in seeing someone try various Jetson boards with the available modules.

Milk-V Jupiter NX is now available (NVIDIA Jetson NX-like compute module with a SpacemiT K1 RISC-V processor )

The Milk-V Jupiter NX is a computer-on-a-module that looks like a stick of laptop memory. It’s compatible with carrier boards designed for the NVIDIA Jetson NX compute module, but while NVIDIA’s hardware combines an ARM-based processor with NVIDIA graphics and an AI accelerator, the Milk-V module has an 8-core RISC-V processor and a 2 TOPS NPU.

Performance for this little computer will […]

And we have lift off, got #Xonotic working on my #RISCV #RISC_V board, latest #ubuntu release that's supposed to go onto a HiFive Premier P550 works so much better the the provided image be #MilkV ,only downside can't clock the SoC up to it's possible 1.8 GHz with that and fan is annoying as hell.

🎶 please, oooh please, just tell me no.. 🎶

It's 2am and I just want one thing
a strong, handsome, sexy pair of SFP+
in a 10G ethernet switch, RISC-V cores
mod'able, jtag'able, RTOS'able, oooh yes

... so... in all seriousness, there have been lustful hardware-acquisition eyes on this pretty little design since its pre-release marketing materials hit the English speaking OSS internet, and have been watching from afar as its reviews came through, patiently.

I'm not one to say that tonight is the right time to buy a pair, but it's not NOT the right time to buy a pair of Milk-V Vega switches.

*note: I am particularly aware of its limitations, do not expect a production grade switch, mostly want more risc-v hardware to develop with, and general messing around

The docs say that using the "ondemand" power governor it can drop down to 400 MHz, and I'm looking at btop and I see lows of around 500. I also see it go down to 100 or even 24 MHz (this has to be a measurement error).

Next: put it all in the dying desktop's case.

#milkv #megrez #riscv

The operating system is a Debian trixie derivative. Out of the box, it has Firefox 131.0.2 and Xfce 4.18. apt-get install build-essential gave me gcc-14; other items in the repos: nodejs 20.17.0, emacs 29.4, golang 1.23. Elixir's still at 1.14.0 (aside: erlang won't get a JIT for RISC-V any time soon), Python's at 3.12, rustc 1.80.1 (but of course you can use rustup).

Anyway, on to some benchmarks. glmark2-es2 reports a score of 1714, which is surprisingly 38% higher than @geerlingguy 's benchmark of the HiFive Premier P550.

My real test is compiling sbcl; it's not in Debian or Ubuntu's repositories for RISC-V. I bootstrap it with GNU CLISP, and then rebuild it with itself, with sh ./make.sh --with-sb-doc --without-sb-thread. Unfortunately, I believe the build is single-core; I'm not sure if it's possible to use all the cores on my system for it.

Times to rebuild sbcl with itself, including modules:

Lichee Pi 3A (Ubuntu 24.04 derivative): 30 minutes
VisionFive 2 (Ubuntu 24.04):            20 minutes
Megrez (Debian trixie derivative):      12 minutes
Ryzen 9900x (Ubuntu 24.04):              1 minute

So, progress, but a long way to go.

(Incidentally, both the Megrez and my desktop have 6400 memory.)

#milkv #megrez #riscv #sbcl

My 16 GB Milk-V Megrez arrived earlier this week. I had a spare sdcard for the OS image, but didn't have an SSD to install everything on. I went out and bought that today, and hooked everything up using my dying desktop's power supply (650w is overkill for this board).

It booted off the sdcard, and I partitioned the SSD and copied everything over. I manually modified /etc/fstab and /etc/default/u-boot on the SSD to point to the new filesystems, ran u-boot-update inside a chroot, and popped the sdcard.

I did it this way instead of dd'ing the image to the SSD as described in the docs because I wanted a larger swap partition. I wonder if this system supports suspend/hibernate (added to Linux 6.4 for RISC-V).

I/O isn't fast, but it'll work:

# hdparm -t --direct /dev/sda

/dev/sda:
 Timing O_DIRECT disk reads: 1020 MB in  3.00 seconds = 339.89 MB/sec
# 

The board has an M2 slot, but it's for SATA, not NVMe. I had a cheap PCIe to NVMe adapter, so I installed a 1 TB drive on it, and repeated the above exercise to boot off that. The boot order appears to be sdcard, nvme/pci, ssd.

# hdparm -t --direct /dev/nvme0n1

/dev/nvme0n1:
 Timing O_DIRECT disk reads: 1570 MB in  3.00 seconds = 523.25 MB/sec
# 

I'm not sure if it's because the motherboard has a slow PCIe slot (it's PCIe Gen 3) or my adapter is slow.
