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.)

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.

Internet peeps, anyone have a good idea/use for my lil #MilkV Mars #sbc?

I am struggling to find a use for it, and to be honest it has not been that fun to tinker around with.

I prefer to not have it collect dust if possible.

Send me ideas please

#RISCV #needhelp

After some tinkering I was able to get the milk v mars up and running again. Some how between me last using it and now something happened to its ability to boot off micro SD. Luckily I had an 8gig emmc laying around to use.

We'll see how this goes, but I don't expect much.

Just updated my Debian images for MilkV DuoS support.
Many thanks @tllim and #sophgo for giving me a DuoS board to get this done.

Just released a Debian image (and builder) for the Sophgo SG200x chips. (This includes the MilkV Duo256, LicheeRVNano and soon, the DuoS). The Buildroot images they provide are nice, but nothing like having a few thousand packages ready to install at your fingertips on 256Mb of Ram (or 512Mb if you splurged on the DuoS!)

It runs surprisingly well!

Played around with the MILK-V Duo this morning. It certainly feels snappier than the Mango Pi, although that might be because it's running a buildroot image and not a full distro. Idle it uses about 75mA, running `while true; do echo Hello; done` over an ssh connection it pulls 100mA. #milkv #riscv #linux
